BACKGROUND Chemokine is important in the initiation and progression of atherosclerosis, the clinically manifest stages of atherosclerosis and acute coronary syndrome. Vitamin D deficiency has been reportedly linked with hypertension and myocardial infarction, as well as other cardiovascular-related diseases, such as congestive heart failure, peripheral vascular disease and atherosclerosis. Mono...

Human monocytic cell line THP-1 incubated with as little as 10 ng/ml of phorbol myristate acetate bound and metabolized 1-2 micrograms of Ac-LDL over a 5-h period. In the absence of phorbol treatment, no specific metabolism of Ac-LDL occurred. Optimal levels of receptor were reached after 72 h of exposure. Induction of receptor was dependent on protein and RNA synthesis and was partially revers...

Chemokines such as the monocyte chemol attractant protein-1 (MCP-1) convert monocyte rolling to firm arrest under physiological flow conditions via integrin activation and simultaneously activate phosphoinositide 3-kinase (PI3K). Here we used adenoviral gene transfer and biochemical inhibitors to manipulate PI3K-dependent pathways in human monocytes. In in vitro lipid kinase assays from purifie...
