This is in agreement with previous studies showing an inverse relationship between Nrf2 expression pattern and miR-28 in breast carcinoma cell lines [50], miR-93 within rat models of breast carcinogenesis [86] and miR-153 in breast cancer cell lines [51], neuroblastoma cells [52,53] and glioma stem cells [54]. This evidence concerns the gene NFE2L2 and breast cancer.
