Prostate cancer (PC) is one of the most common types of cancers among men, referring to the uncontrolled growth of the prostate gland. It is increasingly recognized that the interaction of the glioma-associated oncogene (GLI) pathway and androgen receptor affects PC progression. Nevertheless, the effects of resveratrol on PC progression via Hedgehog (HH) signaling remain unexplored. In this study, the castration-sensitive and castration-resistant xenograft models in mice are systematically established using two different PC cell lines (LNCaP and PC-3). Further, the Western blotting, immunohistochemistry, MTT, Transwell, and RT-qPCR analyses are performed to verify the mechanistic views of resveratrol on PC and HH signals in vitro and in vivo. Resveratrol showed epithelial-mesenchymal transition (EMT) progression, inhibiting the tumor size and expression levels of vimentin, vascular endothelial growth factor (VEGF), and matrix metalloproteinases (MMP) 7, as well as upregulating the expression profiles the E-cadherin and Annexin 2. Moreover, resveratrol inhibited the hedgehog (HH) signals and tumor necrosis factor receptor (TNFR)-associated factor 6 (TRAF6) levels exhibiting the therapeutic action on castration-sensitive and castration-resistant PC cell lines. In summary, the overexpression of TRAF6 enhanced the viability and EMT progression of cancer cells. The resveratrol could alleviate the TRAF6 effect and regulate the HH signal to affect PC progression.
