Abstract
OBJECTIVE
Mesenchymal-epithelial transition (MET) is an important part of kidney development. However, the role of microRNA (miRNA) in MET and the regulating mechanism is still not well known.
MATERIALS AND METHODS
qRT-PCR and western blot were performed to detect the expression of miR-1 and miR-802 and related protein expression. Luciferase reporter assay and western blot were used to identify the target of miR-1 and miR-802. Confocal microscopy was used to analyze the MET process.
RESULTS
We demonstrated that miR-1 expression was downregulated and miR-802 expression was upregulated during kidney development. And during the process, proteins levels of Wnt-4 and β-catenin changed significantly. In MDCK cells, overexpression of Wnt-4 inhibited the expression of β-catenin, and promote the MET, and overexpression of β-catenin inhibited MET. Further studies suggested that miR-1 and miR-802 regulated MET by binding to Wnt-4 and β-catenin mRNA, regulated the expression of Wnt-4 and β-catenin. In conclusion, miR-1 and miR-802 regulate MET during kidney development by regulating Wnt-4/β-catenin signaling.
