Determination of inbred obese mouse adipose tissue lipid profiles by high performance liquid chromatography

Başer, Tuğçe
Obesity becomes an important and serious health problem all over the world. Consumed too much calorie and less physical activity are the major issues in obesity. Obesity also causes some other important diseases such as hypertension, insulin resistance, dyslipidemia, type II diabetes and cardiovascular diseases. The aim of this study is to identify and quantify lipid profiles of obese Berlin Fat Mouse Inbred (BFMI) which has high fat content. These mouse lines showed spontaneous obesity. In addition to obesity, BFMI 860 and 861 had insulin resistance. Also, BFMI 860 and 861 lines were used as animal model for cardiovascular diseases. High performance liquid chromatography (HPLC) was used to separate, identify and quantify the lipids of BFMI mouse. Evaporative light scattering detector (ELSD) was used as detector with HPLC. Lipid extraction procedures were applied to BFMI. After that, HPLC were done with a gradient elution. Lipids that were identified and quantified were triglyceride (TG), diglyceride (DG), cholesterol (C), monoglyceride (MG) and phosphatidylcholin (PC). It is known that all of these lipids have role in cardiovascular diseases, insulin resistance and obesity. With respect to results, BFMI 860 and 861 mouse lines have more lipids especially TG, C, and MG than BFMI 852 and BFMI 856. Therefore, these lines are suitable for usage as animal models for obesity and type II diabetes.


Characterization of skeletal muscle lipids in obese mice lines
Aras, Ebru; Severcan, Feride; Department of Biology (2012)
Obesity becomes an epidemic health problem in developing and developed countries, which arises due to stable life style and increase in the consumption of high fat diets. Obesity is generally accompanied with various clinical disorders, such as insulin resistance, type II diabetes, hypertension, dyslipidemia and cardiovascular diseases. This study aims to characterize and quantify different lipid classes in longissimus dorsi (LD) and quadriceps (Q) skeletal muscles of control (DBA/2J), obese Berlin fat mous...
Investigation of the effects of long-term nocturnal feeding on blood leptin and lipids values, weight management, and behavior, in elderly wistar rats
Gönülkırmaz, Özlem; Jakubowska Doğru, Ewa; Department of Biology (2015)
Today, obesity is one of the most important health problems. For long, obesity has been linked to the diet type and daily caloric intake. The effect of time restricted feeding (TRF) on the weight management is less documented. The aim of this study was to investigate whether long-term night-time restricted feeding affects body weight gain, metabolic parameters, blood leptin levels, and behavioral performance in elderly overweight male Wistar rats. For 3 months (10 years in human), 14-months old, overweight ...
Investigation of effects of hyperlipidemia on IRE1α and insulin pathway in the cerebral cortex of ApoE-/- mice
AK, Deniz; Yanık, Tülin; Department of Molecular Biology and Genetics (2022-1-20)
Obesity prevalence increases worldwide. The most crucial reason for obesity is high-fat diet (HFD). Serum fatty acid levels are increased with HFD, inducing inflammation and glucose homeostasis disruption, leading to insulin signaling impairment linked to metabolic and neurodegenerative disorders in the brain. Glucose uptake of the cells is regulated by insulin through insulin receptor substrate (IRS) proteins, and disruption of this pathway results in insulin resistance. Hyperlipidemia, a lipid metabolism ...
Kas özellikleri ve obezite arasındaki ilişkinin genetik ve biyofiziksel yöntemlerle araştırılması
Severcan, Feride; Puralı, Nuhan; Banerjee, Sreeparna(2012)
Obesity, which arises from changes in lifestyle and feeding habits in developed and developing countries, is becoming a threat for human health due to its increasing prevelance. Especially, the increase in the consumption of high fat diets is one of the main factors that take role in the generation of obesity. Clinical disorders, such as type 2 diabetes, dislipidemia, cardiovascular diseases and hypertension, are all basic metabolic diseases in close relation with obesity. These metabolic disorders generall...
Evaluation of the effects of maltodextrin and microfluidization on the rheological and textural properties of cookie and cookie dough
Topaloğlu, Tuğçe; Yücel, Umut; Department of Food Engineering (2015)
Several health problems like diabetes and obesity are associated with consumption of highly fatty food, leading consumers to be more conscious about what they eat. This concern has been a driving factor for manufacturers to research and develop low- or reduced-fat products. Therefore, the baking industry finds new ways to respond to the demands. For this reason, fat replacement in bakery products has gained a popularity. Maltodextrin is commonly used to trim fat from bakery products because it gives some pr...
