Summary
Cardiac arrhythmias affect approximately 5% of the population and have a high association with sudden death. Whilst the cause of cardiac arrhythmia is complex, we know that genetic mutations play a role however we don't know all the genes important for cardiac rhythm. It is imperative that we identify all the genes in this process, so we can determine which mutations cause arrhythmia. We have identified a new gene that causes cardiac arrhythmia and seek to understand how it functions.
Systemic lupus erythematosus (SLE) is a condition which causes inflammation in many different organs and can lead to significant suffering and death. Glucocorticoids (GC) are very good at controlling inflammation, however they have severe side effects such as diabetes and bone thinning, and cannot be used long term. This project aims to investigate a protein “GILZ” in patients with SLE. GILZ may have similar anti-inflammatory effects to GC but may not be associated with the same side effects.
Waxing And Waning Of Asthma During Transition From The Teens To Adulthood: Identification Of Immunophenotypic Markers To Predict Disease Trajectory And Guide Development Of Treatment Strategies To Prevent Progression To Chronicity

Summary
The project will seek to identify biomarkers in teenage/young adult asthmatics that can distinguish between those who are "growing out" of the disease, versus those who are progressing towards chronic severe asthma. This knowledge will inform the development of more effective treatment programs for this age group.
Computational Reconstruction And Validation Of A Gene Regulatory Network Controlling Differentiation Of B Cells To Antibody-secreting Plasma Cells

Funding Amount
$618,152.00
Summary
Regulation of B cell differentiation, which occurs when our body responds to antigen infection is tightly controlled by a gene regulatory network. This project will be the first study to reconstruct a regulatory network for this process by using genome-wide expression and transcription factor binding data. The research finding from this study will elucidate the molecular mechanisms regulating this process and will shed new light on how this network is altered in lymphoma and myeloma.
A Zebrafish Model Of Facioscapulohumeral Dystrophy For Therapy Development And Functional Studies

Funding Amount
$390,601.00
Summary
This project seeks to develop a zebrafish model for a genetic muscle-wasting disease called facioscapulohumeral dystrophy (FSHD). Our zebrafish model will enable us to better understand the biological mechanisms underlying the disease, as well as provide a platform for therapeutic testing and discovery.
Revealing How Interactions And Mutation Patterns Among Genes Change In Different Human Tissues By Bioinformatics Tools

Funding Amount
$334,884.00
Summary
Our understanding of common disease is hampered by the complexity of the human system. The DNA variations found in genome wide association studies of common disease are rarely in the gene coding region. I aim to develop statistical bioinformatic tools to find how the DNA variations affect human disease by taking gene expression as the quantitative phenotype. The results will explain the genetic risk of human common disease, so that better personalized prevention and therapy can be achieved.
Correlating Multiple Sclerosis Risk SNPs With Immune Cell Gene Expression

Summary
In Multiple Sclerosis (MS), the immune system repeatedly attacks the brain and spinal cord. In the last three years, rapid progress has been made in understanding genetic risk factors for MS, and more than 20 are known, but their function is not understood. The proposed study will recruit patients with MS and healthy controls to isolate five major immune cell types, and will assess how risk genes influence these cells. We hope to obtain a much better picture of how genetic risk factors for MS ac ....In Multiple Sclerosis (MS), the immune system repeatedly attacks the brain and spinal cord.

The Role Of UPF3B And Nonsense Mediated MRNA Decay Surveillance In The Pathology Of Intellectual Disability.

Summary
Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function. When NMD is compromised the outcome is learning and memory problems, autism or schizophrenia. Under this project we study malfunctioning NMD using stem and neuronal cells derived from patients' skin cells. Some of the affected genes might be considered for therapeutic interventions. NMD is relevant to 1000s of human disorders and as such it is of fundam ....Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function.

Improving Muscular Dystrophy By Targeting The ADAMTS5 Metalloproteinase

Summary
Muscular dystrophy is a devastating childhood disorder. There is no cure and no effective therapy to stop the disease progressing to early death. Our pilot data show that muscular dystrophy in a mouse model is dramatically improved when the Adamts5 gene is inactivated. ADAMTS5 is an enzyme that remodels the extracellular matrix around cells. This suggests that inhibiting ADAMTS5 may be a new way to treat muscular dystrophy. We will test this idea in mice with muscular dystrophy
