We found a very significant correlation of PBOV1 expression to FOXA2 expression levels in the GDS1746 [37] prostate cancer dataset (correlation 0.73, p = 2•10−5, 0.2th percentile), in GOBO pooled breast cancer dataset [34] (correlation 0.145, p = 2•10−7, 7th percentile, but no significant correlation was present in GDS806 breast cancer dataset. The gene discussed is FOXA2; the disease is breast carcinoma.
