Summary
Herpes simplex virus (HSV) enters the human body via the skin before entering the termini of nerve cell processes. It is transported along these processes to the body of the nerve cell. HSV lies dormant within these nerve cell bodies near the spinal cord in most people. Intermittently the virus reactivates and is transported back down the nerve cell processes to the skin where it causes blisters-ulcers or is shed without causing symptoms. The aim of this grant is to determine how HSV is transpor ....Herpes simplex virus (HSV) enters the human body via the skin before entering the termini of nerve cell processes. It is transported along these processes to the body of the nerve cell. HSV lies dormant within these nerve cell bodies near the spinal cord in most people. Intermittently the virus reactivates and is transported back down the nerve cell processes to the skin where it causes blisters-ulcers or is shed without causing symptoms. The aim of this grant is to determine how HSV is transported within nerve cells at the molecular level. Recent discoveries have shown how virus transport in nerve cells is dependent on interactions between specific viral proteins and cellular motor proteins and how the virus escapes from nerves to infect skin and cause disease. Such information on viral transport will allow development of inhibitors of this process which may be candidates for use as antivirals for control of recurrent herpes simplex. In addition, this information will allow the virus to be exploited for use in gene therapy to introduce DNA into human nerve cells to correct genetic abnormalities. Finally this data will assist in understanding similar mechanisms for other viruses transported in nerve cells such as those causing shingles and rabies.Read moreRead less

Summary
Herpes simplex viruses 1 and 2 are important pathogens, causing encephalitis, blindness and severe neonatal infection but they also enhance the acquisition of HIV three-fold. The transport of the virus to and from the periphery to the spinal cord is a key component of their life cycle. Determination of the exact mechanism will assist in a general understanding of nerve function and the development of new strategies for antiviral drugs.
Development Of A New High Throughput Screen For Drug Binding To HERG K+ Channels

Summary
Inadvertent drug block of hERG, a potassium channel in the heart, can cause cardiac arrhythmias and sudden cardiac death. Screening for hERG toxicity has become a major hurdle for development of new drugs. We will use a mutant hERG protein that has enhanced drug binding to develop a high throughput test for hERG toxicity. Identification of dangerous drugs early in the drug discovery process will save the pharmaceutical industry millions of dollars in the costs of brining new drugs to market.

Summary
The NHMRC Centre of Research Excellence in Medicines Intelligence is a co-ordinated research program that will accelerate the development and translation of evidence on prescribed medicines use and outcomes for regulators and payers. The CRE is perfectly placed to embrace the national ‘call to action’ from the Health Minister's recent announcement to establish Quality Use of Medicine Safety as a National Health Priority.
Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal coopera ....Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.

Glycine Transporters regulate the concentration of glycine in the spinal cord and brain. It has been suggested that elevating glycine levels in these regions may be useful in treating pain and schizophrenia. This project will provide the basis for the development of new glycine transport inhibitors that may be used to treat these conditions.
Glucocorticoid Resistance In Paediatric Acute Lymphoblastic Leukaemia

Summary
Glucocorticoids are among the most effective drugs used in the treatment of many haematological malignancies, including leukaemia, lymphoma and multiple myeloma. However, the development of tumour cell resistance to these drugs remains a significant problem, and clinically relevant mechanisms of glucocorticoid resistance remain poorly understood. This project aims to define mechanisms of resistance to glucocorticoids and develop new drugs to reverse resistance.

Funding Amount
$631,010.00
Summary
Recent research has focussed on molecular characterisation of high-risk acute leukaemia subtypes. This proposal will combine the power of genomic analysis, global analysis of protein kinases and stringent preclinical drug testing in order to improve the treatment of these high-risk acute leukaemia subtypes. Several innovative and interrelated projects within this Program will utilise a unique and clinically relevant experimental model to achieve their goals.
Sugars in the real world: are cultured cancer cells a good model system for studying protein glycosylation? It is challenging to study errors in metabolism in human beings, so researchers use cells grown in the laboratory to understand disease processes. This project will determine if cultured cells accurately reflect the real changes to cell surface sugars that occur in all cancers, and the effect of these changes on the invasive properties of colon cancer cells.
Targeting Microtubules To Overcome Chemoresistance In Pancreatic Cancer

Summary
Pancreatic cancer is a devastating disease with a dismal prognosis because it is extremely resistant to chemotherapy agents. We plan to examine the expression of proteins called microtubules in pancreatic cancer and assess their role in drug resistance. It is anticipated that the findings of these studies will lead to the development of effective approaches to sensitise the cancer cells to chemotherapy agents.
