The expression of 6831 imageable genes differs in various cancer types and their tissue of origin, and correlates with overall survival in univariate and multivariate analyses (Supplementary Data 30), including the Cholinergic Receptor CHRNA7 in cervix cancer, the Nitric Oxide Synthase NOS2 in colon cancer, and the Epoxide Hydrolase EPHX3 in Hepatocellular cancer (Fig. 5e(i, ii)). The gene discussed is EPHX3; the disease is colonic neoplasm.
