MET and TGFBR2 gene expressions were found to positively correlate in several other tumor entities, such as prostate adenocarcinoma, thymoma, glioblastoma, head and neck squamous cell carcinoma, testicular germ cell tumors, and esophageal carcinoma (Fig. S3D–I). The gene discussed is TGFBR2; the disease is head and neck squamous cell carcinoma.
