The Relationship Between Maternal And Infant Dietary Intake Of Fermentable Fibre, Gut Microbiota, Short Chain Fatty Acids And Allergic Disease And Asthma: A Population-derived Birth Cohort Study

Funding Amount
$871,700.00
Summary
The proposed study will involve the Barwon Infant Study (BIS) cohort of 1074 infants to provide the first systematic investigation of the hypotheses that the epidemic of allergic disease and asthma in many parts of the world relates to the paucity of fermentable fibre in the modern diet, and that the protective effect of fermentable fibre is mediated by changes in the organisms that colonise the gut and the metabolites that they produce.

Summary
Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world. Despite this, little is known about how these conditions arise. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of a unique collection of identical twins where one of a pair is sensitive to house dust mite, with cutting edge genomics, to characterise the pathways leading to allergy in ....Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world. Despite this, little is known about how these conditions arise. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of a unique collection of identical twins where one of a pair is sensitive to house dust mite, with cutting edge genomics, to characterise the pathways leading to allergy in children.Read moreRead less
Discovering sex determining genes in a reptile with genetic and environmental sex determination. Reptile sex determination is particularly fascinating because it is triggered either by genes on sex chromosomes or by the nest temperature. This project will identify and characterise candidate sex determining genes in a model reptile to understand how genes control sexual differentiation and how they interact with temperature.
DNA methylation in insect social evolution. This project will investigate the evolutionary relationship between DNA methylation and the advanced sociality displayed by bees, ants and wasps. The project will map DNA methylation across the social insects and test whether it has coevolved with sociality. It will also determine how a vital social cue, the queen pheromone, influences the worker methylome. Finally, it will apply quantitative genetic and methylomic methods to wild insects, revealing pa ....DNA methylation in insect social evolution. This project will investigate the evolutionary relationship between DNA methylation and the advanced sociality displayed by bees, ants and wasps. The project will map DNA methylation across the social insects and test whether it has coevolved with sociality. It will also determine how a vital social cue, the queen pheromone, influences the worker methylome. Finally, it will apply quantitative genetic and methylomic methods to wild insects, revealing patterns of selection and inheritance in epigenetic and phenotypic traits. By combining genomic and evolutionary methods, the project will advance the ongoing debate about the importance of methylation to sociality and extreme phenotypic plasticity. It will contribute to a quantum leap in our understanding of DNA methylation and sociobiology and mark the first application of quantitative genetics to wild insects.Read moreRead less

ARC Research Network in Microarray Technology. The primary aim of this proposal is to transform the premier genomic technology into a standard research tool; microarrays are now a priority for anyone studying the genetics underlying key biological processes. A principal challenge for the Australian research community is to capture all aspects of microarray technology and make them readily available. We will address these needs by developing a network to:

Using genetics to recover Australia's lost history. This project aims to use historic hair samples collected by anthropological expeditions in the early 20th Century to generate the first genetic map of Aboriginal Australia – in order to reconstruct Australia’s pre-European genetic and cultural past. The map and the detailed contextual and genealogical information from museum archives will assist Aboriginal communities and individuals to reconstruct their personal and family history and trace an ....Using genetics to recover Australia's lost history. This project aims to use historic hair samples collected by anthropological expeditions in the early 20th Century to generate the first genetic map of Aboriginal Australia – in order to reconstruct Australia’s pre-European genetic and cultural past. The map and the detailed contextual and genealogical information from museum archives will assist Aboriginal communities and individuals to reconstruct their personal and family history and trace ancestry and augment oral or written records. The combination of cutting-edge science, detailed archival research, and a comprehensive family outreach and reporting program will be a step change in assisting Australia’s reconciliation process, the Stolen Generation, and repatriation of Indigenous remains.Read moreRead less
Uncovering Sex Specific, Epigenetic Biomarkers Of Healthy Ageing For Targeted Exercise Interventions

Funding Amount
$1,449,800.00
Summary
The aged population accounts for a significant, and increasing, amount of Australia’s health budget. We aim to uncover novel molecular biomarkers that slow the ageing process and maintain good health for longer. We will use innovative DNA and protein analysis to study the molecular ‘clocks’ of young and old populations and to test whether exercise can slow the ageing process. This will underpin the development of evidence-based biomarkers to be used in personalised health interventions.
Understanding the evolution of the alternation of generations in the land plant life cycle. This project will investigate the genetic basis and evolution of the land plant life cycle, in which both haploid and diploid phases consist of complex multicellular bodies. The project's findings, which will be made using two model laboratory plants, will be applicable to all plants and will help understand important processes such as pollen and seed production.
ARC Centre for Kangaroo Genome. In this Australian-led Kangaroo Genome Project, we will map and characterize the tammar wallaby genome at the molecular level. Marsupial genomes are uniquely valuable because they provide comparisons that reveal new human genes, regulatory sequences and marsupial-specific genes. These will deliver new products and information useful for medicine, industry, agriculture and conservation. We will construct integrated genetic and physical maps of the genome, clone the ....ARC Centre for Kangaroo Genome.

Marsupial genomes are uniquely valuable because they provide comparisons that reveal new human genes, regulatory sequences and marsupial-specific genes. These will deliver new products and information useful for medicine, industry, agriculture and conservation. We will construct integrated genetic and physical maps of the genome, clone the whole genome as large inserts in BAC vectors, and build a "golden path" with minimal overlap. We will construct libraries of expressed genes from tammar tissues and array them for use in analysing gene expression.Read moreRead less

Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationship with sexual selection. It also proposes ambitious experimental evolution and quantitative genetic studies that will empirically measure the net effect of sexual selection on population fitness and extinction. This project aims to catalyse a change in the study of population fitness and address a conspicuous gap in contemporary evolutionary biology.Read moreRead less
