ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of serum containing Chinese medicine (CM) Sanpi Pingwei (, SPPW) formula on the proliferation and apoptosis of human SGC-7901 cells and the possible mechanism.</p><p><b>METHODS</b>Serum containing CM SPPW formula (SPPW serum) was prepared by a serum pharmacology method. Human SGC-7901 cells were incubated with SPPW serum at three different concentrations and with the anticancer drug 5-fluorouracil (5-FU), respectively. Cell proliferation was assessed by MTT assay, and cell apoptosis was detected by flow cytometry assay. Real-time quantitative polymerase chain reaction (RT-PCR) and Western blot assay were employed to confirm the expressions of Bcl-2, Bax and p53 in SGC-7901 cells at mRNA and protein levels, respectively.</p><p><b>RESULTS</b>SPPW serum suppressed the proliferation of SGC-7901 cells in a time- and dose-dependent manner. The colony forming rate of negative control was 48.2%, while those in the three SPPW serum groups and the 5-FU group decreased significantly (P<0.01). The number of colony forming units in the SPPW high dosage group was significantly smaller than that in the 5-FU group (P<0.01). MTT assay showed that SPPW serum restrained the proliferation of SGC-7901 cells, and the inhibition rate increased significantly in a dose-dependent manner. Annexin V/PI Assay suggested that SPPW serum induced the apoptosis of SGC-7901 cells significantly. RT-PCR and western blot assay indicated that SPPW serum upregulated the protein and mRNA expression levels of Bax and p53 in SGC-7901 cells, but downregulated the protein and mRNA expressions of Bcl-2.</p><p><b>CONCLUSIONS</b>SPPW formula inhibits the proliferation of SGC-7901 cells in vitro and induces the cell apoptosis. It plays an anticancer role by regulating the expressions of Bax, p53 and Bcl-2 in SGC-7901 cells.</p>
