Among the 20 miRNAs identified as deregulated in ER+ compared to ER− breast tumors, 6 miRNAs are located in intragenic regions: miR-26a1 in CTDSPL, miR-342-5p in EVL, miR-30e in NFYC, miR-30c2 in OGFRL1, miR-26b in CTDSP1 and miR-1244 in PTMA. The expression levels of these 6 host genes were then measured, by RT-qPCR, in the validation series (Table 6). This evidence concerns the gene CTDSPL and breast neoplasm.
