Supplementary Figure 1. Potential targets were measured in MDA-MB-231 or MCF-7 cells transiently transfected with miR-193a-5p mimics, miR-193a-3p mimics, or control oligonucleotides

(a) NLN expression was examined after transfection of MAD-MB-231 (left panels) and MCF-7 (right panels) cells with miR-193a-5p mimics. (b) The expression of 10 putative targets of miR-193a-3p was examined using real-time PCR after transfection of MAD-MB-231 (upper panel) and MCF-7 (below panel) cells with miR-193a-3p mimics. (c) The levels of the DCAF7 protein were examined using western blotting after transfection of MDA-MB-231 and MCF-7 cells with miR-193a-3p mimics.

Supplementary Figure 2. The PLAU is a direct target of miR-193a-3p in breast cancer cells. Schema of the luciferase constructs. The miR-193a target sequence in the 3'UTR region of PLAU is shown in the upper panel andthe mutant of its 3'-UTR is shown in red. Relative luciferase activity of the reporter with the 3'UTR and 3'UTR(mut) of PLAU genes was determined after cotransfection of breast cancer cellswith miR-193a-3p mimics. Fireflyluciferase activity served as a normalisation control.

Supplementary Figure 3

(a) The sequences of artificial targets of miR-193a-5p and miR-193a-3p are shown. (b) and (c) Relative luciferase activity of reporters with artificial target genes was determined after cotransfection of breast cancer cells with miR-193a-5p and miR-193a-3p mimics. Fireflyluciferase activity served as a normalisation control.
