Glucose-6-phosphate dehydrogenase (G6PD) is the key enzyme of the pentose phosphate pathway that catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolactone in presence of NADP + . G6PD is an enzyme of vital importance because of its role in various haemolytic disorders and its potential as a regulator for various biosynthetic pathways. NADPH is the important product of the react...

The variations of glucose 6-phosphate dehydrogenase (G6PD) activity in different brain regions of normal, hypo- and hyperthyroid rats were investigated. Hypo- and hyperthyrodism were experimentaly induced by administration of methimazol and liothyronine, respectively. In normal rats, midbrain had the minimum (70 mU/mg) and cerebral cortex the maximum (349 mU/mg) G6PD activity. Hyperthyrodism in...

Glucose-6-Phosphate dehydrogenase (G6PD) deficiency is a common enzyme deficiency in the world. It's Prevalence inIranis about 12% in male & about 1% in female. The present study did examine the relation between the development of preeclampsia and G6PD deficiency. It was investigated whether or not the risk of preeclampsia in G6PD deficient women is higher than that in normal pregnant women.A t...

Fusions of the first two enzymes in the pentose phosphate pathway, glucose-6-phosphate dehydrogenase (G6PD) and 6-phosphogluconolactonase (6PGL), have been previously described in two distant clades, chordates and species of the malarial parasite Plasmodium. We have analyzed genome and expressed sequence data from a variety of organisms to identify the origins of these gene fusion events. Based...

Plasmodium falciparum growth is impaired in glucose-6-phosphate dehydrogenase (G6PD)-deficient red blood cells (RBCs), and malaria has been implicated in the spreading of deficient variants in malaria-endemic areas. Recent reports suggest that the malaria parasite can adapt itself to grow in these variant RBCs by producing its own G6PD, but studies on parasite G6PD are very limited. In this rep...

background and aims: glucose-6-phosphate dehydrogenase (g6pd) is the first enzyme in the route of pentose phosphate metabolism. this route fulfills an effective role in removing oxidant metabolites. deficiency of this enzyme causes decline in energy regeneration of red blood cells and hemolysis. in this study, application of fluorescence staining method in diagnosing the frequency of g6pd defic...

Immunogenic cell death (ICD) is accompanied by changes in the composition of surface and release soluble mediators. Such signals operate on dendritic cells to stimulate presentation tumor antigens T cells. We recently found that low expression glucose-6-phosphate dehydrogenase (G6PD), a cytoplasmic enzyme involved pentose phosphate pathway, correlates with active anti-tumor immunity. G6PD maint...

Glucose-6-phosphate dehydrogenase (G6PD) in humans is in X-linked disorder, housekeeping enzyme and vital for the survival of every cell. It catalyses the oxidation of glucose-6-phosphate to 6-phospho Gluconat in the first committed step of the pentose phosphate pathway, which provides cells with pentoses and reducing power in the form of NADPH. NADPH is required to protect the cells against ox...

The pentose phosphate pathway (PPP) plays a critical role in macromolecule biosynthesis and maintaining cellular redox homoeostasis in rapidly proliferating cells. Upregulation of the PPP has been shown in several types of cancer. However, how the PPP is regulated to confer a selective growth advantage on cancer cells is not well understood. Here we show that glucose-6-phosphate dehydrogenase (...

twenty five blood samples from 6-month to 5-year old children with visceral leishmaniasis were analysed for various enzymes. aspartate transaminase (ast), alanine transaminase (alt), lactate dehydrogenase (ld) and its various isoenzymes were estimated in the serum, while glucose 6-phosphate dehydrogenase (g6pd) was measured in red blood cells. for comparison, blood samples from healthy children...
