Summary
Infertility comes at an enormous social and financial cost to Australian society; infertility is a major psychological burden on young couples and the technologies used to treat infertility, such as in vitro fertilisation (IVF), require expensive drugs to stimulate the ovary. The cost of these drugs to Medicare is expected to exceed $100 million p.a. over the next decade.

The cost of these drugs to Medicare is expected to exceed $100 million p.a. over the next decade. A reproductive technology, which has always shown great potential to elevate some of this burden, is oocyte (egg) in vitro maturation (IVM), which drastically reduces the use-cost of drugs and the stress to patients. However, oocyte IVM has been slow to live up to its potential and the technology is still not in widespread clinical practice, mainly due to disappointing success rates in women. We have been studying oocyte IVM in animals for many years, and have recently made a significant technological breakthrough, improving success rates by ~50%. In this field, a 50% increase in efficiency is substantial and has significant clinical and commercial application. Currently, we are the only group worldwide with this technology. Over the course of this 2-year project we will conduct follow-up experiments to refine this discovery and investigate the feasibility of using this approach to treat human infertility. We are already in negotiations with two medical device manufacturers to licence this technology. We expect that this project will lead to a series of products and technologies that will enter a clinical trial for the treatment of infertility within 2-3 years.Read moreRead less
Development Of Engineered Novel Growth Factors For Infertility Treatment

Funding Amount
$410,439.00
Summary
Infertility comes at an enormous social and financial cost to Australian society. The aim of this proposal is to improve the success rate of an innovative technology that matures eggs in the laboratory and so eliminates the need for the hormones normally used in IVF. To achieve this a newly discovered egg-secreted protein first has to be produced in the laboratory.
Development Of A Vaccine For Genital Chlamydial Infection

Funding Amount
$207,551.00
Summary
Genital Chlamydia infections are the most common sexually transmitted infection in Australia with annual health costs of 90-160 million dollars. Infection rates in 15-29 olds are increasing at 15-20% per year. Antibiotics are currently the treatment of choice, however antibiotic resistance is increasing and most infections are asymptomatic and not treated in the absence of screening programs. This project aims to develop a genital Chlamydia vaccine using a combination of novel antigens.
Synthesis And Purification Of Flavivirus-specific Antiviral Factor Mrasal

Summary
In this proposal we suggest to develop an anti-flaviviral compound based on naturally occurring host factors associated with inborn flavivirus resistance observed in mice. We propose to synthesise and purify a mouse protein factor encoded by a gene (Mrasal), which we have previously mapped by mouse genetics and positional cloning to a narrow 300 kb chromosomal region on mouse chromosome 5 carrying flavivirus resistance locus (Flv). When this mouse gene was isolated, sub cloned into a mammalian e ....In this proposal we suggest to develop an anti-flaviviral compound based on naturally occurring host factors associated with inborn flavivirus resistance observed in mice. We propose to synthesise and purify a mouse protein factor encoded by a gene (Mrasal), which we have previously mapped by mouse genetics and positional cloning to a narrow 300 kb chromosomal region on mouse chromosome 5 carrying flavivirus resistance locus (Flv). When this mouse gene was isolated, sub cloned into a mammalian expression vector pcDNA3tag and transiently transfected and expressed in cos-7 and Vero cells, its product conferred antiviral effect to a flavivirus Murray Valley encephalitis (MVE), but not to a non-flavivirus encephalomyocarditis virus (EMCV). Mrasal protein operates as an antiviral host factor and confers a flavivirus specific resistance at the cellular level. It could be directly used for the treatment-cure of acute flavivirus infections in vivo. Our aims are to produce and purify the Mrasal protein for the in vivo delivery as a therapeutic compound into susceptible mice during the acute phase of flavivirus infection: 1. To synthesise and purify Mrasal protein using baculovirus system. 2. To encapsulate the protein into liposomes ready to be used in mice. 3. To perform initial testing in a limited number of susceptible mice.Read moreRead less
