The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Integrated Analysis And Functional Characterisation Of Gene Amplicons In Ovarian Cancer

Funding Amount

Summary
In Australia in 2001 there were ~1300 new cases of ovarian cancer. Survival of ovarian cancer is very poor and current treatments inadequate. To develop more effective treatments we need to understand the molecular events that cause ovarian cancer. Some genes have multiple copies in ovarian cancer cells and these may be good targets for therapy. We aim to find these genes and determine which ones have a functional effect in the tumour.
Downregulation Of N-myc Oncogene Expression As A Therapeutic Strategy For Childhood Neuroblastoma.

Summary
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 ....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.Read moreRead less
