Another interesting potential therapeutic implication of the REV-ERB agonist SR9011 was investigated in breast cancer models based on the molecule’s structural similarity with the v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2 (ERBB2) gene, also known as human epidermal growth factor receptor 2 (HER2), which is often mutated in breast cancer [60]. The gene discussed is ERBB2; the disease is breast carcinoma.
