A Wnt coreceptor low-density lipoprotein receptor-related protein 5 (LRP5) plays an essential role in bone accrual and eye development. Here, we show that LRP5 is also required for normal cholesterol and glucose metabolism. The production of mice lacking LRP5 revealed that LRP5 deficiency led to increased plasma cholesterol levels in mice fed a high-fat(More)
Recent epidemiological studies have associated type 2 diabetes mellitus with an increased risk of developing Alzheimer's disease (AD). A dramatic decrease in glucose utilisation has been observed in the brains of AD patients, and this decrease has led to the hypothesis that the cognitive dysfunction in AD is associated with decreased central glucose(More)
The serum lipoprotein(a) [Lp(a)] concentration is under genetic control, and most humans have values lower than 30 mg/dL. Subjects with markedly elevated serum Lp(a) concentrations, that is, > or =100 mg/dL, are rarely encountered, and these subjects have not yet been fully characterized from the clinical point of view. In the present investigation, we(More)
AbstractGlycogen storage disease type III (GSD III) is an autosomal recessive disorder characterized by excessive accumulation of abnormal glycogen in the liver and/or muscles and caused by deficiency in the glycogen debranching enzyme (AGL). Previous studies have revealed that the spectrum of AGL mutations in GSD III patients depends on ethnic grouping. We(More)
OBJECTIVE Some type 1 diabetic patients have a distinct phenotype characterized by the absence of pancreatic autoantibodies and fulminant clinical symptoms at onset, including marked hyperglycemia, severe diabetic ketoacidosis, and normal to near-normal HbA(1c) levels with complete destruction of beta-cells. However, little is known about genetic factors of(More)
Glycogen storage disease type IIIa (GSD IIIa) is an autosomal recessive disorder caused by deficiency of the glycogen-debranching enzyme (AGL). Recent studies of the AGL gene have revealed the prevalent mutations in North African Jewish and Caucasian populations, but whether these common mutations are present in other ethnic groups remains unclear. We have(More)
Histopathological changes of biopsied pancreata were examined in three diabetic patients with autoimmune chronic pancreatitis (ACP). We found intra- and periinsular mononuclear cell (MNC)-mainly CD8+ T cell-infiltration as well as MNC infiltration around the ductal cells. Islet beta cell volume decreased significantly. Some ductal cells expressed insulin(More)
Type 2 diabetes mellitus is associated with a marked increase of coronary heart disease (CHD). We aimed to assess the impact of elevated serum lipoprotein (a) (Lp[a]) concentrations on the risk of CHD in patients with type 2 diabetes mellitus. A consecutive series of 352 outpatients was investigated. We determined the serum lipid profile and checked the(More)
We previously demonstrated that intracerebroventricular streptozotocin (STZ-icv) injection induced cognitive dysfunction and led to decreased expression levels of phospho-cyclic AMP responsive element binding protein (pCREB), Akt, and insulin degrading enzyme (IDE) and increased amyloid beta (Ab) deposition in the hippocampus. In the present study, we aimed(More)
OBJECTIVE To investigate the association between eating behaviour and metabolic risk in the broader population. DESIGN The association between metabolic risk factors (overweight, hypertension, hyperglycaemia, hypertriacylglycerolaemia, low HDL cholesterol, hyperuricaemia and fatty liver) and various eating behaviours were compared for four groups defined(More)
