Summary
The inexhaustible capacity of many pathogens and cancers to develop resistance to new drugs is a serious threat to world health. Yet in acquiring resistance to one drug, many pathogens and cancer cells become hypersensitive to one or more other drugs. We seek to elucidate several of the molecular mechanisms underpinning this phenomenon in the malaria parasite. Insights gained from this work will contribute to the formulation of new therapeutic strategies that overcome or retard drug resistance.
Compound Culture Media To Improve Human IVF Pregnancies

Summary
In Australia 1 in 6 couples require IVF to conceive. Although pregnancy rates have improved over the last 10 years the live birth rate in Australia per cycle is only 17%. This project will assess a new method for the culture of embryos for the ability to maintain embryo vitality and produce healthy babies.
Dissecting The Interactions Of Antimalarial Drugs With The Two Key Determinants Of Drug Resistance In The Malaria Parasite - The 'chloroquine Resistance Transporter' And The 'multidrug Resistance Transporter 1'

Summary
The malaria parasite is a single-celled organism which invades the red blood cells of its host. The aim of this fellowship is to study two proteins that are central to the parasite’s ability to evade the toxic effects of a number of drugs. The parasite's susceptibility to chloroquine, and other drugs, is altered by small changes in these proteins. This work will advance our understanding of the increasingly widespread phenomenon of antimalarial drug resistance, and of how it may be overcome.
Reappraisal Of The Mechanisms Underlying Implantation Success Or Failure

Summary
Infertility affects 1:6 Australian couples; these seek help. However, for each IVF cycle, there is only ~18.5% chance of a live birth, significantly due to failure of embryo implantation. We discovered nano-vesicles in the uterine cavity, that are released from the womb lining and taken up by the pre-implantation embryo to improve its implantation potential. We will determine how this extracellular environment can enhance implantation success and circumvent/management of infertility.
Genetic testing of IVF embryos promises to improve success but shows no effect of live-birth rates. Many embryos are mosaic: containing cells with correct and incorrect chromosome numbers. Current testing is an invasive biopsy which fails to diagnose how many cells are abnormal in the cells that develop into the baby. Here we will use imaging to determine the ratio of abnormal:normal cells resulting in a non-invasive diagnostic that will improve IVF success.
