Figure 1. Identification of differentially expressed miRNAs in HER2-overexpressed breast epithelial cells.
MCF10A-Vector and MCF10A-HER2 were used to screen for differentially regulated miRNAs. a) Western blot analysis of HER2-downstream signaling pathways in MCF10A-Vector and MCF10A-HER2 cells. b) Differentially expressed miRNAs in HER2-overexpressed cells. Over 300 miRNAs were screened using qPCR analysis. The differentially expressed miRNAs were selected with the 2-fold change cutoff. c) Agarose gel picture depicting the expression of representative qPCR products from the miRNA screening.
