Abrogation of Akt signaling by Isobavachalcone contributes to its anti-proliferative effects towards human cancer cells.

abstract：:We previously reported that prostaglandin E(2) contributes to colon carcinogenesis through its binding to the prostaglandin E receptor subtype EP(1) using a genetic approach in EP(1)-knockout mice and a pharmacological approach with the EP(1) selective antagonist, ONO-8711. In the present study, we examined the effect...
