Multiwall carbon nanotubes (MWCNTs) have many attractive properties with potential applications in various fields. Despite their usefulness, however, the associated waste can be hazardous to the environment. To examine adverse effects in aquatic environments, Oryzias latipes were exposed to MWCNTs dispersed in water for 14 days and apoptosis and antioxidant gene expression were observed. This w...
Although several lines of evidence link muscle-derived oxidants and inflammation to skeletal muscle wasting via regulation of apoptosis and proteolysis, little information is currently available on muscle repair. The present work was designed to study oxidative stress response, inflammatory cytokines, apoptotic, or proteolytic pathways during the early (1 and 5 days) and later (14 days) stages ...
Many pro-apoptotic signals trigger mitochondrial cytochrome c release, leading to caspase activation and ultimate cellular breakdown. Cell survival pathways, including the mitogen-activated protein kinase (MAPK) cascade, promote cell viability by impeding mitochondrial cytochrome c release and by inhibiting subsequent caspase activation. Here, we describe a mechanism for the inhibition of cytoc...
Rsk-mediated phosphorylation and 14-3-3e binding of Apaf-1 suppresses cytochrome c-induced apoptosis

BACKGROUND Acute brain injury is an important health problem. Given the critical position of caspase 8 at the crossroads of cell death pathways, we generated a new viable mouse line (Ncasp8(-/-)), in which the gene encoding caspase 8 was selectively deleted in neurons by cre-lox system. METHODOLOGY/PRINCIPAL FINDINGS Caspase 8 deletion reduced rates of neuronal cell death in primary neuronal ...
It has been shown that chronic exposure to cypermethrin (CPM), a pyrethroid pesticide, results in follicular atresia via pathologically affecting angiogenesis, disrupting endocrine potential and enhancing oxidative stress. This study was aimed to uncover the CPM-exposed energy dependent follicular cells apoptosis and to estimate protective effect of vitamin E (VitE) as a potent antioxidant. Thi...
The regulation of cell death has been investigated in a number of clinical disorders including renal ischemic and toxic acute renal failure. Caspases play a crucial role in the execution or final phase of cell death by cleaving and inactivating various structural and functional intracellular proteins that are essential for cell survival and proliferation. Evidence is now emerging to implicate t...
salvia chorassanica bunge is one of the iranian endemic species of salvia. there is not any reported literature on s. chorassanica. this study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of s. chorassanica and its fractions on hela cell line. cells were cultured in ex-cell®, an animal free medium specially designed for hela cell line ...
caspase-3, one of the dominant effectors caspases, is activated in almost every model of apoptosis with various signaling pathways. hence, inhibition of caspase-3 has become an attractive target in the treatment of neurodegenerative diseases. caspase-3 inhibitory activities of some 1,2-benzisothiazol-3-one derivatives were modeled by quantitative structure–activity relationship (qsar) using ste...
