Abstract

The non-enzymatic CARBAMYLATION of low density lipoprotein (LDL) is a naturally occurring chemical modification of apolipoprotein B as a result of condensation between lysine residues and cyanate derived from urea. Carbamylated LDL is poorly recognized by LDL receptors and initiates different processes that can be considered proatherogenic. Thus, LDL CARBAMYLATION may contribute to the increased risk of atherosclerosis in patients with kidney failure. The objective of this study was to investigate in vitro effects of FLAVONOIDS on LDL CARBAMYLATION. LDL was isolated from plasma using ultracentrifuge technique with a single step discontinuous gradient. Then, cyanate was added to LDL and LDL CARBAMYLATION level was estimated in absence and presence of FLAVONOIDS by a colorimetric method at 530 nm. The results of this study showed that a number of FLAVONOIDS including rutin, catechin, morin, myricetin, kaempferol, taxifolin, luteolin, naringin and quercetin decreased LDL CARBAMYLATION in a dose dependent manner. Also, it was demonstrated that these nutrients decreased ELECTROPHORETIC MOBILITY of carbamylated LDL. Based on the results obtained in this study, it is suggested that FLAVONOIDS are able to inhibit LDL CARBAMYLATION (probably by scavenging cyanate ions) and thus, may have a role in ameliorating atherosclerotic risk of patients with kidney failure.
