Glucose transporters play key roles in the homeostatic control of brain functions. In the present study, we examined the effect of fluoxetine, a selective serotonin reuptake inhibitor, and pergolide, a dopamine D receptor agonist, on the gene expression levels of glucose transporters in the mouse brain. mRNAs for 8 sodium-independent glucose transporters (GLUTs), other than GLUT4 and GLUT9, and sodium-dependent glucose transporter 1 (SGLT1) were confirmed to be expressed in brain tissue. Fluoxetine and pergolide significantly increased the expression levels of mRNAs for GLUT1 and GLUT10 in the brain. Furthermore, the expression of GLUT6 in tissue was increased by administering pergolide to mice. On the other hand, fluoxetine and pergolide had no effect on the expression levels of mRNAs for the other GLUTs and SGLT1. Therefore, we concluded that the gene expression of several GLUT isoforms in the mouse brain was affected by the treatment with fluoxetine and pergolide.
