Fig. 5. SNORD3A expression is regulated by Meis1 in breast cancer cells.

a Schematic illustration of the Meis1-binding sites in the potential SNORD3A promoter predicted by JASPAR database (http://jaspar.binf.ku.dk). b, c qRT-PCR was performed to detect the expression levels of Meis1 in breast cancer cell lines (b) and in paired breast cancer tissues and normal mammary tissues (n = 26) (c). d The correlation between Meis1 and SNORD3A expression in breast cancer tissues was analyzed. e, f Meis1 overexpression resulted in elevated mRNA level of SNORD3A (e) and protein level of UMPS in MCF-7 and MDA-MB-231 cells (f). g Enrichment of Meis1 protein on the SNORD3A promoter was determined by ChIP-qPCR assay. Student’s t test, mean ± s.d. **p < 0.001, ***p < 0.001, ****p < 0.0001.
