Bax is a proapoptotic member of the Bcl-2 family of proteins. The Bax protein is dormant in the cytosol of normal cells and is activated upon induction of apoptosis. In apoptotic cells, Bax gets translocated to mitochondria, inserts into the outer membrane, oligomerizes and triggers the release of cytochrome c, possibly by channel formation. The BH3 domain-only protein Bid induces a conformatio...

The Bcl-2-related protein Bax is toxic when expressed either in yeast or in mammalian cells. Although the mechanism of this toxicity is unknown, it appears to be similar in both cell types and dependent on the localization of Bax to the outer mitochondrial membrane. To investigate the role of mitochondrial respiration in Bax-mediated toxicity, a series of yeast mutant strains was created, each ...

Apoptosis has been proposed to play an important role in the progression of renal scarring. The mechanisms that determine whether a cell enters the apoptotic program are complex. Bax and Bcl-2 are recognized modulators of this event; their relative levels determine the fate of cells. A role for apoptosis in the progression of renal scarring in the remnant kidneys of rats submitted to subtotal n...

background: simvastatin is a widely used medication in cardiac care. here we evaluate the role of atp sensitive potassium (katp) channels in simvastatin induced renal protection after renal ischemia/reperfusion (i/r) injury.    methods: a total of 81 male wistar rats, were treated with simvastatin (10 and 20mg/kg/day gavage, one week). some groups received glibenclamide (katp channel inhibitor ...

We recently isolated the AtBI-1 (Arabidopsis Bax Inhibitor-1) gene, the expression of which suppressed Bax-induced cell death in yeast. To determine whether the same is true in the plant system, transgenic Arabidopsis plants overexpressing Bax protein under a dexamethasone (DEX)-inducible promoter were generated. On DEX treatment, such transgenic plants exhibited marked cell death at the whole-...

Radiotherapy plays an important role in the treatment of hepatocellular carcinoma (HCC). Cyclin G1 is a novel member cyclin family, and it abnormally expressed HCC. In this study we investigated radiotherapy HCC cells. The expression was silenced by transfection G1-siRNA into HepG2 cells Huh7 cells, mRNA protein measured qRT-PCR Western blot analysis. proliferation analyzed using MTT assay, rad...

BCL-2-associated X protein (BAX) is a critical apoptotic regulator that can be transformed from a cytosolic monomer into a lethal mitochondrial oligomer, yet drug strategies to modulate it are underdeveloped due to longstanding difficulties in conducting screens on this aggregation-prone protein. Here, we overcame prior challenges and performed an NMR-based fragment screen of full-length human ...

Abstract FK506-binding protein 2 (FKBP13) is a part of the immunophilin family involved in immunoregulation. It also believed to operate as factor membrane cytoskeletal framework and an ER chaperone. FKBP2 FKBP1 (FKBP12), known immunophilins, are binding proteins for rapamycin FK506, which immunosuppressive drugs. was suggested that immunophilin-like play significant roles regulating intracellu...

Yiqi Yangyin complex (YYC), the homology of medicine and food, is comprised Polygonati Rhizoma, Lycii Fructus, Codonopsis Pilosula, Rehmanniae Radix. Herein, YYC polysaccharide treatment effectively attenuated progression MGH in a mice model-induced with estrogen progestogen. significantly relived hormonal disorders by reducing levels receptor α (ERα) progesterone (PR), substantially elevated p...
