We first assessed NUDT1 expression in Pan-cancer data from TIMER database; the results showed that the expression of NUDT1 was upregulated in 18 tumors, including BCLA, BRCA, CHOL, COAD, ESCA, HNSC, KICH, KIRC, KIRP, LIHC, LUAD, LUSC, PRAD, READ, SKCM, STAD, THCA, and UCEC (Figure 1(a)). The gene discussed is NUDT1; the disease is cancer.
