FABP4 and skin basal cell carcinoma: The nuclear receptor Nur77 is a transcription factor encoded by the immediate early gene Nr4a1 (nuclear receptor subfamily 4 group A member 1), Nur77 interacts with the promoters of CD36 and fatty acid binding protein 4 (FABP4) and inhibits their transcription, thereby hindering fatty acid uptake and inhibiting cell proliferation, and BCC proliferation was accelerated in Nur77 knockdown.13
