Induction of GDF15 as a myomitokine. Different (patho)physiological conditions resulting in increased muscle mitochondrial stress activate the integrated stress response (ISR) culminating in a CHOP-dependent induction of GDF15 expression which can, but does not necessarily, result in increased secretion and circulating GDF15 levels.
