PG - 1061-8 LID - 10.1177/1470320313518252 [doi] AB - AIM: To investigate the effect of telmisartan on the lipometabolisms and the proinflammatory factors secreted from 3T3-L1 adipocytes and to explore the possible mechanisms. MATERIALS AND METHODS: Telmisartan was applied to interfere with mature 3T3-L1 adipocytes. The culture's free fatty acids, interleukin 6 (IL-6) and tumor necrosis factor alpha (TNFalpha) were evaluated. Oil Red O staining was used to determine the adipogenesis of 3T3-L1 adipocytes. (18)F-FDG uptake levels corrected for protein content were determined by cellular radioactivity. The total RNA was isolated for hybridization experimentation in the microarray. RESULTS: Telmisartan reduced lipid storage and increased (18)F-FDG uptake in a dose-dependent manner, reduced the levels of IL-6 and TNFalpha and increased those of free fatty acids. One hundred and fifty-seven differentially expressed genes were found by microarray. The mitogen-activated protein kinase (MAPK) signaling pathway involved in the secretion of proinflammatory factor and lipid metabolisms was affected by telmisartan. The expression of endothelial nitric oxide synthetase gene 3 (Nos3) and carnitine palmitoyl transferase 1alpha (CPT1alpha) was up-regulated by telmisartan. CONCLUSIONS: Telmisartan affected lipometabolisms and the proinflammatory factors secreted from adipocytes. Nos3, CPT1alpha and the MAPK pathway being affected by telmisartan may be the underlying cause of the improvement in lipid metabolisms and secretion of proinflammatory factors of differentiated 3T3-L1 adipocytes.
