Aging differentially affects the uptake of methionine by select rat tissues.
Abstract
Experimental and epidemiological studies indicate that significant reductions in dietary methionine intake profoundly impact both health and life spans. Methionine levels also decrease in the blood of mammals as they age. Here, we report that methionine uptake by four of the major methionine-consuming organs, the liver, kidneys, heart, and brain, is increased in old rats as compared to young adult rats, as measured by [

Research summary
The paper claims that aging increases methionine uptake in key organs of rats. This research is relevant as it explores the metabolic changes associated with aging and their potential implications for health and lifespan, addressing a fundamental aspect of aging biology.
