Abstract
MicroRNAs (miRNAs) post-transcriptionally regulate gene expression by targeting the 3′ untranslated region (UTR) of target genes, and serve diverse roles in cell proliferation, differentiation and apoptosis. However, the association between miR-16-2-3p and 3-phosphoinositide-dependent protein kinase-1 (PDPK1) in nonsyndromic cleft lip (NSCL) remains unclear. In the present study, a luciferase activity assay indicated that miR-16-2-3p negatively regulated PDPK1 in maxillary primordium mesenchymal cells (MPMCs). In addition, it was confirmed that the expression levels of miR-16-2-3p was markedly increased in cleft lip tissues compared with those in adjacent normal lip tissues. A negative correlation between miR-16-2-3p and PDPK1 in cleft lip tissues was observed. Furthermore, miR-16-2-3p inhibited cell proliferation and migration, and induced apoptosis of MPMCs via repressing PDPK1. Finally, miR-16-2-3p exerted its suppressive role in MPMCs by inhibiting the PDPK1/protein kinase B signaling pathway. These results indicate that miR-16-2-3p may inhibit cell proliferation and migration, and promote apoptosis in MPMCs through repression of PDPK1 and may be a potential target for future clinical prevention and treatment of NSCL.
