Dr. Rhonda Patrick answers audience questions on various health, nutrition, and science topics in this Q&A session.

“FOXO proteins regulate many genes responsible for autophagy and activate mechanisms in many different cell types, including those in the nervous system, heart, kidneys, and muscles. Learn more about autophagy in this overview article.”

“Learn more about sirtuins in this overview article. Autophagy activation Autophagy is an adaptive response mechanism that is activated upon cellular stress to remove unnecessary or dysfunctional cellular components as well as mobilize stored energy reserves.”

“Notably, they also had an 18 percent reduction in caloric intake, a potential confounder for their findings. Lastly, polyphenols in caffeinated or decaffeinated coffee induce autophagy in the liver, muscle, and heart in mice four hours after consumption.”

“It is a key player in the regulation of the aging process. Multiple studies demonstrate that SIRT1 mediates autophagy induction by interacting with components of the autophagy machinery such as FOXO1 and FOXO3a. Learn more about autophagy in this overview article.”

“In addition, factors involved in cellular housekeeping activities (such as autophagy) increased in the calorie-restricted group. Three multicenter pilot studies of caloric restriction have investigated the feasibility and outcomes of long-term calorie restriction in humans.”

“Evidence indicates that calorie restriction induces autophagy; however, adherence to the practice is challenging and often not sustainable. Autophagy is a highly conserved adaptive response to stress that involves the sequestration and subsequent destruction of protein aggregates, pathogens, and damaged or dysfunctional cellular components.”

“Q: Does green tea promote autophagy? A: Check out this clip of the FoundMyFitness podcast with Dr. Guido Kroemer reviewing the effects of another polyphenol-rich beverage, coffee, on autophagy. Q: Do polyphenols suppress the benefits of exercise?”

“However, a high LC3-II level or many autophagosomes can indicate either increased autophagy or a downstream blockade that prevents cargo degradation. Researchers therefore assess autophagic flux—the amount of material moving through the complete pathway—by comparing markers before and after lysosomal inhibition or by using reporters that distinguish autophagosomes from acidified autolysosomes.”

“Role and function of mTOR mTOR is a kinase—a type of enzyme—that participates in essential cellular pathways involved in growth, proliferation, motility, survival, protein synthesis, autophagy, and gene transcription.”
