ABCA1 expression was shown to be regulated by miR‐96 in breast cancer cell lines (Moazzeni et al., 2017) and AGTR1 was suggested to be a marker of resistance to neoadjuvant chemotherapy in HER2− breast cancer (de Ronde et al., 2013), whereas it was shown to be a therapeutic target in ER+ and ERBB2− breast cases (Ateeq et al., 2009). The gene discussed is ESR1; the disease is breast carcinoma.
