Guggulsterone enhances glycosylated low density lipoprotein binding in rat liver.

Modification of low density lipoprotein by nonenzymic glycosylation resulted in decreased receptor-mediated lipoprotein catabolism. Guggulsterone treatment caused significant increase in binding of [125I] low density lipoprotein as well as [125I] glycosylated low density lipoprotein. Scatchard plot analysis of the binding activity revealed that under the influence of guggulsterone, the liver membrane contains increased amounts of a functional lipoprotein receptor that binds more low density lipoprotein particles.
