Summary
When patients are treated in hospital with antibiotics they sometimes develop chronic diarrhoea or colitis syndromes that are very difficult and expensive to treat. This project involves the analysis of the bacterium that generally causes these gastrointestinal diseases. We know that this microorganism is present in the hospital environment and that it produces potent protein toxins that are responsible for these diseases but we know little about the actual disease process.

This project involves the analysis of the bacterium that generally causes these gastrointestinal diseases. We know that this microorganism is present in the hospital environment and that it produces potent protein toxins that are responsible for these diseases but we know little about the actual disease process. In most bacteria that cause disease there are regulatory networks that control the expression of the genes responsible for the disease process. In this project, we aim to develop an understanding of how these regulatory networks operate in this particular bacterium. The latest techniques of molecular biology will be used to investigate several specific regulatory genes at the functional level. Since the entire DNA sequence of this bacterium is now known we will also use a broader research approach that makes use of this knowledge to examine all of potential regulatory networks that exist in this bacterium. Finally, we will develop new methods for the genetic analysis of the causative bacterium so that we will be better able to elucidate the role of specific genes in the disease process. By understanding how this bacterium controls the production of the proteins that interact with human intestinal cells to cause disease we hope to be able to prevent such diseases from occurring. The successful completion of the project therefore will make a major contribution to the development of improved methods for the control and treatment of these chromic diarrhoea and colitis syndromes.Read moreRead less
Understanding The Molecular Heterogeneity Of Response And Resistance To Anti-HER2-ErbB2 Agents In Breast Cancer

Summary
A revolution in cancer care will take place in the next decade as we aim to individualize treatment for each patient. A subtype of breast cancer relies on a growth factor called HER2 for growth. Treatments that block HER2 are highly effective and have less side effects than chemotherapy. My study aims to further understand of the biology of this subtype of breast cancer and action of anti-HER2 agents as this will allow us to treat this aggressive type of breast cancer more effectively.
3'UTR switching in eukaryotic cells. The project aims to uncover conserved features fundamental to the mechanism and function of post-transcriptional gene-expression control. RNA systems interface the executive functions of DNA and the worker functions of proteins. mRNA often dictates the level, timing and location of protein synthesis. This project will use RNA-sequencing and bespoke bioinformatics to probe global RNA-dynamics.

The project aims to uncover conserved features fundamental to the mechanism and function of post-transcriptional gene-expression control. RNA systems interface the executive functions of DNA and the worker functions of proteins. mRNA often dictates the level, timing and location of protein synthesis. This project will use RNA-sequencing and bespoke bioinformatics to probe global RNA-dynamics. Mixing yeast-genetics with RNA-technologies, it focuses on 3’ untranslated region (UTR) dynamics in eukaryotic cell biology. This project expects to significantly advance the understanding of eukaryotic gene function and gene regulation, critical in an age of personalised genomic medicine.Read moreRead less

Summary
Despite recent advances, approximately one third of subjects with type 1 diabetes develop kidney disease and similar proportion develop vision-threatening eye disease. Indeed, in many instances eye and kidney disease occur in the same individual. The central aim of this proposed Special Program is the exploration of mechanisms that lead to the development and progression of these devastating complications of type 1 diabetes with a particular focus on novel strategies, directly applicable to man, ....Despite recent advances, approximately one third of subjects with type 1 diabetes develop kidney disease and similar proportion develop vision-threatening eye disease. Indeed, in many instances eye and kidney disease occur in the same individual. The central aim of this proposed Special Program is the exploration of mechanisms that lead to the development and progression of these devastating complications of type 1 diabetes with a particular focus on novel strategies, directly applicable to man, for their prevention and treatment. Participants in Special Program include both established diabetes researchers and investigators from other areas of academia (blood vessel biology and applied genetics). Strong interrelationships between the various investigators and their departments already exist and will be further consolidated with continued collaboration, sharing a combination of models, novel interventions and complex genetic techniques that would not be possible outside of a large collaborative framework. In addition to academic collaboration, interactions with industry-based drug discovery programs is also an important component in developing new treatment strategies for diabetic kidney and eye disease. The Special Program will thus consist of a range of studies of direct relevance to diabetic kidney and diabetic eye disease in humans. It is expected that these studies will lead to new strategies for the prevention, treatment and even the reversal of long term complications of diabetes.Read moreRead less
