| Strain characteristics |
DMY rats exhibit hind limb ataxia and severe myelin breakdown in the CNS during the late stage of postnatal myelination (Kuramoto, 1996; Kuwamura, 2004). By genetic analysis, the causative gene dmy (demyelination) was mapped to rat chromosome 17, very close to the prolactin (Prl) locus (Kuramoto, 1996) and the corresponding mouse genomic region was determined on mouse chromosome 13 (Kitada, 2000). DMY rats show an abnormal ion accumulation and significant upregulation of iron regulatory proteins in the spinal cord white matter (Izawa, 2010). (Oct 8, 2010) |
