Self-cannibalism is a type of body modification. Bodily functions self-cannibalize by consuming dead cells, as well as to break down complex substances into simple ones. Commonplace in the digestive system are self-cannibalistic processes, to name a few are metabolism, catabolism, and anabolism.

Cell cycle regulationEdit

Cyclins are a group of proteins that activate kinases involved in cell division. The degradation of cyclins is the key step that governs the exit from mitosis and progress into the next cell cycle.[1] Cyclins accumulate in the course the cell cycle, then abruptly disappear just before the anaphase of mitosis. The cyclins are removed via a ubiquitin-mediated proteolytic pathway.
