    “…Previous studies demonstrated that Angiotensin II Receptor 1 (AGTR1) may play an important role in the development of high-altitude pulmonary edema. We envisaged a role for AGTR1 gene variants in the pathogenesis of HAPE and investigated their potential associations with HAPE in a Han Chinese population. …”

    “…BACKGROUND: Alterations in the gut microbiota have been observed in patients with pulmonary hypertension (PH), though whether the roles of the gut microbiota in PH at different altitudes are the same is unknown. This study aims to evaluate the associations of the gut microbiome with PH in highlanders and lowlanders. …”
