Summary
A promising class of cancer drugs target heat shock protein 90 (Hsp90) and prevent Hsp90 from maintaining its ~100 proteins involved in cell growth. However, all current Hsp90 chemotherapeutics non-selectively target proteins maintained by Hsp90, and induce a cell rescue mechanism involving Hsp70. We describe the development of a novel molecule that will selectively control cell growth and prevent cell rescue via a unique Hsp90 regulated mechanism.

Summary
Apoptosis is a form of cell suicide that is vital in human development and health by removing damaged or unwanted cells in a regulated manner. Disturbances in this pathway are known to be the cause of cancers and other diseases. This research will investigate how the pivotal step in cell death, termed mitochondrial outer membrane permeabilisation (MOMP) is regulated.

Summary
Within the cell nucleus, specific proteins weave DNA into structured loops that are vital for normal cell function. By studying the molecules involved, we have uncovered a ‘dock’ that controls this DNA architecture. We will define the components and function of this ‘dock’, and the resulting rapid cell death that occurs if it is disrupted. We will explore this cell death pathway thoroughly because we think it may help us to develop new cancer therapies.

Summary
The death of cells of our body can be an active and purposeful process. Programmed death occurs in response to infection or as a defence against cancerous changes. If a virally infected cell can die prior to replication of the virus, this will control the infection. We have investigated cell death in response to DNA found in the cytoplasm of cells, which can be an indication of infection. The novel cell death pathway we are characterising is relevant to defence against infection and tumours.

Summary
Impaired cell death (apoptosis) is now recognized as an important step towards cancer and a major barrier to effective therapy. The discoveries on apoptosis by Professor Jerry Adams and colleagues have galvanized the search for drugs that engage the cell’s apoptotic machinery as a new way to treat cancer. His proposed studies aim to clarify how apoptosis is controlled and how the control goes awry in cancer, and to determine how such drugs can be most effectively used to improve cancer treatment ....Impaired cell death (apoptosis) is now recognized as an important step towards cancer and a major barrier to effective therapy.

Summary
In cancer cells the normal process of cell death (called apoptosis) is defective, helping abnormal cells to grow and multiply unchecked. The Bak and Bax proteins are members of the Bcl-2 family of apoptosis regulators, and play a pivotal role in mediating cell death. By defining how these proteins form a pore in mitochondria, the point of no return in cell death, will help the development of novel anti-cancer agents that target the Bcl-2 family in general, and Bak and Bax in particular.
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
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.

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

Summary
Understanding the factors regulating blood production is critical to understanding how blood cancers occur and for the development of new therapies. Evidence is emerging of a vital role for the evolutionary conserved ‘polarity’ proteins in blood production and leukaemia This project will elucidate the role of the polarity protein, Par3, in normal and malignant blood cells, providing valuable insight into how Par3 regulates blood formation and the onset and severity of leukaemia.
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 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
