NR2F1 and breast carcinoma: From the 59 genes with strongest anti-correlation (r<−0.3) to NR2F1 in the human breast cancer data set, 41 (69%) were also found to be among the strongest anti-correlated (r<−0.3) to Nr2f1 in the mouse MG data set, which is 2-fold enrichment in comparison to strongly anti-correlated genes (r<−0.3) to Nr2f1 in the entire mouse data set (34%).
