OBJECTIVE
To study the effect of Notoginsenoside Rgl on p38 mitogen activated protein kinase (p38MAPK) expression in pulmonary artery smooth muscle cells (PASMCs) cultured in hypoxia hypercapnia.
METHODS
SD rat PASMCs was primary cultured, the cells of passage 2- 5 were divided into six groups:
Pulmonary arterial hypertension (PAH) is a disease of the small pulmonary arteries characterized by increased vascular resistance. Pulmonary vasoconstriction has been proven to play a pivotal role in PAH. We have previously hypothesized that Panax notoginseng saponins (PNS) might attenuate
OBJECTIVE
To explore the protective function and mechanism of notoginsenoside Rb1 against hypoxia hypercapnia-induced pulmonary vasoconstriction (HHPV).
METHODS
The pulmonary artery smooth muscle cells of healthy male SD rats were primarily cultured and the second to the fifth subcultured cells were
The aim of the present study was to investigate the effect of notoginsenoside Rb1 (Rb1) on the ERK and p38 MAPK pathways in primary cultured pulmonary arterial smooth muscle cells (PASMCs) exposed to hypoxia and hypercapnia, in order to elucidate the mechanism underlying the effect of Rb1 on hypoxia
