Summary
Traumatic experiences are well remembered. In some cases, fear-related memories become debilitating and require therapeutic intervention to diminish the impact of these kinds of memories on daily living. Such therapies engage a process of inhibitory learning called fear extinction. Since anxiety disorders are particularly sensitive to relapse even after extensive exposure therapy, a deeper understanding of the extinction process is crucial if we are to develop more effective treatment protocols ....Traumatic experiences are well remembered.

Transgenerational Impacts Of Paternal Stress On Offspring Mental Health: Epigenetic Mechanisms And Therapeutic Interventions

Funding Amount
$572,941.00
Summary
We are following up the extraordinary, almost ‘Lamarckian’, discovery that environmental influences on fathers can affect their offspring via ‘epigenetic’ changes to the sperm. We will explore mechanisms whereby increased levels of paternal stress can cause behavioural changes in the offspring, which are relevant to depression and anxiety disorders, and how positive environmental factors, including physical activity, may induce beneficial effects. This will have major public health implications.
An Integrated “omic” Approach To Neurodevelopmental Disorders Using Disease-discordant Monozygotic Twins

Funding Amount
$84,800.00
Summary
This project targets neurodevelopment disorders such as autism spectrum disorder, cerebral palsy and epilepsy and focuses on studying the environmental factors (epigenetics) affecting the disease mechanisms in these disorders. The study will be performed on twin samples and will help in the diagnosis of the disease risk at an earlier stage. It will also help to understand the causes of these important neurological diseases.
What Predicts The Progressive Phase Of Multiple Sclerosis

Funding Amount
$1,791,343.00
Summary
We have made major gains in our understanding of what causes MS. What has proven to be far more difficult is understanding the drivers of disability progression and conversion to progressive MS. The onset of progression heralds the accumulation of irreversible disability and is a critical time point to a person with MS. This grant aims to determine the lifestyle, environmental, genetic and epigenetic drivers of MS progression, using an internationally unique Australian MS longitudinal cohort.
L1 Retrotransposition: The Missing Link Between Genetics And Environmental Factors In Parkinson's Disease ?

Funding Amount
$604,644.00
Summary
The study proposed here focuses on understanding the role of specific mobile DNA sequences in the interaction between environmental and genetic risk factors causing Parkinson’s disease (PD) leading to dementia. The project proposes identification of mobile DNA induced mutations in post-mortem human PD patient brain samples. The significance and mechanisms of mobile DNA induced mutations will be then tested in a PD mouse model.
Studying The Interaction Of Reelin Deficiency And Environmental Factors In The Development Of Schizophrenia Using Animal Behavioural Models
Funder

Funding Amount
$438,695.00
Summary
Schizophrenia is caused by an interaction of genetic predisposition and environmental risk factors such as stress or drug abuse. Reelin is a protein involved in the normal development of the brain but its levels are markedly reduced in schizophrenia. We will use mice with low levels of reelin in their brain and assess the effect of environmental stress and drugs of abuse. These studies could elucidate gene-environment interaction in schizophrenia and lead to new treatment strategies.
Integrated Analysis Of Genome, Epigenome, And Transcriptome Data In Schizophrenia

Funding Amount
$417,511.00
Summary
Schizophrenia is a severe psychiatric disorder with a diverse range of symptoms. While the cause is unknown, it is thought to develop from a combination of genetic, epigenetic and environmental risk factors. This study will use genome wide approaches to investigate the relationship between genetic/epigenetic modification of DNA and gene expression in schizophrenia. This study could provide an integrated understanding of the neuropathology of schizophrenia and ultimately lead to better treatment.

Functional role of a novel DNA modification in the adult brain. This project aims to understand how neuronal DNA is modified upon learning and how this impacts memory formation. The project will investigate the combination of different genome-wide sequencing approaches and molecular and cell biological assays to provide new insight into the functional role of a novel DNA modification, N6-methyl-2'-deoxyadenosine in the adult brain. This projects expects to have a major impact on many fields, inc ....Functional role of a novel DNA modification in the adult brain.

Summary
Epitranscriptomic regulation of learning and memory. This project aims to investigate m6A, the most prevalent internal modification in eukaryotic messenger RNA, in the mammalian brain. The adult brain contains a high level of reversible m6A, suggesting that m6A regulates the neuronal transcriptome during synaptic plasticity, the cellular basis of learning and memory. This project will use epitranscriptomics to investigate the more than 100 modifications on RNA, many of which are not yet characte ....Epitranscriptomic regulation of learning and memory.

The adult brain contains a high level of reversible m6A, suggesting that m6A regulates the neuronal transcriptome during synaptic plasticity, the cellular basis of learning and memory. This project will use epitranscriptomics to investigate the more than 100 modifications on RNA, many of which are not yet characterised. Through molecular and mouse behavioural assays, the expected outcomes are insights into the post-transcriptional regulation underlying learning and memory, essential for survival in a constantly changing environment.Read moreRead less
