Abstract

The segmental trisomy Ts65Dn mouse is a novel model of Down syndrome (DS). The purpose of this study was to measure brain levels of myo-inositol (ml), N-acetylaspartate (NAA), and other metabolites in Ts65Dn mice using in vivo ¹H magnetic resonance spectroscopy (MRS), and to determine whether lithium (Li) treatment alters brain ml level. The ratio of ml over total creatine (Cr), ml/Cr, was significantly elevated (mean change +38%), while NAA/Cr was significantly decreased (mean change = 18%) in Ts65Dn mice (n = 5) compared with control mice (n = 7). This is consistent with ¹H MRS findings in DS human adults. Brain ml/Cr of the entire sample group (n = 12) was reduced (mean change - 15%) following Li treatment, supporting the Li-induced ml depletion hypothesis. (C) 2000 Lippincott Williams and Wilkins.
