Title: Increased folate uptake prevents dietary development of folate deficiency in the rat brain

Abstract

Folic acid and folate deficiency have been implicated in disorders of the central nervous system. In a study of the mechanism for the effects of chronic ethanol on folate homeostasis, the uptake of {sup 3}H-folic acid by the rat brain has been studied. Male Sprague-Dawley rats were fed sulfonamide-supplemented folate-sufficient and folate-deficient liquid diets containing either ethanol or isoenergic carbohydrate as a control. After 16 weeks, severe folate depletion occurred in tissues (liver, kidney, spleen, lung intestine, testes), but not in the brain. Tissue retention of {sup 3}H-folic acid was increased four-fold in the brain of folate-deficient rats. A smaller increase in uptake was observed in the other tissues, except for the liver, in which the retention of {sup 3}H-folic acid was slightly decreased. Chronic ethanol feeding decreased hepatic folate uptake, but not that by the increase the uptake of folate from the plasma of folate-deficient rats, thereby inhibiting the development of brain folate deficiency.
