Intestinal activities of the redox enzymes, GSH peroxidase, GSSG reductase, and glucose-6-phosphate dehydrogenase (G6PD), were significantly decreased by 17 hours' insulin treatment, whereas only G6PD was decreased by fasting.

|
Insulin treatment for 7 consecutive days increased hepatic G6PD activity by fourfold but was without effect on intestinal G6PD, suggesting tissue specificity in insulin regulation of G6PD.

Adipogenic G6PD overexpression promotes the expression of pro-oxidative enzymes, including inducible nitric oxide synthase and NADPH oxidase, and the activation of nuclear factor-kappaB (NF-kappaB) signaling, which eventually leads to the dysregulation of adipocytokines and inflammatory signals.

|
The isoforms of the transcription factor sterol regulatory element binding protein 1 (SREBP-1) are known to stimulate G6PD gene expression, and some polymorphisms in the SREBP-1 gene (SREBF-1) have been described only in Africans.

|
Inhibition of PI3 kinase and Src kinases decreased (p < 0.05) G6PD activity in the fa/fa but not in the lean rat liver, suggesting that G6PD activity is regulated by PI3/Src kinase signaling pathways.

|
G6PD-derived NADPH increased (p < 0.05) superoxide anion levels by 70-90% in fa/fa vs lean rat liver, which was inhibited by the NADPH oxidase inhibitor gp91(ds-tat) (50 microM) and G6PD inhibitors 6-aminonicotinamide (1 mM) and dehydroepiandrosterone (100 microM), therefore indicating that elevated G6PD activity may be responsible for mediating superoxide generation.

|
G6PD-deficient mice had increased protein kinase C activity, increased nuclear factor-kappaB activity, and increased urinary albumin levels, all of which is similar to changes seen in diabetic mice.

Conversely, G6PD deficiency can promote oxidative stress and impairment of insulin secretion by beta cells.

|
In INS-1 cells, G6PD overexpression augmented ROS accumulation associated with increased expression of prooxidative enzymes, such as inducible nitric oxide synthase and reduced nicotinamide adenine dinucleotide phosphate oxidase.

Inhibition of G6PD with siRNA led to increased ROS and apoptosis, decreased proliferation, and impaired insulin secretion.
