1. Hypertens Res. 2002 Jul;25(4):605-8. Fine linkage mapping of the blood pressure quantitative trait locus region on rat chromosome 1. Cui ZH(1), Nemoto K, Kawakami K, Gonda T, Nabika T, Masuda J. Author information: (1)Department of Laboratory Medicine, Shimane Medical University, Izumo, Japan. To narrow the area known to contain the blood pressure quantitative trait locus (QTL) on rat chromosome 1, we constructed a fine linkage map covering the blood pressure OTL region on the chromosome using 22 genetic markers informative for stroke-prone spontaneously hypertensive rats of the Izumo colony (SHRSP/Izm) and Wistar-Kyoto rats of the Izumo colony (WKY/Izm). Linkage mapping was done by genotyping 626 backcrossed rats from matings between SHRSP/Izm and WKY/Izm. Nineteen genetic markers informative for the two strains were selected from public databases. Two markers were newly isolated by screening a rat genomic library. One marker was mapped using a restriction endonuclease polymorphism. The region between DlWox29 and D1Smu11 was covered with 22 informative markers placed every 0.6 cM on average. In addition, 6 physiological candidates for a hypertension gene were mapped in this region either by linkage or by radiation hybrid (RH) mapping. This information should be essential for the construction and analysis of congenic strains for this QTL region. PMID: 12358148 [PubMed - indexed for MEDLINE] PUBMED: 12358148
