The role of human single stranded DNA binding protein 1 in the repair of stalled DNA replication forks. It is vital that human cells protect their genetic code in order to prevent cancer. This project will look at how cells do this, with the aim of finding new ways to protect us from cancer.
Imaging Mass Spectrometry (IMS), a peptide biomarker discovery tool using tissue. Cancer is the second most common cause of death in Australia. The newly developed technology of Imaging Mass Spectrometry for peptides in tissue has the potential to discover biomarkers for early diagnosis of cancer. This new technology could avoid a number of cancer deaths and reduce suffering of patients through earlier and better diagnosis.
DNA end resection: from basic mechanisms to genome editing. The project aims to understand processes underlying genome editing, a bioengineering process that introduces specific mutations into genomic DNA. Homologous recombination and nonhomologous end-joining pathways play a crucial role in repairing broken DNA strands, which are a toxic form of DNA damage. The proteins that function in the repair process have been recently identified, but it remains unclear how they function on a mechanistic l ....DNA end resection: from basic mechanisms to genome editing. The project aims to understand processes underlying genome editing, a bioengineering process that introduces specific mutations into genomic DNA. Homologous recombination and nonhomologous end-joining pathways play a crucial role in repairing broken DNA strands, which are a toxic form of DNA damage. The proteins that function in the repair process have been recently identified, but it remains unclear how they function on a mechanistic level and how either of the two main pathways is selected. The project aims to define how the activity of a key control protein, Sae2 (Sporulation in the Absence of Spo Eleven), is regulated by posttranslational modifications, and how this activates homologous recombination. The project plans to first use Saccharomyces cerevisiae yeast as a model and then to extend research into the human system in an attempt to improve the efficiency of genome editing.

Roles of the kynurenine pathway in physiological and pathological brain function. This project will aim to study the metabolism of the essential amino acid tryptophan in the brain and its involvement in diseases including multiple sclerosis and brain tumours.
Structural and functional analysis of the protein kinase R. We have shown that protein kinase R (PKR) plays a key role in regulating the body's response to virus infections, inflammation and cancer. This project will identify mechanisms that regulate the activity of PKR and provide information useful for the development of novel drugs.
Acquisition of the mitochondrial genome restores mitochondrial function. The aim of this project is to show that cancer cells with heavily damaged mitochondrial DNA (mtDNA) can acquire the mitochondrial genome from the host and that this results in the recovery of their mitochondrial function. The project is highly significant, as it aims to show in vivo mitochondrial transfer with functional consequences. The project aims to open a new avenue of research and could result in a shift in our under ....Acquisition of the mitochondrial genome restores mitochondrial function. The aim of this project is to show that cancer cells with heavily damaged mitochondrial DNA (mtDNA) can acquire the mitochondrial genome from the host and that this results in the recovery of their mitochondrial function. The project is highly significant, as it aims to show in vivo mitochondrial transfer with functional consequences. The project aims to open a new avenue of research and could result in a shift in our understanding of some features of cellular communication and how cells can overcome unfavourable situations.Read moreRead less

Single molecule intracellular intravital imaging of actin dynamics. The project intends to develop imaging technology to visualise fundamental processes in cells within a living animal. The focus will be on the actin cytoskeleton, a dynamic macromolecular machine involved in key cellular processes including cell structure, mobility and division. It is exquisitely sensitive to environmental perturbations, requiring it to be studied in cells in living tissue. The project aims to extend the resolut ....Single molecule intracellular intravital imaging of actin dynamics. The project intends to develop imaging technology to visualise fundamental processes in cells within a living animal. The focus will be on the actin cytoskeleton, a dynamic macromolecular machine involved in key cellular processes including cell structure, mobility and division. It is exquisitely sensitive to environmental perturbations, requiring it to be studied in cells in living tissue. The project aims to extend the resolution of live imaging to the single molecule to understand the dynamics of actin assembly with implications for cellular processes that are hijacked in diseases. It also aims to provide a novel assay that may enable testing of the impact of drugs on cellular processes in real time.Read moreRead less

This project aims to establish a three-dimensional (3D) cryo-correlative light and electron microscopy facility. The facility will integrate light microscopy with high resolution cryo-electron tomography and 3D slice-and-view focused ion beam scanning electron microscopy. The open access facility should create new capabilities for Australian researchers to tag biological events and structures with fluorescence markers and image them using the currently highest resolution 3D imaging techniques for biological matter. The facility expects to reveal fundamental insights into cell and structural biology, and help drive innovation in agriculture, pharmaceutics, and biomaterials.Read moreRead less
