To further evaluate COMMD2 expression in human cancers, the UALCAN database was evaluated, revealing that the COMMD2 expression levels in BLCA, CHOL, COAD, ESCA, GBM, HNSC, LIHC, LUSC and STAD tissues were significantly higher than those in the corresponding normal tissues (Figures 1B–J). This evidence concerns the gene COMMD2 and cancer.
