Expression correlation analyses of WT1 with MYC/MMP2 in LUAD and LUSC cases using the Gene Expression Profiling Interactive Analysis 2.0 (GEPIA2) portal (http://gepia2.cancer-pku.cn/) and Tumour Immune Estimation Resource 2.0 (TIMER2.0) portal (http://timer.cistrome.org/) indicated that WT1 levels were obviously correlated with MMP2/MYC levels (Fig. 4C). The gene discussed is MYC; the disease is neoplasm.
