The genes, MMP2, TIMP1, TIMP2, TGFβ1, Ki-67, NRAS, and ARAF exhibited identical expression between BC and normal tissue; whereas MMP9, FGF2, p14ARF, p16INK4A, EGFR, EGF and BRAF showed significantly lower expression in BC vs. normal tissue (Table S2). The gene discussed is BRAF; the disease is breast cancer.
