PURPOSE To investigate effects of vascular endothelial growth factor (VEGF) on glucose transport and GLUT1 glucose transporter expression in primary bovine retinal endothelial cell (BREC) cultures. METHODS Glucose transport in control and VEGF-treated BREC cultures was determined by measurement of [14C]-3-O-methylglucose (3MG) uptake. GLUT1 protein and(More)
BACKGROUND The clinical relevance of the diagnostic criteria for prediabetes to prediction of progression to diabetes has been little studied. We aimed to compare the prevalence of prediabetes when assessed by the new glycated haemoglobin A(1c) (HbA(1c)) 5·7-6·4% criterion or by impaired fasting glucose, and assessed differences in progression rate to(More)
OBJECTIVE To systematically evaluate the association between serum uric acid (SUA) level and subsequent development of type 2 diabetes. RESEARCH DESIGN AND METHODS We searched Medline (31 March from 1966 to 2009) and Embase (31 March from 1980 to 2009) for observational cohort studies examining the association between SUA and the risk of type 2 diabetes(More)
Large Maf transcription factors, which are members of the basic leucine zipper (b-Zip) superfamily, have been reported to be involved in embryonic development and cell differentiation. Previously, we isolated a novel zebrafish large Maf cDNA, somite Maf1 (SMaf1), which possesses transactivational activity within its N-terminus domain. To elucidate SMaf1(More)
In the process of seeking sterol regulatory element-binding protein 1a (SREBP-1a) target genes, we identified and cloned a cDNA clone encoding mouse ⌬ 5-desaturase (D5D). The hepatic expression of D5D as well as ⌬ 6-desaturase (D6D) was highly activated in transgenic mice overexpressing nuclear SREBP-1a,-1c, and-2. Disruption of the SREBP-1 gene(More)
OBJECTIVE Chronic exposure to fatty acids causes beta-cell failure, often referred to as lipotoxicity. We investigated its mechanisms, focusing on contribution of SREBP-1c, a key transcription factor for lipogenesis. RESEARCH DESIGN AND METHODS We studied in vitro and in vivo effects of saturated and polyunsaturated acids on insulin secretion, insulin(More)
The mammalian enzyme involved in the final elongation of de novo fatty acid biosynthesis following the building of fatty acids to 16 carbons by fatty acid synthase has yet to be identified. In the process of searching for genes activated by sterol regulatory element-binding protein 1 (SREBP-1) by using DNA microarray, we identified and characterized a(More)
OBJECTIVE To determine the best lipid variable to predict coronary heart disease (CHD) in Japanese patients with type 2 diabetes. RESEARCH DESIGN AND METHODS Eligible Japanese men and women (1,771) aged 40-70 years with type 2 diabetes from 59 institutes nationwide were followed for a planned 8-year period. The performance of eight conventional lipid(More)
