While in the GEPIA database, the results indicated that the expression of these genes in tumors was higher than that of normal controls, and the expression of CXCL11, TAP1, CXCL13, STAT1, UBD, LAMP3, CXCL9, PSMB9, USP18, and WARS was increased significantly in ovarian cancer samples (Figure 5B). Here, PSMB9 is linked to ovarian carcinoma.
