Can we exploit mRNA modifications to control protein expression? Genes are encoded by DNA but are transcribed into a message called RNA before they can be translated into protein. RNA can be chemically modified at a gene-specific level, and this modification has been central to the success of RNA vaccines against COVID-19. Despite the importance of these modifications in cellular life and in biotechnology, the role of the most abundant RNA modifications is unclear. This project will investigate ....Can we exploit mRNA modifications to control protein expression? Genes are encoded by DNA but are transcribed into a message called RNA before they can be translated into protein. RNA can be chemically modified at a gene-specific level, and this modification has been central to the success of RNA vaccines against COVID-19. Despite the importance of these modifications in cellular life and in biotechnology, the role of the most abundant RNA modifications is unclear. This project will investigate how we can exploit RNA modifications to modulate protein expression in a tractable single-celled organism with a small genome, Plasmodium. This information is important because understanding gene regulation is fundamental to all life, and the role of RNA modifications is emerging as integral to biotechnology.Read moreRead less
Understanding how the heart becomes more efficient. The body demands that the heart function at utmost efficiency. Trabeculae – folds within the heart lumen – maximise blood flow, contribute to chamber development and form the electrical conduction network of the heart. Problems with trabeculae formation cause cardiomyopathy and arrhythmia and yet we do not understand its basic development. The project will investigate the earliest stages of when this tissue develops its identity and examine the ....Understanding how the heart becomes more efficient. The body demands that the heart function at utmost efficiency. Trabeculae – folds within the heart lumen – maximise blood flow, contribute to chamber development and form the electrical conduction network of the heart. Problems with trabeculae formation cause cardiomyopathy and arrhythmia and yet we do not understand its basic development. The project will investigate the earliest stages of when this tissue develops its identity and examine the signalling, genetic, cellular and extracellular cues required to instruct trabeculae to form in the heart. Findings from this research will revise our understanding of when and how trabeculae form and provide key information about how to grow and repair this important tissue.Read moreRead less
Can parasites cause host population divergence? . Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa. This species provides an unpreced ....Can parasites cause host population divergence? . Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa. This species provides an unprecedented system, backed by 37 years of long term host-parasite and behavioural data, and recent genetic analyses. This project intends to produce significant data to allow an examination of the early stages of host-parasite evolution in action, providing novel insights into the speciation process.
