Summary
Human high grade gliomas (HGG) present as heterogeneous disease, primarily defined by the histologic appearance of the tumor cells.Glioblastoma multiforme (GBM) is the most common illness and continues to have a very poor prognosis, despite the use of multimodality therapy including surgery, radiation therapy and chemotherapy. We will use our existing biobank of specimens, clinical information and molecular investigation to identify factors that determine outcomes.
This study will address the idea that cancer commonly involves a genetic pathway that is normally used by stem cells to proliferate in an undifferentiated state. We have evidence to indicate that this system is active in cancer cells and believe this could explain how cancer cells manage to divide rapidly in a primitive state. This project may bring a new perspective to the study of malignant transformation and has the potential to reveal multiple new targets for cancer therapy.
Somatic Retrotransposition Drives Neoplastic Mutagenesis In Glioblastoma Multiforme

Summary
Retrotransposons are mobile genes that copy-and-paste themselves in our genome. Previously thought to represent “junk DNA”, retrotransposons are increasingly found to play major roles in biology. In a recent landmark publication in Nature, we demonstrated that retrotransposons move in the healthy human brain. In the current study, we will use cutting-edge technologies to determine whether brain cancer can occur as a result. This will provide new perspectives of the genetic basis for cancer.
Genetic And Genomic Dissection Of Polycomb Repressive Complex 2 (PRC2) In Cancer

Summary
The evolution of normal cells to cancer involves mutations that activate cancer-causing genes and/or prevent the actions of anti-cancer genes. It has become increasingly evident that cancer development also involves changes to epigenetic regulation, or control of gene activity by chemical modification of the gene or its environment rather that changes in DNA sequence. This project aims to explore the tumour suppressor activity of an important epigenetic regulatory complex in lymphoma.
HIC1 Prevents Tumour Initiation By Maintaining Genomic Stability

Summary
Chromosomes are large structures that package the genome. Abnormalities in the structure and function of chromosomes are now recognised an in important driver of cancer. Using a genetically engineered mouse model this project seeks to understand how this process evolves from the very earliest stages in the evolution of a tumour.
Genomic Analysis Of The Novel Epigenetic Modifier Smchd1 As A Tumour Suppressor

Funding Amount

Summary
Epigenetic modifications are changes made to our DNA that act like punctuation marks in the genome, to instruct the cell when to turn genes on and when to switch them off. Epigenetic control is critical to range of different biological processes, and also goes awry in cancer. We are specifically interested in the role of one new protein involved in epigentic control and characterising its role as a tumour suppressor.
