Homeostatic Functions of BCL-2 Proteins beyond Apoptosis
Since its introduction in 1930 by physiologist Walter Bradford Cannon, the concept of homeostasis remains the cardinal tenet of biologic regulation. Cells have evolved a highly integrated network of control mechanisms, including positive and negative feedback loops, to safeguard homeostasis in face of a wide range of stimuli. Such control mechanisms ultimately orchestrate cell death, division and repair in a manner concordant with cellular energy and ionic balance to achieve proper biologic fitness. The interdependence of these homeostatic pathways is also evidenced by shared control points that decode intra- and extracellular cues into defined effector responses.
