Chondroitin sulfate-rich proteoglycans secreted by arterial intima smooth muscle cells appear involved in low density lipoprotein entrapment and modification. Hypothetically, such a process may contribute to atherogenesis. We compared composition and size of those proteoglycans synthesized by proliferating and resting human arterial smooth muscle cells for(More)
OBJECTIVE To investigate the relationship of inflammation and endothelial activation with insulin resistance and adiposity in type 2 diabetes. METHODS AND RESULTS Hundred and thirty-four (45 female) type 2 diabetic subjects aged 50-75 in the Fenofibrate Intervention and Event Lowering in Diabetes Study in Helsinki were examined before fenofibrate(More)
OBJECTIVE We investigated the potential role of ADAMTS-1 (a disintegrin and metalloprotease with thrombospondin motif type I) in atherogenesis. METHODS AND RESULTS ADAMTS-1 is expressed at the highest levels in the aorta when compared with other human tissues examined. Immunolocalization studies in human aorta and coronary artery indicate that ADAMTS-1(More)
Recent prospective analysis identified secretory phospholipase A(2)-IIa (sPLA(2)IIa) as a coronary artery disease (CAD) risk predictor. This study aimed to examine the relationship between serum levels of sPLA(2)IIa and variation in the sPLA(2)IIa gene (PLA2G2A) in a cohort of patients with Type II diabetes (T2D) mellitus. Six tagging single nucleotide(More)
Increased expression of secretory non-pancreatic phospholipase A(2) (sPLA(2)-IIA) could be part of the inflammatory reaction in atherosclerosis. However, the factors controlling sPLA(2)-IIA production in human vascular cells are unknown. We investigated regulation of sPLA(2)-IIA expression and secretion by human arterial smooth muscle cells in culture(More)
Secretory phospholipase A(2) (PLA(2)) can be proatherogenic both in the circulation and in the arterial wall. In blood plasma, PLA(2) can modify the circulating lipoproteins and so induce formation of small dense LDL particles, which are associated with increased risk for cardiovascular disease. In the arterial wall, PLA(2) can hydrolyze lipoproteins. The(More)
Animal and human studies suggest that both secretory PLA2 (sPLA2)-V and sPLA2-IIA (encoded, respectively, by the neighbouring PLA2G5 and PLA2G2A genes) contribute to atherogenesis. Elevated plasma sPLA2-IIA predicts coronary heart disease (CHD) risk, but no mass assay for sPLA2-V is available. We previously reported that tagging single nucleotide(More)
Retention of apo B-100 lipoproteins, low density lipoprotein (LDL) and probably lipoprotein(a), Lp(a), by intima proteoglycans (PGs) appears to increase the residence time needed for their structural, hydrolytic and oxidative modifications. If the rate of LDL entry exceeds the tissue capacity to eliminate the modified products, this process may be a(More)
OBJECTIVES The objective of this study was to assess the relationship between inflammation, endothelial activation and incipient atherosclerosis in type 2 diabetes. DESIGN Cross-sectional study. Setting and subjects. We studied 239 type 2 diabetic patients [71 with clinical cardiovascular disease (CVD)] and 78 healthy control subjects, aged 50-75 in a(More)
There is evidence for the presence of lysophosphatidylcholine (lysoPC) in oxidatively modified low density lipoprotein, human plasma and in atherosclerotic lesions. We studied the effect of lysoPC on the cytokine production by human monocytes. Among all the cytokines tested (IL-8, TNF alpha, MCP-1 and IL-1beta), we found that lysoPC most consistently(More)
