Systematic analysis of molecular mechanism of resveratrol for treating pulmonary hypertension based on network pharmacology technology

Resveratrol is a polyphenolic antioxidant derived from plant products such as grapes. Previous studies explored the effects of resveratrol on pulmonary hypertension (PH). However, systematic research on the exact mechanism of action of resveratrol is still lacking; in particular, our knowledge on the molecule-gene interaction is limited. In this study, systematic pharmacology and bioinformatic approaches were employed to identify the potential targets of resveratrol for treating PH. Furthermore, core genes were identified by constructing a protein-protein interaction network and by conducting topology analyses. The results showed that the effect of resveratrol may be closely associated with targets such as AKT serine/threonine kinase 1 (AKT1), mitogen-activated protein kinase 3 (MAPK3), Sirtuin-1 (SIRT1) and proto-oncogene tyrosine-protein kinase Src (SRC), as well as biological processes such as cell proliferation, inflammatory response, and redox balance. The present study systematically elucidates the mechanisms by which resveratrol alleviates PH and provides a new perspective on drug research for this disease.
