Circulating Tumour DNA To Monitor Treatment Response And Resistance In Chronic Lymphocytic Leukaemia

Funding Amount
$876,950.00
Summary
Many cancers shed small amounts of DNA (ctDNA) into the patient’s bloodstream and recent advances in genomic technologies now allow levels of ctDNA to be accurately measured in the blood. Changes in ctDNA levels have potential to be used as specific markers of disease progression and/or response to cancer therapy. This project will evaluate if ctDNA can be used to monitor treatment responses and individualise treatment decisions in patients with chronic lymphocytic leukaemia.
Investigating The Link Between Oxidative Stress And Biomechanical Integrin Activation In Diabetes

Summary
Diabetes represents a serious healthcare problem globally. A large proportion of deaths associated with diabetes can be attributed to the development of blood clots in the circulation of the heart and brain (heart attack/stroke). The blood clotting mechanism is ‘hyperactive’ in diabetes, although the reason for this is not well defined. In this proposal we will investigate a new mechanism promoting blood clots, and will investigate innovative approaches to reduce this clotting mechanism.
The Genetic And Environmental Determinants Of Amyloid Deposition In Older Individuals: An Amyloid Imaging Study Using The Twin Design

Summary
Alzheimer’s disease is characterised by the deposition of amyloid plaques in the brain. We don’t fully understand how amyloid deposition occurs and what contribution is made by genetic and environmental factors. Amyloid deposition in the brain can now be quantified during life using positron emission tomography. In this study, we will examine brain amyloid in twins, which will determine what proportion of the pathology is attributable to environmental factors that may be modifiable.

Summary
Treatment of ductal carcinoma in-situ (DCIS), a preinvasive form of breast cancer, is aimed at preventing invasive cancer recurrence. Women with higher-risk DCIS have an increased risk of recurrence. This study aims to individualise treatment for women with DCIS to achieve long-term tumour control with minimal treatment toxicity. After local excision of DCIS, radiotherapy (RT) to the whole breast reduces the recurrence rate.

Women with higher-risk DCIS have an increased risk of recurrence. This study aims to individualise treatment for women with DCIS to achieve long-term tumour control with minimal treatment toxicity. After local excision of DCIS, radiotherapy (RT) to the whole breast reduces the recurrence rate. However, it is unclear if escalating radiation dose to the tumour bed in higher-risk women increases tumour control. It is also uncertain if giving fewer but larger radiation doses over 3-4 weeks would achieve the same tumour control as the standard 5-7 week course of RT to improve patient convenience and access to RT. Thus, this multicentre study of 610 women with higher-risk DCIS will investigate if adding a tumour bed radiation boost after whole breast RT improves tumour control, and the shorter RT course achieves the same tumour control as the standard longer course. Currently, the ability to predict the malignant potential of DCIS and RT toxicity is limited. This study will investigate if there are biological and genetic markers predictive of invasive recurrence and normal tissue toxicity in women with DCIS using state of the art technology. Women need to weigh up the likelihood of cancer control against adverse treatment effects to make an informed treatment decision. However, very little is known about the quality of life (QoL) consequences of the diagnosis and treatment of DCIS. In this study, the QoL, psychological distress, perceived risk of invasive cancer recurrence and perceived cosmetic outcomes of women with DCIS, will be assessed using a questionnaire of validated measures. This study will refine treatment for women with DCIS according to their risks of recurrence. It will significantly advance the understanding of the biology of DCIS and its psychological and QoL outcomes after treatment.Read moreRead less

How Do Thick Airway Walls Affect Airway Hyperresponsiveness In Asthma?

Funding Amount
$382,538.00
Summary
Asthmatic airways narrow too easily, a characteristic called airway hyperresponsiveness (AHR). To understand the cause of asthma we need to understand the cause of AHR. Thickened airway walls could amplify airway narrowing and increase AHR. However, thick airway walls are also stiff, and stiff walls could reduce narrowing and AHR. This project will examine the relationships between AHR and airway wall thickness and stiffness during and after treatment that reduces airway wall thickness.
The Role Of Melanoma Tumour Antigen P97 (Melanotransferrin) In Melanoma Tumourigenesis.

Summary
The Role of Melanoma Tumour Antigen p97 (Melanotransferrin) in Melanoma Tumourigenesis Melanotransferrin (MTf) is a homologue of the iron transport protein, transferrin, and was one of the first well characterised melanoma tumour antigens. Our published studies have shown that MTf plays an important role in melanoma tumourigenesis in vivo. In this proposal, we will assess if it is associated with melanoma progression in patient samples and examine its role in melanoma growth and metastasis.
The Immunoregulatory Role of the Endogenous Cannabinoid Anandamide. Anandamides are naturally occurring fatty acids that act at the cannabinoid receptor expressed in the brain and periphery.

Anandamides are naturally occurring fatty acids that act at the cannabinoid receptor expressed in the brain and periphery. A new proposal by our research group challenges traditional models of the disease process by suggesting that the anandamide system is an important imunoregulatory system that can be targeted by invading pathogens. We propose that disruption to the anandamide system, by bacteria or viruses acting at the receptor to block immunological responses, contributes to chronic illness states. At this point we have good evidence that anandamides are immunoregulators, however, we have very little knowledge of their precise physiological role. The aim of this research is to begin to characterise the immunoregulatory role of the anandamide system. This project will provide a comprehensive understanding of this endogenous control system, the immunological properties of which have not previously been described. The outcome of this research may lead to the identification of new avenues for the development of pharmaceutical interventions that can target this system.Read moreRead less
Alcoholic Chronic Pancreatitis: Induction, Progression And Reversal

Summary
Pancreatitis (inflammation of the pancreas) is a serious complication of alcohol abuse. Patients suffer from severe and often intractable abdominal pain, maldigestion and diabetes, We have recently shown that gut toxins (endotoxins) may act as a trigger factor for pancreatitis in alcoholics. The proposed project aims to characterise the effects of gut toxins on the pancreas during alcohol abuse so as to identify pathways that may be therapeutically targeted to prevent or retard the disease.

Summary
Novel postsynaptic functions of the microtubule-associated protein tau. The protein tau is present in abnormal deposits in brains of individuals with dementia. The main aim of this project is to unravel and understand in detail new roles of tau in neurons and thus shed new light into normal brain function. Understanding these new functions of tau will aid in identifying new ways to treat these debilitating diseases.
