Randomized trial shows increased G6PD expression in PC12 cells under chronic hypoxia, indicating redox status involvement.

This research investigates how chronic hypoxia regulates glucose-6-phosphate dehydrogenase (G6PD) gene expression in PC12 cells.
Examined G6PD mRNA levels and activity in PC12 cells under chronic hypoxia.
Utilized cobalt chloride and dimethyloxalylglycine to mimic hypoxia.
Assessed the effect of antioxidants on G6PD induction.
G6PD mRNA and activity increased in a dose- and time-dependent manner under hypoxia.
Induction of G6PD was negligible in non-excitable Buffalo rat liver cells while PGK1 was strongly upregulated under low oxygen conditions.
Blocking agents (glutathione and N-acetylcysteine) inhibited hypoxia-induced G6PD expression.

Gao et al. (2004) studied this question.
