[Yishen Tonglong Decoction inhibits the epithelial-mesenchymal transition and Ras/ERK signaling pathway in human prostate cancer DU-145 cells].

Objective: To observe the effect of Yishen Tonglong Decoction (YTD) on the epithelial-mesenchymal transition (EMT) and Ras/ERK signaling pathway in human PCa DU-145 cells and explore its action mechanism.

Methods: We treated human PCa DU-145 cells with normal plasma (the blank control) or plasma containing 5% (low-dose), 10% (medium-dose) and 15% (high-dose) YTD. After intervention, we examined the proliferation of the DU-145 cells in different groups with CCK-8 and their apoptosis by Annexin V/PI double staining.
