Similar to the mouse mammary gland correlation analysis, group 3 is very strongly enriched for cell cycle/proliferation and DNA-damage response-related genes and is anti-correlated to the NR2F1-containing cluster (Table S6), suggesting that also in human breast cancer low NR2F1 transcript levels are associated with an increase in cell cycle-related gene expression. This evidence concerns the gene NR2F1 and breast carcinoma.
