    Author: Zhang J, Zhou CS, Liu S, Chen H, Yang C.
    Journal: Zhong Nan Da Xue Xue Bao Yi Xue Ban; 2008 Aug; 33(8):718-22. PubMed ID: 18772512.
    Abstract:
    OBJECTIVE: To investigate the effect of podophyllotoxin on human gastric cancer cell line SGC 7901 cells in vitro and in vivo, and to provide evidence for treatment of gastric cancer with podophyllotoxin. METHODS: SGC 7901 cells were treated with podophyllotoxin at various concentrations for different time. MTT assay, colony formation assay, and flow cytometry were performed to determine the effect of podophyllotoxin on the growth and apoptosis of SGC 7901 cells in vitro. Furthermore, xenograft experiment was performed to detect the effect of podophyllotoxin on the in vivo tumorigenicity of SGC 7901 cells. RESULTS: Podophyllotoxin inhibited the growth of SGC 7901 cells in a concentration- and time-dependent manner, decreased the colony formation rate of the cells, induced SGC 7901 cell apoptosis, arrested SGC 7901 cells at G2/M phases of cell cycle, and decreased the volume and weight of SGC 7901 cell xenografts in nude mice. CONCLUSION: Podophyllotoxin inhibits the growth of human gastric cancer SGC 7901 cells, induce the apoptosis of SGC 7901 cells in vitro, and inhibit the in vivo tumorigenicity of SGC 7901 cells, which provides evidence for treatment of gastric cancer using podophyllotoxin.
