Abstract
Ataxic rolling Nagoya (PROD-rol/rol) mice, which carry a mutation in the α1 subunit of the Cav2.1 channel (Cacna1a) gene, were discovered in 1969. They show white spots on agouti coat and have a mutation in the piebald spotting (s) locus. However, mutation analysis of the s locus encoding the endothelin receptor type B (Ednrb) gene in PROD-rol/rol mice had not been performed. Here, we examined the genomic and mRNA sequences of the Ednrb gene in PROD-rol/rol and wild-type rolling Nagoya (PROD-s/s) and studied the expression patterns of Ednrb and Cacna1a genes in these mice in comparison with C57BL/6J mice. Polymerase chain reaction analyses revealed two silent nucleotide substitutions in the coding region and insertion of a retroposon-like element in intron 1 of the Ednrb gene. Expression analyses demonstrated similar localizations and levels of Ednrb and Cacna1a expression in the colon between PROD-rol/rol and PROD-s/s mice, but the expression levels of both genes were diminished compared with C57BL/6J mice. Microsatellite genotyping showed that at least particular regions of chromosome 14 proximal to the Ednrb locus of the PROD strain were derived from Japanese fancy piebald mice. These results indicated that PROD-rol/rol mice have two mutant genes, Ednrb and Cacna1a. As no PROD strain had an intact Ednrb gene, using congenic rolling mice would better serve to examine rolling Nagoya-type Cav2.1 channel dysfunctions.
