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). Here, TGFB1 is linked to neoplasm.
