Effects and mechanisms of the functional parts of Dahuang Zhechong Pill (大黄 虫丸) containing serum on platelet-derived growth factor-stimulated proliferation of vascular smooth muscle cells
摘要
To investigate and compare the effects and mechanisms of three functional parts of Dahuang Zhechong Pill (大黄 虫丸
DHZCP)
including drugs with the function of removing blood stasis and promoting blood circulation (FP-I)
drugs with the function of expelling heat and moistening dryness (FP-II)
and drugs with the function of nourishing yin and replenishing blood (FP-III) of DHZCP
on platelet-derived growth factor (PDGF)-stimulated vascular smooth muscle cells (VSMCs) proliferation with the method of serum pharmacology. VSMCs proliferation of rat was assayed by measuring the cell viability with the 3-(4
5-dimethylthiazol-2yl)-2
5-diphenyltetrazolium bromide (MTT) method. DNA synthesis in VSMCs was examined by detecting 5′-bromo-2′-deoxyuridine incorporation with the immunocytochemical method. Cycle of VSMCs was evaluated with flow cytometry. Expression of cyclin D1
p27
PKCα
and phosphorylated extracellular signal regulated kinase 1/2 (ERK1/2) was quantified by the Western blotting method. The FP-I and FP-III containing serum was capable of inhibiting PDGF-stimulated proliferation and DNA synthesis of VSMCs
arrested VSMCs in G phase
downregulated cyclin D1
and upregulated p27 expression (P <0.01 or P <0.05). The FP-I and FP-III containing serum also inhibited the PDGF-induced phosphorylation of tyrosine of ERK1/2 and PKCα expression (P <0.01 or P <0.05). FP-I and FP-III of DHZCP are able to inhibit VSMCs proliferation via interrupting PKCα-ERK1/2 signaling
modulating the expression of cell cycle proteins to result in arresting the cells in G phase. The inhibitory effect is mainly related to the function of removing blood stasis and promoting blood circulation
slightly to the function of nourishing yin and replenishing blood
but not to the function of expelling heat and moistening dryness.
