Bone Growth For Healthy Development: Physiology, Pathophysiology, And Regeneration

Funding Amount

Summary
Musculoskeletal damage is a major burden on individuals and our health care system. My research program will focus on improving bone health in three important areas: (1) children’s growth plate injury and growth defects; (2) bone loss and bone marrow defects from cancer chemotherapy; (3) ensuring that bone grows healthily in early life. The overall intent of this research is to develop new therapies when bone doesn’t grow well, or is damaged.
The Central Role Of The Osteocyte In Skeletal Pathophysiology

Funding Amount
$638,517.00
Summary
Bone diseases affect more people than any other group, carry a huge and growing socioeconomic cost, yet their aetiologies are not fully determined. This study will elucidate the role of the resident bone cell, the osteocyte, in prevalent bone diseases such as osteoporosis, osteoarthritis and related orthopaedic conditions, rheumatoid arthritis, bone cancer, and in systemic metabolism. The goal is to provide the knowledge and mechanisms for developing improved treatments and patient outcomes.
Assessment Of The Properties Of Mesenchymal Stem Cells And Their Role In Skeletal Tissue Repair And Disease

Summary
There is currently a steady increase in surgical intervention and rehabilitation therapy for bone related fractures due to trauma or osteoporosis as a consequence of an aging population. Bone regeneration involves the coordinated participation of skeletal precursor cells, blood vessels and immune cells recruited from the surrounding tissues. This proposal examines the mechanisms mediating the maintenance and recruitment of skeletal precursor cells to sites of bone damage.
Regulation Of Normal And Malignant Haematopoiesis By The Bone Marrow Environment

Summary
This project will identify factors within the bone marrow that regulate blood and immune cell formation. These include oxygenation and novel proteins identified in the applicant’s laboratory. How these factors from the bone marrow influence the behaviour of normal blood forming cells (called haematopoietic stem cells), and the progression of leukaemia and the response of leukaemia to chemotherapy treatments will be investigated. New drugs that interfere with these new factors will be tested for ....This project will identify factors within the bone marrow that regulate blood and immune cell formation.

I am a biochemical geneticist working on inherited disorders that affect the musculoskeletal system. My major focus is determining the molecular basis of muscular dystrophies and bone and cartilage disorders.
Tissue Engineering Approach To Musculoskeletal Regeneration

Funding Amount
$622,655.00
Summary
Over the next few decades there is an anticipated steady increase in surgical intervention for bone, cartilage and tendon damages due to trauma or osteoporosis as a consequence of an aging population. These damages cause chronic pain, immobility, restricted activities, and, sometimes, death and are a considerable financial burden to the Australian Health System.
Optimising Benefits And Minimising Potential Harms Of Obesity Treatments
Funder
National Health and Medical Research Council
Funding Amount
$707,370.00
Summary
This work aims to find safe and more effective obesity treatments for the over 2.1 billion people worldwide with overweight or obesity. Severely energy restricted diets are currently the most effective dietary obesity treatment, but these are underutilized due to concerns about potential harms. This work will investigate using severe diets intermittently rather than continuously, as a means of enhancing their benefits of long-term weight/fat loss while also reducing potential harmful effects.
Development Of Novel Resorbable Biomaterials For Regeneration Of Human Tissue

Funding Amount
$601,484.00
Summary
Large skeletal defects resulting from congenital defects or disease processes are difficult to regenerate and represent a major financial burden to our health system. Bone graft treatments are widely used but have considerable drawbacks. Available synthetic alternatives lack the physical/biological properties necessary. We have developed new scaffolds with improved mechanical/biological properties for bone and cartilage regeneration.
High Protein, Low Glycemic Load Weight Loss Diets In Type 2 Diabetes
Funder

Funding Amount
$906,928.00
Summary
High protein, low glycemic load weight loss diets have the potential to be of value in long term weight control but there is little long term data available. There is also some uncertainty about the long term safety of high protein diets and this needs clarification in long term trials. As compliance to the diet is the major issue in long term trials we will explore new ways of getting people to stay in long term studies and maintain a calorie reduced diet.
Improving Weight Loss Outcomes By Minimizing Adaptive Responses To Energy Restriction

Summary
While losing excess weight reduces the risk of lifestyle diseases such as diabetes, current weight loss strategies are ineffective for most, in part because the body mounts a ‘famine reaction’ that increases hunger, decreases metabolic rate and may also cause loss of muscle and bone mass. This research aims to determine the effects of the famine reaction on body composition, as well as to identify new ways to block the famine reaction with food, thereby enabling more people to attain and maintai ....While losing excess weight reduces the risk of lifestyle diseases such as diabetes, current weight loss strategies are ineffective for most, in part because the body mounts a ‘famine reaction’ that increases hunger, decreases metabolic rate and may also cause loss of muscle and bone mass.
