CTCF:FirstMultivalentNuclearFactor
CTCF is central to signaling pathways in immature B cells elicited by cross-linking the Ig BCR and stimulation with TGF?. Both stimuli result in induction of cell cycle arrest and apoptosis. BCR ligation stimulates a transient induction of MYC that leads to high level CTCF expression and feedback suppression of MYC transcription. BCR ligation also activates PTEN opposing PI3K activation of MYC. Pharmacologic inactiva......阅读全文
