KCNK17 and hepatocellular carcinoma: We found that KCNK9 (p = 0.0286) is upregulated in HCC tissues compared with normal controls while KCNK2 (p = 0.0005), KCNK15 (p < 0.0001), and KCNK17 (p < 0.0001) are downregulated (Figure 5A), which is consistent with our analyses using data from the UALCAN database.
