Pregnancy-induced metabolic changes are regulated by signals from an expanded adipose organ. Placental growth factor (PlGF), acting through vascular endothelial growth factor receptor-1, may be among those signals. There is a steep rise in circulating PlGF during normal pregnancy, which is repressed in gravidas who develop preeclampsia. PlGF-deficiency in(More)
To evaluate the hypothesis that the clock gene Bmal1 (brain and muscle arnt like protein-1) plays a role in the development of obesity, 5-week-old male Bmal1-deficient (Bmal1(-/-)) mice and wild-type littermates (Bmal1(+/+)) were kept on a high-fat diet (HFD) for 15 weeks. Despite an initial accelerated weight gain of Bmal1(-/-) mice, body weight and(More)
Rosiglitazone ((RS)-5-[4-(2-[methyl(pyridin-2-yl)amino]ethoxy)benzyl]thiazolidine-2,4-dione, RGZ)-induced adverse drug effects in diabetic patients were not adequately predicted by current preclinical rodent models. Therefore, we have used the Akita mouse with genetic predisposition to diabetes to unravel the underlying molecular mechanisms. The effect of(More)
To investigate the chronic effect of sitagliptin (7-[(3R)-3-amino-1-oxo-4-(2,4,5-trifluorophenyl)butyl]-5,6,7,8-tetrahydro-(3-(trifluoromethyl)-1,2,4-triazolo[4,3-a]pyrazine phosphate (1:1) monohydrate, SIT) on metabolism and cardiac function in genetic diabetic Akita mice, 10 weeks old Akita mice were either exposed for 4 months to a high fat and high(More)
Obesity has become a world-wide epidemic and is associated with diseases such as diabetes, dyslipidaemia, cardiovascular disease and certain types of cancers. Understanding the adipose tissue developmental process, involving adipogenesis, angiogenesis and extracellular matrix remodelling, is therefore crucial to reveal the pathobiology of obesity.(More)
The effect of ageing on the morphology of veins, venous valves and arteries was investigated in male wild-type mice using an adapted procedure with injection of a silicone polymer Microfil® that preserves morphology of the vasculature. Throughout the hind limb the arterial, but not the venous, lumen area and wall thickness were significantly greater in(More)
Ageing is associated with an increase in visceral obesity in men and women. Although wild-type mice with a C57Bl/6 genetic background are extensively used in studies on obesity and metabolism, little information is available on age-associated changes in their adipose tissues. We have evaluated development and composition of subcutaneous (SC) and gonadal(More)
To evaluate associations between adiposity and coagulation or inflammation profile, obese wild-type C57Bl/6 mice were subjected to drastic caloric restriction by switching from a high fat diet to restricted normal chow. After 6 weeks, total body weights as well as subcutaneous and gonadal adipose tissue mass were markedly reduced, associated with adipocyte(More)
Genetically diabetic Akita mice, kept on a high-fat and high-cholesterol diet, and treated with the peroxisome proliferator-activated receptor-γ agonist rosiglitazone (10 mg/kg per day during 4 months), displayed rosiglitazone-induced side effects, similar to those observed in patients, including weight and fat gain and early signs of hypertrophic(More)
Epidemiological studies indicate that elderly persons are particularly susceptible to the cardiovascular health complications of air pollution, but pathophysiological mechanisms behind the increased susceptibility remain unclear. Therefore, we investigated how continuous traffic-related air pollution exposure affects haemostasis parameters in young and old(More)
