in many models of programmed cell death, the mitochondrial protein aif translocates to the nucleus, where it induces the chromatin condensation and dna degradation. however, today it is well established that this flavoprotein is bifunctional. in addition to its lethal function in the nucleus of dying cells, aif plays a vital bioenergetic role in healthy ones by regulating mainly the activity of...

OBJECTIVE This research aimed to investigate whether glutamate induced spiral ganglion neurons (SGNs) apoptosis through apoptosis inducing factor (AIF) pathway. And verify whether PD150606, a calpain inhibitor could prevent apoptosis by inhibiting cleaving and releasing AIF in mitochondrion. METHODS SGNs of postnatal days 0-3 were harvested and cultured in dishes. 20 mM Glu, the caspase inhib...

Background and Purpose: Candida albicans is a prevalent human fungal pathogen that can cause a wide spectrum of diseases, from superficial mucosal infections to systemic disorders, in patients with impaired immunity. Glabridin is a pyranoisoflavan originally extracted from root extract of Glycyrrhiza glabra. Glabridin can also mediate apoptosis in yeast cells by changing the mitochondrial membr...

Apoptosis-inducing factor (AIF) plays a crucial role in caspase-independent programmed cell death by triggering chromatin condensation and DNA fragmentation. Therefore, it might be involved in cell homeostasis and tumor development. In this study, we report significant AIF downregulation in the majority of renal cell carcinomas (RCC). In a group of RCC specimens, 84% (43 out of 51) had AIF down...

Streptococcus pneumoniae is the major cause of bacterial meningitis and it damages the hippocampus by inducing neuronal apoptosis. The blocking of caspases provides only partial protection in experimental meningitis, which suggests that there is an additional apoptotic pathway. A trigger of this pathway is the bacterium itself, as exposure of microglia or neurons to live pneumococci induces rap...

AIM: This study analyzed the nephroprotective effect by examining apoptosis-inducing factor (AIF) expression and apoptosis rate in glomerular parietal epithelial cell of cisplatin-exposed rats. METHODS: Samples consisted 30 rats (divided into 3 groups: Group P0 received no treatment, group P1 a cisplatin injection on 7th day, P2 glutamine days 1–7 day). After 72 h, tissue samples were immunohis...

The Bcl-2 19 kDa interacting protein (BNIP3) is a pro-cell-death BH3-only member of the Bcl-2 family. We previously found that BNIP3 is localized to the nucleus in the majority of glioblastoma multiforme (GBM) tumors and fails to induce cell death. Herein, we have discovered that nuclear BNIP3 binds to the promoter of the apoptosis-inducing factor (AIF) gene and represses its expression. BNIP3 ...
