Melatonin Decreases Pulmonary Vascular Remodeling and Oxygen Sensitivity in Pulmonary Hypertensive Newborn Lambs

Abstract: Background: Chronic hypoxia and oxidative stress during gestation lead to pulmonary hypertension of the neonate (PHN), a condition characterized by abnormal pulmonary arterial reactivity and remodeling. Melatonin has strong antioxidant properties and improves pulmonary vascular function. Here, we aimed to study the effects of melatonin on the function and structure of pulmonary arteries from PHN lambs.Methods: Twelve lambs (Ovis aries) gestated and born at highlands (3,600 m) were instrumented with systemic an… Show more

“…Normative data for novel quantitative techniques are currently being established and verified although thresholds for intervention remain unclear. Echocardiography may also play a role in the objective assessment of new or potential therapeutic modalities for PH including sildenafil, hydrocortisone, melatonin, and citrulline . Further neonatal studies should evaluate if utilizing objective echocardiography techniques of RV function in the setting of PH improves short and long‐term neonatal medical and neurodevelopmental outcomes.…”

“…Para este estudio se utilizaron 10 corderos (Ovis aries) recién nacidos con hipertensión pulmonar, modelo caracterizado en estudios previos 7,15,16,22,23 . Las ovejas madres de estos corderos concibieron y gestaron en hipoxia hipobárica en el Centro Internacional de Estudios Andinos de la Universidad de Chile (INCAS, Putre a 3.600 msnm).…”

“…La extracción de proteína a partir de pulmón se realizó mediante homogenización mecánica en buffer RIPA como se describe en trabajos de Torres F et al y Astorga CA et al 15,16 . Los lisados de proteína (1-40 μg según proteína) fueron separados por electroforesis en geles de poliacrilamida SDS-PAGE (4% de gel concentrador y 10% de gel de corrida al 10%).…”
