MiR-203a is differentially expressed during branching morphogenesis and EMT in breast progenitor cells and is a repressor of peroxidasin
Publisher's version MicroRNAs regulate developmental events such as branching morphogenesis, epithelial to mesenchymal transition (EMT) and its reverse process mesenchymal to epithelial transition (MET). In this study, we performed small RNA sequencing of a breast epithelial progenitor cell lin...

In this study, we performed small RNA sequencing of a breast epithelial progenitor cell line (D492), and its mesenchymal derivative (D492M) cultured in three-dimensional microenvironment. Among the most downregulated miRNAs in D492M was miR-203a, a miRNA that plays an important role in epithelial differentiation. Increased expression of miR-203a was seen in D492, concomitant with increased complexity of branching. When miR-203a was overexpressed in D492M, a partial reversion towards epithelial phenotype was seen. Gene expression analysis of D492M and D492MmiR-203a revealed peroxidasin, a collagen IV cross-linker, as the most significantly downregulated gene in D492MmiR-203a. Collectively, we demonstrate that miR-203a expression temporally correlates with branching morphogenesis and is suppressed in D492M. Overexpression of miR-203a in D492M induces a partial MET and reduces the expression of peroxidasin. Furthermore, we demonstrate that miR-203a is a novel repressor of peroxidasin. MiR-203-peroxidasin axis may be an important regulator in branching morphogenesis, EMT/MET and basement membrane remodeling.
