Through direct interaction with the voltage-dependent anion channel (VDAC), proapoptotic Bcl-2 family members such as Bax and Bak induce apoptogenic mitochondrial cytochrome c release and membrane potential (Deltapsi) loss in isolated mitochondria. Using isolated mitochondria, we showed that Bid and Bik, BH3-only proteins from the Bcl-2 family, induced cytochrome c release but not Deltapsi loss...

Crocin, the main constituent of saffron (Crocus sativus L.), is a natural carotenoid which is known for its antioxidant activity. Liver as the organ that metabolizes many chemicals is one of the first position that is at risk of environmental pollutants. It is clear that compounds that exhibit antioxidant properties, scavenging of free radicals and inhibition of lipid peroxidation are expected ...

Multiple Sclerosis (MS) is a neurodegenerative and autoimmune disease that it’s molecular etiology and factors involving in its progression remains unknown. In this study for evaluation effect of mercuric on progression of MS we investigated the additive effect of mercuric sulfide on the brain mitochondrial dysfunction in experimental autoimmune encephalomyelitis (EAE) model of MS in C57BL/6 mi...

B-acute lymphoblastic leukemia (B-ALL) is the frequent pediatric malignity. Chemotherapy is the most practical approaches to deal with such malignancies. Microtubule-targeted agents are one of the most strategic drugs which formerly use in chemotherapy.Although,colchicine-binding anti-tubulin agents exhibited promising effects in clinical trials, their exact mechanism of action is not fully und...

Natural products isolated from plant sources are well known for their pharmacological potential in diversity of disease treatments such as inflammatory or cancer conditions. Mango (Mangifera indica L.) and Juglans regia are thought to be rich of functional phytochemicals. To elucidate the anticancer activity of Juglans regia (JR) and Mangifera indica L (MI) aqueous extract were investigated on ...

Myocardial ischemia/reperfusion (I/R) is associated with an extensive loss of myocardial cells. The apoptosis repressor with caspase recruitment domain (ARC) is a protein that is highly expressed in heart and skeletal muscle and has been demonstrated to protect the heart against I/R injury (Gustafsson, A. B., Sayen, M. R., Williams, S. D., Crow, M. T., and Gottlieb, R. A. (2002) Circulation 106...

Mitochondrial outer membrane permeabilization by proapoptotic Bcl-2 family proteins, such as Bax, plays a crucial role in apoptosis induction. However, whether this only causes the intracytosolic release of inducers of caspase-dependent death, such as cytochrome c, or also of caspase-independent death, such as apoptosis-inducing factor (AIF) remains unknown. Here, we show that on isolated mitoc...

Mitochondrial mechanisms, particularly the release of cytochrome c, play a role in the death of nerve and glial cells in cerebral ischemia. We have currently investigated whether BID, a proapoptotic molecule of the bcl-2 family and promoter of the release of cytochrome c is expressed in the brain, activated by cerebral ischemia in vivo, and contributes to ischemic cell death. We found BID in th...
