BRMS1 and breast cancer: Results of this meta-analysis suggested that the expression of BRMS1 protein in breast cancer tissues was significantly lower in comparison with normal tissues (OR = 0.08, 95%CI = 0.04–0.15, P < 0.001), while showing no significant difference in expression of BRMS1 mRNA between breast cancer and normal tissues (OR = −6.46, 95%CI = −17.27–4.34, P = 0.241) (Figure 1).
