MiR-378a-3p upregulation suppresses the TGF-β/SMAD pathway. (A) The mRNA expression levels of TGF-β1, SMAD2 and SMAD3 in OS cells transfected with NC mimics or miR-378a-3p mimics were determined by RT-qPCR analysis. Significance was analyzed by Student’s t-test. (B,C) Western blot measured the protein levels of TGF-β1, SMAD2, SMAD2 (phospho S255), SMAD3, and SMAD3 (phospho T179) in OS cells transfected with sh-LINC00174 or sh-NC group. Significance was analyzed by Student’s t-test. *p < 0.05.
