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.
What the research says
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.
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.
