What Is Cellular Autophagy?

Good Essays

What is cellular autophagy? That is a question with a complex and not yet fully understood answer. The word autophagy is derived from the Greek words auto- and phagy- meaning self-eating. So cellular autophagy is a cell eating itself, also known as Autophagocytosis. Autophagy is a normal physiological process in which cells destroy organelles that are dysfunctional or no longer useful. This paper will cover the processes of autophagy, the function it has in the cell, the significance the process has to cellular homeostasis, and lastly; the how it affects cancer.
The Process of Autophagy
There are three defined forms of autophagy, Macro-autophagy, micro-autophagy, and chaperone-mediated autophagy; each form has its own way of carrying out autophagocytosis. Macro-autophagy delivers cargo to the Lysosome through a membrane-bound vesicle, also known as an autophagosome. The lysosome then carries out autolysosome to destroy the cargo. In micro-autophagy the cargo is taken directly taken up by the Lysosome instead of a vesicle bringing the cargo to it. Both Macro and Micro are capable of consuming large structures. In Chpaerone-mediated autophagy targeted proteins are carried across the lysosome membrane with chaperone proteins that result in their unfolding and degradation.
Autophagy in cells begin with an isolation membrane known as the phagophore. The phagophore is made up of a bilipid layer that is contributed to by the Endoplasmic Reticulum, although the origin of the
