The invention belongs to the technical field of cancer treatment, and discloses a method for inhibiting castration-resistant prostate cancer proliferation and metastasis by promoting collagen degradation through targeting ADAMTS1. According to the method, ADAMTS1 is determined to be a mechanism key point for linking epigenetic reprogramming with biomechanical microenvironment destruction. The ADAMTS1 is reactivated to degrade a collagen-rich matrix, the FAK / MAPK mechanical transduction signaling pathway is inhibited, and the epithelial-mesenchymal transition (EMT) is reversed. The strategy not only achieves more than 90% of tumor inhibition effect, but also exhausts immunosuppressive macrophages and regulatory T cells to reverse immunosuppression by enhancing toxic CD8 + T cell infiltration. The research determines that epigenetic-ECM coevolution is a symbolic feature of CRPC, and provides a reasonably designed combination therapy for treating castration-resistant prostate cancer.
