Livin, also called melanoma inhibitor of apoptosis protein (IAP) or kidney IAP, is a member of the IAP family of caspase inhibitors that selectively binds the endogenous IAP antagonist SMAC and caspase-3, caspase-7, and caspase-9. As such, Livin inhibits apoptosis, and its overexpression renders malignant cells resistant to chemotherapy. Therefore, inhibitors of Livin could be useful adjuncts t...

STUDY DESIGN Western blotting and flow cytometric analyses were performed using rat notochordal cells. OBJECTIVE To demonstrate the apoptotic effect of oxidative stress and the antiapoptotic effects of caspase inhibitors on rat notochordal cells. SUMMARY OF BACKGROUND DATA Although oxidative stress causes apoptosis in many cell types, its effect on the apoptosis of notochordal cell and anti...

Pyroptosis is a type of acute cell death that mainly occurs in immune cells. It characterized with robust release inflammatory cytokines and has emerged to play critical role the pathogenesis sepsis-associated disorders. In this study, we screened for pyroptotic inhibitors ultimate goal benefit sepsis treatments. Accidentally, identified nitrosonisoldipine (NTS), photodegradation product calciu...

cladribine acts as an antineoplastic, immunosuppressive and anti-inflammatory agent. the aim of this study was to examine the possible impact of this drug on the epidermis of wistar rats. the control group received standard feed and water. the experimental group i was treated with cladribine in a schema corresponding to the treatment of multiple sclerosis in humans. the material for microscopic...

Histone deacetylase (HDAC) inhibitors can induce programmed cell death in cancer cells, although the underlying mechanism is obscure. In this study, we show that two distinct HDAC inhibitors, butyrate and suberoylanilide hydroxamic acid (SAHA), induced caspase-3 activation and cell death in multiple human cancer cell lines. The activation of caspase-3 was via the mitochondria/cytochrome c-media...

There is increasing evidence that a variety of natural substances derived from the diet may act as potent chemopreventive agents. In this work, we show that DAOY cells, a widely used model of metastatic medulloblastoma (MBL), are highly sensitive to sulforaphane, a naturally occurring isothiocyanate from Brassica vegetables. Sulforaphane induced DAOY cell death by apoptosis, as determined by DN...

Caspases have been suggested to contribute to not only apoptosis regulation but also non-apoptotic cellular phenomena. Recently, we have reported the involvement of caspase-7 to the cell cycle progression at mitotic phase by knockdown of caspase-7 using small interfering RNAs and short hairpin RNA. Here we showed that chemically synthesized broad-spectrum caspase inhibitors, which have been use...
