Understanding The Mechanisms Of PTEN Transfer Into Glial Cells Using Exosomes

Funding Amount
$567,253.00
Summary
This application will develop a new way of treating brain cancer which currently affects 1500 adults in Australia per year with no lasting cures. The average patient with a malignant brain tumour do not survive for more than 12 months. We have discovered a method of restoring a cancer suppressor substance that is lost from brain tumours. If successful, this treatment has the potential to limit or reverse the progression of brain tumours.
Aberrant Ependymal Development And The Formation Of Hydrocephalus
Funder
National Health and Medical Research Council
Funding Amount
$660,005.00
Summary
Foetal hydrocephalus is a prevalent neurodevelopmental condition associated with severe intellectual impairment. Breakdown of the ependymal cell layer, which acts as a barrier between brain tissue and the ventricular space, is a major cause of hydrocephalus. Despite the importance of these cells, we have little understanding of the molecular mechanisms that regulate their production. This project will identify critical signalling pathways governing the establishment of the ependymal layer.
Pathogenesis And Therapeutic Modulation Of Aggressive Behaviour In A Mouse Model Of Autism Spectrum Disorder
Funder
National Health and Medical Research Council
Funding Amount
$583,015.00
Summary
This project focuses on understanding the causes of aggressive behaviour in mice that have a human gene mutation found in autism. Aggressive behaviour is common in autism patients and can have severe consequences on education and employment opportunities. These mice also show excess dampening of brain function (inhibition). This project will test if aggression in these mice is caused by altered inhibition.
Neogenin: A Molecular Determinant Of Neural Progenitor Polarity And Function
Funder
National Health and Medical Research Council
Funding Amount
$569,296.00
Summary
The neuroepithelium (NEP) contains the embryonic neural stem cells essential for the production of all neurons in the adult brain. Failure in NEP function leads to devastating neural tube defects and syndromes such as epilepsy, schizophrenia, and mental retardation. This project will identify the molecular mechanisms regulating NEP stem cell activity and the birth of new neurons in the embryonic neocortex.
Understanding The Embryonic Origins Of Cortical Malformations
Funder
National Health and Medical Research Council
Funding Amount
$815,228.00
Summary
Cortical malformation leads to mental retardation and epilepsy. Identification of the aberrant developmental processes contributing to these devastating syndromes is essential for accurate clinical assessment and development of novel therapeutics. Here we investigate a developmentally important receptor, Neogenin, which when mutated, leads to cortical malformations. Determining how Neogenin functions is expected to uncover new signaling pathways contributing to these malformations.
