We downloaded LINC00184 expression level data in 348 cases of NSCLC tumour tissues and 46 cases of adjacent normal tissues from TCGA database; results showed that LINC00184 was significantly overexpressed in NSCLC tumour tissues compared to that in normal tissues (P < 0.01, Figure 1A). The gene discussed is LINC00184; the disease is non-small cell lung carcinoma.
