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.

I aim to decipher the role of heritable, genetic DNA variation in human neurological disease. I will use next generation genomics technologies together with sophisticated cellular models to address the important questions of the biology of epilepsy and intellectual disability in particular. I aim to develop a treatment for a specific type of epilepsy, which affects only girls from the age of 6 months. My ultimate goal is to improve the life of the patients and their relatives.

Summary
This project will investigate some of the genetic and epigenetic changes that occur inside certain brain cells that make them selectively vulnerable to Alzheimer's disease, in order to better understand the mechsnisms that give origin to the disease and identify possible targets for precision therapies.
Investigation Of The Functional Role Of Parkin And PArkin Co-Regulated Gene (PACRG) In Neurodegenerative Disease.

Summary
Parkinson’s disease (PD) is a chronic neurodegenerative disorder affecting greater than 1% of the population at 65 years of age. Current treatment regimes treat the motor-associated symptoms of disease - tremor and muscle rigidity. There is no cure, or effective treatment to reverse or halt disease progression. Understanding the role of dysregulated proteins in the progression of PD will identify new targets for treatment of the motor and cognitive deficits observed in PD-affected individuals.

Summary
Schizophrenia is a devastating mental disorder with severe impact not only on the individual, but also on families and communities. Prevalence of the illness is worldwide about 0.5% for all populations. More than 200,000 Australians suffer from schizophrenia, costing the Australian community nearly $2 billion each year. The causes for schizophrenia are still unclear. There is now agreement that nature (genetic factors) and nurture (environmental influences) play a role in the development of the ....Schizophrenia is a devastating mental disorder with severe impact not only on the individual, but also on families and communities. Prevalence of the illness is worldwide about 0.5% for all populations. More than 200,000 Australians suffer from schizophrenia, costing the Australian community nearly $2 billion each year. The causes for schizophrenia are still unclear. There is now agreement that nature (genetic factors) and nurture (environmental influences) play a role in the development of the disorder. Evidence for genetic factors has been obtained and consistently confirmed by family-, twin-, and adoption studies. After many years of research, evidence for several genes, conferring susceptibility to schizophrenia, has been obtained by gene finding approaches applied to large family samples with multiple affected members. However, these genes have to be considered as candidates until more is known about their impact on brain function resulting in schizophrenic disorders. We have dissected a gene locus on chromosome 10p detected by linkage analysis by several groups including ourselves. We obtained statistical evidence for association of DNA sequence variants in the gene encoding the enzyme phosphatidyl-4-phosphate 5-kinase with schizophrenia. This enzyme is a critical component of the phosphoinositide pathways, which are involved in cell signalling. Our aim is to identify a possible dysfunction in the pathways. We will search for mutations involved in function or dysfunction of the enzyme. We will investigate gene- and protein expression and enzyme function in lymphoblast cell cultures and in post mortem brain tissue. Our ultimate goal is to characterise the possible impairment of intracellular cell signalling and thus identify molecular targets for development of novel and specific pharmacological treatments that have the potential to replace the currently available medication which is symptom-oriented and usually accompanied by severe adverse effects.Read moreRead less

Summary
We will investigate variation in the dopamine transporter gene. Variation in this gene will be characterised to a deeper level than has been previously possible using the latest sequencing technology, its biological function will be investigated using biochemical and neuroimaging methods directly in human subjects, and its effects on a clinically important cognitive measure and a common psychiatric condition (attention deficit/hyperactive disorder) will we determined.

Alzheimer's disease (AD) is the most common form of dementia in the ageing population. This research project aims to identify and characterise new genes involved in the copper regulation of the Alzheimer's disease gene. This may lead to the development of novel therapeutic targets and clinical intervention strategies as well as early diagnostic procedures in preventative healthcare for the treatment of AD. The benefits would affect the international community as a whole, potentially minimising the socio-economic costs arising from the predicted world-wide increase in AD in the ageing population.Read moreRead less
