Minimum fasting length required for autophagy | Guido Kroemer

Parent Episode: Dr. Guido Kroemer on Autophagy, Caloric Restriction Mimetics, Fasting & Protein Acetylation

A key regulator of the process of autophagy is a drop in cellular levels of acetyl CoA, an end product of nutrient metabolism. As one would expect, fasting – the abstention from all nutrients – is a potent inducer of autophagy. This is especially true in mice, which begin to experience autophagy within a few days of fasting. However, critical metabolic differences between mice and humans make it difficult to extrapolate these findings to humans. In this clip, Dr. Guido Kroemer describes the current state of knowledge about the minimum amount of time required for fasting-induced autophagy in humans.
