MIR31HG and non-small cell lung carcinoma: MIR31HG was a LncRNA, identified as >2166 nucleotides in length.76 Recent studies showed that increased MIR31HG expression increased gefitinib resistance in NSCLC lines through the EGFR/PI3K/AKT signalling pathway.77 Zheng et al also discovered MIR31HG could promote the invasion of NSCLC by activating the Wnt/β‐catenin signalling pathway.78
