In addition, analysis of publicly available RNAseq data sets from The Cancer Genome Atlas (TCGA) revealed that EGR4 was up-regulated (more than 2-fold) in 17 of 39 lung adenocarcinoma cases (Figure S4A), and in 19 of 46 squamous cell carcinoma (SCC) cases (Figure S4B) compared with their corresponding normal lung. This evidence concerns the gene EGR4 and squamous cell carcinoma.
