Description:
The Wilms tumor locus on chromosome 11p13 has been mapped to a region defined by overlapping, tumor-specific deletions. Complementary DNA clones representing transcripts of 2.5 (WIT-1) and 3.5 kb (WIT-2) mapping to this region were isolated from a kidney complementary DNA library. Expression of WIT-1 and WIT-2 was restricted to kidney and spleen. RNase protection revealed divergent transcription of WIT-1 and WIT-2, originating from a DNA region of less than 600 bp. Both transcripts were present at high concentrations in fetal kidney and at much reduced amounts in 5-year-old and adult kidneys. Eleven of 12 Wilms tumors classified as histopathologically heterogeneous exhibited absent or reduced expression of WIT-2, whereas only 4 of 14 histopathologically homogeneous tumors showed reduced expression. These data demonstrate a molecular basis for the pathogenetic heterogeneity in Wilms tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, A -- Campbell, C E -- Bonetta, L -- McAndrews-Hill, M S -- Chilton-MacNeill, S -- Coppes, M J -- Law, D J -- Feinberg, A P -- Yeger, H -- Williams, B R -- New York, N.Y. -- Science. 1990 Nov 16;250(4983):991-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Hospital for Sick Children, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2173145" target="_blank"〉PubMed〈/a〉
