Figure 1. Immunohistochemical findings of low RNA-binding motif protein 3 (RBM3) nuclear expression (RBM3≤4). (A, B) No expression of RBM3 in poorly differentiated invasive ductal carcinomas. (C) Weakly expressed RBM3 in invasive micropapillary carcinoma. (D) No expression of RBM3 in moderately differentiated invasive ductal carcinoma (immunohistochemistry for RBM3, ×200).
