Summary
Autologous chondrocyte implantation (ACI) is the ‘gold standard’ for treating knee cartilage defects. Traditionally, ACI was performed through open surgery. However, ACI can now be performed through ‘keyhole’ surgery, decreasing the co-morbidity of open surgery. Furthermore, optimal patient outcome is limited by a lack of knowledge in effective post-operative rehabilitation. This project will evaluate outcomes following ACI performed through keyhole surgery, in conjunction with 'accelerated' reh ....Autologous chondrocyte implantation (ACI) is the ‘gold standard’ for treating knee cartilage defects.

Summary
Arthritis is a major clinical and socio-economic problem. Arthritis involves the destruction of cartilage in joints. However, the mechanisms of initiation and progression of cartilage destruction remain poorly understood. Our studies will for explore the role of a new regulator of gene expression, microRNA, in the initation and progression of osteoarthritis. This will provide important new information on disease mechanisms for the development of diagnostic biomarkers and therapies
Three percent of children born in Australia are from IVF. It is typical in IVF to replace 2 or more embryos in order to attain an acceptable pregnancy rate. However, twin pregnancies are common as a result, with 25% of all twins coming from IVF. Twins represent a real medical issue for mother and infants. Therefore, this research will use new highly innovative technologies to determine the health of an individual embryo in the culture dish prior to transfer, making the selection and transfer of ....Three percent of children born in Australia are from IVF.

Manipulating Ovarian Follicle - Oocyte Communication To Control Reproductive Outcomes

Summary
Ovarian follicles provide the environment supporting oocyte (egg) development. Communication between cells of the follicle and oocytes modulate this environment. We discovered new cell surface molecules that receive the signals from the oocyte and we identified a class of drug compounds that can modulate this signalling. This discovery offers a unique potential to therapeutically intervene in this signalling process and both improve infertility therapies and develop new non-steroidal contracepti ....Ovarian follicles provide the environment supporting oocyte (egg) development.

Summary
Glucocorticoids (GCs) are widely used for their potent anti-inflammatory and immunomodulatory effects due to the effects GCs on immune cells or synovial fibroblasts. Recently, we have made the exciting discovery that arthritis mice with glucocorticoid receptor knock-out in chondrocyte are completely resistant to glucocorticoid treatment. This study will identify the mechanisms underlying these hormonal effects with the aim to find new targets for efficient treatments for arthritis.
Osteoarthritis (OA) affects approximately 20% of Australians and costs billions each year in joint replacements. Therapies that halt joint destruction in OA are urgently needed. We hypothesise that the little-known gene, vanin -3, is a key regulator of OA disease pathways. Our project will map vanin-3 in the joint and reveal how much vanin-3 contributes to joint destruction in mice. We expect to find a link between vanin-3 and metabolic disorders and identify new targets for therapy.
Femoroacetabular impingement (FAI) is a common cause of hip pain characterised by extra bone formation at the hip, called a cam-deformity. FAI is thought to create hip joint damage and osteoarthritis. Our 5 year longitudinal study of people with FAI in two (Melbourne and Brisbane) sites will investigate whether factors (such as cam-deformity size, hip contact force, muscle strength and joint range) can predict hip joint damage (measured with magnetic resonance imaging) over two years.
MicroRNAs As Therapeutic Targets For Osteoarthritis

Summary
microRNAs are small cellular RNA fragments that regulate protein expression. They have been shown to be crucial regulators of normal development and are associated with many disease processes. The goal of this project is to determine the role of microRNAs in the initiation and progression of joint degeneration in osteoarthritis and test the therapeutic efficacy of targeting microRNAs as new approach to OA treatment.
Investigating FABP4 As An Insulinotropic Adipokine

Funding Amount

Summary
Obesity is an epidemic: 1 in 4 Australian adults and 1 billion people on earth are obese, with diabetes, heart disease and cancer closely linked. Our study will reveal how the novel hormone Fatty acid binding protein 4 is released from fat and enhances pancreatic insulin secretion in response to obesity. This will explain how pathological increases in insulin levels occur during obesity (a longstanding conundrum) and provide new therapeutic targets with which to treat the disease.
Deciphering The Metabolic And Endocrine Profile Of Healthy Adipocytes

Funding Amount
$563,194.00
Summary
Obesity is associated with the development of metabolic diseases, however, it is becoming clear that it is where the excess fat is stored that is more important when predicting the health risks associated with obesity. This project aims to identify whether adipocyte progenitor cells, which eventually become fat cells, are ‘preprogrammed’ and whether differences in these cells explain the generation of either healthy or unhealthy fat in different locations of the body.
