Additionally, expression of BRMS1 protein in the three types of breast cancer tissues was all lower than the normal tissues (ductal carcinoma: OR = 0.10, 95%CI = 0.04–0.22, P < 0.001; lobular carcinoma: OR = 0.09, 95%CI = 0.04–0.23; P < 0.001; medullary carcinoma: OR = 0.02, 95%CI = 0.00–0.12, P < 0.001) (Figure 3). Here, BRMS1 is linked to breast cancer.
