How IGFBP-3 improves cancer cell responsiveness to DNA-damaging therapies. A protein called IGFBP-3 can modulate the way cancer cells respond to treatments such as radiotherapy and certain chemotherapy drugs. These therapies, which act by damaging cells' DNA, play an important role in the treatment of many cancers, but their effectiveness is limited by the ability of cells to oppose the treatment by repairing damaged DNA. This project aims to discover how IGFBP-3 acts to change cancer cells' res ....How IGFBP-3 improves cancer cell responsiveness to DNA-damaging therapies. A protein called IGFBP-3 can modulate the way cancer cells respond to treatments such as radiotherapy and certain chemotherapy drugs. These therapies, which act by damaging cells' DNA, play an important role in the treatment of many cancers, but their effectiveness is limited by the ability of cells to oppose the treatment by repairing damaged DNA. This project aims to discover how IGFBP-3 acts to change cancer cells' response to treatment, using breast cancer cells growing in culture as a model system. This work has the potential to lead to improvements in the treatment of cancer patients by increasing our understanding of what happens when cancer cells are exposed to radio- or chemotherapy.Read moreRead less
A New Model for 3D Migration Involving Claw Structures and Metalloproteinases. This proposal will revolutionize ideas related to cell movement through three-dimensional (3D) matrix. Our method in mimicking the body's dense 3D matrix environment have led to the discovery of a new cell structure called Claws, and the formulation of a new model for 3D invasion in high density matrix. We will study the genes that control this type of migration including those involved in the formation of the cell fr ....A New Model for 3D Migration Involving Claw Structures and Metalloproteinases.

This work will have significant impact on normal and pathological human conditions from immune responses to tissue regeneration and cancer.Read moreRead less
Tissue specific regulation of gene expression. Despite the polarized public debate concerning the use of stem cells for tissue regeneration, fundamental questions relating to the identity and hierarchy of these cells remain unanswered. The benefit to Australia will be scientific in terms of providing an understanding of how stem and progenitor cells integrate transcriptional control systems during differentiation and the networks that are involved. This is fundamental to the future isolation a ....Tissue specific regulation of gene expression. Despite the polarized public debate concerning the use of stem cells for tissue regeneration, fundamental questions relating to the identity and hierarchy of these cells remain unanswered. The benefit to Australia will be scientific in terms of providing an understanding of how stem and progenitor cells integrate transcriptional control systems during differentiation and the networks that are involved. This is fundamental to the future isolation and manipulation of these stem cell types to benefit the community. The work will also provide postgraduate students with training in state of the art genomic techniques and in the interface between bioinformatics and experimental science. Read moreRead less
Function of a new splicing factor, RBM4. New genomic knowledge is revolutionizing our world. However our understanding of the basic mechanisms of RNA maturation, especially regulation of splicing lags significantly behind our understanding of related genomic processes.

However our understanding of the basic mechanisms of RNA maturation, especially regulation of splicing lags significantly behind our understanding of related genomic processes. This project is a genetic approach to help elucidate the function of new splicing factors and characterize the way in which specific RNA sequences are recognized. It should promote the better understanding of regulatory events involved in controlling gene expression during development and differentiation. Results from this project will also provide new insights into the 'multifunctionality' of cellular proteins and will illustrate the importance of RNA studies in molecular medicine.Read moreRead less
