Expression of miR-29c in breast cancer cells.

<p>(a) qRT-PCR results of miR-29c expression in breast cancer cell lines relative to expression in normal breast epithelial cell line 184A1 (RQ, relative quantity). MiR-29c expression organized by subtype reveals decreased expression in basal-like breast cancer cell lines (red), compared to luminal cell lines (black) and claudin-low cell lines (purple). (b) Expression of miR-29c in basal-like cell lines is statistically significantly lower than expression in luminal and claudin-low (p = .015). (c) TCGA data showed significantly lower expression of miR-29c in basal-like tumors compared to luminal A tumors (****p< 0.0001).
