To gain a better perspective on Pax-5 transcript expression profiles from breast cancer cell lines, a collection of commonly used cell models from adenocarcinoma (i.e. MB415, MB436, and MB468), invasive ductal carcinoma (i.e. BT474, BT549, HCC1954, MCF7, MB231 and T47D) and non-cancerous (i.e. MCF10A and MCF12A) mammary cells were assessed for Pax-5 expression using RT-qPCR (Supplementary Table 1) [28]. This evidence concerns the gene PAX5 and invasive ductal breast carcinoma.
