BCL-2 modifying factor (BMF) is a central regulator of anoikis in human intestinal epithelial cells.

ABSTRACT: BCL-2 modifying factor (BMF) is a sentinel considered to register damage at the cytoskeleton and to convey a death signal to B-cell lymphoma 2. B-cell lymphoma 2 is neutralized by BMF and thereby facilitates cytochrome C release from mitochondria. We investigated the role of BMF for intestinal epithelial cell (IEC) homeostasis. Acute colitis was induced in Bmf-deficient mice (Bmf(-/-)) with dextran sulfate sodium. Colonic crypt length in Bmf(-/-) mice was significantly increased as compared with WT mice. Dextran sulfate sodium induced less signs of colitis in Bmf(-/-) mice, as weight loss was reduced compared with the WT. Primary human IEC exhibited increased BMF in the extrusion zone. Quantitative PCR showed a significant up-regulation of BMF expression after initiation of anoikis in prim
