BRCA1 and breast carcinoma: Garcia et al. [38] interpreted their results that miR-146a overexpression inactivates BRCA1 in triple-negative breast cancers whereas Fkih M'hamed et al. [72] showed that BRCA1 expression in breast cancer lines MDA-MB-231 (triple-negative cell line) and MCF7 was not affected after transfection with miR-146a.
