- W1996326507 abstract "ATP binding cassette transporter A1 (ABCA1) is a member of the ATP-binding cassette transporter family. It plays an essential role in mediating the efflux of excess cholesterol. It is known that peroxisome proliferator-activated receptor gamma (PPARγ) promoted ABCA1 expression. We previously found 7-ketocholesteryl-9-carboxynonanoate (oxLig-1) upregulated ABCA1 partially through CD36 mediated signals. In the present study, we intended to test if PPARγ signally is involved in the upregulation mediated by oxLig-1.First, we docked oxLig-1 and the ligand-binding domain (LBD) of PPARγ by using AutoDock 3.05 and subsequently confirmed the binding by ELISA assay. Western blotting analyses showed that oxLig-1 induces liver X receptor alpha (LXRα), PPARγ and consequently ABCA1 expression. Furthermore, oxLig-1 significantly enhanced ApoA-I-mediated cholesterol efflux. Pretreatment with an inhibitor for PPARγ (GW9662) or/and LXRα (GGPP) attenuated oxLig-1-induced ABCA1 expression. Under PPARγ knockdown by using PPARγ-shRNA, oxLig-1-induced ABCA1 expression and cholesterol efflux in THP-1 macrophages was blocked by 62% and 25% respectively.These observations suggest that oxLig-1 is a novel PPARγ agonist, promoting ApoA-I-mediated cholesterol efflux from THP-1 macrophages by increasing ABCA1 expression via induction of PPARγ." @default.
