Survival analysis using the Kaplan Meier (KM) plotter for lung adenocarcinoma showed that high expression of CDK9, SOX2, SOX9, and MCL1 (MCL1 survival curve is not shown) was significantly associated with worse survival in the patients (OS, CDK9: p = 0.00029; SOX2: p = 0.0017; SOX9: p = 0.048; MCL1: p = 0.00016) (Figure 8D–F) [68]. This evidence concerns the gene SOX2 and lung adenocarcinoma.
