Placental dysfunction underlies most IUGR, and causes fetal oxidative stress which may impact on cardiac development. Accordingly, we investigated whether antenatal melatonin treatment, which possesses antioxidant properties, may afford cardiovascular protection in these vulnerable fetuses. IUGR was induced in sheep fetuses using single umbilical artery ligation on day 105\u2013110 of pregnancy (term 147). Study\u00a01: melatonin (2\u00a0mg\u00a0h<jats:sup>\u22121<\/jats:sup>) was administered <jats:sc>i.v.<\/jats:sc> to ewes on days\u00a05 and 6 after surgery. On day\u00a07 fetal heart function was assessed using a Langendorff apparatus. Study\u00a02: a lower dose of melatonin (0.25\u00a0mg\u00a0h<jats:sup>\u22121<\/jats:sup>) was administered continuously following IUGR induction and the ewes gave birth normally at term. Lambs were killed when 24\u00a0h old and coronary vessels studied. Melatonin significantly improved fetal oxygenation <jats:italic>in vivo<\/jats:italic>. Contractile function in the right ventricle and coronary flow were enhanced by melatonin. Ischaemia\u2013reperfusion\u2010induced infarct area was 3\u2010fold greater in IUGR hearts than in controls and this increase was prevented by melatonin. In isolated neonatal coronary arteries, endothelium\u2010dependent nitric oxide (NO) bioavailability was reduced in IUGR, and was rescued by modest melatonin treatment. Melatonin exposure also induced the emergence of an indomethacin\u2010sensitive vasodilation. IUGR caused marked stiffening of the coronary artery and this was prevented by melatonin. Maternal melatonin treatment reduces fetal hypoxaemia, improves heart function and coronary blood flow and rescues cardio\u2010coronary deficit induced by IUGR.<\/jats:p><\/jats:sec>","DOI":"10.1113\/jphysiol.2014.270934","type":"journal-article","created":{"date-parts":[[2014,4,8]],"date-time":"2014-04-08T02:40:44Z","timestamp":1396924844000},"page":"2695-2709","source":"Crossref","is-referenced-by-count":58,"title":["Maternal
