NR4A3 has been shown to regulate cell proliferation, apoptosis and migration and have generally tumour‐suppressive roles in breast cancer, lung cancer, gastric cancer and leukaemia.36, 37, 46 Therefore, we hypothesized that the tumour suppressor NR4A3 may mediate the oncogenic roles of LINC00467 in HCC. The gene discussed is LINC00467; the disease is breast cancer.
