Caspase-3 has been found to be necessary for normal brain development as well as its typical role in apoptosis, where it is responsible for chromatin condensation and DNA fragmentation. [20] Elevated levels of a fragment of Caspase-3, p17, in the bloodstream is a sign of a recent myocardial infarction. [51]
Caspase-3 is activated in the apoptotic cell. [9] Caspase-3 activation is a cell requirement during early stages of the skeletal myoblast differentiation. Its catalytic site involves sulfohydryl group of Cys-285 and the imidazole ring of its His-237. The caspase-3 His-237 stabilizes the target Aspartate causing the break of the association of ...
Simple explanation of the mechanisms of apoptosis triggered by internal signals (bcl-2), along the caspase-9, caspase-3 and caspase-7 pathway; and by external signals (FAS and TNF), along the caspase 8 pathway.

During apoptosis, the apoptotic effector caspase, caspase-3, cleaves ICAD and thus causes CAD to become activated. [7] A nucleosome, consisting of DNA (grey) wrapped around a histone tetramer (coloured). In apoptotic DNA fragmentation, the DNA is cleaved in the internucleosomal linker region, which is the part of the DNA not wrapped around the ...

In cerebellar granule cells and cortical neurons, E2F1 can trigger neuronal apoptosis through activation of Bax/caspase-3 and the induction of the Cdk1/FOXO1/Bad pathway (Giovanni et al., 2000). The downregulation of p130/E2F4 (a complex which has been shown to maintain the post mitotic nature of neurons) induces neuronal apoptosis by ...
Apoptosis Inducing Factor (AIF) is a protein that triggers chromatin condensation and DNA fragmentation in a cell in order to induce programmed cell death. The mitochondrial AIF protein was found to be a caspase-independent death effector that can allow independent nuclei to undergo apoptotic changes. The process triggering apoptosis starts ...
Recently taurine has been found to prevent ischemia-induced apoptosis in cardiomyocytes through its ability to inhibit Apaf1/caspase-9 apoptosome formation without preventing mitochondrial dysfunction. The possible mechanism by which taurine inhibits the apoptosome formation was identified as being capable of reducing the expression of caspase ...
