These results showed that CCNE1, CEP55, ANLN, hsa-miR-592, hsa-miR-141-3p, hsa_circ_0000069, hsa_circ_0000518, and has_circ_0000520 were upregulated in BRCA tumor tissues compared to adjacent nontumor tissues, while ADIPOQ, hsa-miR-195-5p, hsa-miR-204-5p, and has_circ_0000977 were downregulated in BRCA tumor tissues (Figure 9). Here, CCNE1 is linked to invasive breast carcinoma.
