We found that the expression of EZH2 is positively correlated with KRAS (r = 0.3167 and p < 0.001) and BRAF (r = 0.2397and p < 0.0001) gene expression in lung squamous cell carcinoma and lung adenocarcinoma (Figures 5(a) and 5(g)). The gene discussed is BRAF; the disease is squamous cell lung carcinoma.
