title: Polymerase chain reaction-single-strand conformation polymorphism analysis for the VHL gene in chemically induced kidney tumors of rats using intron-derived primers.
abstract: von Hippel-Lindau (VHL) gene mutations occur throughout three exons including the exon-intron boundaries in human VHL disease-associated and sporadic renal cell carcinomas. To explore the possible role of the VHL gene in chemically induced rat kidney tumors originating from various cell types, more than 150 bp of Fischer 344 and Noble rat VHL intron sequences flanking the three exons was determined by dideoxy sequencing. Five primer sets were selected for polymerase chain reaction amplification of the coding regions of rat VHL exons 1-3 and the exon-intron boundaries. Tissues from 10 renal eosinophilic epithelial tumors induced by N-nitrosoethyl(2-hydroxyethyl)amine, 10 nephroblastomas induced by N-nitroso-N-ethylurea, and seven renal mesenchymal tumors induced by N-nitrosomethyl(methoxymethyl)amine were examined for VHL mutations by polymerase chain reaction-single-strand conformation polymorphism analysis. No mutation was detected in any tumor type, indicating that VHL mutations are not involved in the pathogenesis of rat kidney tumors arising from the distal region of the renal tubules, the metanephric blastema, or stromal tissues of the cortex.
