Overexpression of calpain small subunit 1 <t>(Capn4)</t> reversed the inhibitory effect of miR-124 on the Wnt/β-catenin signaling pathway. HONE1 and CNE2 cells were transfected with miR-124 or co-transfected with miR-124 and <t>pcDNA-Capn4</t> ( A and B ). Western blot analysis revealed that Capn4 overexpression reversed the decreased β-catenin, cyclin D1, and c-Myc protein levels caused by the overexpression of miR-124 in HONE1 and CNE2 cells. Data are shown as mean ± standard deviation (n=3). * P
