In addition, we employed a web-based tool named starBase, and found that KRAS is up-regulated in BRCA, CHOL, ESCA, HNSC, LIHC, LUAD, LUSC, STAD, and UCEC in tumor samples compared to adjacent normal tissues, which are consistent with findings from the TIMER and UALCAN datasets (Table 2). The gene discussed is KRAS; the disease is neoplasm.
