Objective: To detect how safflower polysaccharide (SPS) affects cell proliferation of human hepatic cancer cell line SMMC-7721. Method: SMMC-7721 cells were treated with different concentrations(0

1.28 g·L-1) of SPS for 24
48 hours. The cell proliferation was assessed by methyl thiazolyl tetrazolium (MTT) assay. The proteins of cyclin B1 were compared by IHC. The expression of mRNA and protein of Cdc25B was compared by RT-PCR and Western blot. Result: The cell survival rate of SMMC-7721 cells was significantly inhibited by SPS in a dose-dependent and time-dependent manner
except 1.28 g·L-1 SPS group. The protein expression of cyclin B1 and Cdc25B was down-regulated compared with the control group at 48 hour. The mRNA of Cdc25B also decreased and had good dose-dependent. Conclusion: SPS can inhibit proliferation of SMMC-7721 cell by affecting expression of cycle regulation genes.
