Luteolin improves non-alcoholic fatty liver disease in db/db mice by inhibition of liver X receptor activation to down-regulate expression of sterol regulatory element binding protein 1c

In this study, we report that daily administration of luteolin for 8 weeks improved hepatic steatosis by repressing hepatic TG accumulation and increasing glycogen storage. Luteolin inhibited hepatic de novo lipid synthesis by regulating the LXR-SREBP-1c signaling pathway, which is over-activated in the livers of db/db mice. Further in vitro studies revealed that luteolin can competitively bind to the ligand binding domain to suppress the LXR...
