glucose-6-phosphate dehydrogenase (g6pd) deficiency is one of the most common hereditary enzymatic disorders in human, increases the vulnerability of erythrocytes to oxidative stress. it is also characterized by remarkable molecular and biochemical heterogeneity. according to previous investigations, g6pd cosenza (g1376c) is a common g6pd mutation in some parts of iran. therefore in the present...

in order to explore the nature of glucose-6-phosphate dehydrogenase (g6pd) deficiency in one of the coastal provinces of the caspian sea (mazandaran) in iran, we have analysed the g6pd gene in 74 unrelated g6pd-deficient males (2-6 year children) with a history of favism, by using pcr and subsequent digestion by appropriate restriction enzymes, looking for the presence of certain known mutation...

A patient with erythroleukemia and heterozygous for the Mediterranean variant of the X-linked enzyme glucose-6-phosphate dehydrogenase (G6PD) was studied to determine the number and type of progenitor cells in which the disease arose. G6PD mosaicism was assessed by the different rate of utilization of 2-deoxy-glucose-6-phosphate (2dG6P) by normal and Mediterranean variants of G6PD. Erythroleuke...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is commonly observed in human males. It is a genetic disorder affecting the red blood cells. The diagnosis of G6PD is usually based on blood analysis and there is no specific molecular or genetic test. The complete gene sequence of G6PD is known for different ethnicities. Known single nucleotide polymorphism (SNP) associated with G6PD is avail...

The most common enzyme defect in humans is glucose-6-phosphate dehydrogenase (G6PD) deficiency, which affects more than 400 million people. G6PD shunts glucose into the pentose phosphate pathway (PPP) to generate nucleotides and reducing potential in the form of NADPH. In this issue, Wang et al (2014) show that G6PD activity is post-translationally regulated by SIRT2, a cytoplasmic NAD-dependen...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked disorder affecting some 400 million people worldwide. Though clinically silent, it may result in hemolysis on oxidative stress induced by drugs or infections. Viral hepatitis A with coexisting G6PD deficiency can be devastating associated with severe hemolysis, anemia, renal failure, and hepatic encephalopathy.

AIMS The effects of ethanol on erythrocyte glucose 6-phosphate dehydrogenase (G6PD) activity were investigated under in vitro and in vivo conditions. METHODS For in vitro studies, glucose 6-phosphate dehydrogenase was purified from human erythrocyte and rats were used for in vivo studies. Enzyme activity was determined spectrophotometrically by the Beutler method. RESULTS The in vitro study...

Highly purified platelet glucose-6-phosphate dehydrogenase (G6PD; D-glucose-6-phosphate:NADP+ 1-oxidoreductase, EC 1.1.1.49) can be modified in its isoelectric point and its molecular specific activity by extracts of some leukemic granulocytes. The "G6PD modifying factors" are relatively small molecules (molecular weight slightly under 5000), thermostable, dialyzable, and ultrafilterable. These...

Any alteration in the optical homogeneity of the lens or decrease in its transparency is known as cataract. Glucose 6 phosphate dehydrogenase (G6PD) activity was measured in both erythrocytes and lenses of study groups and control groups. The decreased activity of G6PD was observed in the study group subjects both in erythrocytes and lenses when compared with controls. These results showed that...
