The Bcl-2 proteins Noxa and Bcl-xL co-ordinately regulate oxidative stress-induced apoptosis.
Because the detailed molecular mechanisms by which oxidative stress induces apoptosis are not completely known, we investigated how the complex Bcl-2 protein network might regulate oxidative stress-induced apoptosis. Using MEFs (mouse embryonic fibroblasts), we found that the endogenous anti-apoptotic Bcl-2 protein Bcl-xL prevented apoptosis initiated by H(2)O(2). The BH3 (Bcl-2 homology 3)-onl...
متن کاملBcl-2 and Bcl-XL Regulate Proinflammatory Caspase-1 Activation by Interaction with NALP1
Caspases are intracellular proteases that cleave substrates involved in apoptosis or inflammation. In C. elegans, a paradigm for caspase regulation exists in which caspase CED-3 is activated by nucleotide-binding protein CED-4, which is suppressed by Bcl-2-family protein CED-9. We have identified a mammalian analog of this caspase-regulatory system in the NLR-family protein NALP1, a nucleotide-...
متن کاملActivation of Ets-2 by oxidative stress induces Bcl-xL expression and accounts for glial survival in amyotrophic lateral sclerosis.
Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by selective degeneration of motor neurons and glial activation. Cell-specific transcriptional regulation induced by oxidative stress may contribute to the survival and activation of astrocytes in the face of motor neuron death. In the present study, we demonstrate an age-dependent increase in Bcl-xL a...

BACKGROUND Erythropoietin (Epo) is required for correct execution of the erythroid differentiation program. Erythropoiesis requires Bcl-X(L), a major late target of Epo-receptor signaling. Mice lacking Bcl-X(L) die around embryonic age E12.5, forming normal erythroid progenitors but lacking functional red cells. Recently, serum-free culture conditions for expansion of murine red cell progenitor...
