How do mechanical cues regulate tissue renewal and tumour progression? Imbalances between cell production and cell death in tissues can be catastrophic, leading to major global health issues such as cancer. This project will use modified mice and protein-protein interaction based techniques to identify how changes in the mechanical properties of tissues regulate the balance between cell production and cell death.

Summary
Three-dimensional cryo correlative light and electron microscopy facility. This project aims to establish a three-dimensional (3D) cryo-correlative light and electron microscopy facility. The facility will integrate light microscopy with high resolution cryo-electron tomography and 3D slice-and-view focused ion beam scanning electron microscopy. The open access facility should create new capabilities for Australian researchers to tag biological events and structures with fluorescence markers and ....Three-dimensional cryo correlative light and electron microscopy facility. This project aims to establish a three-dimensional (3D) cryo-correlative light and electron microscopy facility. The facility will integrate light microscopy with high resolution cryo-electron tomography and 3D slice-and-view focused ion beam scanning electron microscopy. The open access facility should create new capabilities for Australian researchers to tag biological events and structures with fluorescence markers and image them using the currently highest resolution 3D imaging techniques for biological matter. The facility expects to reveal fundamental insights into cell and structural biology, and help drive innovation in agriculture, pharmaceutics, and biomaterials.Read moreRead less
Molecular mechanisms regulating Ca2+ channels formed by Orai and STIM proteins. Store-operated calcium channels play a central role in the functions of all animal cells. They participate in generating the cellular responses to hormones, antigens, growth factors and other physiological stimuli. The aims of this project are to elucidate cellular mechanisms that regulate interaction between the molecular components of store-operated calcium channel, Orai and STIM. Using techniques of electrophysiol ....Molecular mechanisms regulating Ca2+ channels formed by Orai and STIM proteins. Store-operated calcium channels play a central role in the functions of all animal cells. They participate in generating the cellular responses to hormones, antigens, growth factors and other physiological stimuli. The aims of this project are to elucidate cellular mechanisms that regulate interaction between the molecular components of store-operated calcium channel, Orai and STIM. Using techniques of electrophysiology and molecular biology we expect to answer a fundamental question how STIM and Orai proteins interact to form functional store-operated calcium channels, and how the expression of STIM and Orai is regulated.Read moreRead less
Molecular hallmarks of androgen receptor targeting in prostate cancer. There is a critical need in oncology drug development for better biomarkers of response to prostate cancer therapies, clinically to assist with treatment decision making, and pre-clinically to facilitate translation of emerging agents into clinical practice. Using a unique explant culture model, this project will identify protein and lipid markers that can be used to accurately and reliably assess response to androgen recepto ....Molecular hallmarks of androgen receptor targeting in prostate cancer. There is a critical need in oncology drug development for better biomarkers of response to prostate cancer therapies, clinically to assist with treatment decision making, and pre-clinically to facilitate translation of emerging agents into clinical practice. Using a unique explant culture model, this project will identify protein and lipid markers that can be used to accurately and reliably assess response to androgen receptor (AR)-targeting therapies in human prostate tumours. The identification and functional assessment of these biomarkers will identify those that can be used as surrogate endpoints in clinical trials, facilitate earlier approval of investigational agents and lead to improved options for therapeutic management of prostate cancer.Read moreRead less
The transcriptional control of lymphatic vessel development. Lymphatic vessels are a vital, but often overlooked, component of the cardiovascular system. These specialised vessels return tissue fluid to the bloodstream, absorb dietary lipids and transport cells of the immune system throughout the body. Defects in the growth and development of lymphatic vessels result in disorders including lymphedema, obesity, inflammatory diseases and cancer. This project aims to define how transcription factor ....The transcriptional control of lymphatic vessel development. Lymphatic vessels are a vital, but often overlooked, component of the cardiovascular system. These specialised vessels return tissue fluid to the bloodstream, absorb dietary lipids and transport cells of the immune system throughout the body. Defects in the growth and development of lymphatic vessels result in disorders including lymphedema, obesity, inflammatory diseases and cancer. This project aims to define how transcription factors program lymphatic vessel identity and control the development of lymphatic vessel valves. This knowledge will provide new insight into the fundamental mechanisms by which the lymphatic vasculature is constructed during development.Read moreRead less
Transcription factor nuclear residency as a driver of gene expression. Persistently active proteins can stay in the nucleus to drive cell growth and prevent cell death. This project will define how one specific active protein can remain in the nucleus and regulate gene expression through the action of unique ribonucleic acid (RNA) molecules. The results will enable persistent gene activation to be manipulated in cancer.
The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.
Molecular dynamics of steroid receptor crosstalk. This project uses state-of-the-art technology to show how steroids (for example, testosterone) affect many aspects of human life, and how these can be disrupted by chemicals and synthetic hormones. The results can be used to interpret disease, predict safety of new drugs, and to monitor risk to humans and wildlife of environmental chemicals.
