DHX32 and hepatocellular carcinoma: We found that the expression level of DHX32 mRNA and protein were significantly higher in five HCC cell lines, including HepG2 (p < .001), Hep3B (p < .001), Huh7 (p < .01), SNU-181 (p < .001), and SNU-387 (p < .001) cells, than those in human normal immortalized liver cell LO2 (Figure 1(A and B)).
