Notoginsenoside R1 Improved Hypoxic Pulmonary Hypertension by Inhibiting Glycolysis-Mediated Pulmonary Arterial Vascular Remodeling.

ABSTRACT: Hypoxic pulmonary hypertension (HPH) lacks effective treatments. The research is designed to examine the effectiveness of Notoginsenoside R1 (NGR1) in addressing HPH and to explore its molecular mechanisms. Under hypoxic conditions, we created a rat model of HPH and treated the animals with NGR1. We assessed the therapeutic effects of NGR1 on HPH through hemodynamic measurements and pulmonary artery vascular remodeling. We employed transcriptomic analysis to evaluate gene expression changes in HPH rats. We conducted untargeted metabolomics to examine how NGR1 influences the metabolic profile of HPH rats. NGR1 treatment significantly improved hemodynamic parameters and ameliorated pulmonary artery vascular remodeling in HPH rats. Transcriptomic analysis identified Pck1 as the most si
