How do apicomplexan parasites steal amino acids from their hosts? The single-celled parasites that cause malaria and toxoplasmosis are adept at stealing nutrients from the host animals that they infect. How they do this is, however, poorly understood. This project seeks to identify the processes by which these parasites scavenge amino acids, an essential class of nutrient, from their hosts. Using innovative experimental approaches, the project aims to identify and characterise the parasite prote ....How do apicomplexan parasites steal amino acids from their hosts? The single-celled parasites that cause malaria and toxoplasmosis are adept at stealing nutrients from the host animals that they infect. How they do this is, however, poorly understood. This project seeks to identify the processes by which these parasites scavenge amino acids, an essential class of nutrient, from their hosts. Using innovative experimental approaches, the project aims to identify and characterise the parasite proteins that mediate the uptake of different amino acids into the parasite. The intended outcomes of the project are to provide comprehensive insights into a fundamental aspect of parasite biology, and inform strategies to treat the diseases caused by these parasites by cutting off their nutrient supply.Read moreRead less

This project aims to investigate how knowledge about the intergenerational transmission of health and disease is shaping antenatal care in Australia. It expects to generate new knowledge about how the science of epigenetics can be used to address social inequality and is anticipated to have impact across the social sciences, bioethics and public health. Expected outcomes of the project include novel theoretical approaches to the ethics of pregnancy, along with guidance tools to shape the use of epigenetics in antenatal care and social policy to reduce social inequalities. This should provide significant benefits, improving information and support available to vulnerable women as they negotiate maternal health and social services. Read moreRead less

RNA-binding proteins rewire transcriptomes in immune cell differentiation. This project aims to combine advanced computational and experimental techniques to investigate a new layer of gene regulation by novel RNA binding proteins (RBP) which control messenger RNA length in immune cells. This project expects to demonstrate that these RBPs have a profound effect on immune cell differentiation and response to infection. Expected outcomes include the discovery of new RBPs regulating immunity, with ....RNA-binding proteins rewire transcriptomes in immune cell differentiation. This project aims to combine advanced computational and experimental techniques to investigate a new layer of gene regulation by novel RNA binding proteins (RBP) which control messenger RNA length in immune cells. This project expects to demonstrate that these RBPs have a profound effect on immune cell differentiation and response to infection. Expected outcomes include the discovery of new RBPs regulating immunity, with mechanism and function determined by novel CRISPR editing of a transgenic mouse model. The significant benefit will be a more complete understanding of RNA mechanisms of immune response, which will be critical in informing future advances in the rapidly developing areas of RNA-based biotechnologies and synthetic immunology.Read moreRead less
Uncovering an evolutionary advanced mechanism of gene expression control. This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes.

This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes. This project will generate new knowledge on the poorly understood process of how the extensive genomic information of multicellular organisms is selectively chosen to enable the expression of only the required subset of genes. This will revolutionise our understanding of the mechanisms of gene control thereby shaping the field in the future. Significantly, this will allow new ways to manipulate gene expression that will impact biotechnology by providing new efficient ways to produce proteins or RNA. Read moreRead less
Force-from-lipids biophysical principle underlying mechanotransduction. The major aim of this project is to determine evolutionary conserved physical principles of mechanotransduction in living cells through structure and function studies of PIEZO mechanoreceptor channels playing a crucial role in senses such as touch and pain in animals and humans. Mutations in these channels can cause numerous genetic disorders, including hereditary anaemias and joint contractures. Since they have been shown t ....Force-from-lipids biophysical principle underlying mechanotransduction. The major aim of this project is to determine evolutionary conserved physical principles of mechanotransduction in living cells through structure and function studies of PIEZO mechanoreceptor channels playing a crucial role in senses such as touch and pain in animals and humans. Mutations in these channels can cause numerous genetic disorders, including hereditary anaemias and joint contractures. Since they have been shown to respond to mechanical stimuli in the same manner as mechanoreceptor channels of organisms from bacteria to humans the intended outcome of this project is to uncover the unifying principles of mechanotransduction anchored in the laws of physics and chemistry that have guided the force-dependent design of all life forms.Read moreRead less
Role of R-loops and double R-loops in genome organisation and transcription. The majority of our genome is converted to an extensive network of non-protein-coding RNA molecules (ncRNAs), but the function of these ncRNAs is unknown. This project aims to identify and determine the mechanism of action of nuclear ncRNA networks with a particular focus on nuclear ncRNAs that form RNA-DNA hybrids with the genomic DNA. These studies have the potential to lead to ground-breaking discoveries in our under ....Role of R-loops and double R-loops in genome organisation and transcription.

This project aims to identify and determine the mechanism of action of nuclear ncRNA networks with a particular focus on nuclear ncRNAs that form RNA-DNA hybrids with the genomic DNA. These studies have the potential to lead to ground-breaking discoveries in our understanding of genome organisation and the mechanism of transcription control, and might provide an entirely new tool-box to manipulate genome function. This should provide significant benefits to efforts to develop innovative biotechnology and genome editing technologies in plants and animals.Read moreRead less
RNA surveillance and the initial steps of RNA biogenesis. This project aims to understand the initial steps of RNA biogenesis and how this process is linked to the chromatin environment. Although less than five per cent of our genome encodes proteins, almost the entire genome is transcribed to RNA. A large portion of these transcripts are degraded during the early steps of RNA biogenesis by the RNA surveillance machinery, but the mechanism for the recognition and degradation of these transcripts ....RNA surveillance and the initial steps of RNA biogenesis. This project aims to understand the initial steps of RNA biogenesis and how this process is linked to the chromatin environment. Although less than five per cent of our genome encodes proteins, almost the entire genome is transcribed to RNA. A large portion of these transcripts are degraded during the early steps of RNA biogenesis by the RNA surveillance machinery, but the mechanism for the recognition and degradation of these transcripts is not understood. New evidence suggests that the chromatin environment of the transcribed locus plays an important role in this process. This project will lead to significant benefits in the implementation of emerging RNA-based technologies and in understanding how genome stability is maintained.Read moreRead less

This project aims to explore how cells physically sense and respond to the surrounding environment on a molecular level. Physical distortion of erythrocytes doubles their glucose consumption and increases cation membrane flux five-fold. This mechanism involves opening of the mechanosenstive ion channel Piezo1.
