Segmentally trisomic Ts(1716)65Dn mice provide a postnatal model for Down syndrome. Ts65Dn mice have three copies of most of the genes on mouse Chr 16 that are homologues of human Chr 21 genes. These extra genes, along with the centromere and about 5% of proximal Chr 17 are contained in a small extra chromosome derived from a reciprocal translocation. Neural cognitive deficits and behavioral abnormalities have been noted in Ts65Dn mice. They have spatial learning and memory defects as assessed in the Morris water maze and the radial arm maze, show developmental delay in sensorimotor milestones, and exhibit locomotor hyperactivity, lack of behavioral inhibition, and stereotypic behavior. They perform similar to controls in visual placing, balance, prehensile reflex and traction on a horizontal bar, motor coordination, swimming ability, olfaction orienting. They also show altered noradrenergic transmission in the hippocampus and cerebral cortex and degeneration of basal forebrain cholinergic neurons by 6 months of age. Trisomic females have smaller and fewer litters than euploid females while trisomic males are effectively sterile with hypospermia.Please see Ts(1716)65Dn at the Cytogenetics Models Resource for more information on this strain.

| Molecular Note | About 15% of the distal end of chromosome 16 is fused to less than 10% of the centromeric end of chromosome 17 to form a small translocation chromosome. The translocation breaks mouse Chr 16 just proximal to the amyloid precursor protein ( App ) gene and contains the HSA21-homologous genes from App to the telomere. The translocation chromosome also contains the centromere and a small portion (~5%) of Chr 17. Northern and Western blotting and enzyme activity assays demonstrate that genes on the translocation product are expressed at elevated levels in segmentally trisomic animals.

| Standard Supply | Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement. |
