In this study, we evaluated the effect of Rodgersia podophylla leave extracts (RPL) on ${\beta}$-catenin level in human cancer cells. RPL dose-dependently inhibited cell proliferation in SW480, A549, MDA-MB-231, PC-3 and AsPC-1 cells. RPL dramatically decreased ${\beta}$-cateni...
In this study, we evaluated the effect of Rodgersia podophylla leave extracts (RPL) on ${\beta}$-catenin level in human cancer cells. RPL dose-dependently inhibited cell proliferation in SW480, A549, MDA-MB-231, PC-3 and AsPC-1 cells. RPL dramatically decreased ${\beta}$-catenin protein level in all cancer cells. However, decreased level of ${\beta}$-catenin mRNA expression was observed in A549 and AsPC-1 cells. In addition, RPL dramatically attenuated cyclin D1 mRNA expression in all cancer cells. MG132 decreased the downregulation of ${\beta}$-catenin protein level induced by RPL in all cancer cells, while RPL-induced downregulation of ${\beta}$-catenin was inhibited by the inhibition of $GSK-3{\beta}$ by LiCl in MDA-MB-231 cells. RPL phosphorylated ${\beta}$-catenin and $GSK-3{\beta}$. In addition, the inhibition of $GSK-3{\beta}$ by LiCl attenuated RPL-induced ${\beta}$-catenin phosphorylation. Based on these findings, RPL may be a potential candidate for the development of chemopreventive or therapeutic agents for human cancer.
