Consistent with statistical analysis of the public databases, we found that MRPL12, MRPL13 and POP1 were over-expressed in most of the TNBC-tissues than their para-carcinoma specimens, and be more abundant in the differentiated and metastatic breast cancer cell lines (such as MCF10Ca1a, 231-HM and 231-BO). Here, MRPL13 is linked to carcinoma.
