Background: Vitrification of oocytes is a fast-freezing technique, which may affect the quality of the human oocyte, and consequently affects the embryo development, pregnancy and birth. The aim of the current study was to investigate the consequence of in-vitro vitrification on maturation status of immature human oocytes, additionally, expression levels of stress, and apoptosis related genes. ...

Zerumbone (ZER), a natural compound has been extracted from Zingiber zerumbet with known pharmacological activities. The aim was to determine the anti-human Burkitt’s lymphoma (Raji) cell effect of ZER. 3-(4,5-dimethylthiazol-2-yl)-2,5,-diphenyltetrazolium bromide (MTT) assay used cytotoxic while Annexin-V-fluorescein isothiocyanate/propidium iodide-PI flow cytometric assays apoptotic ZER on hu...

Mechanical stimulation is capable of affecting cell apoptosis. Several studies have shown that the Bcl-2 gene family, including and Bax gene, plays an important role in apoptosis, as proteins produced by can inhibit apoptosis while promote Understanding how mechanical alters expression apoptosis-related genes cardiomyocytes contribute to development ways cardiomyocyte necrosis. Intermediate myo...

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-&alpha) level, expression of pro-apoptotic (Bad and Bax) and anti-apoptotic (B...

Cell death is a nearly ubiquitous feature of the developing nervous system, and differential death in males and females contributes to several well studied sex differences in neuron number. Nonetheless, the functional importance of neuronal cell death has been subjected to few direct tests. Bax, a pro-apoptotic protein, is required for cell death in many neural regions. Deletion of the Bax gene...

Background: Atypical fibroxanthoma (AFX) histologically mimics high-grade sarcoma in the skin, although it follows a benign clinical course. AFX occurs in the sun-exposed skin ands for this reason, an association with ultraviolet light has long been suspected. Methods: Bax is a programmed cell death protein and belongs to the Bcl-2 family. The immunohistochemical expression of Bax was analyzed ...

Background and Aims: Cadmium is an important environmental pollutant and a potent toxicant to organisms. However, the toxicity of Cadmium and its influences on stomach is still unclear. We examined the effects of intraperitoneal injection of Cadmium on mRNA expression of Bcl-2 and Bax genes in rat stomach. Materials and Methods: Twenty eight male Wistar rats weighing 200 to 250 g were randomly...

Background: BCL-2 is the most important anti-apoptotic regulator and Bax is a pro-apoptotic protein. The status of these parameters or the ration of BCL-2 to BAX is important in malignant cell fate as well as normal cells. Methods: Sixty-two ALL patients and 62 healthy sex-and age-matched controls were studied. After genotyping, the promoter region of the BAX and BCL-2 genes by RFLP-PCR meth...

Bax promotes cell death by permeabilizing mitochondrial outer membranes by an unresolved mechanism. However, in cells lacking the gene c-myc, membrane permeabilization by Bax is blocked by changes in the mitochondria that prevent Bax oligomerization. Drug-treated c-myc null cells and cells expressing Myc were used to map the topology of Bax in membranes prior to and after mitochondrial permeabi...

Bax, a death-promoting member of the Bcl-2 family of proteins, triggered cell death when expressed in plants from a tobacco mosaic virus vector. Analysis of Bax deletion mutants demonstrated a requirement for the BH1 and BH3 domains in promoting rapid cell death, whereas deletion of the carboxyl-terminal transmembrane domain completely abolished the lethality of Bax in plants. The phenotype of ...
