The down-regulation of ADARB1 may be related to the pathogenesis of non-small cell lung cancer (Wang et al., 2019; Wang et al., 2020), and low levels of ADARB1 in lung cancer are correlated with shorter first progression (FP), overall survival time (OS) and post-progression survival time (PPS). The gene discussed is ADARB1; the disease is lung cancer.
