Proapoptotic BAX and BAK control multiple initiator caspases.
BAX and BAK operate at both the mitochondria and endoplasmic reticulum (ER) to regulate the intrinsic apoptotic pathway. An unresolved issue is whether any caspases can be activated in response to intrinsic apoptotic signals in the absence of BAX and BAK. Following organelle-specific intrinsic stress signals, including DNA damage and ER stress, we detected no activation of CARD-containing caspa...
متن کاملProapoptotic bcl-2 family members, Bax and Bak, are essential for developmental photoreceptor apoptosis.
PURPOSE Apoptosis has been implicated in retinal development and degeneration, but the specific apoptotic pathways used are incompletely understood. The purpose of this study was to characterize the roles in retinal development of the proapoptotic Bcl-2 family members Bax and Bak. METHODS Eyes from mice at postnatal day (P)7, during the peak of developmental apoptosis in the retina, were proc...
متن کاملThe proapoptotic activities of Bax and Bak limit the size of the neural stem cell pool.
The proapoptotic Bcl-2 family members Bak and Bax play central and redundant roles in the regulation of apoptosis. In this study, we investigated the effect of loss of Bax and Bak in the CNS. The adult bax-/-bak-/- mice display masses of densely staining cells in the proliferative zones of the brain. These cells are shown to be a mix of neural progenitor cells and postmitotic cells at different...
متن کاملProapoptotic Bak and Bax guard against fatal systemic and organ-specific autoimmune disease.
Dysregulation of the "intrinsic" apoptotic pathway is associated with the development of cancer and autoimmune disease. Bak and Bax are two proapoptotic members of the Bcl-2 protein family with overlapping, essential roles in the intrinsic apoptotic pathway. Their activity is critical for the control of cell survival during lymphocyte development and homeostasis, best demonstrated by defects in...
متن کاملBAX and BAK proteins are required for cyclin-dependent kinase inhibitory drugs to cause apoptosis.
In previous reports, we have shown in SH-SY5 cells that olomoucine and roscovitine, two inhibitory drugs of cyclin-dependent kinases, caused apoptosis independent of the extrinsic pathway. In this experimental paradigm, apoptosis was refractory to the protective effects of either Bcl-2 or Bcl-XL overexpression. We are now reporting that the failure of Bcl-XL to prevent dell death was consistent...
