To further study which miRNA regulated NFATc1 expression, we predicted several miRNAs including miR‐143, miR‐124, miR‐338, miR‐137, and miR‐218 by online database TargetScan 7.2, and these five miRNAs acted as tumor suppressor in lung cancer. The gene discussed is NFATC1; the disease is lung cancer.
