Importantly, consistent with the tissue microarray (TMA) analysis presented here, there is a significant correlation between high WNT7A gene expression and poor outcome (distant metastasis-free survival) in breast cancer patients, either when examining all systemically untreated breast cancers (log-rank P=0.0382; Fig. 8g) or only the basal breast cancers (log-rank, P=0.0427; Fig. 8h). This evidence concerns the gene WNT7A and breast carcinoma.
