Bax and Bcl-2 are proteins that regulate programmed cell death and apoptosis. The expression of these proteins can be regulated, at least in part, by the tumor suppressor p53, but the effects of p53 are highly tissue specific. In an effort to better understand the relation between p53 and the in vivo control of the expression of Bax and Bcl-2 in adenocarcinomas of the breast, we evaluated by im...

It is known that the ovarian extract of Singkarak Lake Pufferfish (Tetraodon leiurus) has potential for chemoprevention in MCF-7 cells. However, expression Bcl-2 and Bax genes was associated with cancer. Therefore, this study aimed to analyze gene induced by MCF-7. The method an vitro experiment using control cells leiurus), Real-time PCR used examine genes. result showed had insignificant decr...

Malonate, an inhibitor of mitochondrial complex II, is a widely used toxin to study neurodegeneration in Huntington's disease and ischemic stroke. We have shown previously that malonate increased reactive oxygen species (ROS) production in human SH-SY5Y neuroblastoma cells, leading to oxidative stress, cytochrome c release, and apoptotic cell death. Expression of a green fluorescent protein-Bax...

We have previously shown that malonate increased reactive oxygen species (ROS) production in human SH-SY5Y neuroblastoma cells, leading to oxidative stress, cytochrome-c release, and apoptotic cell death.

Objective(s): Varicocele is an abnormal dilation in the testicular vein, which can cause hypoxia, reactive oxygen species accumulation, elevation in testicular temperature, and promote apoptosis and increase proinflammatory cytokine production. According to the varicocele pathophysiology, it is possible that a group of cytosolic receptors called nucleotide oligomerization domain (NOD)-like rece...

Increased apoptosis in crypt enterocytes is a key feature of intestinal adaptation following massive small bowel resection (SBR). Expression of the proapoptotic factor Bax has been shown to be required for resection-induced apoptosis. It has also been demonstrated that p38-α MAPK (p38) is necessary for Bax activation and apoptosis in vitro. The present studies were designed to test the hypothes...

Sympathetic neuronal death induced by nerve growth factor (NGF) deprivation requires the macromolecular synthesis-dependent translocation of BAX from the cytosol to mitochondria and its subsequent integration into the mitochondrial outer membrane, followed by BAX-mediated cytochrome c (cyt c) release. The gene products triggering this process remain unknown. Here, we report that BIM, a member o...

Ultraviolet irradiation resistance-associated gene (UVRAG) is a well-known regulator of autophagy by promoting autophagosome formation and maturation. However, little is known about the non-autophagic functions of UVRAG. Here, we present evidence that UVRAG functions as an unusual BCL2-associated X protein (Bax) suppressor to regulate apoptosis. Chemotherapy and radiation induces UVRAG expressi...

OBJECTIVE To define the long-term effects of GnRH antagonist, GnRH agonist, and estrogen plus progesterone treatments on apoptosis and apoptosis-related gene expressions, including bcl2, bax, and cyt c in rat ovary. DESIGN Prospective placebo-controlled experimental study. SETTING Obstetrics and Gynecology and Medical Biology and Genetics university departments. ANIMAL(S) Forty female wis...

The prodeath effects of p53 are typically mediated via its transcriptional upregulation of proapoptotic Bcl-2 family members, including PUMA, Noxa, and/or Bax. We previously reported that staurosporine (STS), a broad-spectrum kinase inhibitor and prototypical apoptosis-inducing agent, produced p53-dependent, Bax-dependent, neural precursor cell (NPC) apoptosis, but that this effect occurred ind...
