Regulatory network expression in mammary fat pad. Network analysis using differentially expressed genes (DEG) largely expressed (≥ 1.5-fold) in mammary fat pad (MFP) vs. parenchyma (PAR). The interactions shown involve the effect on expression (E), transcription (T), and protein-DNA interactions (PD) between transcription factors (blue background, white font) and other DEG largely expressed (≥ 1.5-fold) in MFP vs. PAR. Molecule types have their background highlighted as follows: enzymes, yellow; cytokines, red; growth factors, dark-green; membrane receptor, orange. Highlighted in dark-blue is THRSP, which is considered a key lipogenic transcription factor but IPA did not recognize it as such. The legend for the shape of the objects is reported in the figure. The intensity of the color in the object is proportional to the fold-difference in MFP vs. PAR.
