The bcl-2 family of proteins.
The bcl-2 family of proteins play an important role in the control of apoptosis. Family members exist which are either pro- or anti-apoptotic and their activity appears to control a checkpoint between signals from the cell surface and activation of the ICE-family of proteases. Despite having a key role to play in apoptosis, the mechanism of action of these proteins can only, at present, be infe...
متن کاملEstrogen modulates Bcl-2 family proteins in ischemic brain injury.
Estradiol acts as a neuroprotective factor against brain injury. This study investigated whether estradiol modulates the Bcl-2 family proteins in ischemic brain injury. Adult female rats were ovariectomized and treated with estradiol prior to middle cerebral artery occlusion (MCAO). Brains were collected 24 hr after MCAO, and infarct volumes were analyzed. Estradiol significantly reduces the in...
متن کاملNew dimension in therapeutic targeting of BCL-2 family proteins
Proteins of the BCL-2 family control the mitochondrial pathway of apoptosis. Targeting these proteins proves to be an attractive strategy for anticancer therapy. The biological context is based on the fact that BH3-only members of the family are specific antagonists of prosurvival members. This prompted the identification of "BH3 mimetic" compounds. These small peptides or organic molecules ind...
متن کامل[The role of bcl-2 family proteins in psoriasis].
Apoptosis is a physiological process of programmed cell death responsible for homeostasis in the body. In skin, apoptotic process regulates keratinocyte proliferation and differentiation in that way maintaining homeostasis of epidermal compartment. The process of apoptosis is controlled by proteins of the Bcl-2 family, several proapoptotic (Bax, Bak, Bad) and antiapoptotic (Bcl-2, Bcl-x(L)) pro...
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...
