Concomitant loss of proapoptotic BH3-only Bcl-2 antagonists Bik and Bim arrests spermatogenesis.
The BH3-only proteins of the Bcl-2 family initiate apoptosis through the activation of Bax-like relatives. Loss of individual BH3-only proteins can lead either to no phenotype, as in mice lacking Bik, or to marked cell excess, as in the hematopoietic compartment of animals lacking Bim. To investigate whether functional redundancy with Bim might obscure a significant role for Bik, we generated m...
متن کاملProapoptotic BH3-only BCL-2 family protein BIM connects death signaling from epidermal growth factor receptor inhibition to the mitochondrion.
A subset of lung cancers expresses mutant forms of epidermal growth factor receptor (EGFR) that are constitutively activated. Cancers bearing activated EGFR can be effectively targeted with EGFR inhibitors such as erlotinib. However, the death-signaling pathways engaged after EGFR inhibition are poorly understood. Here, we show that death after inhibition of EGFR uses the mitochondrial, or intr...
متن کاملInduction of BIM, a Proapoptotic BH3-Only BCL-2 Family Member, Is Critical for Neuronal Apoptosis
Sympathetic neuronal death induced by nerve growth factor (NGF) deprivation requires the macromolecular synthesis-dependent translocation of BAX from the cytosol to mitochondria and its subsequent integration into the mitochondrial outer membrane, followed by BAX-mediated cytochrome c (cyt c) release. The gene products triggering this process remain unknown. Here, we report that BIM, a member o...
متن کاملBH3-only proapoptotic Bcl-2 family members Noxa and Puma mediate neural precursor cell death.
Neural precursor cells (NPCs) are highly sensitive to genotoxic injury, which triggers activation of the intrinsic mitochondria-dependent apoptotic pathway. This pathway is typically initiated by members of the BH3 (Bcl-2 homology 3)-only subgroup of the Bcl-2 (B-cell CLL/lymphoma 2) protein family, which are positioned upstream in the apoptotic pathway to respond to specific death stimuli. We ...
متن کاملBH3-only proteins - evolutionarily conserved proapoptotic Bcl-2 family members essential for initiating programmed cell death.
The BH3-only members of the Bcl-2 protein family are essential initiators of programmed cell death and are required for apoptosis induced by cytotoxic stimuli. These proteins have evolved to recognise distinct forms of cell stress. In response, they unleash the apoptotic cascade by inactivating the protective function of the pro-survival members of the Bcl-2 family and by activating the Bax/Bax...
