What is the definition of autophagy?
['autophagy, a process in which de novo formed membrane enclosed vesicles engulf and consume cellular components', 'As a general definition, autophagy encompasses a range of processes in which the cell degrades parts of itself within the lysosome (or the analogous organelle, the vacuole, in yeast and plants), followed by the release and reuse of the breakdown products', 'definition of autophagy is the following: all processes in which intracellular material is degraded within the lysosome/vacuole and where the macromolecular constituents are recycled', 'Autophagic PCD in animals is defined as being accompanied by an increase in the number of autophagosomes, autolysosomes, and small lytic vacuoles produced by autolysosomes', 'utophagy is the endogenous, tightly regulated cellular "housekeeping" process responsible for the degradation of damaged and dysfunctional cellular organelles and protein aggregates', 'utophagy has been predominantly studied as a nonselective self-digestion process that recycles macromolecules and produces energy in response to starvation', 'utophagy is a ubiquitous eukaryotic cytoplasmic quality and quantity control pathway', 'utophagy is a catabolic trafficking pathway for bulk destruction and turnover of long-lived proteins and organelles via regulated lysosomal degradation.', ' non-apoptotic programmed cell death, such as autophagy ', 'utophagy and senescence share a number of characteristics, which suggests that both responses could serve to collaterally protect the cell from the toxicity of external stress such as radiation and chemotherapy and internal forms of stress such as telomere shortening and oncogene activation']
['There are several definitions of autophagy. Among them, autophagy can be defined as a non- apoptotic programmed cell death that consists on a catabolic trafficking pathway for bulk destruction and turnover of long-lived proteins and organelles via regulated lysosomal degradation.']
