| 1 | Insulin-mimetic compound hexaquis(benzylammonium) decavanadate is antilipolytic in human fat cells显示文摘AIM To assess in rodent and human adipocytes the antilipolytic capacity of hexaquis(benzylammonium) decavanadate(B6V10), previously shown to exert antidiabetic effects in rodent models, such as lowering free fatty acids(FFA) and glucose circulating levels.METHODS Adipose tissue(AT) samples were obtained after informed consent from overweight women undergoing plastic surgery. Comparison of the effects of B6V10 and reference antilipolytic agents(insulin,benzylamine,vanadate) on the lipolytic activity was performed on adipocytes freshly isolated from rat, mouse and human AT. Glycerol release was measured using colorimetric assay as an index of lipolytic activity. The influence of B6V10 and reference agents on glucose transport into human fat cells was determined using the radiolabelled 2-deoxyglucose uptake assay.RESULTS In all the species studied, B6V10 exhibited a dosedependent inhibition of adipocyte lipolysis when triglyceride breakdown was moderately enhanced by β-adrenergic receptor stimulation. B6V10 exerted on human adipocyte a maximal lipolysis inhibition of glycerol release that was stronger than that elicited by insulin. However, B6V10 did not inhibit basal and maximally stimulated lipolysis. When incubated at dose ≥ 10 μmol/L, B6V10 stimulated by twofold the glucose uptake in human fat cells, but-similarly to benzylamine-without reaching the maximal effect of insulin, while it reproduced one-half of the insulin-stimulation of lipogenesis in mouse fat cells. CONCLUSION B6V10 exerts insulin-like actions in adipocytes, including lipolysis inhibition and glucose transport activation. B6V10 may be useful in limiting lipotoxicity related to obesity and insulin resistance. | Christian Carpéné Silvia Garcia-Vicente Marta Serrano Luc Marti ChloéBelles Miriam Royo Jean Galitzky Antonio Zorzano Xavier Testar | 2017 | World Journal of Diabetes2017，8，4： | 2 |
