MED15 and neoplasm: The paired-samples t-test did not detect significant differences between tumoral versus control ΔCt values of CD16 (P = 0.772), CD57 (P = 0.157), TGF-β1 (P = 0.947), and MED15 (P = 0.244): None of the relative expressions of the four evaluated genes leaned towards an overall overexpression or underexpression in the tumor compared to the adjacent healthy tissue (Fig. 1, Table 1).
