High-fat Diet Increases Islet Size in Male but not Female Mice We then wanted to investigate if the established hyperinsulinemia had resulted in compensations at the level of islets of Langerhans. September 25, Copyright: The mean value of three images per adipose tissue depot was used in one observation. The aim of the study was to pinpoint the mechanisms resulting in different outcome of female and male mice on a high-fat diet HFD. After a minute resting period, blood flow measurements were performed using a microsphere technique as previously described [26]. In the current study, sex differences during onset of metabolic syndrome were investigated in female and male mice fed a high fat diet, with particular focus on adipose tissue inflammation and islet dysfunction. The total number of islets and the total number of perfused islets were counted. Low-grade, systemic inflammation was absent in obese female but present in obese male mice IL-6 and mKC, males: June 14, ; Accepted: All slides were co-stained with Hoechst Invitrogen, Stockholm, Sweden. Competing interests: The pancreatic weight was found to be higher in male mice than in female mice irrespective of diet Figure 3A. Results Sex Differences in Development of Hyperinsulinemia and Insulin Resistance Despite Similar Weight Gain after High-fat Diet High-fat diet was used to induce metabolic syndrome, and firstly the stage of the disorder had to be defined. Animals were tracheostomized to facilitate respiration. Instead, the mean islet diameter in the sections was increased in the high-fat-fed male mice compared to all other groups, which suggest that these islets become hypertrophic in response to HFD Figure 3D.

This observation was not due to increased islet number, as the total number of islets in the groups did not differ between sexes or diets Figure 3C. Mice fed control or HFD were monitored for weight, blood glucose, and insulin for 14 weeks. Estrogens, the major female sex hormone, are suggested to protect against development of the metabolic syndrome, and the prevalence of obesity, insulin resistance, and type 2 diabetes increases in post-menopausal women [19]. Further, only male mice on HFD showed impaired insulin tolerance 30 and 60 minutes after an ITT compared to all other groups Figure 2D , consistent with established insulin resistance in male but not female mice. Figures Abstract Sex differences in obesity-induced complications such as type 2 diabetes have been reported. Fat nylon sex



The fraction of islets was increased in male mice after HFD when compared to high-fat-fed female mice, whereas no differences were seen between the control-fed animals Figure 3B. June 14, ; Accepted: Blood Flow Measurements Mice were anesthetized by intraperitoneal injections of avertin 2. Sex differences on chemokine production, down-stream metabolic changes and effects on adipose tissue during obesity are not fully established. Mice fed control or HFD were monitored for weight, blood glucose, and insulin for 14 weeks. Despite similar weight Male mice also exhibited hypertrophic islets with intact function in terms of insulin release and blood perfusion. Further, only male mice on HFD showed impaired insulin tolerance 30 and 60 minutes after an ITT compared to all other groups Figure 2D , consistent with established insulin resistance in male but not female mice. Circulating chemokines, islet endocrine function and blood flow, as well as adipose tissue populations of macrophages and regulatory T-lymphocytes Treg were thereafter assessed. Regulatory T-cell Content in Visceral Adipose Tissues The stromal vascular fraction of gonadal and mesenteric adipose tissue was isolated from female and male mice fed a control or HFD. After 14 weeks of HFD, the glucose tolerance was impaired compared to age-matched control mice. The pancreatic weight was found to be higher in male mice than in female mice irrespective of diet Figure 3A. Competing interests: Plasma glucose concentrations were measured in blood from the tail using test reagent strips detection range 1. In addition, hyperinsulinemia consistent with insulin resistance was detected in high-fat-fed male mice, whereas female mice on HFD had normal serum insulin concentrations despite a similar increase in body weight as the male mice on HFD Figure 2C. The fractional islet mass was estimated using a grid and islet diameter was measured using ImageJ rsbweb. August 28, ; Published:

Results Sex Differences in Development of Hyperinsulinemia and Insulin Resistance Despite Similar Weight Gain after High-fat Diet High-fat diet was used to induce metabolic syndrome, and firstly the stage of the disorder had to be defined. In addition, different studies indicate that estrogens may have pro- as well as anti-inflammatory effects [22]. Regulatory T-cell Content in Visceral Adipose Tissues The stromal vascular fraction of gonadal and mesenteric adipose tissue was isolated from female and male mice fed a control or HFD. Estrogens, the major female sex hormone, are suggested to protect against development of the metabolic syndrome, and the prevalence of obesity, insulin resistance, and type 2 diabetes increases in post-menopausal women [19]. During the first hour islets were incubated in 1. The pancreatic weight was found to be higher in male mice than in female mice irrespective of diet Figure 3A.

Plasma glucose concentrations increased in high-fat-fed male mice over time compared to mice on control diet, whereas plasma glucose levels of high-fat-fed female mice remained constant Figure 2A. The total number of islets and the total number of perfused islets were counted. The exact withdrawal rate was confirmed by weighing the sample. High-fat Diet Increases Islet Size in Male but not Female Mice We then wanted to investigate if the established hyperinsulinemia had resulted in compensations at the level of islets of Langerhans. However, conflicting data on circulating levels of inflammatory markers in women and men during normal conditions and various diseases have been presented, and the concentrations of pro-inflammatory IL-6 have been shown to be higher in men than women, but also opposite data exist [6] , [20] , [21]. Increased islet blood perfusion most likely results in amplified shear stress on intra-islet endothelium due to the concomitant capillary hypertension [11] , which, if persisting for longer periods, is believed to contribute to impairment of islet function [12]. In contrast, the anti-inflammatory Treg cell population increased in the adipose tissue of female mice in response to weight gain, while the number decreased in high-fat-fed male mice. Obvious sex differences in the susceptibility to various diseases have been detected, even though the reasons for this are not completely clear.

Despite similar weight The authors have declared that no competing interests exist. All slides were co-stained with Hoechst Invitrogen, Stockholm, Sweden. Figures Abstract Sex differences in obesity-induced complications such as type 2 diabetes have been reported. The inflammatory markers originate from both adipocytes and inflammatory macrophages infiltrating the expanding adipose tissue [7] , and induce pro-inflammatory transcription factors which interfere with the systemic actions of insulin, resulting in peripheral insulin resistance [8].
