Summary
Neuroblastoma is one of the most common cancers in children. We have found that a genetic regulator, called microRNA, can limit the ability of neuroblastoma cells to invade surrounding tissues and metastasise. We aim use the microRNAs to find new therapeutic targets that may work in combination with existing treatments, reducing the short term toxicity and long term deleterious effects of current treatments.
The Aboriginal Cardiovascular Omega-3 Randomised Controlled Trial

Funding Amount
$1,090,119.00
Summary
CVD is the primary contributor to life expectancy differentials between Indigenous and non-Indigenous Australians. Even when cardioprotective therapies are optimally used, residual risk of adverse events is often observed. Testing of additional therapies that improve survival among Indigenous people with CVD is required. Omega 3 fatty acids can improve multiple atherogenic pathways. This trial will assess the impact of Omega 3 in Aboriginal patients with CVD.
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.

Male-female Sperm Signalling - A Novel Pathway For Peri-conceptual Health?

Funding Amount
$674,920.00
Summary
This project will investigate a new biological process in reproduction, whereby sperm delivered to the cervix at coitus transmit signalling molecules called microRNAs that influence the female immune response, to increase the chances of conception and pregnancy. We will define the molecular details of this signalling pathway in mouse models, and then determine whether human sperm have a comparable function in ‘priming’ the female body to conceive.
A Novel Metabolic Role For UDP Glycosyltransferase 8 (UGT8)

Summary
The UDP glycosyltransferases (UGTs) are a family of enzymes that remove drugs and toxins from the human body as well as control levels of naturally produced molecules such as bile acids and hormones. We found that a new member of this family called UGT8 processes bile acids in the kidney and intestine and can affect how bile acids act to regulate metabolism. Our studies uncover new roles for bile acids in liver, kidney and gut health and in metabolic disorders such as diabetes and obesity.
How IsomiRs Expand The MicroRNA Functional Repertoire In Affecting Gene Expression

Summary
MicroRNAs function as regulators of gene expression. It is becoming appreciated that microRNAs are frequently expressed as variants with subtly different sequences. We find here that variation in one important cancer-associated microRNA, miR-222, promotes differences in the behaviour of cells expressing them. This work seeks to understand how microRNA variation confers such properties to cells, to identify the genes miR-222 variants regulate, and to examine how widespread it is that microRNA var ....MicroRNAs function as regulators of gene expression.

A Randomised Controlled Trial (RCT) Of Azithromycin Versus Doxycycline For The Treatment Of Rectal Chlamydia Infection In Men Who Have Sex With Men.

Funding Amount

Summary
Rectal chlamydia is very common among gay men; it can exist for long periods without symptoms leading to ongoing transmission. Azithromycin (1 gram single dose) or 7 days doxycycline (100mg twice daily) are the two recommended treatments globally. But, there is concern about rectal chlamydia treatment with reports of up to 22% failure following azithromycin. We will conduct a randomised trial to compare these treatments for rectal chlamydia and determine which drug works better.
