Using the online tool DriverDBv3 (http://driverdb.tms.cmu.edu.tw/), whose data source is TCGA, TXN2 expression was found enhanced in LUSC (lung squamous cell carcinoma) but not in LUAD (lung adenocarcinoma), compared to lung normal tissue (Figure 4A,B). The gene discussed is TXN2; the disease is squamous cell lung carcinoma.
