Dilatation of the Ductus Arteriosus by Diazoxide in Fetal and Neonatal Rats
We previously reported that ATP-sensitive potassium (KATP) channels regulate ductal constriction in response to oxygen [1]. Diazoxide is a KATP channel opener while the usefulness of diazoxide for hyperinsulinemi...

Constriction of the Ductus Arteriosus with KATP Channel Inhibitors
The cause of fetal death by sulfonylureas (SUs), used for diabetes in pregnancy in the early 1960s, remained unsolved for decades. In 1993, Nakanishi discovered constriction of ductus arteriosus (DA) strips in...

Fetal and Neonatal Ductus Arteriosus Is Regulated with ATP-Sensitive Potassium Channel
The fetal patency and neonatal closure of the ductus arteriosus (DA) are regulated with oxygen and prostaglandins. The proposed oxygen sensors of fetal and neonatal DA include P450-endothelin and the Kv channe...
