PPARγ1 ChIP analysis in MCF10A-NeuT mammary tumors showed the number of sites bound by PPARγ1 Wt including all cis elements was comparable to the ~23,000 and ~21,000 sites identified in human adipocyte cell lines [88], but fewer than the ~40,000 sites identified in primary in vitro differentiated human adipose derived stem cells. Here, PPARG is linked to breast cancer.
