Subsequently, we used TCGA BRCA data to analyze the expression levels of miR-934 in patients with triple-negative breast cancer and its associated target mRNAs (PTEN, EGR2, ANK3, ZBTB16, TCF3, CCNG1, FOSL2, BTG1, HMGA2, TP53AIP1, and INSIG1) and found that the overexpression of miR-934 significantly discriminates triple-negative molecular subtype from normal breast tissue (Figure 6C). The gene discussed is EGR2; the disease is triple-negative breast carcinoma.
