Effect of yifei huoxue granule on the proliferation and the TGF-beta activity of rat pulmonary artery smooth muscle cells induced by platelet-derived growth factor BB
OBJECTIVE: To explore the effects of Yifei Huoxue Granule (YFHXG) on the proliferation and the transforming growth factor-beta (TGF-beta) activity of rat pulmonary artery smooth muscle cells (PASMCs) induced by platelet-derived growth factor BB (PDGF-BB).
METHODS: Using tissue block adhering wall method, the primary rat PASMCs were cultured. PASMCs at the log phase growth were randomly divided into the control group, the PDGF-BB group, the PDGF-BB + high YFHXG group (at the final concentration of 7.5 mg/mL), the PDGF-BB + middle YFHXG group (at the final concentration of 1.5 mg/mL), and the PDGF-BB + low YFHXG group (at the final concentration of 0.3 mg/mL), respectively. MTT assay were employed to determine the cell proliferation rate of each group. Flow cytometric analyses were used to detect the cell cycle constituent ratio and the proliferation index (PI). In addition, TGF-beta protein's expression was determined by immunocytochemical assay (SP method).
RESULTS: Compared with the control group, the proliferation of PASMCs in the PDGF-BB group was obviously active (P<0.01). But when compared with the PDGF-BB group, along with the increased concentration of YFHXG, the growth of PASMCs was obviously inhibited, the cell ratio of G0/G1, phase obviously increased, the cell ratio of S + G2/M phase significantly decreased, and PI significantly decreased. Besides, the expression of TGF-beta protein decreased in a dose-dependent manner (P<0.05, P<0.01).
CONCLUSIONS: PDGF-BB could directly stimulate the proliferation of PASMCs. YFHXG had a significant inhibition on the proliferation of rat PASMCs induced by PDGF-BB and could regulate the expression of TGF-beta.
