Nutrient deprivation (e.g., amino acid starvation) triggers the perinuclear clustering of lysosomes 7 , the acidification of the lysosome lumen 15 , and concomitant elevation of lysosomal proteolysis, as well as the dissociation of mTORC1 from the lysosome surface 5 , resulting in the repression of mTORC1 signaling 16
This oxidative stress further impairs insulin receptor substrate signaling through serine phosphorylation, thereby deepening insulin resistance and perpetuating the metabolic disturbances characteristic of PCOS [80,81]
