Gene Affected Anks6 (Pkdr1)
Origin This strain rats was provided to University of Kansas from Central Institute for Laboratory Animal Breeding (Hanover, Germany), and then was introduced to Fujita Health University .
Strain characteristics The causative gene of this rat is named as "Cy" or "Anks6 (Pkdr1)" (commonly expressed as "Cy"). This gene product is "SamCystin" . Cy is inherited in an autosomal dominant manner. The Cy/Cy homozygous and Cy/+ heterozygous rats develop polycystic kidney disease (PKD). The Cy/Cy homozygous rats die of renal failure at around 3 weeks of age. In the Cy/+ heterozygous rats, female rats survive for over 1 year, but the life-span of male rats is within 1 year. In the Cy/+ heterozygous kidneys, cell growth is promoted by activation of signaling pathway such as ERK, and the levels of MCP-1 and osteopontin are increased. In addition, cell growth is promoted by androgen receptor-mediated activation of signaling pathway in the heterozygous male rats.
Breeding Conditions Mating between Cy/+ heterozygous rats.
Genotyping Primers: 5’-CTAGAAGCCTCAGTGACCCC-3’and 5’-CAGCGTGTGAACAAGGTAGG-3’ PCR product (242 bp) is digested with MspI. After digestion, two bands (157 bp and 85 bp) are generated in the wild-type rats and only a single band (242 bp) is detected in the homozygous rats.
