Web10 feb. 2006 · We conclude that caspases 3 and 7 are critical mediators of mitochondrial events of apoptosis. Mitochondria play a central role in apoptosis. Mitochondrial outer membrane permeabilization (MOMP) leads to release of proapoptotic factors such as cytochrome c and AIF ( 1 ). WebThe activation of caspase enzymes occurs very early in the apoptotic process. These enzymes comprise a family of cysteine–aspartic acid specific proteases that have been identified as crucial mediators of the complex biochemical events associated with apoptosis. Also see the section below for antibodies and other tools to detect caspases. WebIn general, cultured cells induced to undergo apoptosis exhibit signs of apoptotic events much sooner (within hours; 5–10) than cells within tissues (within days; 11–14). When studying an in vivo model, some late apoptotic events may never be detected, as apoptotic cells in tissues are often phagocytosed before late events can be detected. impression dental group indooroopilly
