However, it's still unknown whether functions of coronary arteries (COA) in adult offspring would be influenced by PH. The present study aimed at effects of PH on vascular tone of COA and its related mechanisms.MethodsCoronary arteries of adult offspring exposed to hypoxic or normoxic circumstances during gestational day 5 to 21 were collected. Wire myograph system, whole-cell patch clamp technique, IonOptix MyoCam system, PCR, and western blot were used to detect vascular function of adult offspring COA.Key findingsPH significantly attenuated serotonin- and phorbol 12, 13-dibutyrate (PDBu)-induced constriction. Iberiotoxin potentiated PDBu-induced constriction and the effect was augmented by PH, however, no significant differences were found in whole-cell BKCa channel currents and its protein expression. Nifedipine inhibited PDBu-mediated constriction and the inhibitory effect was reduced in PH group, and whole-cell calcium channel current was decreased in offspring COA. Besides, PH reduced the capability of calcium release from the endoplasmic reticulum in COA. The phosphorylated PKCβ protein expression at Ser660 site, not Thr641 site, was significantly decreased in PH offspring. Chronic hypoxia during pregnancy attenuated PDBu-mediated constriction in offspring COA, presumably through decreased phosphorylated PKCβ at serine660 sites and decreased intracellular calcium-related weaker PKC activation.SignificanceThe findings provided new information on the influence of prenatal hypoxia on COA, and suggested potential use of PKCβ-serine660 for early prevention of coronary heart diseases in developmental origins."xsd:string |
