OBJECTIVE Visfatin is a new novel proinflammatory adipocytokine affecting insulin resistance by binding to insulin receptor. To investigate whether visfatin stimulates monocyte chemotactic protein-1 (MCP-1) and interleukin-6 (IL-6) production in human umbilical vein endothelial cells (HUVEC) and mediates insulin receptor (IR) is involved in are not known. METHODS Cultured HUVEC was treated with different doses and durations of visfatin. Furthermore, HUVEC was pretreated with hydroxy-2-naphthalenylmethylphosphonic acid trisacetoxymethyl ester (HNMPA-(AM)3), a specific inhibitor of IR followed by visfatin (100 ng/ml) treatment. Enzyme-linked immunosorbent assay (ELISA) were used to measure MCP-1 and IL-6 production in HUVEC. Real-time quantitative reverse-transcription polymerase chain reaction (RT-PCR) was used for determining MCP-1 and IL-6 mRNA expression. RESULTS Visfatin significantly dose- and time- dependently up-regulated protein production of MCP-1 and IL-6 in HUVEC. We therefore found visfatin- induced MCP-1 and IL-6 production and gene expression in HUVEC were inhibited by HNMPA-(AM)3. CONCLUSIONS Visfatin induces endothelial MCP-1 and IL-6 production in HUVEC in a dose and time-dependently manner. This action appears to be mediated via insulin receptor pathway.

UI MeSH Term Description Entries
D011972 Receptor, Insulin A cell surface receptor for INSULIN. It comprises a tetramer of two alpha and two beta subunits which are derived from cleavage of a single precursor protein. The receptor contains an intrinsic TYROSINE KINASE domain that is located within the beta subunit. Activation of the receptor by INSULIN results in numerous metabolic changes including increased uptake of GLUCOSE into the liver, muscle, and ADIPOSE TISSUE.
