Summary
PLZF and SALL4 are critical stem cell factors and mutations in these genes are associated with developmental defects and cancer. SALL4 mutations are responsible for the malformation disease Duane-radial ray syndrome, while PLZF mutations lead to severe defects in the skeleton and gonads. We surprisingly found that PLZF and SALL4 interact and oppose each other’s functions. Our study of PLZF–SALL4 crosstalk will provide important insight into infertility, developmental disorders and cancer.
Deciphering The Metabolic And Endocrine Profile Of Healthy Adipocytes

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.
Comparison Of Periodontal Ligament Stem Cells And Induced Pluripotent Periodontal Ligament Stem Cells For Periodontal Regeneration

Funding Amount
$831,955.00
Summary
In the first part of this study we will determine whether induced pluripotent stem cells or adult stem cells from the periodontal ligament are better candidates for periodontal regeneration. Secondly, using CAD/CAM technology we will make tissue engineering scaffolds tailored to fit periodontal defects and seeded with stem cells to improve on current techniques used to regenerate damaged tissues around teeth affected by periodontal disease.
Investigating Human Keratinocyte Stem Cells And Their Microenvironmental Niche

Summary
The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue. However, this tissue regenerative ability can be enhanced by interactions with microenvironmental elements i.e. connective tissue cells and proteins. This study seeks to investigate specific keratinocyte-microenvironment interactions which will ultimately be used to improve current methods for generating skin tissue for burns patien ....The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue.

Osteochondroreticular Stem Cell Therapy For Osteoarthritis: The Right Cells For The Job.

Summary
"Wear and tear" arthritis of the knee, hip and back joints is known as osteoarthritis. This causes significant health burden and costs in our community, particularly in older Australians. Osteoarthritis begins with the loss of joint cartilage. We believe that a new type of stem cells (OCR stem cells) offer the greatest promise to generate and thus therapeutically replace joint cartilage. Our studies test this hypothesis and develop preclinical translation of our discoveries in mice into humans.
RZR-alpha In The Control Of Proliferative Vascular Disease

Funding Amount
$521,706.00
Summary
Four million Australians have cardiovascular disease accounting for 35% of all deaths. CVD is the most expensive disease burden and a National Health Priority. Smooth muscle cell growth is a cause of CVD. However, the mechanisms controlling SMC hyperplasia are poorly understood. This project will provide key insights on the role of RZR-alpha in the pathogenesis of blood vessel disease, and develop novel gene-targeting approaches for new opportunities to control complications of CVD.
Transcriptome Landscape Of Brown/beige Adipogenesis In Humans
Funder
National Health and Medical Research Council
Funding Amount
$393,369.00
Summary
There are three kinds of fat in the body: white, brown and beige. While excess white fat results in obesity, brown fat is associated with leanness and lowers blood glucose levels. Recent animal experiments show that under certain conditions, white fat can be transformed into beige fat, leading to benefits such as weight loss. The current project grant involves examination of human fat cells grown in the laboratory and investigation on the genetics of brown and beige fat.
Therapeutic Potential Of Transforming Growth Factor-beta Proteins For The Diagnosis And Treatment Of Female Infertility

Funding Amount
$942,961.00
Summary
We discovered and manufactured a growth factor produced uniquely by the egg. We named this growth factor cumulin. It is a powerful regulator of ovarian function and egg quality. This project will study the basic mechanisms of how cumulin works in the ovary. We will then develop an assay to measure it as a biomarker of human egg quality and quantity. New approaches in fertility preservation for cancer survivors will be developed using cumulin.
Mapping The TNF Pathway: A Qualitative And Quantative Molecular Analysis Of The Components And Post-translational Modifications Involved In Physiological And Pathological TNFR1 Signalling

Funding Amount

Summary
TNF is a master regulator of the inflammation response and dysregulated TNF signalling causes many human diseases. We will use a cutting edge mass spectrometry technique that we have developed to analyse molecules required for TNF signalling. Understanding how the TNF signalling works in all cell types and with different forms of ligands will open up therapeutic opportunities to selectively target TNF signalling in inflammatory diseases, such as Rheumatoid Arthritis and Cancer.
Activation Of GDF9 Regulates Human Folliculogenesis

Funding Amount
$531,690.00
Summary
GDF9 is a key regulator of fertility in female mammals, as it controls the process of folliculogenesis. In this grant, we will demonstrate the importance of GDF9 in human folliculogenesis, determine the mechanisms that activate GDF9 and show why aberrant GDF9 activation leads to ovarian disorders. Collectively, the outcomes of this proposal will increase our understanding of the fundamental mechanisms that regulate ovarian folliculogenesis and provide new avenues to manipulate this process.
