Abstract 4071: Sestrins modulate the expression of the metabolic stress sensor AMPK in breast cancer cells

Abstract Introduction: Sestrins (SESN) are stress response mediators that accumulate in cells exposed to genotoxic stresses, such as ultraviolet and ionizing radiation (IR). The three mammalian SESN (1-3) were recently shown to modulate signalling events. SESN1/2 are suggested to interact with and increasing the activity of the metabolic stress sensor AMP-activated protein kinase (AMPK). SESN1/2 have been postulated to act as …
