We obtained the ULBP1 gene in COAD tumor tissues and normal tissues from the GEPIA database that matched the information from the GTEx database and found that ULBP1 expression was up-regulated in tumor tissues and also found that the expression level of ULBP1 gene increased with the progression of tumor stages (Figures 2A,B). The gene discussed is ULBP1; the disease is neoplasm.
