Prostaglandin E2 Activates YAP and a Positive-signaling Loop to Promote Colon Regeneration Following Colitis but Also Carcinogenesis in Mice

摘要

BACKGROUND & AIMSProstaglandin E2 (PGE2) is mediator of inflammation that regulates tissue regeneration, but its continual activation has been associated with carcinogenesis. Little is known about factors in the PGE2 signaling pathway that contribute to tumor formation. We investigated whether yes associated protein 1 (YAP1), a transcriptional co-activator in the Hippo signaling pathway, mediates PGE2 function.
