Recently, the epigenetic modifications have been recognized as a regulator of gene expression in various cancers. EZH2 gene is one the most important component of the PRC2 complex. Overexpression of EZH2 was identified in multiple cancers that considered more attractive the EZH2 role as an oncogene. Some studies report that EZH2 contributes to various aspects of colorectal cancer (CRC). However...

ZNF667/Mipu1, a C2H2-type zinc finger transcription factor, was suggested to play an important role in oxidative stress. However, none of the target genes or potential roles of ZNF667 in cardiomyocytes have been elucidated. Here, we investigated the functional role of ZNF667 in H9c2 cell lines focusing on its molecular mechanism by which it protects the cells from apoptosis. We found that ZNF66...

The tumor suppressor p53 is the most commonly mutated gene in human cancers. Active p53 is able to stimulate the transcription of a variety of genes including the pro-apoptotic gene bax, as well as p21, a cell cycle regulator. In this study we produced novel zinc finger transcription factors that would selectively increase the expression of bax, but not of other p53 targets. Reporter gene assay...

BACKGROUND Bax expression is a prerequisite for retinal ganglion cell (RGC) apoptosis. Experimental studies have reported Bax protein upregulation following optic nerve transection. The stimuli that trigger apoptosis share a common executioner proteolysis cascade, including caspase-3 and poly-(adenosine diphosphate ribose) polymerase cleavage. This study sought to elucidate the role of the mito...

The tumor suppressor gene p53 has been implicated in the loss of neuronal viability, but the signaling events associated with p53-mediated cell death in cortical and hippocampal neurons are not understood. Previous work has shown that adenovirus-mediated delivery of the p53 gene causes cortical and hippocampal neuronal cell death with some features typical of apoptosis. In the present study we ...

introduction: although the initial hypothesis for the action of doxepin was based on the inhibition of the reuptake of neurotransmitters, it has been suggested that it may also involve other mechanisms. therefore, this study aims to investigate the effect of doxepin on spatial memory, tumor necrosis factor alpha (tnf-α) level, expression of pro-apoptotic (bad and bax) and anti-apoptotic (bcl-2)...

An association of increased apoptosis with overexpression of the proapoptotic protein Bax-alpha has been reported in the left ventricle of adult spontaneously hypertensive rats (SHR). Both alterations were corrected in SHR that received long-term treatment with the AT1 antagonist losartan. To gain insight into the regulation of cardiac Bax-alpha protein in genetic hypertension, we investigated ...

Background and Objectives: Apoptosis plays a key role in pathogenesis of various cardiovascular diseases due to loss of terminally differentiated cardiac myocytes. Therefore, the aim of this study was to investigate effects of combined dietary restriction and aerobic training on indices of myocardial apoptosis in male rats. Materials and Methods: In this study, 32 three-month-old male rats wer...

Background: Recent studies have revealed that oocyte competence can be assessed through the presence of the glucose-6-phosphate dehydrogenase (G6PDH) enzyme, as indicated by brilliant cresyl blue (BCB), a dye that can be degraded by G6PDH. In the present study, we aimed to examine the validity of BCB test to select developmentally competent oocyte in ovine and its association with stage-specifi...
