Glucose-6-phosphate dehydrogenase (G6PD) produces cellular NADPH, which is required for the biosynthesis of fatty acids and cholesterol. Although G6PD is required for lipogenesis, it is poorly understood whether G6PD in adipocytes is involved in energy homeostasis, such as lipid and glucose metabolism. We report here that G6PD plays a role in adipogenesis and that its increase is tightly associ...

Reactive oxygen species (ROS) are constantly generated by cells and ROS-derived damage contributes to ageing. Protection against oxidative damage largely relies on the reductive power of NAPDH, whose levels are mostly determined by the enzyme glucose-6-phosphate dehydrogenase (G6PD). Here, we report a transgenic mouse model with moderate overexpression of human G6PD under its endogenous promote...

The incidence of diabetic nephropathy has been increasing. Studies have shown that oxidative stress (due to increased oxidant production and/or decreased antioxidant activity) is a critical underlying mechanism. The principal intracellular reductant is NADPH whose production is mainly dependent on glucose-6-phosphate dehydrogenase (G6PD) activity. Our work in cultured cells previously showed th...

is known about the safety of RBV treatment in patients with concomitant glucose-6-phosphate dehydrogenase (G6PD) deficiency, who are inherently prone to hemolysis.5 We prospectively studied changes in hemoglobin (Hb) levels in 112 patients with chronic hepatitis C, associated or not with G6PD deficiency, during and after combination therapy. G6PD activity was tested by a spectrophotometric meth...

objectives: controversial findings exist regarding the association between neonate gender and umbilical cord blood lipid levels. this study aims to compare the levels of lipids and lipoprotein b-100 in the umbilical cord blood of male and female newborns and assess the impact of these factors on neonatal anthropometric measurements. methods: this cross-sectional study was performed on 75 health...

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

Background: The aim of this study was to perform a systematic review and meta-analysis on available data about glucose-6-phosphate dehydrogenase enzyme deficiency (G6PDD) status in Iranian neonates screened for the disease. Methods: A literature search was conducted in electronic databases of Embase, PubMed, Web of Sciences, Scopus and Google Scholar for articles published from inception to 1 ...

BACKGROUND Free radical injury contributes to cardiac dysfunction during ischemia-reperfusion. Detoxification of free radicals requires maintenance of reduced glutathione (GSH) by NADPH. The principal mechanism responsible for generating NADPH and maintaining GSH during periods of myocardial ischemia-reperfusion remains unknown. Glucose-6-phosphate dehydrogenase (G6PD), the rate-limiting enzyme...

PURPOSE This study aimed to determine the prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency among infants with neonatal indirect hyperbilirubinemia (NIH); compare G6PD-deficient and G6PD-normal patients regarding hyperbilirubinemia and need for exchange transfusions (ET); and assess risk factors for ET and kernicterus. METHODS This is a case-control retrospective study. Medica...

It has been suggested that the more than 1 million black Americans with the A- variant of glucose-6-phosphate dehydrogenase deficiency (G6PD) are at risk for adverse hematologic effects due to inhalation of ambient levels of oxidant gases. To evaluate this hypothesis studies were performed that included direct exposure of human G6PD-deficient red cells, and of mouse strains with different G6PD ...
