Orderly programmed cell death
WebCell death was once believed to be the result of one of two distinct processes, apoptosis (also known as programmed cell death) or necrosis (uncontrolled cell death); in recent years, however, several other forms of cell death have been discovered highlighting that a cell can die via a number of differing pathways. Apoptosis is characterised by ... WebIn order to survive and multiply, cancer cells evade such death signaling mechanisms. Thus autophagy is a fundamental metabolic process with major implications in human health. Unlike narcosis, both autophagy and apoptosis stimulate programmed cell death without inducing inflammation.
