Increased expression of the gene encoding the enzyme glucose-6-phosphatase (G6Pase) contributes to the increased production of glucose by the liver that occurs in individuals with diabetes. Puigserver et al. show that the transcription factor FOXO1 and the transcriptional co-activator PGC-1alpha act synergistically to stimulate the expression of genes in(More)
Gene Expression by Glucagon In Vivo and cAMP In Situ. glucose-6-phosphatase; glucose-6-phosphate) Abstract We recently compared the regulation of glucose-6-phosphatase (G6Pase) catalytic subunit and glucose-6-phosphate (G6P) transporter gene expression by insulin in conscious dogs in vivo (Hornbuckle et al. Am. conscious dogs, a 5 hr period of(More)
The initial stages of diabetic nephropathy are characterized, in part, by expansion of the mesangial matrix and thickening of the glomerular basement membrane which are caused by increased extracellular matrix (ECM) protein synthesis and reduced degradation, a consequence of decreased matrix metalloproteinase (MMP) activity. These changes have been largely(More)
OBJECTIVE Genome-wide association studies have identified a single nucleotide polymorphism (SNP), rs560887, located in a G6PC2 intron that is highly correlated with variations in fasting plasma glucose (FPG). G6PC2 encodes an islet-specific glucose-6-phosphatase catalytic subunit. This study examines the contribution of two G6PC2 promoter SNPs, rs13431652(More)
Elevated fasting blood glucose (FBG) is associated with increased risk for the development of type 2 diabetes and cardiovascular-associated mortality. Genome-wide association studies (GWAS) have linked polymorphisms in G6PC2 with variations in FBG and body fat, although not insulin sensitivity or glucose tolerance. G6PC2 encodes an islet-specific,(More)
Elevated fasting blood glucose (FBG) has been associated with increased risk for development of type 2 diabetes. Single nucleotide polymorphisms (SNPs) in G6PC2 are the most important common determinants of variations in FBG in humans. Studies using G6pc2 knockout mice suggest that G6pc2 regulates the glucose sensitivity of insulin secretion. G6PC2 and the(More)
OBJECTIVE Islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP), now known as G6PC2, is a major target of autoreactive T cells implicated in the pathogenesis of type 1 diabetes in both mice and humans. This study aimed to determine whether suppression of G6p2 gene expression might therefore prevent or delay disease progression. (More)
