Structural Basis for the Inhibition of Caspase-3 by XIAP

The molecular mechanism(s) that regulate apoptosis by caspase inhibition remain poorly understood. The main endogenous inhibitors are members of the IAP family and are exemplified by XIAP, which regulates the initiator caspase-9, and the executioner caspases-3 and -7. We report the crystal structure of the second BIR domain of XIAP (BIR2) in complex with caspase-3, at a resolution of 2.7 A, rev...

Bcl-2 overexpression attenuates resveratrol-induced apoptosis in U937 cells by inhibition of caspase-3 activity.

Resveratrol has been shown to induce anti-proliferation and apoptosis of human cancer cell lines. In the present study, we determined the effect of high intracellular levels of the anti-apoptosis protein Bcl-2 on caspase-3 activation, PLC-gamma1 degradation and cytochrome c release during resveratrol-induced apoptosis. For this, we used U937/vector and U937/Bcl-2 cells, which were generated by ...

Effect reversible inhibition of hippocampal CA1 rehion by lidocaine on amygdala kindling rata in rats

In this study the role of CA1 region of dorsal hippocamus an amygdala kindling rate was investigated by bilateral microinjection of lidocaine into hippocampus.28 rats were divided into four groups.in group I:animals were implanted only with a tripolar electrode into the amygdala but in groups 2-4,two guide cannulaae were also implanted into  the CA1 region of the dorsale hippocampus.two monopol...

Modifying Caspase-3 Activity by Altering Allosteric Networks

Caspases have several allosteric sites that bind small molecules or peptides. Allosteric regulators are known to affect caspase enzyme activity, in general, by facilitating large conformational changes that convert the active enzyme to a zymogen-like form in which the substrate-binding pocket is disordered. Mutations in presumed allosteric networks also decrease activity, although large structu...

Inhibition of distant caspase homologues by natural caspase inhibitors.

Caspases play an important role in the ability of animal cells to kill themselves by apoptosis. Caspase activity is regulated in vivo by members of three distinct protease inhibitor families, two of which, baculovirus p35 and members of the inhibitor of apoptosis (IAP) family, are thought to be caspase specific. However, caspases are members of the clan of cysteine proteases designated CD, whic...
