XPOT and cancer: To achieve this, we defined a group of prognostic risk genes using LASSO-Cox algorithms based on PCUGs, PCDGs, PCCUPs, and PCCDPs, among which XPOT, SLC16A3, HM13, ACADS, MSRA, FXYD1A, TG9A, PLOD3, ADGRG1, PHF3, MAOB, and DYSF were identified as risk genes in at least two different cancer types.
