1 We discovered that valproate regulates expression of 28 genes, including three isoenzymes (M1, A3 and A4) of glutathione S-transferase (GST), an important protective factor against oxidative stress. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
2 We discovered that valproate regulates expression of 28 genes, including three isoenzymes (M1, A3 and A4) of glutathione S-transferase (GST), an important protective factor against oxidative stress. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
3 Because previous studies in our laboratory found that chronic valproate treatment protected cultured neurons against oxidative stress, further experiments on the regulation of GST were performed. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
4 Chronic valproate treatment increased mRNA levels of M1 and A4, but decreased the A3 mRNA level dose-dependently, indicating further complexities in the regulation of GST by valproate. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
5 Chronic valproate treatment increased mRNA levels of M1 and A4, but decreased the A3 mRNA level dose-dependently, indicating further complexities in the regulation of GST by valproate. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
6 The level of GST M1 protein and GST activity were also increased by chronic valproate treatment. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
7 The level of GST M1 protein and GST activity were also increased by chronic valproate treatment. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
8 The present findings suggest that regulation of GST M1, and possibly GST A4, may mediate the anti-oxidative effects of valproate treatment, and regulation of GST may be involved in the mood stabilizing effect of valproate and lithium. Valproic Acid hematopoietic prostaglandin D synthase Rattus norvegicus
