63 results about "Castration" patented technology

Castration (also known as orchidectomy) is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles: the male gonad. Surgical castration is bilateral orchidectomy (excision of both testes), and chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization (preventing the castrated person or animal from reproducing); it also greatly reduces the production of certain hormones, such as testosterone. Surgical castration in animals is often called neutering.

Application of new Lnc-FLJ in the treatment of castration-resistant prostate cancer

The present invention belongs to the field of biomedicine technology, and relates to the application of the Lnc-FLJ gene in the treatment of castration-resistant prostate cancer. The application of the Lnc-FLJ gene inhibitor in the preparation of prostate cancer drugs. The present invention discovered for the first time that Lnc-FLJ can inhibit the proliferation and autophagy of castration-resistant prostate cancer. Lnc-FLJ is more highly expressed in castration-resistant prostate cancer cells and prostate cancer tissues with higher malignancy. Inhibiting Lnc-FLJ can inhibit the occurrence and development of castration-resistant prostate cancer. The preparation of Lnc-FLJ small molecule inhibitor shRNA is used to treat castration-resistant prostate cancer and cancer insensitive to enzalutamide, thereby inhibiting the AR signaling pathway. The present invention provides new ideas for further studying the pathogenesis of castration-resistant prostate cancer and the function of the Lnc-FLJ gene, and provides a new direction for the development of castration-resistant prostate cancer drugs.

Targeting ADAMTS1 to inhibit castration-resistant prostate cancer proliferation and metastasis by promoting collagen degradation

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.

Application of nefenavir

The invention relates to the technical field of biological medicine, and particularly discloses application of nefenavir. Nefinavir is used for preparing a medicine for treating or preventing castration-resistant prostate cancer, and the medicine can specifically up-regulate expression of DHCR7, induce DNA damage of tumor cells and activate a cell cycle arrest pathway mediated by periodic protein of the cells so as to inhibit key biological processes such as proliferation of the tumor cells, cholesterol metabolism and the like; especially, formation and amplification of multinuclear giant cells in castration-resistant prostate cancer can be effectively inhibited by up-regulating expression of DHCR7, so that malignant progression of multinuclear giant cell mediated tumors and treatment of drug resistance are blocked. Finally, the castration-resistant prostate cancer is prevented and treated, and the technical bottlenecks that an existing castration-resistant prostate cancer treatment means is limited in curative effect, and the drug resistance and metastasis capability mediated by multinuclear giant cells are difficult to inhibit in a targeted manner are solved.
