Summary
Treating women with advanced breast cancer is difficult, and new drugs are needed to kill the cancer stem cells that cause recurrence. We think that a newly discovered protein, PKC-?, plays an important role in recurring breast cancer and can be targeted using novel ‘epigenetic’ drugs. Here, we will use cutting-edge DNA techniques to learn how this protein controls how cancer cells grow and produce the necessary data to show that targeting this protein is likely to be effective in real patients.
The dramatic increase in obesity and age-related metabolic disorders demonstrates the importance of gaining a better understanding of how cells and organisms regulate their energy stores. This project will identify novel molecular mechanisms that control the enzyme CaMKK2, which is a key regulator of whole-body energy metabolism. This will provide new opportunities to inform more effective strategies to tackle metabolic diseases, and improve health in an increasingly ageing population.

Summary
Humans have many internal asymmetries that need to occur in a consistent manner across all individuals. Examples of asymmetry include our unpaired organs (like the heart or liver) or a paired organ with asymmetry (like the lungs). In this project we will use cutting edge molecular embryology and cell biology techniques to explore the mechanisms behind the remarkable feat of establishing asymmetry so we are better able to help those individuals with laterality disorders.
Characterization Of SgK269, A Master Regulator Of Growth Factor Receptor Signalling

Summary
Perturbed signaling within a cell can cause multiple diseases, including cancer. SgK269 is a scaffold protein involved in signaling and implicated in breast, colon and pancreatic cancer. By determining the signaling mechanism and function of the SgK269 scaffold, this work will provide novel and important insights into a key regulator of cell signaling, and reveal potential strategies for therapeutic targeting of the SgK269 scaffold that could be utilized in cancer treatment.

Summary
Systemic lupus erythematosus is a disease where the immune system attacks normally healthy tissues. The spontaneous overproduction of signalling molecules called interferons in lupus plays an important role in the severity of the disease. We have found that two proteins, named Bcl6 and PLZF, are important in controlling the interferon response in lupus patients. We propose that identifying how these proteins act to control interferon will aid in developing new treatments for lupus.
Targetting The CIB1-sphingosine Kinase Interaction In Oncogenesis

Summary
Sphingosine kinase is a protein involved in cancer development and progression. We have identified that the cancer-inducing activity of sphingosine kinase is controlled by another protein called CIB1 which itself appears involved in causing cancer by deregulating sphingosine kinase. In this study we will examine and target the interaction between sphingosine kinase and CIB1 as a potential therapeutic intervention in cancer.
Retinoic Acid Receptor-related Orphan Receptors And The Regulation Of Metabolism:insights Into Diabetes And Obesity

Summary
Nuclear receptors (NRs) function as hormone dependent DNA binding proteins important in sustaining human health, highlighted by the array of medicines that target these proteins for human well being. ROR alpha is one such protein that we have shown regulates fat mass, obesity, and glucose tolerance. Obesity and diabetes are often linked with inflammation. We will examine how ROR controls inflammation during metabolic disease.
