In a microarray dataset for various breast cancer mouse models [36], Fzd7 and Fzd6 were highly expressed in C3(1)-Tag and Trp53-null ER-negative mammary tumors (S4 Fig), both of which represent mouse models for human basal-like/triple-negative breast cancers [37]. This evidence concerns the gene FZD6 and triple-negative breast carcinoma.
