AIM To investigate the underlying molecularmechanisms of miR-451 to inhibit proliferation ofesophageal carcinoma cell line EC9706.METHODS： Assays for cell growth, apoptosis andinvasion were used to evaluate the effects of miR-451expression on EC cells. Luciferase reporter and Westernblot assays were used to test whether cyclin-dependentkinase inhibitor 2D （CDKN2D） and MAP3K1 act as majortargets of miR-451.RESULTS： The results showed that CDKN2D andMAP3K1 are direct targets of miR-451. CDKN2D andMAP3K1 overexpression reversed the effect of miR-451.MiR-451 inhibited the proliferation of EC9706 bytargeting CDKN2D and MAP3K1.CONCLUSION： These findings suggest that miR-451might be a novel prognostic biomarker and a potentialtarget for the treatment of esophageal squamous cellcarcinoma in the future.
