Vitamin C Inhibits Aggravated Eryptosis by Hydrogen Peroxide in Glucose-6-Phosphated Dehydrogenase Deficiency

Abstract

Background/Aims: The study was aimed to investigate if vitamin C could exert protective effects on development of eryptosis caused by glucose-6-phosphate dehydrogenase (G6PD) deficiency and hydrogen peroxide. Methods: Isolated erythrocytes with different G6PD activity (normal or deficient) were divided into various groups treated by either Vitamin C or H2O2. Phosphatidylserine (PS) extroversion rate was detected by Annexin V binding. The intracellular Ca2+ concentration was detected by Fluo3-fluorescence, and western blot was used to detect the expression of apoptosis factor caspase 3. Results: Compared with the blank group, the PS extroversion rate (P 2+ concentration (P P 2O2. Then the index of eryptosis significantly decreased after erythrocytes were treated with Vitamin C (1 mg/ml) for 30 min (all P Conclusion: Vitamin C could effectively inhibit the eryptosis contributed by H2O2 oxidative stress, and the suppression on eryptosis with G6PD normal activity was more effective than that with G6PD deficiency.
