Brief description Neuroblastoma is a common cancer of young children which, despite the use of powerful anticancer drugs that cure other childhood cancers, has only a 40% survival rate. Many laboratories have shown that the most aggressive neuroblastoma tumours, which are most resistant to the action of anticancer drugs, have an abnormal number of copies of a cancer-associated gene, called N-myc. Patients whose tumours have multiple N-myc copies have dismal survival prospects, and new treatments for such patients are urgently needed. Several studies, using models of neuroblastoma cells growing in the laboratory, have shown that it is possible to create small fragments of genetic material which can specifically switch off the N-myc gene. When this happens, the neuroblastoma cells behave in a less aggressive and malignant way. We have recently shown that these genetic fragments are capable of reducing the growth of tumours in mice which have been genetically manipulated to develop neuroblastoma. We now want to develop new types of genetic fragments (DNAzymes) that will be even more effective at switching off N-myc and inhibiting neuroblastoma development, because these fragments may be extremely valuable for treating neuroblastoma in patients.
