Cathepsin B belongs to a family of lysosomal cysteine proteases known as the cysteine cathepsins and plays an important role in intracellular proteolysis. In humans, cathepsin B is encoded by the CTSB gene. Cathepsin B is upregulated in certain cancers, in pre-malignant lesions, and in various other pathological conditions. WebHere, we investigated the radioresistant role of Cathepsin B (CTSB), one important member of cysteine proteases, in GBM cell lines. A protease array kit was used to test GBM cells before and after irradiation. Nude mice were implanted with GBM cells to generate orthotopic xenografts for in vivo studies.
