Abstract:
Objective To study salinomycin (Sal) enhance the sensitivity of liver cancer cell to 5‐fluorouracil (5‐FU) and its mechanism ,and to provide drug‐resistant primary hepatocellular carcinoma (HCC) patients with a new treatment .Methods Hepa‐toma cell line HepG2 ,SMMC‐7721 ,M HCC‐97H were used for the research .The effect of Sal combined with 5‐FU on the cell pro‐liferation inhibition rate ,colony formation ,apoptosis and tumor stem cell proliferation were detected by the M TT assay ,colony for‐mation assay ,flow cytometry .And the effect on Wnt/‐catenin when Sal combined with 5‐FU were detected by Western‐blot . Results Sal combined with 5‐FU significantly inhibited the liver cancer cell proliferation and colony formation and induced cell ap‐optosis ,showed the synergistic effect .5‐FU promoted the proliferation of hepatocarcinoma stem ,but Sal reduced the function of 5‐FU .At the same time Sal could inhibit the Wnt/‐catenin signal pathway .Conclusion The Sal can increase the sensitivity of hepato‐cellular carcinoma cells to 5‐FU by inhibiting Wnt/‐catenin signal pathway ;Sal combined with 5‐FU could provide drug‐resistant HCC patients with a new treatment .
