AI synopsis

What people are saying

Discussions reflect a balance of curiosity and critical analysis, with posts referencing the sex and dose dependency of rapamycin's effects, its metabolic distinctness from dietary restriction, and concerns about behavioral side effects; the tone ranges from scientific curiosity to cautious skepticism, illustrating both interest and engagement in understanding its broader implications.

AgreementModerate agreement

Most discussions acknowledge the findings, especially the dose and sex dependency of rapamycin's effects, showing moderate consensus.

InterestModerate interest

Participants demonstrate a moderate interest, discussing both the potential and limitations of rapamycin for lifespan extension.

EngagementModerate engagement

The exchanges include detailed comments on biological mechanisms and considerations, indicating engaged and thoughtful participation.

ImpactModerate impact

The conversations highlight the significance of these findings for future research, but some express skepticism about translating results to humans, indicating moderate perceived impact.

Abstract in brief

  • Rapamycin, an mTOR inhibitor, increases lifespan in mice in a way that depends on the dose and the sex of the mice, with females seeing a greater increase in longevity than males.
  • The way rapamycin extends lifespan is different from dietary restriction, as it causes unique metabolic and gene expression changes, especially in liver genes related to xenobiotic metabolism.
  • These findings suggest that rapamycin and dietary restriction extend lifespan through different mechanisms, with rapamycin's effects also showing potential differences based on sex.]

The longest documented lifespan extension by rapamycin was 26%; this was in mice. Unfortunately, there has been no study of rapamycin in the lifespan extension of humans and primates so far. https://t.co/CMTaLxuIZh

If you are a mouse, rapamycin can increase lifespan by 23% (males) to 26% (females) https://t.co/05toGQyGwO

@NataliaMitin @MattYousefzadeh In general, females (flies and mice) showed greater lifespan extension in responses to rapamycin, when it used chronically. Mice results - > e.g. ITP Rich Miller et al. https://t.co/7h65UU9lQh

@shunyata2000 Rapamycin • Fighting elevated in highest-dose-group ➡️high proportion of mice removed ➡️removal of up-to 22% of cages • More serious fight wounds • ➡️aggressive behavior and/or poor wound healing? • "Data" : Mice removed for fighting treated as alive https://t.co/bMmj5nOoDU

@Blagosklonny Very poss true- higher doses correl w/ both glucose & LE ( tho’ in man we may mitigate w/ other rx & optim. schedules). https://t.co/BSG1fxRGmv Since LE in man is unproven, w/o lifespan studies we need better efficacy & risk surrogates. Eg-quantif. relation b/n trough & ID risk
