title: Negative correlation between serum syndecan-1 and apolipoprotein A1 in patients with type 2 diabetes mellitus.
abstract: Heparan sulfate proteoglycans (HSPGs) are involved in the regulation of cell growth, apoptosis and lipid metabolism in vitro. Syndecans are the primary form of HSPGs. Syndecan-1 is involved in the processes of cell growth, differentiation, adhesion, wound healing and inflammation. Additionally, as a sinusoidal transmembrane HSPG facing the plasma compartment, syndecan-1 is a promising target to be involved in lipoprotein physiology. We aimed to examine the possible correlation of syndecan-1 and lipid profile in type 2 diabetes mellitus. In this study, serum syndecan-1 was detected by ELISA, and potential correlations between syndecan-1 and triglyceride, cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, lipoprotein a, apolipoprotein (apo) B, apoA1 and apoB/apoA1 were analyzed. Forty-one patients with type 2 diabetes and 31 age-matched, non-diabetic healthy subjects (controls) were enrolled. Syndecan-1 in patients with diabetes (26.15 ± 2.42 ng/ml) was significantly higher than that of the controls (16.85 ± 1.98 ng/ml, t = -2.98, P = 0.005). Serum syndecan-1 level correlated negatively with apoA1 (r = -0.46, P = 0.003). Multiple regression analysis showed that apoA1 (b = -0.43, P = 0.003) was a predictor of serum syndecan-1 levels in subjects with type 2 diabetes.
