EGF and breast cancer: Interestingly, no significant differences were detected between the breast cancer cases and the carriers for the expression of 11 different genes:, ADAM23 (p = 0.343), BCL2 (0.213), EGF (p = 0.90), CDKN1A (p = 0.567), CTSD (0.397), GSTP1 (0.186), MAPK3 (p = 0.058), MGMT (p = 0.165), MMP9 (p = 0.463), TGFB1 (p = 0.084) and TP53 (p = 0.334) (Figure 4B).
