Fig. 4From: Downregulation of miR-451 in cholangiocarcinoma help the diagnsosi and promotes tumor progressionRegulatory effect of miR-451 on ATF2 evaluated by luciferase reporter (A) and PCR (B) in CCLP1 cell. ATF2 was found to bind with miR-451 with several binding sites and was negatively regulated by miR-451. ***P < 0.001Back to article page
