DDAH1 SNP rs480414 that protects against the development of pulmonary hypertension in bronchopulmonary dysplasia results in lower nitric oxide production in neonatal cord blood-derived lymphoblastoid cell lines.

Abstract excerpt

BACKGROUND: Bronchopulmonary dysplasia (BPD) is chronic lung disease of prematurity and pulmonary hypertension (PH) is a major contributor to morbidity and mortality in BPD patients. Nitric oxide (NO) is a vasodilator and apoptotic mediator made by NO synthase (NOS). NOS is inhibited by asymmetric dimethylarginine (ADMA), and dimethylarginine dimethylaminohydrolase (DDAH) hydrolyzes ADMA. Previously, in a BPD...
