Overview

PPARGC1A is a transcriptional coactivator that regulates and interacts with genes involved in energy metabolism. It has a role in regulating metabolism, inflammation, oxidative stress resistance and mitochondrial biogenesis and function. SIRT1 has been reported to be a functional regulator of PPARGC1A. In mice, knockout of PPARGC1A accelerates vascular aging and atherosclerosis, coinciding with telomere dysfunction and shortening and DNA damage. Expression of PPARGC1A coactivates TERT transcription and reverses telomere malfunction. In humans, PPARGC1A has been associated with cholesterol and obesity as well as age-related diseases like type 2 diabetes. Thus, PPARGC1A may play a role in in ameliorating senescence, aging, and age-associated chronic diseases.
