Reduced apolipoprotein glycosylation in patients with the metabolic syndrome.

ABSTRACT:

Objective

The purpose of this study was to compare the apolipoprotein composition of the three major lipoprotein classes in patients with metabolic syndrome to healthy controls.

Methods

Very low density (VLDL), intermediate/low density (IDL/LDL, hereafter LDL), and high density lipoproteins (HDL) fractions were isolated from plasma of 56 metabolic syndrome subjects and from 14 age-sex matched healthy volunteers. The apolipoprotein content of fractions was analyzed by one-dimensional (1D) gel electrophoresis with confirmation by a combination of mass spectrometry and biochemical assays.

Results

Metabolic syndrome patients differed from healthy controls in the following ways: (1) total plasma--apoA1 was lower, whereas apoB, apoC2, apoC3, and apoE were higher; (2) VLDL--
