DKK1 and prostate carcinoma: <h4>Objective</h4>This study investigated the anti-prostate cancer mechanism of dictamnine (DIC), focusing on its potential to reverse EMT via DKK1-mediated Wnt/β-catenin inhibition and modulate the tumor microenvironment.<h4>Methods</h4>Cell viability, proliferation, migration, and invasion were assessed using CCK-8, colony formation, EdU, wound healing, and Transwell assays.
