CCNE1 and neoplasm: In order to test the oncogenic activity of LINC01116, miR‐9‐5p and CCNE1 in vivo, LUAD cells stably expressing sh‐LINC01116 and overexpressing miR‐9‐5p or CCNE1 stably were subcutaneously injected into the subcutaneous tissue of nude mice, establishing the xenograft tumour model.
