Adaptive reprogramming of metabolism in regeneration. . Biologists have long been intrigued at the phenomenon of organ regeneration. Unlike most human organs, the liver exhibits the remarkable capacity to regenerate. Despite decades of research, the molecular underpinnings of liver regeneration are poorly understood.

Biologists have long been intrigued at the phenomenon of organ regeneration. Unlike most human organs, the liver exhibits the remarkable capacity to regenerate. Despite decades of research, the molecular underpinnings of liver regeneration are poorly understood. This research proposal aims to use zebrafish to elucidate the pathways involved in sensing injury and activating an adaptive transcriptional and metabolic response to orchestrate regeneration. Ultimately, this works aims to understand the metabolic requirements for regeneration. Expected outcomes include scholarly publications revealing fundamental principles of regeneration, new resources and pipelines for the research community as well as training for research students.Read moreRead less

Summary
Identification and characterisation of anti-viral immune response genes in mosquitoes. Emerging viral diseases, transmitted by mosquito bite, present an increasing public health risk globally. Most research to date has neglected the infection dynamic in the insect vector. This project aims to characterise the defensive response of mosquitoes to viral infection, a potentially crucial factor in the epidemiology of vector-borne disease.
Magnetically controlled drug release from tissue scaffolds for the treatment of acute burns. Severe skin burns are frequently associated with functionally disabling scarring and the risk of death. New magnetically activated wound seals for the treatment of acute burns will be developed that reduce the need for frequent painful dressing changes and hence facilitate rapid healing with a significantly reduced chance of scarring.

Cell types and cell states revealed by single-cell regulatory networks. This project aims to use single-cell gene regulation networks to predict cell types. Computational approaches are needed to recapitulate how the over 37 trillion cells program the shared genome sequence in a human body to create astoundingly diverse forms and functions. This project integrates millions of high-resolution single-cell gene expression profiles with large-scale population regulatory data to systematically recons ....Cell types and cell states revealed by single-cell regulatory networks. This project aims to use single-cell gene regulation networks to predict cell types. Computational approaches are needed to recapitulate how the over 37 trillion cells program the shared genome sequence in a human body to create astoundingly diverse forms and functions. This project integrates millions of high-resolution single-cell gene expression profiles with large-scale population regulatory data to systematically reconstruct gene regulatory networks. These networks are the molecular basis for understanding human cells. This projects outcomes intend to include the first reference single-cell regulatory database and novel methods and software to predict individual cells. This project will contribute to advancing Australia's capabilities in single-cell, precision medicine, and big biological data analysis leading to significant scientific, societal and commercial benefits.Read moreRead less
From genotype to phenotype: Molecular photofitting for criminal investigations. DNA found at crime scenes has the potential to provide a physical description of the donor in the same way as an eyewitness statement can be used to make a facial reconstruction. This project will investigate those physical traits which can be derived from the analysis of DNA present in samples collected in relation to criminal activities.

Summary
Exploring new territory in climatic adaptation research: integrating molecular genetics with species' thermal tolerance limits. Predicting species' responses to environmental change requires mechanistic links between whole-organism physiological stress responses and underlying cellular mechanics. This project integrates cutting-edge methods in molecular and evolutionary genetics to probe species' responses to environmental change in the context of a warming environment.
The Stemformatics gene expression compendium: development of multivariate statistical approaches for cross platform analyses. Scientific data is gathered in many different forms, but there are significant gaps in our ability to analyse multiple datasets when generated on different pieces of equipment. This project will study three typical research questions in stem cell biology to develop new analytical approaches to help solve this major data gap.
Uncovering microRNA decay regulation in mammalian cells. MicroRNAs (miRNAs) constitute a novel mechanism used by cells to regulate gene expression, however, very little is known about the mechanisms affecting miRNA accumulation. Characterisation of the kinetics of miRNA turnover is of paramount importance to establish the reliability of miRNAs as novel biomarkers.

MicroRNAs (miRNAs) constitute a novel mechanism used by cells to regulate gene expression, however, very little is known about the mechanisms affecting miRNA accumulation. Characterisation of the kinetics of miRNA turnover is of paramount importance to establish the reliability of miRNAs as novel biomarkers. This project aims to characterise miRNA stability in mammalian cells, investigate mechanisms of turnover and establish their importance on the regulatory function of miRNAs. Such information is critical in the future development of targeted therapeutics.Read moreRead less
Transcriptional regulation by microRNAs. This project aims to better understand microRNAs, which are of central importance to how genes are regulated. Despite recent data indicating microRNAs may also play more extensive and diverse roles as nuclear regulators of gene transcription, research has been restricted to their well known mechanism of action in the cytoplasm where they post transcriptionally silence genes. This project will investigate the potential for microRNAs to regulate transcripti ....Transcriptional regulation by microRNAs. This project aims to better understand microRNAs, which are of central importance to how genes are regulated. Despite recent data indicating microRNAs may also play more extensive and diverse roles as nuclear regulators of gene transcription, research has been restricted to their well known mechanism of action in the cytoplasm where they post transcriptionally silence genes. This project will investigate the potential for microRNAs to regulate transcription on a genome-wide scale and will thereby reveal the full extent of mechanisms by which these important genetic switches control gene expression networks the characteristics of cells. This is of fundamental significance to our understanding of gene regulation.Read moreRead less

Regulation of organ size and stem cell hierarchy in the developing kidney. Transient stem/progenitor cell populations play essential roles in establishing organ systems. The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development.

The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development. Factors produced by undifferentiated progenitors promote organ expansion, whereas differentiation of these cells builds functional capacity. What is not clear is how the balance between self-renewal and differentiation is regulated in these cells, nor how the control of this fate decision impacts on optimal organ development. This project aims to dissect the molecular identity, regulation, and influence of this stem cell population on kidney development.Read moreRead less
