To detect the target of hsa‐miR‐132‐3p in BC, we used qPCR to investigate the expression of the candidate mRNAs in both 5637 and EJ‐m3 cells transfected with the hsa‐miR‐132‐3p inhibitor and found that Sox5 was the mRNA with the greatest increase in expression in cells transfected with the hsa‐miR‐132‐3p inhibitor (Figure 4A,B). This evidence concerns the gene SOX5 and breast cancer.
