Fig. 4. miR-185-5p is involved in SNORD3A-mediated chemosensitization to 5-FU in breast cancer cells.

a Ectopic expression of miR-185-5p diminished the effects of SNORD3A overexpression on the chemosensitization of MDA-MB-231 cells to 5-FU by MTS assay at 72 h post-treatment. b, c Colony numbers of MDA-MB-231 cells with simultaneous expression interference of SNORD3A and miR-185-5p were detected by colony-formation assay (b) and soft agar colony-formation assay (c). Scale bar, 100 μm. d SNORD3A overexpression increased the chemosensitivity of MDA-MB-231-derived tumors to 5-FU, but co-expressed miR-185-5p abrogated the effect of SNORD3A. n = 5/group. Student’s t test, mean ± s.d. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
