Some kinds of biological stress can make cells live longer - such as nutrient starvation. One such mechanism:

This is not my field. But, surely, people who decide to use intermittent fasting had a reason for doing this. Would this not have biased the comparison between the populations?

How do cells clean up misfolded proteins when they divide?

This study finds that the cleanup crew includes the ER chaperone BiP and the proteasome, and kicks in right as cells finish dividing. Surprisingly, one major cell cycle regulator isn’t involved.

A very interesting (and very thorough) case for Alzheimer’s as (of all things) a disease of lithium deficiency. This one’s worth taking seriously, I believe:

We might have been looking at atherosclerosis the wrong way all these years. Is the cause a bacterial metabolite?

Free radicals and antioxidants: appealing to magic

Our short paper argues that molecules cannot be classified as good or evil. Limited evidence supporting the consumption of antioxidants or superfoods and such interventions risk disrupting fundamental redox processes.

Free radicals and antioxidants: appealing to magic
In biology, there are no good or evil molecules. There is limited or no evidence to support the consumption of antioxidants or (super)foods rich in antioxidants, for the intended purpose of an antioxi...

A fresh perspective on hydrogen peroxide metabolism during exercise.

In vivo (normoxic), muscle contractions typically cause only minimal increases in H₂O₂ (<10%), whereas in vitro (hyperoxic) assays often show far greater increases (~150–340%).

If the journals are going to send your manuscript to chatbots to "review" it, you might as well prompt the bots to do the right thing by you, eh?

Happy to share our review paper, "Emerging Trends for the Regulation of Thiol-Based RedoxTranscription Factor Pathways" doi.org/10.1021/acs.... It was fun learning about the really cool science being undertaken by some excellent labs. Thanks, ACS Biochemistry, for the invite.
Emerging Trends for the Regulation of Thiol-Based Redox Transcription Factor Pathways
Thiol-based redox transcription factor pathways play central roles in the cellular response to peroxide stress. We review the bacterial OxyR, yeast AP-1 and mammalian NRF2/Keap1 systems and the princi...

So, how many genetic diseases come down to good ol’ loss-of-function in the targeted protein?

Your estimate is probably too high:
