The Role Of Centromere Defects In Cancer Formation And Progression
Funder

Funding Amount
$601,386.00
Summary
When cells divide, their DNA must be copied and distributed faultlessly into the new cells. Defects in the factors that control this process will result in serious health problems including cancer. The objective of this project is to identify what these factors are and study how they contribute to cancer. Results gained from this project are expected to significantly increase our understanding of how cancer cells control the replication of their DNA and therefore their own fate.
A Universal Clinical Test For Gene Fusions In Blood Cancer

Funding Amount
$628,001.00
Summary
Mis-repair of broken chromosomes results in gene fusion and is a common feature of blood cancers. Current tests are only capable of detecting well-known gene fusions and are incapable of identifying new fusion events or fusion variations. We have developed a scientific technique, termed CaptureSeq, that can address these issues. We propose to use this technique as the foundation for a single clinical test for blood cancers, capable of detecting all possible fusion variations – known and unknown.
Diagnosing Chromosomal Translocations In Solid Tumours

Funding Amount
$410,997.00
Summary
Mis-repair of broken chromosomes can fuse together genes that then cause cancer. Current clinical tests are only capable of detecting single well-known gene fusions and are incapable of identifying new fusion events or fusion variations. We have developed a diagnostic technology, termed CaptureSeq, that is capable of finding all fusion genes in a patient sample. In this grant, we will demonstrate the use and advantages of CaptureSeq for diagnosing fusion genes in cancer patients.
Using Mouse Models To Decipher The Function Of Caspase-2 In Limiting Aneuploidy Tolerance And Cancer

$871,162.00
Summary
Aneuploidy or abnormal chromosome number is a feature of cancer cells. The extent of aneuploidy is often predictive of prognosis and the effectiveness of cancer treatment. We discovered that a tumour suppressing protein, caspase-2, is important for deleting aneuploid cells that may otherwise become cancerous. In this project we will use cancer models to decipher how caspase-2 safeguards against aneuploidy and cancer to better understand how cancer cells can survive and be targeted for treatment.
Sex Chromosome Instability In Disorders Of Development

National Health and Medical Research Council
Funding Amount
$627,633.00
Summary
Chromosomes must be copied and distributed faultlessly into the newly dividing cells for normal development to occur. Factors that affect this process are often associated with health problems such as birth disorders, cancer, premature aging and infertility. This project plans to identify genetic factors that compromise the faithful transmission of chromosomes from cell to cell. Results gained from this project will greatly assist in the diagnosis of chromosome-related disorders.
A Single Nucleotide Resolution Map Of A Cancer Associated Neochromosome

Funding Amount
$567,350.00
Summary
Neochromosomes (NCs) are large chromosomes which are not usually found in a normal cell. Well differentiated liposarcoma (WDLPS) is a tumour which is almost universally associated with the presence of NCs. We are using the approach of purifying the NC from a series of WDLPS cell lines, and using new techniques to derive the DNA sequence of the neochromosome. We will use this information to identify the genetic factors on the NC which are involved in the initiation or progression of WDLPS.
Towards Adequate National Provision Of Genomic Testing In Pregnancy

Summary
Genomic information about unborn children can now be provided using chromosomal microarrays which have the potential to revolutionize maternal care in Australia, but are currently only used in high risk pregnancies. Soon all pregnant women, the vast majority who currently have prenatal screening, will be able to access this and other genomic technologies. We will examine the psychological impact of fetal genomic testing and, in doing so, assess the need for service planning, as well as potential ....Genomic information about unborn children can now be provided using chromosomal microarrays which have the potential to revolutionize maternal care in Australia, but are currently only used in high risk pregnancies.

Genomic Signposts, High-resolution Sequencing And Novel Genes In Eye Disease

Funding Amount
$333,694.00
Summary
Blindness is a very distressing sensory loss. Hereditary eye disorders account for the vision impairment in at least one-third of people who are registered as blind. These disorders cause blindness from a young age and work productivity is significantly impaired. This project will identify novel genetic factors in blinding eye disorders. Identifying these genetic factors will lead to better early detection methods for people and improved treatments to prevent the blindness.

Histone H3.3 Dynamics At The Telomere In Pluripotent Embryonic Stem Cells
Funder

Funding Amount
$571,977.00
Summary
The telomere is required for the protection of the chromosome ends. Telomere loses its repeat during each cell division, so telomere shorthening is one of the mechanisms underlying organismal aging as critically short telomeres induce chromosome instability and cell death. Defective telomeres can also result in genetic diseases and development of cancers. Here, we propose to study the mechanism that operates to ensure continual telomere renewal without senescence in embryonic stem cells.
