Cell death plays an important role in a number of physiological processes in all complex multicellular organisms. One of the molecules that regulates this process is BAX, an integral membrane protein, that promotes apoptosis. The function of BAX is countered by BCL-2 and BCL-XL. The differential expression of these proteins can influence the ability of the cell to die or survive. In this paper,...
The inability to undergo apoptosis is a crucial mechanism of multidrug resistance in acute myeloid leukemia (AML), and the analysis of mitochondrial apoptotic proteins may represent a significant prognostic tool to predict outcome. Bcl-2 and Bax oncoproteins were evaluated in 255 de novo AML patients (pts) by flow cytometry using an anti–bcl-2 monoclonal antibody (MoAb) and an anti-bax MoAb. Th...
Reports that apoptosis within populations of neurotrophin-dependent neurones is virtually eliminated in BAX-deficient mice and that BAX-deficient neurones survive indefinitely in culture without neurotrophins have led to the view that BAX is required for the death of neurotrophin-deprived neurones. To further examine this assertion in vivo, we have studied two populations of NGF-dependent neuro...
Methamphetamine is an illicit drug that is often abused and can cause neuropsychiatric and neurotoxic damage. Repeated administration of psychostimulants such as methamphetamine induces a behavioral sensitization. According to a previous study, Bax was involved in neurotoxicity by methamphetamine, but the function of Bax in rewarding effect has not yet been elucidated. Therefore, we have studie...
introduction: ghrelin is an endogenous peptide that has diverse functions in the body. one of the newly recognized roles of this peptide is its antiapoptotic effect. however, this function has not been investigated in normobaric hypoxia- induced apoptosis in body organs. this study will examine the effect of ghrelin treatment on bax-bcl-2 gene expression in the kidney of chronic hypoxic rats. m...
Introduction: Memory impairment is one of the complications of diabetes which may accompany with changes in expression of apoptotic and antiapoptotic genes. The aim of the present study was the evaluation of intra-hippocampal injection of aminoguanidine (AG), as an antioxidant and inducible nitric oxide synthase inhibitor, on passive avoidance memory and Bcl-2 family genes expression in diab...
Background and purpose: One of the main issues in cancer treatment is to reduce the side effects of drugs on healthy tissues. The aim of this study was to investigate the preventative effects of continuous aerobic exercise on apoptosis ratio and liver fibrosis induced by doxorubicin in aging rats. Materials and methods: In this experimental research, 42 adult Wistar rats were randomly divided ...
OPC (oligodendrocyte progenitor cell) death contributes significantly to the pathology and functional deficits following hypoxic-ischemic injury in the immature brain and to deficits resulting from demyelinating diseases, trauma and degenerative disorders in the adult CNS. Glutamate toxicity is a major cause of oligodendroglial death in diverse CNS disorders, and previous studies have demonstra...
