Cancer arises through a combination of common DNA mutations which are associated with very poor survival in certain cancers. However, the cause of these mutations was always believed to be external factors (eg. UV light, toxins), Our exciting preliminary results show internal molecules, called circular RNAs, can drive these mutations and this project will investigate how this occurs and study whether targeting these molecules can reduce the incidence of cancers.

Summary
Circular RNA molecules were recently found to be present in human cells, but their functions are largely unknown.We have discovered that the production of circular RNAs is changed during the differentiation process known as epithelial to mesenchymal transition, which is linked to cancer metastasis. We will investigate the functions of circRNAs, how their formation is controlled, and whether the circRNAs have a role in cancer progression.
Splice Correction As A Treatment For Rare Diseases

Summary
We propose that a strategy of bringing effective and personalised treatments to amenable patients with rare genetic diseases, though ambitious, is readily achievable and opportune. Importantly, a consensus approach will facilitate expediting potentially curative treatments for many patients with rare diseases that would be unlikely to be commercially viable if considered individually.

Summary
microRNAs are gene regulators with critical roles in heart disease. How interactions between microRNAs and their messenger RNA targets change during disease is poorly understood. We hypothesise that these interactions are critically affected by altered processing of microRNAs and targets. We will thus characterise and validate such differences in healthy and diseased hearts. This will define gene regulatory changes underpinning heart disease and contribute to the search for better treatment.

Summary
Now that the human genome has been sequenced, we can see that a human being is defined bye approximately 30000 genes. One of the biggest surprises to come from this work was that the number of genes was significantly smaller than many predicted. Similar surprise was registered at the discovery that the genome of the fruit fly actually contained fewer genes than that of the model worm, Caenorhabditis elegans. Part of the explanation for these apparent discrepencies lies in the phenomenon known as ....Now that the human genome has been sequenced, we can see that a human being is defined bye approximately 30000 genes. One of the biggest surprises to come from this work was that the number of genes was significantly smaller than many predicted. Similar surprise was registered at the discovery that the genome of the fruit fly actually contained fewer genes than that of the model worm, Caenorhabditis elegans. Part of the explanation for these apparent discrepencies lies in the phenomenon known as gene splicing, whereby one gene can actually give rise to many different isoforms of the same protein. These different isoforms can have different structures and-or functions, and dramatically increase the complexity that it is possible for an organism to achieve with a given number of genes. The process of splicing is very intricate, requiring precise control to allow an organism to develop normally. Many human genetic diseases are known to arise from problems with splicing. However, our understanding of the mechanisms of splicing is rather incomplete. This proposal aims to improve our understanding of the splicing process through a range of biophysical and molecular biological approaches. This information should prove useful in understanding human development and disease.Read moreRead less
Characterising Novel Alternative Splicing Networks That Promote Tumour Cell Plasticity

Summary
During cancer progression, tumour cells can change their properties and become more aggressive and resistant to therapies. We have identified an important regulator of this tumour cell transition, called “Quaking”, which causes widespread changes in gene splicing. We aim to investigate how "Quaking" causes changes in gene splicing and what the effects of these splicing changes are in tumour cells.

Summary
Our project will shed light on the development of white blood cells, and what goes wrong when they become cancerous. In particular we have uncovered an unexpected control mechanism of gene expression in these cells. This mechanism governs the specific removal of molecules involved in transmitting information in cells (mRNAs). By extending our research to a cancer of white blood cells called chronic myeloid leukaemia, we hope to provide new insights into its causes and discover targets for innova ....Our project will shed light on the development of white blood cells, and what goes wrong when they become cancerous.
