RBM38 expression was positively correlated 1 with PTEN in breast cancer tissues. a Immunohistochemistry analysis of PTEN and RBM38 in breast cancer tissue at 200 × magnification. RBM38 was mainly expressed in cytoplasm and PTEN was expressed in the cytoplasm and nucleus. The arrow showed the location of RBM38 and PTEN. b Representative images of moderate and the relative RBM38 staining in PTEN positive and negative breast cancer tissues
