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

A mutation in caspase-9 decreases the expression of BAFFR and ICOS in patients with immunodeficiency and lymphoproliferation [PDF]
Lymphocyte apoptosis is mainly induced by either death receptor-dependent activation of caspase-8 or mitochondria-dependent activation of caspase-9. Mutations in caspase-8 lead to autoimmunity/lymphoproliferation and immunodeficiency. This work describes

A non-apoptotic role for caspase-9 in muscle differentiation [PDF]
Caspases, a family of cysteine proteases most often investigated for their roles in apoptosis, have also been demonstrated to have functions that are vital for the efficient execution of cell differentiation.

Heat-shock pretreatment inhibits sorbitol-induced apoptosis in K562, U937 and HeLa cells. [PDF]
The aim of this study was to determine whether heat-shock pretreatment exerted a protective effect against sorbitol-induced apoptotic cell death in K562, U937 and HeLa cell lines and whether such protection was associated with a decreased cytochrome c

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.

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.

Mechanism of XIAP-Mediated Inhibition of Caspase-9 [PDF]
The inhibitor of apoptosis (IAP) proteins potently inhibit the catalytic activity of caspases. While profound insight into the inhibition of the effector caspases has been gained in recent years, the mechanism of how the initiator caspase-9 is regulated by IAPs remains enigmatic.
