Expression of the lipogenic transcription factors Liver X receptor alpha (LXRa/Nr1h3), carbohydrate-responsive element-binding protein isoforms (Mlxipla and Mlxiplb), sterol regulatory element-binding protein 1 isoforms (Srebf1a and Srebf1c), and its target fatty acid synthase (Fasn) were similarly expressed in Plin4+/+ and Plin4−/− mice fed CD or WD. The gene discussed is SREBF1; the disease is Wilson disease.
