multiple sclerosis (ms) is a chronic inflammatory demyelinating disease of the central nervous system that inflammation, demyelination, oligodendrocyte loss, gliosis, axonal injury and neurodegeneration are the main histopathological hallmarks of the disease. although ms was classically thought as a demyelinating disease, but axonal injury occurs commonly in acute inflammatory lesions. in ms mi...

PURPOSE Rituximab (chimeric anti-CD20) can reverse the cisplatin-resistant phenotype of AIDS-related non-Hodgkin's lymphoma cell lines and results in cisplatin-mediated apoptosis. The mechanism by which apoptosis is achieved by the combination treatment was examined. EXPERIMENTAL DESIGN The AIDS-related lymphoma (ARL) cell line 2F7 was treated with rituximab, cisplatin, and a combination of t...

Here, we present evidence for a specific role of the splicing-related factor TCERG1 in regulating apoptosis in live cells by modulating the alternative splicing of the apoptotic genes Bcl-x and Fas. We show that TCERG1 modulates Bcl-x alternative splicing during apoptosis and its activity in Bcl-x alternative splicing correlates with the induction of apoptosis, as determined by assessing dead c...

Our objective is to study the relationship between the regulatory proteins Bcl-2/Bax and mitochondria-mediated apoptosis during the differentiation of adipose-derived stromal cells (ADSCs) into neurons. Immunocytochemistry and western blotting showed that the cells weakly expressed neuron-specific enolase (NSE) in the non-induced group and expressed NSE more strongly in the groups induced for 1...

Activation of initiator and effector caspases, mitochondrial changes involving a reduction in its membrane potential and release of cytochrome c (cyt c) into the cytosol, are characteristic features of apoptosis. These changes are associated with cell acidification in some models of apoptosis. The hierarchical relationship between these events has, however, not been deciphered. We have shown th...

purpose : to investigate the effects of mtp-131 on trabeculum cells cultured under hydrostatic pressure methods : glaucomatous human trabecular meshwork (gtm3) cells were divided into three groups: the mtp-131 group, the hydrostatic group, and the normal group. the mtp-131 group was pretreated with 1 µm mtp-131, and the cells were then cultured under 80 mmhg pressure for 24 hours. the normal gr...

Apoptosis is an early event of liver damage in diabetes and oxidative stress has been linked to accelerate the apoptosis in hepatocytes. Therefore, the compounds that can scavenge ROS may confer regulatory effects on high-glucose induced apoptosis. In the present study, primary rat hepatocytes were exposed to high concentration (40 mM) of glucose. At this concentration decreased cell viability ...

A current paradigm proposes that mitochondrial damage is a critical determinant of NLRP3 inflammasome activation. Here, we genetically assess whether mitochondrial signalling represents a unified mechanism to explain how NLRP3 is activated by divergent stimuli. Neither co-deletion of the essential executioners of mitochondrial apoptosis BAK and BAX, nor removal of the mitochondrial permeability...

Cells apoptosis induced by intense heat stress is the prominent feature of heat-related illness. However, little is known about the biological effects of heat stress on cells apoptosis. Herein, we presented evidence that intense heat stress could induce early apoptosis of HUVEC cells through activating mitochondrial pathway with changes in mitochondrial membrane potential(ΔΨm), release of cytoc...

The application of pulsed electric fields (PEF) is emerging as a new technique for tumor therapy. Picosecond pulsed electric fields (psPEF) can be transferred to target deep tissue non-invasively and precisely, but the research of the biological effects of psPEF on cells is limited. Electric theory predicts that intense psPEF will target mitochond...
