Interestingly, the expression levels of PTGS2 (-4.80-fold change) and EGFR (-2.45-fold change) regulated by hsa-mirR128, ABCB1 (-2.21-fold change), IGF1 (-2.19-fold change), and IL6 (-2.85-fold change) regulated by hsa-miR-223, were significantly reduced in breast tumour tissue. The gene discussed is ABCB1; the disease is breast neoplasm.
