The hexose-monophosphate shunt is also known as the phosphogluconate pathway and the pentose phosphate pathway. It is the secondary pathway in glucose metabolism (primary is glycolysis). In the context of immunomodulation, a target (primarily the enzyme G6PDH) for effects on production of reducing ...
G6PD activity is essential to normal functioning of the hexose monophosphate (HMP) shunt. This pathway generates reduced nicotinamide adenine dinucleotide phosphate (NADPH), a cofactor in glutathione metabolism in human RBCs. The HMP shunt is tightly coupled to glutathione metabolism, which serves to ...

Glucose-6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate, dehydrogenase the key enzymes of the hexose monophosphate shunt pathway, were measured in both surrounding and tumoral lung tissues from normal and G6PD-deficient subjects. A significant increase of these enzymatic activities in tumoral tiss...
G6PD is allosterically regulated by the cellular [NADPH]/ [NADP+] ratio. When the ratio is high (lots of NADPH) G6PD is OFF. When the ratio is low (low NADPH), G6PD is ON. Insulin induces G6PD expression, resulting in higher enzyme levels & increased activity of the HMP. ...
G6PD enzyme is the first and control step of the pentose phosphate pathway (PPP) also known as the phosphogluconate pathway, hexose monophosphate pathway (Coleman and Allen, 1978), hexose monophosphate shunt (Akram et al., 2019), which is found in all organisms, from prokaryotes to eukaryotic ...
