RNA polymerase chain reaction detects different levels of four alternatively spliced WT1 transcripts in Wilms' tumors.
1992
A Wilms' tumor susceptibility gene (WT1) localized to 11p13 was recently isolated and shown to be altered in some sporadic Wilms' tumors. This gene encodes a DNA-binding protein with four zinc fingers (ZFs) in the carboxy-terminal region and a glutamine/proline (Gln/Pro)-rich domain near the 5' end. Two alternative splice sites were described, splice I in the Gln/Pro-rich domain (51 bp) and splice II between ZFs 3 and 4 (9 bp). Using RNA polymerase chain reaction (PCR) we show that Wilms' tumors contain all four possible transcripts, which are also identified in normal adult and embryonic kidney cells
