(A, C and E) qRT-PCR revealed that ATF1, CREB1, and CREB3 expression was higher in HCC tissues than in normal tissues. (B, D and E) Immunohistochemical analysis showed that ATF1, CREB1, and CREB3 expression was significantly higher in HCC tissues than in adjacent normal tissues (*p < 0.05; **p < 0.01; ***p < 0.001).
