caspases

(kas'pās-ĕz),
Proteolytic cleavage products of the protein's procaspases that are responsible for cleaving and activation of additional procaspases into more caspases, thus resulting in a cascade of proteolytic activity the final result of which is apoptosis of the cell.
[cysteinyl aspartate specific proteinase]

caspases

A family of proteases, some of which are involved in APOPTOSIS.

(California, USA) were used consisting of [beta]-Actin (1:1000), Bax (1:1000), Bcl2 (1:1000), Hsp70 (1:1000), survivin (1:1000), caspase 3 (1:1000) and caspase 9 (1:1000).
Furthermore, necroptosis may represent an alternative form of death which can substitute apoptosis when caspase activation is blocked.
Amer explains that these findings represent a paradigm shift in caspase research.

Ellerby said the caspase inhibitors both suppressed the proteolysis of Htt and rescued HD neurons that have begun to undergo cell death.
Over expression or mutation of any proteins involved in the pathway leads to the inactivation of caspases. Inactivation of upstream pathway disrupts the activation of caspase-3 and leads to uncontrolled growth of cells.
Double-stranded RNA (dsRNA) was synthesized for both the caspase, acasp, and [beta] actin from Aiptasia pallida.

Her group thus evaluated a caspase activity blood test in 44 consecutive patients with suspected NAFLD.
Binding of Fas ligand (FasL) to Fas results in caspase 8 activation, which in turn activates and cleaves B cell chronic lymphocytic leukemia/lymphoma 2 (Bcl-2) interacting domain (Bid), a member of the Bcl-2 family.
Seemingly aware of the danger they themselves pose, these abnormal cells often try to commit suicide by activating destructive enzymes called caspases. But as if simultaneously compelled by a self-preservation instinct, tumor cells usually thwart this impulse using proteins that foil the caspases.
