TRAF6 and breast carcinoma: Data are summarized in Fig 4A clearly showing that the expression levels of Myd88, TRAF6 and TRIF were markedly lower in M13SV1-EGFP-Neo breast epithelial cells as compared to MDA-MB-435-Hyg breast cancer cells and M13MDA435-1 and -3 hybrid cells (Fig 4A), which is further in accordance that a nuclear translocation of NF-κB was not observed in LPS treated (100ng/ml, 2h) M13SV1-EGFP-Neo breast epithelial cells (Fig 4B).
