The Claim

Inhibition of mTOR signaling extends lifespan in mammalian species, demonstrating that the TOR pathway plays a role in regulating mammalian longevity.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

18score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Scientists discovered that blocking a specific cell signaling pathway called mTOR can help mammals live longer. This finding shows that the TOR pathway is involved in controlling how long mammals live.

See the scientific wording

This study provides the first evidence in a mammalian species that inhibition of mTOR signaling can extend lifespan, establishing a role for the TOR pathway in the regulation of mammalian longevity.

What the research says

1 study

  1. Study: Rapamycin fed late in life extends lifespan in genetically heterogeneous mice

    The study gave mice a drug called rapamycin that blocks mTOR signaling, and this made the mice live longer. This was the first time anyone showed that blocking mTOR can extend lifespan in a mammal, which proves the claim is true.
