Vital functions of Apoptosis Inducing Factor (AIF)
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...

متن کاملGlabridin triggers over-expression of apoptosis inducing factor (AIF) gene in Candida albicans
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...
متن کاملApoptosis inducing factor (AIF) mediates lethal redox stress induced by menadione
Mitochondrial apoptosis inducing factor (AIF) is a redox-active enzyme that participates to the biogenesis/maintenance of complex I of the respiratory chain, yet also contributes to catabolic reactions in the context of regulated cell death when AIF translocates to the cytosol and to the nucleus. Here we explore the contribution of AIF to cell death induced by menadione (2-methyl-1,4-naphtoquin...
متن کاملExpression of cortical and hippocampal apoptosis-inducing factor (AIF) in aging and Alzheimer's disease.
Apoptosis-inducing factor (AIF) is a mitochondrial oxidoreductase originally identified for its role in caspase-independent programmed cell death (PCD). In this study, we investigated AIF protein expression levels in frontal and temporal cortices of normal subjects of various ages, as well as in subjects with Alzheimer's disease (AD). AIF levels were also measured in the hippocampus of age-matc...
