Gene Affected Cblb: Casitas B-lineage lymphoma b
Origin The transgenic rats were established by injection of transgene consisting of wild-type Cblb into Sprague Dawley (Slc:SD) rat fertile eggs in 2000, followed by backcrossing the transgenic rats onto KDP rats. This transgenic rat expresses the wild-type cDNA of Cblb gene under the control of mouse H2-Kd promoter. (09.7.9)
Strain characteristics KDP is a spontaneous animal model of human type 1 diabetes and a nonsense mutation in Cblb was identified as a causative gene. To confirm that the Cblb mutation is responsible for the phenotype of the KDP rat, wild-type Cblb gene was introduced to KDP rats as rescue experiments. As a result, this transgenic strain was rescued partially (about 30% diabetes incidence as show in KDP) (Yokoi, 2002). (09.7.9)
Breeding Conditions Homozygous Cblb rats are usually infertile in both sexes and are therefore maintained by crossing heterozygous individuals (segregating inbred strain).
