Dissecting endocardial signals required for cardiac muscle regeneration in zebrafish. Unlike humans, zebrafish have an extraordinary ability to regenerate their damaged hearts. This project will study the endocardium, a thin layer of cells lining the inner heart, to find important genes for regeneration. Results from this study may provide insights into proper repair of human hearts after injury.
Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that ....Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that have identified the earliest marker of endocardial differentiation and devised the method to make endocardium from stem cells. Knowledge from this work will inform future research into growing and regenerating damaged tissue.Read moreRead less
A multi-model approach to characterise conserved regulators of lymphatic vascular development. Lymphatic vessels are important in a number of diseases affecting Australia. There is a significant gap in our basic knowledge of how lymphatic vessels form. This study will characterise key genes that control lymphatic development, providing a base of knowledge contributing to the promotion and maintenance of good health in Australia.
Heme oxygenase integrates cellular responses to oxygen stress. A deficiency in the protein heme oxygenase-1 causes severe biological consequences including retarded development, chronic inflammation and increased susceptibility to age-associated diseases. By illuminating how heme oxygenase-1 improves cell function the project will eventually assist in preventing or slowing the serious age-associated disorders.
Sprouting Angiogenesis and its Role in Development of Chamber Myocardium. The project aims to investigate how heart chambers form by testing the hypothesis that morphogenesis of the muscular walls of the heart is regulated during development by a Notch signalling-dependent process akin to angiogenic sprouting in other vascular beds. The project outcomes may have implications for diagnosis of congenital heart disease and for the fields of cardiac tissue engineering and regeneration. The project p ....Sprouting Angiogenesis and its Role in Development of Chamber Myocardium. The project aims to investigate how heart chambers form by testing the hypothesis that morphogenesis of the muscular walls of the heart is regulated during development by a Notch signalling-dependent process akin to angiogenic sprouting in other vascular beds. The project outcomes may have implications for diagnosis of congenital heart disease and for the fields of cardiac tissue engineering and regeneration. The project plans to elucidate cellular and molecular pathways underlying heart chamber development in mice using contemporary genetic methods, molecular embryology and imaging. Benefits may include a new framework for understanding heart development and disease, and the future application of this knowledge to translational cardiology.Read moreRead less
Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulatio ....Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulation of non-coding transcripts and genomic instability. This work aims to understand eukaryotic genome organisation and may have long-term therapeutic implications for cancer and ageing-related diseases.Read moreRead less

Stem Cells Australia. Despite progress in stem cell research, scientists do not understand how stem cells “decide” what to become. Stem Cells Australia will draw upon strengths within Australia’s premier stem cell research universities and institutes. This collaboration between leading bioengineering, nanotechnology, stem cell and advanced molecular analysis experts, will fast-track efforts to deliver a fundamental understanding of the mechanisms of stem cell regulation and differentiation, and ....Stem Cells Australia. Despite progress in stem cell research, scientists do not understand how stem cells “decide” what to become. Stem Cells Australia will draw upon strengths within Australia’s premier stem cell research universities and institutes. This collaboration between leading bioengineering, nanotechnology, stem cell and advanced molecular analysis experts, will fast-track efforts to deliver a fundamental understanding of the mechanisms of stem cell regulation and differentiation, and the ability to control and influence this process. Stem Cells Australia will deliver new methods for stem cell propagation and manipulation, new translational technologies for therapeutic applications, and will prepare Australia’s future stem cell scientific leaders.Read moreRead less
