Abstract (english)
Insulin resistance is a common phenomenon in obesity and Type 2 diabetes. Common factor important for development of diabetes and insulin resistance is intake of saturated fat. Vanadate treatment improves glucose homeostasis in vivo. The aim of this study was to find out changing of hepatic glucose output in dependence of saturated fat diet and possible direct action of vanadate in cultured hepatocytes. Hepatocytes were isolated by a collagenase perfusion technique and cultured for 24 h in M 199 serum-free medium. The glucose production in hepatocytes isolated from rats on high saturated fat diet was significantly 139% higher comparable to standard controls. Glucagon 100% increased glucose production in hepatocytes from rats on standard diet and 200% in hepatocytes on saturated high fat diet. The addition vanadate significantly decreased basic glucose production and did not influence glucagon stimulated glucose production. Presence of insulin did not influence either glucagon or vanadate effect. High saturated fat diet not only increases insulin resistance but also decreases chances of successful therapy of diabetes.
Abstract (croatian)
Inzulinska rezistencija je zajednički fenomen koji se pojavljuje u pretilosti i dijabetesu tipa 2. Zajednički faktor koji je važan za razvoj dijabetesa i inzulinske rezistencije je uzimanje zasićenih masti. Vanadate poboljšava glukoznu homeostazu in vivo. Svrha ovog rada je otkriti promjene jetrenog stvaranja i otpuštanja glukoze u ovisnosti o dijeti bogatoj zasićenim mastima i moguće direktno djelovanje vanadate u kultiviranim hepatocitima. Hepatociti su izolirani pomoću kolagenaze i kultivirani 24 sata u M 199 mediju bez dodatka seruma. Stvaranje glukoze u hepatocitima izoliranim iz štakora na visoko masnoj dijeti bogatoj zasićenim masnoćama bilo je 139% veća u usporedbi s standardnom kontrolom. Glukagon 100% povećava proizvodnju glukoze u hepatocitima dobivenim iz štakora na standardnoj dijeti, a 200% u štakora na dijeti sa zasićenim masnoćama. Vanadate je signifikantno smanjio bazičnu proizvodnju glukoze, a nije utjecao na glukagonom stimuliranu produkciju glukoze. Prisutnost inzulina nije utjecala na glukagonski kao ni na vanadate efekt. Dijeta bogata zasićenim masnoćama ne povećava samo inzulinsku rezistenciju nego također smanjuje izglede za uspješno liječenje dijabetesa.
