Fig. 3. SNORD3A promotes UMPS expression via interacting with miR-185-5p.

a Schematic illustration of the interaction between SNORD3A and miR-185-5p predicted with DIANA tools (http://carolina.imis.athena-innovation.gr/diana_tools/web/index.php) and between miR-185-5p and UMPS mRNA 3′-UTR predicted by TargetScan (http://www.targetscan.org/vert_72/). b The interaction between SNORD3A and miR-185-5p and the minimum free energy (mfe) were predicted with the RNAhybrid software (https://bibiserv.cebitec.uni-bielefeld.de/rnahybrid). c MS2-RIP assay followed by qRT-PCR to detect the association between SNORD3A and miR-185-5p. miR-191-5p served as a negative control. d Luciferase activity demonstrated that miR-185-5p targeted SNORD3A. e Western blot was performed to detect UMPS protein levels in MCF-7 and MDA-MB-231 cells after transfection with miR-185-5p inhibitor. f Luciferase activity indicated that miR-185-5p targeted UMPS. g miR-185-5p expression levels in human breast cancer cell lines were detected by qRT-PCR. h miR-185-5p levels in breast cancer tumor tissues and paired non-tumorous mammary tissues were examined by qRT-PCR (n = 26). Student’s t test, mean ± s.d. **p < 0.01, ***p < 0.001, ****p < 0.0001.
