ANP32B and breast carcinoma: Previously, we examined the relationship between ANP32B mRNA expression and breast cancer patient prognosis using information from three available data sets and reported that patients whose tumors showed the highest ANP32B mRNA levels had significant shorter survival.22 Here we performed Immunohistochemical staining (IHC) staining on 50 breast tumor tissues and the matched adjacent normal tissues, and found that breast tumor tissues presented higher ANP32B expression compared with adjacent normal tissues (Figures 5a and b).
