BACKGROUND
Variants on the nucleotide pyrophosphatase/phosphodiesterase-1 (ENPP-1) gene have been associated with obesity and insulin resistance. Because insulin resistance is a pivotal factor in the development of metabolic syndrome (MS) and impaired glucose tolerance (IGT), we aimed to test the
BACKGROUND
The clinical course of chronic hepatitis C virus (HCV) infection is strongly associated with insulin resistance and obesity. The K121Q polymorphism in the ectonucleotide pyrophosphatase/phosphodiesterase (ENPP)-1 gene and the rs7566605 genotype located near insulin-induced gene 2 have
Diabetic nephropathy is the leading cause of end-stage renal disease in the world. The cause of diabetic nephropathy seems to be multifactorial, and about one-third of patients with diabetes eventually develop this complication. The gene encoding ectonucleotide pyrophosphatase/phosphodiesterase 1
Ectonucleotide pyrophosphatase phosphodiesterase (ENPP1) is a positional candidate gene at chromosome 6q23 where we previously detected strong linkage with fasting-specific plasma insulin and obesity in Mexican Americans from the San Antonio Family Diabetes Study (SAFDS). We genotyped 106
OBJECTIVE
Several studies have reported that the ectonucleotide pyrophosphatase phosphodiesterase 1 (ENPP1) K121Q polymorphism (rs1044498) interacts with increased adiposity in affecting glucose homeostasis and insulin sensitivity. Conversely, one would expect that the amelioration of glucose
BACKGROUND
The Ectonucleotide Pyrophosphatase Phosphodiesterasel (ENPP1) polymorphisms have been associated with metabolic traits. There is no data on the effect of ENPP1 in South African children or adults.
OBJECTIVE
To investigate the role of K121Q (rs1044498), rs997509 and rs9402349 in obesity
BACKGROUND
Ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) was recently extensively studied as a candidate gene for obesity phenotypes. As the human homologue of the mouse progressive ankylosis (ANKH) and alkaline phosphatase (ALPL) are known functional partners of ENPP1 in bone
BACKGROUND
ENPP1 (nucleotide pyrophosphatase/phosphodiesterase-1) encodes a membrane-bound glycoprotein that inhibits the insulin-receptor tyrosine kinase activity, resulting in reduced insulin sensitivity. Hence, variants in this gene may be related to obesity and insulin
Type 2 diabetes (T2D) mellitus is a metabolic disorder characterized by chronic hyperglycemia and insulin resistance. It has been a worldwide public health problem, which is increasing rapidly, especially in developing countries such as China. The ectonucleotide pyrophosphatase/phosphodiesterase 1
OBJECTIVE
Findings from the previous studies have suggested a relationship between ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP-1) or plasma cell membrane glycoprotein 1 (PC-1) gene single nucleotide polymorphism (K121Q, rs1044498) and genetic susceptibility to obesity. However, such
BACKGROUND
The metabolic syndrome (MS), a cluster of several metabolic disorders, is increasingly being recognized as a risk factor for cardiovascular disease. Ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), originally described as a plasma cell allo-antigen and named plasma cell
OBJECTIVE
We assessed the predictive value of ectonucleotide pyrophosphatase/phosphodiesterase 1 gene (ENPP1) SNPs with regard to the risk of developing obesity and/or type 2 diabetes in a large French general population.
METHODS
We genotyped the ENPP1 SNPs K121Q (rs1044498), IVS20delT-11
Ectonucleotide Pyrophosphatase Phosphodiesterase 1 (ENPP1) downregulates insulin signaling by inhibiting the insulin receptor's tyrosine-kinase. K121Q and other ENPP1 single-nucleotide polymorphisms (SNPs), IVS20delT-11 and A/G+1044TGA, have been previously associated with obesity in French
Our group has recently demonstrated (Gesta, S., Simon, M., Rey, A., Sibrac, D., Girard, A., Lafontan, M., Valet, P., and Saulnier-Blache, J. S. (2002) J. Lipid Res. 43, 904-910) the presence, in adipocyte conditioned-medium, of a soluble lysophospholipase d-activity (LPLDact) involved in synthesis
The emergence of bone as an endocrine regulator has prompted a re-evaluation of the role of bone mineralization factors in the development of metabolic disease. Ectonucleotide pyrophosphatase/phosphodiesterase-1 (NPP1) controls bone mineralization through the generation of pyrophosphate, and levels
