Figure 2. Correlation between levels of 10 KCNKs and HCC patient clinicopathological characteristics. The highest mRNA levels for KCNK7/9/10 were found in tumors of grade 4 (E, F, G) while the lowest mRNA levels of KCNK3/13/15/17 were found in grade 4 tumors (C, H, I, J). Expression of KCNK1/2/5 did not vary with tumor grade (A, B, D). *p<0.05, **p<0.01, ***p<0.001.
