The Claim

In aged mice with hyperactive mTORC1 due to skeletal muscle-specific DEPDC5 knockout, rapamycin treatment is associated with significant alterations in skeletal muscle lipid composition, including increased levels of diacylglycerols (DG), cholesterol esters (CE), and lyso-phosphatidylethanolamines (LPE), and decreased levels of phosphatidylcholines (PC) and phosphatidylglycerols (PG), suggesting that mTORC1 inhibition reprograms lipid metabolism in aging skeletal muscle.

Supports is higher

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

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

In older mice with overactive muscle metabolism, giving them a drug called rapamycin changes the types of fats in their muscles — some go up, some go down — which might mean the drug helps reset how aging muscles handle fat.

  1. Study: Rapamycin Treatment Induces Lipidomic and Metabolic Changes in Skeletal Muscle of Aged Mice with Hyperactive mTORC1

    The study looked at old mice with overactive mTORC1 in their muscles and found that giving them rapamycin changed the types of fats in their muscle in the exact way the claim describes.
