Caspase-9 swings both ways in the apoptosome [PDF]
For nearly 2 decades, investigators have debated whether cysteinyl-aspartate-specific protease 9 (caspase-9) is activated within the apoptotic protease-activating factor 1 (Apaf-1) apoptosome through proximity-induced homodimerization or through ...

Quantification of Immunostained Caspase-9 in Retinal Tissue. [PDF]
The family of caspases is known to mediate many cellular pathways beyond cell death, including cell differentiation, axonal pathfinding, and proliferation. Since the identification of the family of cell death proteases, there has been a search for tools to identify and expand the function of specific family members in development, health, and disease ...

Proteolytic Processing of the Caspase-9 Zymogen Is Required for Apoptosome-mediated Activation of Caspase-9 [PDF]
Maturation of the single-chain caspase-9 zymogen through autoproteolytic processing is mediated by the Apaf-1 apoptosome at the onset of apoptosis. Processed caspase-9 and the apoptosome form a holoenzyme with robust proteolytic activity that is 2-3 orders of magnitude higher than that of free processed caspase-9.

Astaxanthin effect on apoptotic biomarkers in methotrexate-induced liver injury
Methotrexate is used in the treatment of cancer, psoriasis, rheumatoid arthritis and several other disorders. It has a hepatotoxic potential side effect. Patients who have no access to alternative medications face a serious challenge as a result.

The Apoptosome Activates Caspase-9 by Dimerization [PDF]
The apical protease of the human intrinsic apoptotic pathway, caspase-9, is activated in a polymeric activation platform known as the apoptosome. The mechanism has been debated, and two contrasting hypotheses have been suggested. One of these postulates an allosteric activation of monomeric caspase-9; the other postulates a dimer-driven assembly at the

Apoptosis and autophagy: Regulation of caspase‐9 by phosphorylation [PDF]
Cell death by the process of apoptosis plays important roles in development, tissue homeostasis, diseases and drug responses. The cysteine aspartyl protease caspase‐9 plays a central role in the mitochondrial or intrinsic apoptotic pathway that is engaged in response to many apoptotic stimuli.

MDA-MB-231 cell apoptosis in vitro induced by dihydromyricetin
To investigate the effect of dihydromyricetin (DMY) induction on MDA-MB-231 cell apoptosis and its mechanism, the changes of cell morphological characteristics were observed under inverted microscope.

Regulation of the Apaf-1–caspase-9 apoptosome [PDF]
Apoptosis is probably not the only form of cell death, but it is currently the only form for which the proteins that constitute the death pathway have been characterized at the structural, biochemical and genetic levels in great detail.
