The Claim

Rapamycin treatment reduces phosphorylation of ribosomal protein S6 (rpS6) in visceral white adipose tissue, indicating biochemical inhibition of the mTORC1 signaling pathway in vivo.

Source: Rapamycin fed late in life extends lifespan in genetically heterogeneous mice

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

How it works
1 study reviewed
In plain English

A drug called rapamycin can block a specific protein in fat tissue that controls cell growth, which scientists can measure to show the drug is working as intended.

See the scientific wording

Rapamycin treatment is associated with reduced phosphorylation of ribosomal protein S6 (rpS6) in visceral white adipose tissue, demonstrating biochemical inhibition of the mTORC1 signaling pathway in vivo.

What the research says

1 study

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

    The study tests the same drug (rapamycin) as the claim mentions, but it only looks at whether rapamycin helps mice live longer - not whether it blocks a specific protein signal in fat tissue. These are related but different questions.
