Fig. 4. E2F1 and CCND1 are two direct targets of miR-93.
a 210 targets were predicted for miR-93 in four online databases. b The mRNA expression levels of 12 candidate target genes were measured in Bads-200 cells transfected with NC/miR-93. c, d E2F1 and CCND1 were upregulated in tumor samples of breast cancer, by comparing their mRNA levels in clinical tissues (c) and TCGA samples (d). e The dual luciferase assays were performed in Bads-200 cells. f MiR-93 notably downregulated the protein levels of E2F1 and CCND1 in Bads-200 cells, with or without PTX. g Representative images of Bads-200 xenografts with IHC staining of E2F1 and CCND1. Scale bars: (main) 200 μm, (inset) 50 μm. h, i The mRNA and protein levels of E2F1 and CCND1 were measured in BCap37, Bats-72, and Bads-200 cells. Bars indicate the mean ± SD of three independent replicates. *P < 0.05, **P < 0.01, ***P < 0.001.
