Necrosis can be induced by stimulating death receptors with tumor necrosis factor (TNF) or other agonists; however, the underlying mechanism differentiating necrosis from apoptosis is largely unknown. We identified the protein kinase receptor-interacting protein 3 (RIP3) as a molecular switch between TNF-induced apoptosis and necrosis in NIH 3T3 cells and(More)
Cell growth can be suppressed by stressful environments, but the role of stress pathways in this process is largely unknown. Here we show that a cascade of p38β mitogen-activated protein kinase (MAPK) and p38-regulated/activated kinase (PRAK) plays a role in energy-starvation-induced suppression of mammalian target of rapamycin (mTOR), and that energy(More)
