Figure 5. Differential expression of KCNK2/9/15/17 mRNA in surgically removed HCC tissues. KCNK9 mRNA levels are elevated while KCNK2, KCNK15, and KCNK17 mRNA levels are decreased in HCC tissues compared with normal tissues as measured by qRT-PCR (A). KCNK9 protein levels are increased while KCNK2/15/17 protein levels are decreased in HCC tissues compared to controls, as measured by Western Blot (B).
