Every cell in our body has an intrinsic orientation that is controlled by a universal set of genes known as polarity genes. Loss of this orientation is a common and early feature of cancer. We have identified the gene Scribble as a gene that controls cell orientation and is essential to prevent the development of prostate cancer. We propose experiments to discover how Scribble controls prostate cancer and whether it can be used to better predict outcome for prostate cancer patients.

Summary
Cataract extraction is the most common surgical procedure conducted in our hospitals today. Unfortunately, a complication of surgery is the development of a secondary cataract. This is caused by residual lens epithelial cells undergoing a wound healing response that leads to severe scarring and loss of vision. This project will identify the factors that are needed to maintain lens epithelial cells in a normal state so that they can act as stem cells that can be induced to regenerate a new lens t ....Cataract extraction is the most common surgical procedure conducted in our hospitals today.

This is caused by residual lens epithelial cells undergoing a wound healing response that leads to severe scarring and loss of vision. This project will identify the factors that are needed to maintain lens epithelial cells in a normal state so that they can act as stem cells that can be induced to regenerate a new lens that can transmit and focus light as normal.Read moreRead less
Genetic variation of single cell transcriptional heterogeneity in HiPSCs. This project aims to investigate whether induced pluripotent stem cells (iPSC) can be used to study the functions of genetic variants associated with human phenotypes and cell fate decisions. The project will utilise technology to produce single cell RNA sequence data for 100,000s of cells. By sequencing individual cells, the genetic control of cellular heterogeneity both within and between cells can be identified, and in ....Genetic variation of single cell transcriptional heterogeneity in HiPSCs.

The project will utilise technology to produce single cell RNA sequence data for 100,000s of cells. By sequencing individual cells, the genetic control of cellular heterogeneity both within and between cells can be identified, and in doing so, will provide significant benefit by revealing the potential for iPSC to be used for functional translation of human genomics.Read moreRead less

Summary
Cancer initiating cells acquire stem cell characteristics and multiply within a supportive environment that helps maintain and propagate malignant cells. Identifying the normal hierarchy of gene control within blood stem cells and designing therapies that target cancer cells is the ultimate goal of this body of work.
Investigating Hippo-regulated transcription at single molecule resolution. Signalling pathways operate throughout life to relay signals from the extracellular world to the cellular nucleus, to control transcription and elicit a response. This project aims to understand how the Hippo growth control pathway regulates transcription. Using a combination of biology, biophysics and computational biology, this project aims to quantify behaviour of the Hippo pathway transcription factors at sub-micron r ....Investigating Hippo-regulated transcription at single molecule resolution. Signalling pathways operate throughout life to relay signals from the extracellular world to the cellular nucleus, to control transcription and elicit a response. This project aims to understand how the Hippo growth control pathway regulates transcription. Using a combination of biology, biophysics and computational biology, this project aims to quantify behaviour of the Hippo pathway transcription factors at sub-micron resolution, and how Hippo signalling modulates their behaviour, interaction with the genome and function. We anticipate our discoveries will stimulate new research, e.g. testing of how other signaling pathways regulate transcription. Intended benefits are creation of jobs and new knowledge on fundamental principles of life.Read moreRead less
How neurons maintain their fate. This project aims to investigate how neurons maintain their identity, without reverting back to less specialised cells. Stable fate maintenance is essential because when it fails, cells lose their ability to perform their ascribed function, which impedes organism fitness. This project aims to define how two proteins work in partnership to maintain the identity of brain neurons. We intend our discoveries to stimulate new research, for example to test whether the h ....How neurons maintain their fate. This project aims to investigate how neurons maintain their identity, without reverting back to less specialised cells. Stable fate maintenance is essential because when it fails, cells lose their ability to perform their ascribed function, which impedes organism fitness. This project aims to define how two proteins work in partnership to maintain the identity of brain neurons. We intend our discoveries to stimulate new research, for example to test whether the human counterparts of the Drosophila proteins studied here, function similarly. Benefits will be provided in the form of job creation, and new knowledge in fundamental aspects of life, including brain development and cell fate maintenance.Read moreRead less

Summary
Identifying molecular regulators of haematopoietic stem cell development. Blood stem cells are capable of making all types of mature blood cell whilst making new copies of themselves. These properties are essential for the life-long supply of blood and make stem cells ideal for therapeutic use. By studying embryos, this project will identify genes that control the production and expansion of blood-forming stem cells.

The Hippo signalling pathway in dividing and non-dividing cells. This project aims to understand how the Drosophila Hippo pathway performs two very different jobs in the same organ, that is control cell proliferation and differentiation. The redeployment of cellular machinery to do different jobs is very common and efficient, but the mechanism by which this occurs is poorly understood. Using new techniques, this project aims to provide new knowledge to several fields including organ growth contr ....The Hippo signalling pathway in dividing and non-dividing cells.

Molecular function of the ribonucleic acid binding protein RBM47 in embryonic and mature endoderm cells. This project aims to test the hypothesis that a novel ribonucleic acid (RNA) binding protein, called RBM47, regulates the processing of the RNA transcripts of genes. This project will reveal the identity and the function of these genes that are essential for controlling the growth of the embryo and the organism after birth.
