As women age, the quality of their eggs decline and their chance of having a healthy baby plummets. The accumulation of DNA damage within the egg, and the reduced ability to repair this damage, may be one cause of compromised reproductive success in older women. This project will investigate the ability of eggs to repair DNA damage during maternal aging and will explore the importance of DNA repair to fertility and the transmission of high quality genetic material to their offspring.

The Mutagenic Influence Of 5-methylcytosine And Its Relevance For Cancer Treatment

Summary
Over time our cells accumulate damage to their DNA, which introduces mistakes in the genetic code. These mistakes can alter genes that regulate cell growth and survival and, in this way, they begin the process of turning a normal cell into a cancer. This research is investigating the cellular repair mechanisms that safeguard against DNA damage. Manipulating these repair mechanisms may offer a new way to treat cancer, by selectively inducing DNA damage within cancer cells.
New genomic technologies are revolutionizing biological research. RNA-seq is a recently developed high-throughput sequencing technology that provides scientists with much more detail how genes are regulated and expressed than any earlier technology. New tools developed by Professor Gordon Smyth are allowing researchers to use RNA-Seq technology to more accurately determine which genes are genuinely changing in the development of cancers and in response to cancer treatments.
Understanding Mitochondrial DNA Segregation And Transmission.

Summary
We inherit our mitochondrial DNA from our mothers. Mutations to mitochondrial DNA can give rise to severely debilitating diseases that can be passed from one generation to the next. The aims of this application are to understand how mutant mitochondrial DNA is selected for; when it affects energy production during development; and to ensure that certain reproductive strategies do not result in the adverse transmission of mitochondrial DNA that will affect subsequent generations.
Targeting Bone Marrow Lesions To Find Interventions In The Progression Of Osteoarthritis

Summary
It is essential to elucidate the underlying cause(s) of osteoarthritis because our current level of understanding of this condition has failed to produce effective treatments. Lesions in the bone under the cartilage (BMLs), seen using MRI, have strong potential value for the objective monitoring and management of OA. However, because the nature of BMLs is not well understood, the aim of this application is to perform a comprehensive study of BMLs in OA bone.
Targeting Tau Phosphorylation To Treat And Prevent Acquired Epilepsy, Neurodegeneration And Neuropsychiatric Disease Following A Brain Injury

Summary
This project will explore a new approach to the prevention and treatment of epilepsy and the associated mental health disorders following a brain injury. This involves inhibiting pathological forms of the Tau protein, which has been implicated in the development of epilepsy and neurodegeneration. The drug that will be tested in this study has already been demonstrated to be safe and well tolerated in humans, meaning that a positive result from these studies could be expediently translated into c ....This project will explore a new approach to the prevention and treatment of epilepsy and the associated mental health disorders following a brain injury.

Circulating Tumour DNA To Monitor Treatment Response And Resistance In Chronic Lymphocytic Leukaemia

Funding Amount
$876,950.00
Summary
Many cancers shed small amounts of DNA (ctDNA) into the patient’s bloodstream and recent advances in genomic technologies now allow levels of ctDNA to be accurately measured in the blood. Changes in ctDNA levels have potential to be used as specific markers of disease progression and/or response to cancer therapy. This project will evaluate if ctDNA can be used to monitor treatment responses and individualise treatment decisions in patients with chronic lymphocytic leukaemia.
Leveraging Genomics Strategies To Generate Adult Neurons From IPSCs And Somatic Cells

Funding Amount
$1,593,336.00
Summary
Recent advances have made it possible to derive myriad specialized human cells from stem cells or by directly reprogramming cell identity. However, these derived cells are generally arrested at a fetal developmental stage, and do not mature to function like adult cells. We will use new genomic, epigenetic, cell reprogramming, and manipulation methods to discover how to derive mature cells, aiming to generate mature neurons for use in neurobiology research, disease modeling, and drug screening.
