Identification of novel biomarkers in tears for prostate cancer diagnosis and prognosis. The purpose of this study is to identify novel biomarkers in the tears of patients with CaP. The use of the several techniques will increase the chance of success and enable us to find more diagnostic markers. If successful, the identified proteins may be used to diagnose and determine the stage of cancer. This will help guide clinicians in choosing the best treatment methods for an individual patient.

The use of the several techniques will increase the chance of success and enable us to find more diagnostic markers. If successful, the identified proteins may be used to diagnose and determine the stage of cancer. This will help guide clinicians in choosing the best treatment methods for an individual patient. The markers may also be used to monitor the disease progress and the effects of treatment. The results from this study may improve the prognosis of CaP patients.Read moreRead less
Novel approaches for structural and functional analysis of the protein complex COG, a tether that controls intra-Golgi trafficking. Production and engineering of proteins are key methodologies of the life sciences in general and biotechnology in particular. Our ability to produce and analyse protein-based components of the cell determines the expense and speed of discovery, as well as the creation of new vaccines, drugs, and diagnostic methods. The current project aims to develop new approaches ....Novel approaches for structural and functional analysis of the protein complex COG, a tether that controls intra-Golgi trafficking.

NmlR-dependent thiol-based redox systems and their role in global stress responses in bacteria. All cells sense changes to their environment and respond by altering their metabolism. A major environmental change is oxidative stress which damages cells. Cells have the ability to sense oxidative stress and alter metabolic processes to defend against the damage that it elicits. This proposal will characterize a novel oxidative stress defense system that is found in a number of bacterial pathogens t ....NmlR-dependent thiol-based redox systems and their role in global stress responses in bacteria. All cells sense changes to their environment and respond by altering their metabolism. A major environmental change is oxidative stress which damages cells. Cells have the ability to sense oxidative stress and alter metabolic processes to defend against the damage that it elicits. This proposal will characterize a novel oxidative stress defense system that is found in a number of bacterial pathogens that need to defend themselves against attack by the host. The project may identify new ways to manage these bacterial pathogens. It may also provide an insight into oxidative stress defense processes that are linked to pathologies in humans.Read moreRead less
The role of human single stranded DNA binding protein 1 in the repair of stalled DNA replication forks. It is vital that human cells protect their genetic code in order to prevent cancer. This project will look at how cells do this, with the aim of finding new ways to protect us from cancer.

Summary
Facility for multidimensional fractionation of complex biological mixtures. Acquisition of multidimensional fractionation equipment will allow researchers to separate proteins from complex mixtures, and to compare whole protein profiles of multiple samples. This will permit correlation of specific protein changes associated with infection or disease, a major focus of post-genomic programs of research. The equipment will also provide identification of the key differentiating proteins using mini ....Facility for multidimensional fractionation of complex biological mixtures. Acquisition of multidimensional fractionation equipment will allow researchers to separate proteins from complex mixtures, and to compare whole protein profiles of multiple samples. This will permit correlation of specific protein changes associated with infection or disease, a major focus of post-genomic programs of research. The equipment will also provide identification of the key differentiating proteins using minimal material. Numerous world-class projects and researchers will be able to move more rapidly and reliably from crude cell extracts to identifiable markers, and maintain their competitive positions the recognition of key targets in drug design, disease diagnosis and vaccine development.Read moreRead less

Summary
A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are prote ....A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are proteins, interacting with each other and with signal molecules. The next frontier in molecular biology is to identify and quantify these protein interactions. Our two institutions have a very large cohort of biologists whose research on proteins would be greatly facilitated by the Biacore 3000 and the ISS K2.Read moreRead less
Proteomics Analysis of Interactions Between Chaperonin 10 and Cell Surface Proteins. Specific interactions at the cell surface may induce downstream biological responses. In the case of chaperonin 10, Cpn10, interaction at the cell surface results in immunomodulation of the inflammatory response. Cell surface proteins that interact with Cpn10 have not been identified. This project will use chemical crosslinking and proteomic techniques to identify cell surface proteins that interact with Cpn10 a ....Proteomics Analysis of Interactions Between Chaperonin 10 and Cell Surface Proteins. Specific interactions at the cell surface may induce downstream biological responses. In the case of chaperonin 10, Cpn10, interaction at the cell surface results in immunomodulation of the inflammatory response. Cell surface proteins that interact with Cpn10 have not been identified. This project will use chemical crosslinking and proteomic techniques to identify cell surface proteins that interact with Cpn10 and structural features of Cpn10 involved in these interactions. These findings will providde leads for the development of immunomodulatory therapeutics based on Cpn10 interactions. Analytical technologies will be developed that are applicable to other interacting protein systems.Read moreRead less

The protein import machinery of peroxisomes. The peroxisome is a subcellular organelle essential for cellular metabolism. Our understanding of the formation, or biogenesis, of the peroxisome has advanced to the stage where many of the proteins involved in this process have been identified. What is less clear is how these proteins interact to form functional macromolecular complexes in the cell. In this project we will use biochemical approaches to isolate protein complexes involved in peroxisome ....The protein import machinery of peroxisomes.
