Origin |
Zitter rat was detected in a Sprague Dawley colony (SD) in Hannover in 1978 by Rehm. 1983 introduced to Kyoto University and established ZI. (Jan 26, 2010) |
Strain characteristics |
ZI strain develops a generalized body tremor at about 15 days of age, and with increasing age a progressive flaccid paresis of the hind limb occurs (Rehm, 1982). The main pathological findings are hypomyelination and vacuolation in the central nervous system (Rehm, 1982, Kondo, 1991). By positional cloning, a marked decrease in Atrn mRNA in the brain of the ZI rat and zi as an 8-bp deletion at a splice donor site of intron 12 of Atrn were found (Kuramoto, 2001). (Jun 19, 2009) |
