To date, related studies have found abnormal expression of miR‐34a in a variety of tumors and cell lines, including neuroblastoma, lung cancer, and melanoma cell lines.20, 21, 22, 23 We found that Axl was a potential target of miR‐34a using Target Scan bioinformatics software, and further double luciferase reporter gene assays revealed that Axl was targeted by miR‐34a. The gene discussed is AXL; the disease is lung carcinoma.
