| Research Abstract |
Chromosomal translocations to generate chimaeric fusion genes are a hallmark of a group of soft tissue sarcomas. Whereas the pathogenic significance of these anomalous genes has been generally established in tumours of this category, the origin of gene fusion still remains unknown. Using DNA microarrays, we observed expression of the genes participating in the DNA double-strand break repair pathways. In two cell lines established from human Ewing's sarcomas, their expression was uniformly elevated. Aberrant expression of double-strand break repair genes may be generally associated with tumourigenesis by the chimaeric fusion genes.
