M6 cells expression a similar genetic signature as the parent tumor, C3(1)Tag tumor. The mammary tumors, and tumor cell line, are distinct from normal mammary epithelial tissue (FVB) BRCA/p53, cmyc, h2n, p53ERneg, p53ERpos, pymt and ras samples were not reported in this paper.
Overall design
We used microarrays to determine whether the M6 cell line retains the SV40Tag signature (91 gene signature) that is expressed in C3(1)Tag tumors but not FVB normal mammary tissue.
