Summary
Regulation of B cell differentiation, which occurs when our body responds to antigen infection is tightly controlled by a gene regulatory network. This project will be the first study to reconstruct a regulatory network for this process by using genome-wide expression and transcription factor binding data. The research finding from this study will elucidate the molecular mechanisms regulating this process and will shed new light on how this network is altered in lymphoma and myeloma.

Summary
In Multiple Sclerosis (MS), the immune system repeatedly attacks the brain and spinal cord. In the last three years, rapid progress has been made in understanding genetic risk factors for MS, and more than 20 are known, but their function is not understood. The proposed study will recruit patients with MS and healthy controls to isolate five major immune cell types, and will assess how risk genes influence these cells. We hope to obtain a much better picture of how genetic risk factors for MS ac ....In Multiple Sclerosis (MS), the immune system repeatedly attacks the brain and spinal cord.

Glioblastomas are the most common and lethal brain tumours and 5 years after diagnosis only 20% of patients diagnosed with a glioblastoma will be alive. The poor survival rate is due to the ability of these tumours to extensively penetrate into the surrounding healthy brain tissue making complete surgical removal very difficult. Our research aims to discover how the glioblastoma cells can penetrate neighbouring brain tissue.

Summary
The mechanisms required for breast cancer cells to spread outside of the ducts and into the surrounding breast tissue are largely unknown. There is increasing evidence that the cell layer surrounding the ducts (myoepithelium) functions to suppress invasion. We aim to test if a protein inhibitor that is expressed in these cells can preventing breast cancer invasion in models of early breast cancer and if its expression can predict those patients that are unlikely to develop invasive cancers.
Defining The Role Of Microphthalmia-associated Transcription Factor (MITF) In Melanoma Heterogeneity By Real-time Cell Cycle Imaging

Summary
Metastatic melanoma is highly therapy-resistant. Modern targeted therapy is promising but suffers from rapid onset of drug resistance. Tumours consist of zones of fast growing cells next to zones of dormant cells. This tumour heterogeneity is one of the reasons for cancer drug resistance, as cells in different growth states respond differently to drugs. By understanding the causes of tumour heterogeneity we will set the basis for innovative clinical approaches against this devastating disease.
Evaluation Of Molecular Mechanisms Driving Metastasis Using Integrated Intravital Imaging

Summary
Metastasis is the leading cause of cancer-associated death. Understanding key steps that drive the spread of cancer is critical to improve current treatment strategies. Using cutting-edge imaging technology and 3-dimensional model systems that mimic the disease, we will pinpoint key events that are susceptible to drug intervention and identify new therapeutic targets.
Retargeting The Antibiotic Azithromycin As An Antimalarial With Dual Modality.

Summary
Malaria parasites resistant to first-line treatments continue to spread in South East Asia. New drugs need to be developed urgently to ensure alternative treatment strategies are available. We will retarget the safe and widely used antibiotic azithromycin as an antimalarial with dual modalities against parasite invasion and growth inside the host red blood cell. This strategy has significant potential to increase drug efficacy while reducing the chances for the development of resistance.
An unusual type of molecule, circular RNA, was recently discovered to be present in human cells, and to potentially affect the ability of cancer cells in invade and metastasise. We will investigate the interactions these circular RNA molecules have with other molecules, what functions they have, and how they affect cancer cell invasion and metastasis. This could potentially reveal new ways of intervening in cancer metastasis, leading to new therapeutic modalities for cancer patients.
New Role For The E3 Ligase E6AP In The Control Of Cell Motility And Invasion

Summary
Cell motility and invasion are fundamental process in normal cellular functions, however, when deregulated they can lead to metastatic cancer, a leading cause of cancer mortality and morbidity worldwide. Detailed understanding of the mechanisms governing these processes is essential for the development of new targets to prevent metastatic cancer. We discovered a protein that control these processes, which renders it an important target to investigate.
Investigating A Novel Genetic Regulator Of Cardiac Rhythm

Summary
Cardiac arrhythmias affect approximately 5% of the population and have a high association with sudden death. Whilst the cause of cardiac arrhythmia is complex, we know that genetic mutations play a role however we don't know all the genes important for cardiac rhythm. It is imperative that we identify all the genes in this process, so we can determine which mutations cause arrhythmia. We have identified a new gene that causes cardiac arrhythmia and seek to understand how it functions.
