Pulmonary hypertension (PH), characterized by pulmonary artery and right ventricle remodeling, poses a significant risk of mortality in infants, children, and adolescents.

Offspring were administered monocrotaline (MCT) at 6 weeks of age (6-wo) to induce PH. Mechanistic experiments were conducted at 10-week-old (10-wo). Protein expression of NADPH oxidases, DNA methyltransferases, and autophagy-related markers was analyzed by Western blot. Morphological changes and the severity of PH were evaluated via hematoxylin and eosin (HE) staining and echocardiography, respectively.

In vivo treatment with chloroquine inhibited autophagy and ameliorated PH development in offspring exposed to maternal EC. Furthermore, N-acetylcysteine (NAC), an antioxidant, attenuated maternal EC exposure-induced oxidative stress, DNA hypomethylation, and excessive autophagy, thereby improving PH. DNA hypermethylation also reversed PH development, accompanied by reduced oxidative stress and suppressed autophagy.
