CDC20 and glioblastoma: To determine the involvement of CDC20 gene expression in cancer and whether CDC20 is a target of omaveloxolone, we analysed the expression of the CDC20 gene in patients with GBM by using GEPIA 2 (http://gepia2.cancer‐pku.cn/#analysis) and DriverDBv4 (http://driverdb.bioinfomics.org/) software.
