Abstract

In this study, we investigated the effect of fish oil on gene expression in the cerebral cortex, and found that 5-aminolevulinate synthase 2 (ALAS2) mRNA expression was up-regulated by fish oil feeding. ALAS2 promoter activity was found to be regulated by retinoic acid. Our results suggest that fish oil modulates neuronal functions via heme synthesis.
