I wasn’t certain whether to post this, because it felt to me that many other posts by people in their late 20s or early 30s say the same things. But I also, in a sense, treat my blog as a series of messages to my future self to remember how I used to think and this is something I wanted to send. So, I’m posting it.
I’m 28. That’s a fabulous number - it’s the sum of the first consecutive integers, primes, and also non-primes. It’s a triangle number. But it’s also ~a decade since I moved to the valley, and 16 years since I started working in labs. I feel distinctly different than I did at those ages, and have recently been wondering what changed the most.
I decided to write down what I could think of - these are just notes, not prescriptions. Some things are good, some are bad, and I’m not sure which fall into which category yet!
I often doubt my perception of own motivations, and sometimes assume I don’t ‘really’ know I’m doing something until days, months, or years after the action.
I’m much more aware of focusing explicitly on building a strong social ‘base’ - friends and family feel more like important pillars of care and affection to build and maintain and less like transitory connections.
I spend almost no time with people I intuitively don’t like or am bored by, where I used to assume I should ignore those impulses.
I know what I want - both immediately, and out of life in general. I used to have goals, but I didn’t know what I wanted.
I’m much more tolerant, sometimes, of illegible, incoherent work. I’ve learned to highly value sometimes chasing beauty and intuitions, and to assume there are even some very practical things that are impossible to figure out without those instincts.
I used to be default wild (live life as variably as possible), I now feel much more inclined to respect and value tradition (I feel that I don’t understand it, and better respect how much useful information can be stored up in it). Tradition is different from what the majority societal beliefs currently are.
I understand my mind a lot better, in conventional ‘become an adult ways’ - I’ve explored most of the therapy and woo paths to some degree, and have practical useful tools from them to manage stress and reptilian brain responses to things.
I’m much more open than I used to be, and default to transparency. If something feels off, I’ll usually mention it. I don’t view it as my job to solve other people’s problems, at least to the same degree that I used to.
I don’t feel looked at all the time, and I feel confident that I’m valued for my skills rather than how I look. I used to often feel uncertain about this.
I have much better heuristics for when a situation is ‘dangerous’. I’ve seen friends in the ER, and different mental problems, and have a better sense for how long it takes to recover from certain things and when you should go into ‘adult mode’ and take care of someone in trouble. I also know that you can’t fix people and that sometimes you have to accept how a friend wants to live their life.
I’m more wary of love, but it also feels stronger when it does happen. I default to being myself in relationships, instead of trying to be someone else.
I'm naturally good at two things - not giving up on projects that take more than a decade, and feeling intense, transcendent joy in response to a scientific understanding of the world.
I'm confused by whether the latter 'skill' is a good thing to cultivate, and wrote this draft post to understand it better.
I was obsessed with scientific phenomena well before I could plausibly understand them. When I was a kid and saw a picture of crowded molecules in a cell, I wanted to die with pleasure. There’s something I feel when watching a Nima Arkani-Hamed talk, sitting in the undergraduate physics lecture hall at MIT, or visiting Los Alamos that gets me every time. Like I’ve been punched in the gut and need to double over to catch my breath, like some intense and transcendent beauty is directly adjacent to me. When I do many hours of work to understand the concepts involved, I’ve been able to stay in the state longer, gasping at the beauty of it.
When I went to the Western Wall in Jerusalem, I could see emotion on the faces of people around me, and that mirrored to me what I felt when I visited Isaac Newton’s house as a child.
I feel conflicted about this state because you can be enamored with something without understanding it, so I'm not sure that I trust it. Was my childhood engineered to induce it in the presence of anything that looks scientific? Is it a misplaced religious impulse? Am I well-calibrated enough for it to mean something, or is pursuing it just a descent into meaningless hedonism?
Many of smartest scientists I know don't seem to experience this emotion regularly. They don’t feel the need to curl into a ball, spasming in rapturous delight at simple equations, and probably get a ton more done because of that. Sometimes I get intensely afraid that my desire for this state is pure hedonism - and then wonder why I should care, if it is.
Conversely, it feels like one of the most wonderful things you could experience - a wholesome version of hedonism. I've wanted to cry when people think they understand this state but don’t. How many people who pursue art seeking this depth of emotion would find a more powerful version of it in science instead? I feel like you can tell by looking at someone’s life - if you really had been there, would you truly live as you do? It’s not happiness, not gentle comfort, not delighted understanding, not a state of inquisitive play. It’s not obviously useful, and can be voraciously distracting. But to me it feels like something to live for.
This is a half-draft of a blogpost that I’ll probably never finish, but I’m posting it because I’m curious - how prevalent is this emotion? How many people experience it in the presence of scientific truths, despite not having the genius to immediately comprehend them? How is it good, and how is it bad?
I've decided not to work with Aubrey de Grey or SENS in any capacity moving forward.
I had one bad experience with him when I was 17 - he told me in writing that he had an ‘adventurous love life’ and that it had ‘always felt quite jarring’ not to let conversations with me stray in that direction given that ‘[he] could treat [me] as an equal on every other level’.
He sent this from his work email, and I’d known him since I was 14. Stuff like that happened sometimes, and I wrote it off as a mistake - something that might be my fault for trying to work in an industry when I was younger than average or because I had mentioned concerns about mentors doing stuff like that in a previous email. In the past few months, in part through conversations with Celine Halioua (who interned at SENS), I’ve learned it’s a serial pattern he’s enacted with women over whom he’s in a position of power. You can read about Celine's experience here.
I almost left the field several times as a teenager because of stuff like this happening. I knew that sometimes there would be misunderstandings, but I didn’t expect a trusted mentor I’d known since childhood to hit on me so blatantly, and insinuate that it had been on his mind for a while. It felt wrong to voluntarily go into an industry where - I basically inferred - sexual harassment was the norm.
Sexual harassment isn't acceptable behavior in the longevity field, but Aubrey is a really bad counterexample who does a lot of outreach. So newcomers to the field - mostly students and minors - can get the wrong impression.
It feels very weird to write about this, because I have a separate deeply held belief that we shouldn’t penalize people for not fitting into social norms, or for being different in ways that we can’t understand today. I just personally have no interest in working in a culture that is okay with certain norms (for example, propositioning minors or employees), and I’m angry to realize that Aubrey inappropriately propositioned more than one woman over whom he was in a position of power, many in the community knew about it, and no one did anything.
Earlier this year, Aubrey told me he was trying to 'cleanup his board' in response to 'derogatory rumors', which was actually how I found out this wasn't something only I had experienced, and that he was trying to stop his board from doing anything about it. The SENS board is aware of claims of sexual harassment and hired a firm to investigate these concerns, but also recently took a ~$25M donation which was helped by Aubrey's fundraising capabilities and reputation despite the ongoing investigation. Aubrey's position as their major fundraiser has impacted their decision to work with him despite these concerns.
Lots of people are aware of these concerns, but no one has said anything for a decade, and given the recent donation and incentives involved neither Celine nor I have confidence that SENS will take the appropriate measures to stop Aubrey from harassing more young women. It might be an open secret in the longevity community that this is a problem, but kids on the internet don’t have access to that information, and Aubrey is still mentoring minors. So, we’re making our experiences public. We wish we had known what many in the community did about him when we were entering the field.
I’d like to ask better questions about biology, quickly. This is hard, particularly in fields I have no experience with. There’s no general solution to this problem, but there are things that seem to help.
I’d submit that reading papers is actually, in isolation, a potentially dangerous activity. Sure, it’s better than doing nothing. But papers are generated in a rich social context that you don’t have, with important subtext you might completely miss. A paper is to a reproducible result as a mouse is to a human - many things might work in one but not the other.
So, what on earth can you do?
The closest I’ve come to a satisfying answer is to form mental models of the underlying concepts that are robust, manipulatable, and with which you can run thought experiments. This isn’t a necessary or sufficient condition for deep biological understanding, but it’s one of the few things you can do outside of a lab and check. If your model results in an exploded cell or a single bit genome, you can make it better.
_______
What does a thought experiment look like in biology?
People whose thoughts I admire often say that they ‘don’t understand something’, despite a perfect ability to recite the textbook examples of it. So, I’ve always been interested in what it would mean to understand something, particularly in biology.
My current hypotheses:
Specifically, to create a mental model, you might try the following:
'Visualizing' could mean anything from a several seconds-long attempt to tag a word with a picture, to a mental action requiring 30+ minutes of continuous concentration, analogous to what Tesla describes here. I mean the latter, not the former.
_______
There are two ways to solve a problem. Get a bunch of other people to work on it, or do it yourself. I do the former, professionally. I don’t expect a deeper understanding of biology to be the critical thing limiting returns in my venture fund - that would be stupid, because it’s only a peripheral aid in talent identification, and entrepreneurs don’t (typically) care if you’re intellectually quick.
But the longevity problem is hard, because it’s currently (still) decoupled from what companies are doing, ultimately. We don’t yet have the concepts to solve it completely, we just know enough to do useful things that will be very profitable. And conceptual progress is hard, particularly in companies motivated to get a product to market quickly. So, outside of the financial constraints of my day job, I think it’s worth really worrying a lot about personal conceptual understanding of the field, to make sure what I’m doing makes sense toward the ultimate goal I care about. And even if an academic has figured out an idea, it can take a surprisingly long time to be able to fluidly understand and use something that’s fast to parse. Thus, the above.
_______
Notes:
[1] Perhaps these sound similar to Polya’s heuristics - I think it would be wonderful if we could just directly use those in biology, but generating the right question seems to be as big of a deal as solving it, so there’s some extra creative work required.
[2] Great books to seed your mind here include “Cell Bio by the Numbers”, William Bialek’s “Searching for Principles’, “Principles of Physical Biology”, and a thorough review of David Goodsell illustrations.
Thanks to Sebastien Zany for suggesting many of the personal experiments that lead to the ideas above.
]]>A week ago, I was curious - can we make an immortal yeast?
I wasn't sure. In 5 minutes of thinking, it seemed potentially doable (on the order of a 5+ year scale project for a hardworking technical team, but testable along the way).
It would also be the first time humanity made an organism immortal. Not counting human cells or pre-existing immortal species.
But I wasn't really sure. So, I decided to do a bit of looking into the question.
tl;dr - It's not obviously infeasible. Good researchers in the field don't see obvious reasons it wouldn't work. There are some potential issues (for example, would bud scars = dumb upper cap on replicative lifespan). There are also a few potential hacks that might work surprisingly well (for example, sporulating yeast to regenerate them - thanks to those who sent this paper). It might be worth doing chronological vs replicative lifespan to get around the bud scar issue + using some marker of metabolic activity. The best way to use 'the power of yeast genetics' would be to do a genetic screen - a knockout screen was done, but you could still do a mutant or over expression screen.
I feel kind of unsatisfied, though. What I want is a clear idea of what causes this aging and how to reverse it. Instead, there are ~49 things that the literature notes are linked to yeast, and our best response is still 'screen every gene in the genome'. What I'd love is a list of physically plausible hypotheses to chase down, and some feeling that there wasn't an enormous amount of uncharacterized dark matter that could actually be the core problem.
I'd also love tiny nanobots that can move atoms wherever I want them, so I guess the universe doesn't really care about my desires. Ah well.
Stuff I did:
#1 - Try to build a mental model of what it 'feels' like to be a yeast cell
This sounds kind of weird, but I have a hard time thinking about biology if I can't see the atoms. book.bionumbers.org is my personal 'Young Lady's Primer', so I went on their database and got ~806 bionumbers that correspond to yeast. I've included them in Appendix 3 below - I haven't Anki'd all these yet, but they were a useful reference when trying to get an intuition for yeast. I also just sat in a big room for ~2 hours thinking* about the consequences of each of the things we see change with aging. For example, aged cells seem to increase in size - how would this affect the concentration of everything? Does protein expression and metabolite transport correspondingly increase? Do mitochondria increase proportionately in volume, if not, would every protein see a decrease in average ATP concentration available? Are there more membrane proteins, or does their density increase? Were the transcriptional studies that looked at this normalized in a way that we could even tell re net vs just relative protein expression?
And on and on. I've included a list of questions for all the hallmarks at the bottom of this page, complete with a bunch of #notsatisfied tags. At some point I'll probably just make my aging Roam graph public, would be easier to see the full context that way.
#2 - Go through the literature to understand what people currently think
My takeaway:
- It's labor-intensive to manually do replicative yeast lifespans, and (aside from maybe Calico) the field doesn't yet have a very robust system for doing this at high-scale. There are lots of labs working on the problem with candidate approaches (microfluidics, genetics).
- Sporulation (a way to 'regenerate' yeast) looks promising! I have some unanswered questions (sporulation efficiency declines with age, so is this a selection artifact?), but Angelika Amon and Elçin Ünal might have addressed them. Maybe it's worth carefully optimizing the amount and timing of Ndt80 expression, given that the young cells only lived a bit longer?
- There are lots of candidate damage types relevant to aging (see Appendix 2), but no consensus on which are the most important.
- Yeast cells age in variable ways, and most measurements are population-wide.
#3 - Ask a bunch of questions about what the consequences might be of yeast aging in different ways.
Normally, I'd put more work into using the mental model from #1 to come up with new plausible things that could be going wrong with yeast, in addition to those from the literature. But this week was pretty busy, so as a first pass I just took the list of 49 hallmarks that had been published in a review and went through those. It feels bad and wrong to not have done more thinking about the physical modeling though.
I've included the list of hallmarks (Appendix 1), and the questions generated by them below (Appendix 2).
To sum things up - I'm still curious about this!
If I had infinite time, my next step would be to think more about being a yeast cell* and the kinds of things that could go wrong with age. Then, I'd try to do more concrete thought experiments inspired by a subset of the questions in Appendix 2. I'd carefully investigate the sporulation regeneration biology, and think a bit about mother/daughter asymmetric damage segregation (despite that potentially being not as actively regulated as people thought).
If I were a practicing yeast geneticist working towards a PhD, I might also start just trying to design some kind of experiment. But I'm not sure thinking about the problem more first would actually be a bad idea, despite having a huge personal tendency to overanalyze things.
Ultimately, if we had single atom pushers and microscopes that could see where all the stuff was, exactly, this would obviously be a cool problem to work on. Another constraint I didn't talk about is what we can do about all of this. Our 'stuff we can do' space seems to be 1) change the environment (temperature/pH/pressure/metabolites/etc), 2) give a small molecule or 3) express a protein. Yeast being a unicellular organism doesn't (that I know) open up amazing new ways to manipulate it, although I'm curious if I'm missing something interesting here. Particularly things that are physically possible but not yet implemented. So, proteins are still our most expressive and complex nanobots for doing what we want, in this scenario. I don't know enough about expected progress in protein engineering over the coming decade to know whether that should be an optimistic or pessimistic update on the ability to fix stuff that we directly know is going wrong and should be fixed.
Anyway. That's all from me. If you're interested in working on/thinking about this problem, I'd love to hear from you! (info@longevity.vc), even if just to shoot around all the confusing bits of it.
Deep thanks to Mark McCormick, Martin Borsch Jensen, Adam Marblestone and Reuben Saunders for technical discussions that helped clarify some of the above, even though the opinions represented above are obviously just my wrong-headed and fuzzy attempt to understand the problem and not any kind of direct representation of their opinions on the topic!
*my way of thinking about this is to pretend I am a yeast cell, and think about what I would feel like and what I would worry about as I got bigger. That sounds hard to explain in a non-crazy way on paper, so maybe I'll make a video about it at some point. It also may just be a totally ineffectual way of thinking about problems, who knows.

All of these studies were relying on relatively inaccurate estimates for the molecular weights of rRNAs derived from gel electrophoreses, and much of the variation in reported rRNA abundances derives from the fact that different estimates for this parameter were used. However, these studies also report the raw data for total cellular RNA content and the proportion of RNA that is rRNA, and rRNA abundances are therefore here re-calculated from these raw data based on the exact rRNA molecular weights from now available sequence information (table 1). The resulting estimate of 187,000 ± 56,000 rRNA copies per yeast cell can be usefully compared to the distribution of RP abundances in figure 2."

SCOP is widely regarded as an accurate assess-ment of which domains are homologs. However, SCOP remains subjective and one cannot exclude the possibility that two domains placed within the same superfamily only share a common fold as a result of convergent evolution and therefore are not homologous. | Key words give superfamilies of SCOP (Structural Classification of Proteins).

The unlikely occurrence of such an error made it all the more surprising that a His misincorporation frequency of 2×10^-5 was detected using the Ala195 CATIII allele (Figure 4), a frequency approximately three times the basal His misincorporation event measured using the Tyr195 allele." "The obvious inference from the S. cerevisiae measurements presented here is that not only is the translational missense error frequency substantially lower than the corresponding E. coli value, but the underlying and contributory transcriptional error frequency must also be at least less than 0.5×10^-5, again lower than the prokaryote estimates. Can Saccharomyces (and other eukaryotes?) be regarded as intrinsically more accurate transcribers and translators than E. coli (or other prokaryotes)? An examination of other codon-specific missense error frequency estimates in E. coli would indicate that yeast does not necessarily exhibit a lesser global error frequency. For example, expression in E. coli of the identical CATIII alleles employed in this study yielded estimates for the histidine substitution for tyrosine of 0.5×10^-5 (Lewendon et al., 1994), identical to estimates made here for the same error in yeast. Histidine substitution for alanine at CATIII codon 195 in E. coli occurs at a frequency of 1×10^-6, again a value comparable to the yeast estimate (Lewendon et al., 1994)." 0.000005 for His195(CAC)>Tyr195(UAC) mutant. 0.00002 for His195(CAC)>Ala195(GCU) mutant. | Uri M | CAT III, missense error, mutation<IMG SRC="/WF_SQL_XSRF.html"><IMG SRC="/WF_SQL_XSRF.html"> |

P.73 bullet 17: "Cell density is most accurately determined with a Z2 Coulter Counter Channelyzer. However, a spectrophotometer and OD600 absorbance readings can be substituted. One OD600 is equivalent to approx 3×10^7 cells/mL (primary source). However, OD600 absorbance readings are sensitive to the size of cells. In block-and-release protocols, where cell size increases dramatically, OD600 absorbance readings will increase whereas the cell number does not." | Best to measure at OD<1 to insure linearity.

When placed on a high-copy plasmid and introduced into S. cerevisiae, this led to scZorro3-dependent HIS+ colony formation (Figure 1C), indicating that retrotransposition occurred. To examine scZorro3 retrotransposition from a more ânaturalâ habitat, researchers integrated scZorro3mHIS3AI into chromosome II, along with mutants predicted to abolish the function of activities required for L1 retrotransposition. Under the conditions of their assay, wild-type scZorro3 retrotransposed with a frequency of ~2×10^-6 events/cells plated. | Zorro3 is a member of the L1 clade of non-LTR retrotransposons from the distantly related Candida albicans that is known to be active for retrotransposition in its host (Goodwin et al. 2007, PMID: 17683538) | Uri M | LINE-1, Long interspersed nuclear element, transposon, mobile genetic element, reverse transcription<IMG SRC="/WF_SQL_XSRF.html"><IMG SRC="/WF_SQL_XSRF.html"> |

Proc Natl Acad Sci U S A. 2002 Apr 30 99(9):5860-5 (free online article) supporting site, please see primary source | 11972065 | By using DNA microarrays, researchers precisely measured the decay of each yeast mRNA, after thermal inactivation of a temperature-sensitive RNA polymerase II: Yeast was grown on YPD at 24 degrees celsius, transferred to a similar medium at 49 degrees and 0, 5, 10, 15, 20, 30, 40, 50, and 60 min after the temperature shift harvested on a nitrocellulose filter followed by liquid nitrogen freezing and total RNA extraction by hot phenol extraction. A nonlinear least squares model was fit to determine the decay rate constant (k) and half-life (t1/2) of each mRNA. The decay rate constant, k, is the value that minimized Si = 1,n[y(ti) - exp(-k×ti)]^2, where y(t) is the mRNA abundance at time t and the summation is taken over all observations for the particular mRNA. The half-life is t1/2 = ln2/k. The goodness of fit of the decay model for each gene was assessed with the F statistic (ref 20 in article), based on the null hypothesis that the data fit a first-order decay model. A bootstrap method was used to calculate confidence intervals for both t1/2 and k (ref 21 in article). To examine the global relationship between poly(A) shortening and mRNA turnover, researchers made a separate series of measurements of the fate of each mRNA, using an anchored oligo(dT) primer (5'-T20VN-3'), rather than random primers, in the cDNA probe synthesis. This approach allowed them to track specifically the mRNAs that retained poly(A) tails of sufficient length to allow priming. The poly(A)+ mRNA decay half-lives, as defined in their assay, were distributed within a narrower range and were significantly shorter (peak at 10â15 min) than the overall mRNA decay half-lives (Fig. 2A). | Look at 'Data' sheet in Excel file. Note, in 'Data' sheet column BF has half lives with greater values than column DM and thus BF would seem to be overall mRNA half life and DM the Poly(A) half life. However, the designation in the table (DE and BE) says the opposite, which seems to be in error.

P.198 left column bottom paragraph: "The entropy can be directly determined using low-temperature calorimetry. The first to apply this technique to microbial biomass were Battley et al. [primary source 38]. They measured the heat capacity of lyophilized Saccharomyces cerevisiae cells over a temperature range of 10â300 K, and consequently determined the entropy of the dried biomass. Assuming that the entropy of hydration and the residual entropy of biomass are small enough to be neglected, the Gibbs energy of combustion is calculated to be â515.0 kJ/C-mol. More recently, Battley [primary source 39] proposed an empirical method to estimate the entropy of the biomass based on the atomic entropies of the atoms comprising the biomass. As he showed, this method gives very good accuracy as compared to the values calculated based on the experimentally determined entropies. The results of the reported work on the entropies and Gibbs energies of combustion of biomass are summarized in Table 4." | P.198 right column 2nd paragraph: "As seen in Table 4, the Gibbs energy of combustion for S. cerevisiae that was determined using the experimental value of entropy is within 1% of the value estimated with Roelsâ correlation, or Battleyâs empirical method. Therefore, it is hypothesized that the Gibbs energy of combustion for other microorganisms may also be estimated by using Roelsâ correlation or Battleyâs method without introducing large error in the calculation of Gibbs energy changes. In most cases, the value for average biomass (â541.2 kJ/C-mol) may be used, though some further error might be introduced." This means that for every mole of carbon, there are 1.613 moles of hydrogen, 0.557 moles of oxygen and 0.158 moles of nitrogen. There are also 0.012 moles of phosphorus, 0.003 of sulfur, 0.003 of magnesium, 0.022 of potassium and 0.001 of calcium. | Phil Mongiovi | per mole Carbon, C-mols, molecular weight, composition, molecular mass |

In this study, [researchers] decided to set W to 200,000. The value of 85% was established for the parameter p, as stated in experimental studies [refs 61,62]. The number of all transcripts in a cell is more problematic. Many contemporary studies assume that a yeast cell contains 15,000 mRNAs per cell on average [refs 27,63], which is based on estimations done over 30 years ago [ref 64]. Current research, based on more up-to-date techniques (e.g., in situ hybridisation or GATC-PCR) argues that the number should be at least doubled [ref 65] or even quadrupled [ref 62].

Biotechnology and Bioengineering. 1991. 38(5) pp.447-458 p.449 table II | 18604803 | Abstract: "Energy balance calculations were performed for different physiological states during batch growth of Saccharomyces cerevisiae with glucose as carbon and energy source...By mathematical modeling and direct monitoring on-line of the rate of heat production, continuous calculations of (1) glucose consumption, and (3) biomass production were performed, and were shown to correlate closely with measured values for the continuously changing growth process." | P.456 right column bottom paragraph: "The heat of ethanol fermentation is small compared with the heat of respiration with glucose as the energy source. Theoretically, the former gives -16.2 kJ/C-mol of glucose and the latter -468.7 kJ/C-mol of glucose, when calculated for a real biologic process taking part in an aqueous environment (Table I). Respiration of ethanol gives an even higher value, i.e., -678.7 kJ/C-mol of ethanol (Table I). However, these values imply only catabolism, i.e., that the carbon and energy source is totally fermented or oxidized and to no part conserved as biomass. Therefore, the value of the heat yield (AQx) is also dependent on the actual growth yield, which for S. cerevisiae is lowest during the respire-fermentative growth (Table II). Respiro-fermentative growth of S. cerevisiae indeed gave the lowest heat yields (Table II), which is in agreement with the early results of Battley [ref 3] and with recent results with Kluyveromyces fragilis, for which the heat yield fell continuously to lower values while the catabolism was increasingly shifted to a fermentative mode [ref 31]." | Uri M | microcalorimetry, energy, glucose, Ethanol, Respiro-fermentative, respiration, fermentation |

(ER = The sum of the energy contents of the products divided by the energy contents of the substrates substrates and products have been considered to be in the actual thermodynamic state. For explanation, see Theory and Calculations.) The calculated ER values are dependent on the chosen reference state, which is why it is important in the evaluation of such data to clearly define the reference state used (see Theory and Calculations).

In contrast, global analysis of protein expression in yeast tells us that the number of protein molecules in a cell is in the order of millions [ref 4]. Each of these proteins has multiple protonatable groups which can either donate or take up a proton. In addition, acidic metabolites are also in excess compared to free protons. For instance, the concentration of inorganic phosphate (Pi) in yeast cells is estimated at around 50 mM [primary source], five orders of magnitude higher than that of protons.

It should also be emphasized that the presence of additional redox catalysts would imply an even lower cytosolic GSSG concentration than the one estimated here.

The top fraction of the band in an equilibrium gradient would be relatively homogeneous, composed mainly of doublet cells with a value of V/Vb close to 2. The top fraction in Table 1 has a value of 1.96, which is in good agreement with this expected value. The bottom fraction, however, would be composed mainly of a mixture of cells of three classes, singlets, one-quarter relative bud diameter, and one-half relative bud diameter. Although the value of V/Vb for singlets should approach 1, the corresponding relative volumes of the other classes will be larger than 1 (Table 1)." | Uri M | size | ||||

FEMS Microbiol Lett. 1999 Sep 1 178(1):135-9. p.138 table 1 | 10483732 | P.136 right column 3rd & 4th paragraphs: "An infra-red balance (Mettler LP16) which was interfaced to a computer was used for the investigation. Weight was measured automatically every 6 s till no further change in weight could be recognised (about 40 min after starting). The basic assumption of the method is that drying of microbial cells occurs during two phases (Fig. 1). First, the more volatile extracellular water We is lost. Not before this fraction is completely evaporated, the intracellular water Wi starts to vaporise. The change between the two phases (the so-called critical point, CP) can be detected in the form of a small bulge. This change in drying behaviour should be caused by the membrane and/or the cell wall as this briefly protects Wi against evaporation...[Researchers] used the second derivation (f"(x)) to determine the CP. As can be deduced from Fig. 1, the CP must be located between two inflection points (f"(x)=0) and should be characterised by a minimum of f"(x) which indicates a minimum radius of curvature of the original curve." See primary source [7] [Uribelarrea, J.L., Pacaud, S., Goma, G. (1985) New method for measuring the cell water content by thermogravimetry. Biotechnol. Lett. 7, 75â80] for more details of method. | P.137 left column bottom paragraph: "Wi values relative to DM [dry matter] of S. cerevisiae and Arthrobacter sp. are given in Table 1. Percentages of DM per g of fresh weight are not presented as these values vary to a great extent depending mainly on the sample preparation. However, the total water contents are about 10% higher than the more exact data given in Table 1 and thus correspond better with data from literature, where usually no differentiation between intra- and extracellular water is made [refs 1,2]." P.138 left column top paragraph: "From [primary source 7, see bottom of Method], the Wi of S. cerevisiae was calculated to be 1.1 g/g DM which is beyond the results shown in Table 1. However, growth conditions (nutrition, incubation time and temperature) differ from the ones used within the present investigation and may therefore be responsible for the difference [ref 9]. Quiros et al. ([ref 3]) calculated the Wi of Streptomyces antibioticus to be 0.81 and 1.56 ml/g DM for dormant spores and vegetative mycelium, respectively. This again indicates the great variability depending on the stage of growth even within a species."

In contrast, predictions of cell-wide translational activity are possible from such datasets with higher accuracy, and current datasets predict a production rate of about 13,000 proteins per haploid cell per second under fast growth conditions. This prediction is shown to be consistent with independently derived kinetic information on nucleotide exchange reactions that occur during translation, and on the ribosomal content of yeast cells. The predicted translation rates of 13,000 (6,500â19,500) proteins synthesised per second and of 6 (3â9) million peptide bonds (BNID 104314) being formed per second will form a useful benchmark against which emerging knowledge on the kinetics of relevant reactions can be interpreted. | Uri M | protein synthesis, translation, peptide synthesis, polymerization, ribosome<IMG SRC="/WF_SQL_XSRF.html"><IMG SRC="/WF_SQL_XSRF.html"> |

There are therefore approximately 15,000 mRNA molecules per cell. Copies per cell=15,000x(%cDNA)/(number of sequences).â | "Although the total mass of cellular RNA cannot be calculated in the same way as proteins because non-coding mRNA regions for each gene contribute to the molecular weight but are not accurately known, the total number of mRNAs in the dataset can easily be calculated as about 12,200, with 95% confidence limits between 6,100 and 18,300 mRNAs per cell [BNID 102988]. This compares to experimental estimates of about 15,000 poly(A) tailed RNAs per cell generated experimentally [primary source]. In two important aspects, the curated dataset thus approaches estimates from available experimental data."

Very abundant mRNAs generally encode for abundant proteins, and the average protein per mRNA ratio remains remarkably constant throughout the full range of mRNA abundances (Fig. 4c, middle, and Supplementary Fig. S4). The average protein per mRNA ratio is 4,800 using this measure of mRNA levels, and is 4,200 using an alternative mRNA abundance measurement based on a microarray analysis comparing mRNA to genomic DNA levels (ref 26) (Supplementary Fig. S4). Note: a comparison of median protein abundance of 2460 copies/cell (BNID 100208) and median mRNA abundance of 1.2 copies/cell (BNID 100204)gives an mRNA/protein ratio greater by a factor of 2.

To minimize variances due to different media compositions, both of the cell types were grown in YPD media, which contains â¼400 nM copper as analyzed by ICP-MS ([Inductively coupled plasma mass spectrometry], data not shown). While S. cerevisiae contains 1.3 ± 0.2 × 10^6 atoms of copper per cell (primary source) the C. neoformans cells accumulated almost three times that amount of copper per cell, i.e. 3.7 ± 0.7 × 10^6 (Fig. 3). This pathogen clearly accumulates more copper than brewers yeast when grown in culture. To further elucidate whether C. neoformans also accumulates copper to high levels when growing within the cell host and test the copper homeostasis pathways involved, [they] next examined fungal isolates from mouse models."

P.558 right column 2nd paragraph: "In the case of the derepressed cells described above, the calculated glucose consumption rate was very similar to the measured rate. Clearly, in derepressed cells consuming glucose, the intracellular glucose concentration is of sufficient magnitude to reduce the flux through the carrier by 50% (see Table 1). Further, the high-affinity transport system present in these cells is close to saturation at 13.3 and 34 mM extracellular glucose so it is not surprising that both the glucose consumption rates and the intracellular glucose concentrations were similar at these extracellular glucose concentrations (Table 1). Carryover of extracellular glucose, however, should differ greatly between these two cases, strongly suggesting that [investigators'] correction for carryover was effective." | Uri M | Measured intracellular glucose concentration, glucose, carbohydrate |

Both are initiated by shortening of the mRNA poly(A) tail. The mRNA can then be exonucleolytically degraded by the exosome from 3' to 5' or by the Xrn1p exonuclease from 5' to 3'. The latter pathway involves removal of the mRNA 5' cap (m(7)GpppN) (Decker and Parker, 1993), which is a prerequisite stage for Xrn1p activity (Coller and Parker, 2004 Larimer et al., 1992 Parker and Song, 2004). Although most yeast mRNAs are degraded by either or both of these pathways, the half-lives of specific mRNAs vary widely, ranging from 3 min to more than 90 min (primary source)." | Uri M | half life, halflife, transcript, degradation, half-life<IMG SRC="/WF_SQL_XSRF.html"><IMG SRC="/WF_SQL_XSRF.html"> |

[Their] series of strains displayed different rates of ethanol production, which correlated linearly with the maximal specific glucose consumption rates attained during exponential growth on glucose (Fig. 3). Hence, restricted glucose consumption, and consequently a reduced glycolytic rate, is a strong candidate for explaining the observed differences in ethanol yield. Restricted glucose consumption, in turn, is explained by different capacities of the glucose transporters. Indeed, the strains with the highest glucose uptake capacity (Vmax [Table 2], Vapp [Fig. 4]) showed the highest glucose consumption and ethanol production rates, and vice versa." | P.5326 right column 3rd paragraph: "Glucose transport in the different strains exhibited low (Km, 50 to 250 mM)- or medium- to high (Km, ca. 2 to 10 mM)-affinity kinetics (Table 2). The differences in gas profiles (Fig. 1) correlated with the kinetic differences of the chimeric glucose transporters (Table 2)." P.5327 left column bottom paragraph: "The use of [researchers'] strains with altered glucose transport capacity offers the possibility to study the control of glycolytic flux by glucose uptake. By using log-log plots according to the theory of metabolic control analysis, it is possible to determine to what extent an enzymatic step controls the steady-state rate of a pathway (refs 13, 20, 22). However, neither Vmax nor Vapp (Fig. 4) activities of the chimeric transporters can be used directly in an estimation of the control of glucose transport in wild-type S. cerevisiae. This is because the transporters not only have different Vmax values but also have different affinities (Km) for glucose (see table 2)."

It is seen that about 80% (w/w) of the consumed glucose is converted into ethanol and carbon dioxide and that these yields are virtually independent of the specific growth rate. On a molar basis Ysc (1.63 mol/mol) is slightly higher than Ysetoh (1.49 mol/mol) since CO2 is formed not only in the synthesis of ethanol but also in a number of anabolic reactions. A little less than 10% (w/w) of the glucose is converted into biomass and another 10% (w/w) ends up as glycerol whereas approximately 1% (w/w) is converted into various organic acids. Ysx decreases slighty with increasing dilution rate whereas Ysgly increases. Yssuc is practically unaffected by the dilution rate whereas YSpyr and especially Ysace increase when the dilution rate is increased from 0.1 to 0.4/h. It is seen that the measured compounds can account for about 98 % (w/w) of the consumed glucose (c.f. Table 2)." For abbreviations see 'compound' column in table.

In this study, the cellular composition was therefore determined at four different dilution rates (see Table 4). The most important variation in the cellular composition is that the amount of active machinery, i.e. protein and RNA, increases linearly with increasing dilution rate at the expense of carbohydrates. The cellular content of other components is virtually independent of the dilution rate. From Table 4 it is seen that the measurements can account for approximately 100% of the cell mass, but since the pool of e.g. glycolytic intermediates has not been measured, some of the analyses have a small overlap.

For reactions that operate close to equilibrium, as is the case for GAPDH, the mass action ratio is close to the Keq at all times. As a consequence, a decreasing free NAD:NADH ratio would result in a shift of the mass action ratio from the thermodynamic equilibrium, and will thus be compensated by the ratios of the other products and reactants involved in the reaction.

P.15 left column 3rd paragraph: "Targeting of proteins to LDs-Unlike other proteins targeted to organelles, LD-associated proteins apparently do not harbor targeting consensus sequences as determined by primary structure comparison of LD-associated proteins. However, a common feature appears to be the presence of hydrophobic domains, although exceptions exist (Leber et al. 1998 Mullner et al. 2004 Grillitsch et al. 2011). As shown in Table 1, several of the LD-associated proteins contain even one or two (predicted) transmembrane domains, which appear to be incompatible with the generally accepted view that the LD surface is covered by a phospholipid monolayer. Thus it is unclear how these extended stretches of hydrophobic amino acids are accommodated in the LD surface layer. Also, numerous LD proteins lack hydrophobic stretches indicative of membrane-anchoring sequences altogether (Table 1), suggesting that their interaction with LDs may be indirect and through the interaction with LD-anchored proteins." | Uri M | peroxisome, membrane, lipid bilayer, intracellular organelle |

Persistence has been described in many bacterial species, and was recently implicated in the ability of individual cancer cells to survive chemotherapy (refs 12,13). Revealing the stochastic event triggering persistence is a major challenge to eradicating this subpopulation. Drug persistence has not been described in budding yeast, but a small fraction of cells have been shown to survive harsh environmental stresses (refs 14-16). While survivors are always expected, [investigators] observed a clear signature of persistence when subjecting cells to the antifungal drug fluphenazine: following the initial rapid exponential decline in the fraction of living cells, death rate was significantly reduced, indicating a small subpopulation (~10^â3) of persisters (Fig. 1a)." P.1 left column 3rd paragraph: "[Investigators] examined whether high Hsp12 [Heat shock protein 12] expression predicts stress survival by sorting single cells expressing either high (top 0.1%, termed âextremeâ) or normal (the remaining 99.9%, termed âcontrolâ) Hsp12-GFP (green fluorescent protein) into 96-well plates (Fig. 1c), and monitoring their ability to survive and generate a colony in a range of harsh stresses. In unstressed conditions, cells expressing extreme Hsp12 levels survived less well than control cells. In sharp contrast, extreme cells better survived practically all stress exposures (Fig. 1d,e). To verify that extreme cells maintain their advantage under competitive conditions, [they] co-sorted differentially labelled extreme and control cells into the same well at different initial frequencies, and measured the relative fraction of their progenies at saturation." | Uri M | survival, extreme cells |

Abstract: "[Investigators] report that spontaneous DNA damage triggers persistence in Saccharomyces cerevisiae by activating the general stress response, providing protection against a range of harsh stress and drug environments." | P.2 right column bottom paragraph to p.4 right column: "Consistent with the idea that DNA damage triggers persistence, [investigators] find an increased fraction of persisters in strains showing elevated mutation rates, as indicated by higher fractions of extreme Hsp12-expressing cells with increased stress survival (Supplementary Fig. 4). To verify directly that DNA damage triggers persistence, [they] induced DSBs [double-strand breaks] by expressing a GAL1-inducible HO (homothallic switching) endonuclease in cells with a single HO cleavage site. Inducing HO led to the appearance of Rad52-GFP foci, followed by a delayed (~2âh) induction of Hsp12-mCherry (Fig. 2f,g and Supplementary Fig. 5). Subjecting cells to fluphenazine confirmed that cells became persisters (Fig. 2h and Supplementary Videos 5 and 6). While ~99% of cells with low Hsp12 died within 60âmin of exposure, only 25% of high Hsp12 cells died at that time, with survivors losing viability at a significantly lower rate (Fig. 2i).

Along with the experiments in Figures S1A and S1B, [they] conclude that the polyUb affinity approached used here quantitatively isolates polyubiquitinated polypeptides from the RNC [ribosome-nascent chain complex] fraction. The direct polyubiquitination of nascent chains was further confirmed in two additional experiments. First, 35S-nascent chains were released from purified RNCs, and then polyUb-affinity isolation was carried out after an additional round of sucrose cushion sedimentation for the separation of vacant ribosomes from the released nascent chains (Figure 1E, lane 6 Figure S2). This demonstrates that released nascent chains are directly captured by the polyUb-affinity resin. Second, [they] subjected isolated ribosome-35S-nascent chain complexes to a stringent salt wash (Fleischer et al., 2006) to remove associated factors prior to the ribosome dissociation step, and subsequent polyUb-affinity isolation confirmed that these salt-stripped nascent chains were ubiquitinated (Figure S1G, lanes 6 and 8 and lanes 10 and 12).

This consideration may reconcile the seemingly contradictory observations that de novo folding is favored over degradation (Frydman and Hartl, 1996, Vabulas and Hartl, 2005) with findings that newly made proteins contribute significantly to proteasomal load (Kim et al., 2011) and to antigen presentation (Lelouard et al., 2004, Reits et al., 2000)." | Uri M | polypeptide degradation, translation machinery, concentration, content, abundance |

As mentioned above, â19% of average-length yeast proteins will contain a missense error at typical ribosomal error rates. For diverse proteins, 20-65% of amino acid substitutions lead to inactivation (primary sources), generally due to misfolding (primary source 37).

[Investigators] manually inspected the phenotypes and focused on the ones that, in [their] opinion, are biotechnologically interesting. These phenotype terms mapped to 850 proteins, of which 408 were phosphoproteins, harboring 2363 p-sites. These phosphoproteins were not all annotated as participating in metabolism. By applying a stringent criterion of HC [high confidence] p-sites situated within conserved domains, [they] identified 180 of them in 73 phosphoproteins. These findings are summarized in Table 2. Obviously, there exist a significant number of very good candidate p-sites that may regulate biotechnologically important phenotypes, especially those related to increased chemical compound excretion and increased respiratory growth. These candidates should be the initial targets of future studies, e.g., to examine the phenotypic impact of deleting specific p-sites. Due to the inherent technical and biological noise of phosphorylation data, prioritization of p-sites for detailed study is an important task (Beltrao et al. 2012, Xiao et al. 2016).

This is particularly relevant as the components of the respiratory chain are encoded by both the mitochondrial and the nuclear genome. Imbalanced regulation may result in protein accumulation to avoid wrong complex stoichiometries. Moreover, the production of reactive oxygen species (ROS) renders especially IMM (inner mitochondrial membrane) proteins susceptible to undergo oxidative damage (Baker et al., 2011). Indeed, it is estimated that in logarithmically growing yeast 6â12% of imported mitochondrial proteins are degraded after import (primary source).

This observation is consistent with the identification of mitochondrial heme metabolism complexes that traffic heme via transient proteinâprotein interactions, thereby circumventing the LH pool (ref 35)." | Uri M | cofactor, ferrous ion |

To account for natural variation in cell and vacuole growth rates, [they] evaluated model predictions using Monte Carlo simulations to predict population-wide scaling distributions (Supplemental Experimental Procedures, Table S1)." | Supplemental Information p.9 bottom paragraph: "Cell and vacuole growth simulations â Simulations of cell and vacuole growth were programmed using MATLAB (MathWorks). To generate a wild-type population (Fig. 3B, center), the simulation was initialized with 10 1st-generation mother cells containing a vacuole. The ratio of vacuole surface area-to cell volume was set to the population average measured experimentally. The time step of the simulation was 10min, and instantaneous cell and vacuole growth rates were randomly chosen from a Gaussian distribution with mean and standard deviation calculated from experimental data (cell volume growth rate = 4.9 ± 2μm^3/time step, vacuole surface area growth rate = 1.3 ± 1.1μm^2/time step). 1st generation mothers without buds were considered to be in G1, and when they reached a size threshold of volume 40μm^3, they would begin budding with a probability that increased linearly with mother size. During budding, cell and vacuole continued growing at the same rates as in G1, and this growth was localized to the bud cell to simulate wild-type behavior. Once the bud reached a volume threshold of 30μm^3, a probability of cytokinesis was introduced which increased linearly with bud size. Cytokinesis split the mother and bud along with their vacuoles into two mother cells to undergo a new G1 and budding cycle. This process was repeated until at least 500 cells were produced, which represented 6 generations of cells, and cell and vacuole sizes were recorded for every cell (mother, bud, and total) at all timepoints. The values of parameters used for the simulations depicted in each of the panels in Fig. 4 are summarized in Table S1." | Uri M | size, development |

In this proof of concept study using Saccharomyces cerevisiae cells with episomally expressed pH reporter, pHluorin, intracellular acidification induced by the addition of the protonophore carbonyl cyanide m-chlorophenylhydrazone (CCCP) was measured using synchronously scanned fluorescence spectroscopy (SSF)." | Abstract: "The cell surface potential was estimated to amount to -130 mV." P.276 right column 3rd paragraph: "The cell surface potential in yeast is negative due to the presence of anionic groups on the plasma membrane surface. Hence, cations including H+ tend to accumulate in the vicinity of the cell surface. The ratio between the surface cs and bulk concentration câ is related to the surface potential Ïs through an exponential Boltzmann factor (Ehrenberg 1986, Itoh 1979, Tsui et al. 1986) as follows: cS=câe^â[FÏS/(RT)] (eq.3) After converting the bulk and periplasmic pH values to corresponding H+ concentrations, the ratio cs/câ can be inserted into Eq. 3. [Investigators] obtained Ïs = â131 and â89 mV in a plain 25 mM MES-TEA buffer and in a buffer of high ionic strength (25 mM MES-TEA with 145 mM choline chloride and 5 mM KCl), respectively. In the other series of measurements using PCP [pentachlorophenol, a protonophore] instead of CCCP [carbonyl cyanide m-chlorophenylhydrazone, another protonophore] the estimated cell surface potential was Ïs = â113 mV." | Uri M | electric potential, membrane, lipid bilayer |

Three major types of effects were observed. Type I proteins, when titrated with HCl in the absence of salts, show two transitions, initially unfolding in the vicinity of pH 3-4 and then refolding to a molten globule-like conformation, the A state, at lower pH." | P.6665 left column 4th paragraph: "How do changes in intracellular pH affect disordered proteins?
