Ginsenoside Rg1 alleviates vascular remodeling in hypoxia-induced pulmonary hypertension mice through the calpain-1/STAT3 signaling pathway
Background
Hypoxic pulmonary hypertension (HPH) is the main pathological change in vascular remodeling, a complex cardiopulmonary disease caused by hypoxia. Some research results have shown that ginsenoside Rg1 (Rg1) can improve vascular remodeling, but the effect and mechanism of Rg1 on hypoxia-induced pulmonary hypertension are not clear. The purpose of this study was to discuss the potential mechanism of action of Rg1 on HPH.
Methods
C57BL/6 mice, calpain-1 knockout mice and Pulmonary artery smooth muscle cells (PASMCs) were exposed to a low oxygen environment with or without different treatments. The effect of Rg1 and calpain-1 silencing on inflammation, fibrosis, proliferation and the protein expression levels of calpain-1, STAT3 and p-STAT3 were determined at the animal and cellular levels.
Results
At the mouse and cellular levels, hypoxia promotes inflammation, fibrosis, and cell proliferation, and the expression of calpain-1 and p-STAT3 is also increased. Ginsenoside Rg1 administration and calpain-1 knockdown, MDL-28170, and HY-13818 treatment showed protective effects on hypoxia-induced inflammation, fibrosis, and cell proliferation, which may be associated with the downregulation of calpain-1 and p-STAT3 expression in mice and cells. In addition, overexpression of calpain 1 increased p-STAT3 expression, accelerating the onset of inflammation, fibrosis and cell proliferation in hypoxic PASMCs.
Conclusion
Ginsenoside Rg1 may ameliorate hypoxia-induced pulmonary vascular remodeling by suppressing the calpain-1/STAT3 signaling pathway.
期刊介绍：
Journal of Ginseng Research (JGR) is an official, open access journal of the Korean Society of Ginseng and is the only international journal publishing scholarly reports on ginseng research in the world. The journal is a bimonthly peer-reviewed publication featuring high-quality studies related to basic, pre-clinical, and clinical researches on ginseng to reflect recent progresses in ginseng research.
JGR publishes papers, either experimental or theoretical, that advance our understanding of ginseng science, including plant sciences, biology, chemistry, pharmacology, toxicology, pharmacokinetics, veterinary medicine, biochemistry, manufacture, and clinical study of ginseng since 1976. It also includes the new paradigm of integrative research, covering alternative medicinal approaches. Article types considered for publication include review articles, original research articles, and brief reports.
JGR helps researchers to understand mechanisms for traditional efficacy of ginseng and to put their clinical evidence together. It provides balanced information on basic science and clinical applications to researchers, manufacturers, practitioners, teachers, scholars, and medical doctors.
