Proapoptotic BID is required for myeloid homeostasis and tumor suppression.

A Role for Proapoptotic BID in the DNA-Damage Response

The BCL-2 family of apoptotic proteins encompasses key regulators proximal to irreversible cell damage. The BH3-only members of this family act as sentinels, interconnecting specific death signals to the core apoptotic pathway. Our previous data demonstrated a role for BH3-only BID in maintaining myeloid homeostasis and suppressing leukemogenesis. In the absence of Bid, mice accumulate chromoso...

Bid Regulates the Pathogenesis of Neurotropic Reovirus

Reovirus infection leads to apoptosis in both cultured cells and the murine central nervous system (CNS). NF-kappaB-driven transcription of proapoptotic cellular genes is required for the effector phase of the apoptotic response. Although both extrinsic death-receptor signaling pathways and intrinsic pathways involving mitochondrial injury are implicated in reovirus-induced apoptosis, mechanism...

Suppression and Cutaneous Apoptosis Bid in Ultraviolet-Induced Immune A Critical Role for the Proapoptotic Protein

Tumor necrosis factor-related apoptosis-inducing ligand alters mitochondrial membrane lipids.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to have selective antitumor activity. TRAIL induces ubiquitous pathways of cell death in which caspase activation is mediated either directly or via the release of apoptogenic factors from mitochondria; however, the precise components of the mitochondrial signaling pathway have not been well defined. Notably, mitocho...

Proapoptotic Bid is required for pulmonary fibrosis.

The molecular mechanisms of pulmonary fibrosis are poorly understood. Previous reports indicate that activation of TGF-beta1 is essential for the development of pulmonary fibrosis. Here, we report that the proapoptotic Bcl-2 family member Bid is required for the development of pulmonary fibrosis after the intratracheal instillation of bleomycin. Mice lacking Bid exhibited significantly less pul...
