摘要
SIRT7 with coenzyme NAD catalyzes protein de-acetylation. In stress response, SIRT7 regulates protein folding in mitochondria with unknown mechanisms. Decreases in SIRT7 entrain hematopoietic stem cell senescence, but increasing SIRT7 causes elevation of hematopoietic stem cell regenerative function. We discuss the recent findings on SIRT7 and its binding proteins, NRF1 and GABP1, in decision making between the choices of inducing cell aging and immortality.
