Interestingly, the result that high expression of KCNK1 was associated with a longer OS rate in HCC patients (HR=0.55, 95% CI: 0.38-0.79, and p=0.0012) was inconsistent with the difference analysis of the UALCAN database, which showed low KCNK1 expression in HCC. This evidence concerns the gene KCNK1 and hepatocellular carcinoma.
