MicroRNAs (miRNAs) possess an important regulating effect among numerous renal
diseases, while their functions in the process of epithelial-to-mesenchymal
transition (EMT) after podocyte injury remain unclear. The purpose of our study
is to identify the potential functions of miR-30a in EMT of podocytes and explore
the underlying mechanisms of miR-30a in the impaired podocytes. The results
revealed that downregulation of miR-30a in podocyte injury animal models and
patients, highly induced the mesenchymal markers of EMT including Collagen I,
Fibronectin and Snail. Furthermore, overexpression of miR-30a enhances epithelial
markers (E-cadherin) but diminished mesenchymal markers (Collagen I, Fibronectin
and Snail) in podocytes. In addition, we established miR-30a target NFATc3, an
important transcription factor of Non-canonical Wnt signaling pathway. More
importantly, our findings demonstrated that the augmentation of miR-30a level in
podocytes inhibits the nuclear translocation of NFATc3 to protect cytoskeleton
disorder or rearrangement. In summary, we uncovered the protective function of
miR30a targeting NFATc3 in the regulation of podocyte injury response to EMT.
