We explored the mechanism by which lncRNA PTTG3P regulated MAP2K6 and E2F1 through binding with ILF3, by first doing correlation analysis that showed that E2F1 or MAP2K6 expression levels were positively correlated with ILF3 expression levels in NSCLC tissues from TCGA and/or GTEx data provided by GEPIA (http://GEPIA.cancer-pku.cn/index.html) (Fig. 5H). Here, E2F1 is linked to non-small cell lung carcinoma.
