Introduction: Cardiomyocytes apoptosis contributes to the development of left ventricular hypertrophy. The Bcl-2 family members are important regulators of mitochondrial pathway of apoptosis. Monoterpenoid phenol –carvacrol– possesses strong antioxidant properties. The present study aimed to evaluate the effect of carvacrol on transcription level of pro-apoptotic (Bad and Bax) and...
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)...
Introduction: One of the complications of diabetes mellitus is induction of apoptosis in liver tissues. Activation of caspase 3 caused apoptosis in the cells. Garlic is a most common plant in diet that its effect on apoptosis was not determined. In this study the effects of this extract on Bax and Bcl-2 gene expression and the activity of caspase 3, were determined in type 1 and 2 of diabetes i...
The objective of this study was to evaluate the apoptotic effects of increasing granulosa cell density and increasing estradiol on relative gene expression associated with apoptosis factors (Bcl-2, Bax and GADD45β) and cell cycle (CCDN-2). For this reason after collecting ovaries of cows from an abattoir, granulosa cells were separated from 4- to 8-mm follicles. Then, viable cells were counted ...
Extensive experimental evidence suggests that Bcl-2 promotes cell survival by preventing the onset of apoptosis induced by a variety of stimuli. In addition, Bcl-2 expression has been correlated with resistance and poor response to chemotherapy in a number of cell types. Therefore, this protein represents a logical target for gene therapy strategies designed to achieve selective gene product ab...
To explore the effect of suppressing BCL-2 expression using RNA interference (RNAi) technique in nasopharyngeal carcinoma cell line CNE1. CNE1 cell lines stably expressing shRNAs targeted bcl-2 and GL3 gene were established and gene expression inhibition was assessed by Western blotting analysis. The effect of suppressing bcl-2 by RNAi on cell growth was studied, the apoptosis induction and the...
The organization and expression of the BCL-6 gene in normal and neoplastic thymic T cells has not been fully determined. We examined 8 precursor T-cell lymphoblastic lymphomas (T-LBLs) and found significant BCL-6 expression in 4 cases. Three of the BCL-6(+) cases expressed a common thymocyte phenotype (CD4(+), CD8(+)), and one expressed a precursor thymocyte phenotype (CD4(-), CD8(-)). In 6 cas...
Helicobacter pylori induces activation of mitogen-activated protein kinases (MAPKs). However, its effect on H. pylori-induced apoptosis has not been evaluated. Thus, we examined whether H. pylori-induced extracellular signal-regulated kinase 1 and 2 (ERK1/2) and p38 MAPK activation affects gastric epithelial cell apoptosis and bcl-2 family gene expression, especially in relation to the cagA sta...
It has been shown that mesothelioma expresses the antiapoptotic protein BCL-XL, but not BCL-2, rendering bcl-xl gene expression a potential therapeutic target. Sodium butyrate (NaB) is a histone deacetylase inhibitor capable of alteration of bcl-2 family protein expression in other tumor types. Mesothelioma cell lines (REN, I-45) were exposed to NaB, and viability (colorimetric assay) and apopt...
