Regulation of the Autophagic Bcl-2/Beclin 1 Interaction
Autophagy is an intracellular degradation process responsible for the delivery of cellular material to the lysosomes. One of the key mechanisms for control of autophagy is the modulation of the interaction between the autophagic protein Beclin 1 and the members of the anti-apoptotic Bcl-2 family (e.g., Bcl-2, Bcl-XL and Mcl-1). This binding is regulated by a variety of proteins and compounds th...
متن کاملBCL-2: pro-or anti-oxidant?
Bcl-2 is recognized as an oncoprotein via its ability to impede death signaling by sequestrating pro-apoptotic proteins such as Bax and Bak as well as preserving mitochondrial outer membrane integrity. Recently, a growing body of evidence has evaluated the role of Bcl-2 in intracellular redox regulation and its downstream effects on life and death decisions in cancer cells. On the backdrop of t...
متن کاملThe pan-Bcl-2 inhibitor (-)-gossypol triggers autophagic cell death in malignant glioma.
Antiapoptotic Bcl-2 family members suppress both apoptosis and autophagy and are of major importance for therapy resistance of malignant gliomas. To target these molecules, we used BH3 mimetics and analyzed the molecular mechanisms of cell death induced thereby. Glioma cells displayed only limited sensitivity to single-agent treatment with the BH3 mimetics HA14-1, BH3I-2', and ABT-737, whereas ...
متن کاملOxygen-Glucose-Deprivation/Reoxygenation-Induced Autophagic Cell Death Depends on JNK-Mediated Phosphorylation of Bcl-2.
BACKGROUND/AIMS The purpose of this study was to investigate the role of autophagy in oxygen-glucose-deprivation/reoxygenation (OGD/R) injury in rat neurons. METHODS AND RESULTS Cortical neurons were isolated from Sprague-Dawley rats and identified by immunofluorescence. The cortical neurons were randomly assigned to one of four groups: control group (I), experimental group (OGD/R group, II),...
متن کاملAnti-apoptotic Bcl-2 Family Proteins Disassemble Ceramide Channels.
Early in mitochondria-mediated apoptosis, the mitochondrial outer membrane becomes permeable to proteins that, when released into the cytosol, initiate the execution phase of apoptosis. Proteins in the Bcl-2 family regulate this permeabilization, but the molecular composition of the mitochondrial outer membrane pore is under debate. We reported previously that at physiologically relevant levels...
