Meanwhile, EGFR (p = 0.008), RAC1 (p = 0.03) and VEGF-B (p = 0.0004) genes expression in mammary carcinoma tissue were higher in the high proliferation index group (≥14%) than in low proliferation index group (<14%) (Supplementary Figure S6). The gene discussed is EGFR; the disease is breast carcinoma.
