Structural alteration of the insulin-like growth factor II-gene in Wilms tumour

J C Irminger et al. Eur J Pediatr. 1989 Jun.

Abstract

In this study messenger ribonucleic acid (mRNA) and DNA of five Wilms tumours were investigated. As expected, the level of insulin-like growth factor (IGF) II-mRNA was elevated up to 50 times in tumour tissue as compared to normal adjacent kidney tissue. In addition, genomic DNA was isolated and digested with appropriate restriction enzymes. Southern blots were prepared and hybridized to IGF II-cDNA probes. Additional bands were present in one of the five Wilms tumours compared to normal tissue. The results indicate a rearrangement of the IGF II-gene on one of the two chromosomes. It is speculated, that this change is responsible for the elevated IGF II expression which may be a factor contributing to tumour growth.
