Previous studies have shown that lncRNA BCAR4 was overexpressed in several types of tumors and act as an oncogene in tumors.[29–32] Godinho et al[11] indicated that lncRNA BCAR4 contributed to breast tumor aggression and tamoxifen resistance by regulating the ERBB2/ERBB3 signaling pathways. The gene discussed is ERBB2; the disease is breast neoplasm.
