My research is to learn more of the genetic and epigenetic mechanisms governing the development of the reproductive cell lineage, or the cells that make eggs and sperm. My research is required to better understand human reproduction and human embryonic, fetal and neonatal development, and will help in the treatment of diseases affecting these processes.
Optimising Immunity Towards Cancers By Vaccination.

Funding Amount
$211,320.00
Summary
In this project we will be studying the mechanisms of how an efficient anti cancer vaccine could be generated. We will be using cervical cancer associated human papillomavirus type 16 E7 protein as the model protein in an experimental vaccine model in mice. The results obtained from this project not only able us to design better vaccines against cervical cancers in women but against many other cancers and viruses.
My research straddles biochemistry, cell biology and immunology. I am interested in the mechanisms of antigen presentation by dendritic cells, and the functions of the cystatin family of protease inhibitors.
Defining The Molecular Events That Initiate The Genesis Of Lymphatic Vessels.

Funding Amount
$555,325.00
Summary
Lymphatic vessels are a vital component of the cardiovascular system. Abnormalities in the growth and development of lymphatic vessels are associated with human disorders including lymphoedema, cancer and inflammatory diseases. The focus of this application is to determine the molecular events that initiate the construction of lymphatic vessels, with the aim of identifying targets to which novel therapeutics for the treatment of lymphatic vascular diseases could be generated.
Understanding Natural Killer Cell Development And Target Recognition

Summary
Immune detection and eradication or control of cancer and cancer immunotherapies are based in part on the idea that tumour-specific white blood cells can protect the body from tumour development, growth and metastases. While strong evidence supports this, the means by which these white cells first recognize the cancerous tissue is largely unknown. We will study a new family of white blood cell receptors that may be important in this recognition, either naturally or following therapy.
How Does The Tumour Suppressor: Nerfin-1 Prevent Dietary Dependent Tumour Growth?

Funding Amount
$630,942.00
Summary
The influence of diet has been linked to tumour growth for decades, however, there is little scientific evidence to support or disprove this. In this study, we will assess the effect of diet on tumours in fruit flies. The metabolic genes which regulate the growth of fly tumours will then be studied in human brain tumours. Our studies will ultimately shed light on how tissue growth is controlled by dietary intake, and have the potential to inform the way that we treat and manage human cancers.
A Fluorescent Zebrafish Model Of Endodermal Cell Migration.

Funding Amount
$535,333.00
Summary
The most catastrophic event in cancer progression is when individual cancer cells move to other areas of the body and develop into secondary tumours. This very complex process shows striking similarities to cell movements during embryogenesis. In this project, we use a model system, the zebrafish, to analyse how cells move during embryogenesis. We will determine the genes required for cell movements in the zebrafish embryo, so we can find the corresponding genes in human cancers.
Genomic And Proteomic Dissection Of The Molecular Basis Of Kidney Development.

Summary
The number of nephrons present in the human adult kidney can vary by threefold. This is likely to be due to slight variations in the rate of nephron formation during development. Evidence is mounting that a reduced number of nephrons can predispose to renal failure later in life in response to stresses such as hypertension or substance abuse. 80,000 new cases of end stage renal failure occur each year in the US, with 25% of these related to hypertension and therefore possibly linked to a low nep ....The number of nephrons present in the human adult kidney can vary by threefold. This is likely to be due to slight variations in the rate of nephron formation during development. Evidence is mounting that a reduced number of nephrons can predispose to renal failure later in life in response to stresses such as hypertension or substance abuse. 80,000 new cases of end stage renal failure occur each year in the US, with 25% of these related to hypertension and therefore possibly linked to a low nephron number. While it is known that the kidney arises through a series of reciprocal inductive events between the metanephric mesenchyme and the ureteric bud, a better understanding of the molecular basis of these events is needed to understand what dictates nephron endowment. The Wilms tumour suppressor protein WT1 is not only mutated in some cases of the childhood kidney cancer, Wilms tumour, but is also critical for the normal development of the metanephros, as demonstrated by knockout experiments in mice. One of the earliest genes expressed in the metanephric mesenchyme, WT1 is thought to prevent this tissue from dying before differentiation, directing it to form the kidney and, postnatally, regulating normal podocyte function. Although known to be a nuclear regulatory protein, the genes directly regulated by WT1 have not been clearly or convincingly delineated. This study aims to directly screen for changes to gene expression and protein production levels induced by WT1. To do so, an array approach unique in its use of a specific array set derived from developing kidney will be used. In concert, additional specific clone sets derived from mouse kidney prior and post the commencement of nephron formation will be constructed and analysed. As WT1 is a nuclear protein involved in splicing, this study will involve a parallel investigation at a proteomic level of changes in spliceosomal proteins in response to changes in WT1.Read moreRead less
