Research Abstract

Prostaglandin E induces vasodilation and intimal thickening(IT) in the ductus arteriosus via activation of adenylyl cyclases(AC). We revealed that AC6 is responsible for hyaluronan production and AC2 inhibited it. Stimulation of both AC2 and AC6 by FD1 induced longer vasodilation without IT. FD1 may be a novel alternative therapy to currently available PGE therapy for ductus arteriosus.
