Investigation of the mechanisms underlying successful placentation. The overall aim of this project is to provide novel insights into the basic cellular processes that underpin placental development and to improve our ability to manipulate mammalian reproduction, both human and animal. The placenta is critical for intrauterine development because it determines the level of nutrition, oxygenation and maternal tolerance to the developing foetus. The project intends to explore the role of prorenin ....Investigation of the mechanisms underlying successful placentation. The overall aim of this project is to provide novel insights into the basic cellular processes that underpin placental development and to improve our ability to manipulate mammalian reproduction, both human and animal. The placenta is critical for intrauterine development because it determines the level of nutrition, oxygenation and maternal tolerance to the developing foetus. The project intends to explore the role of prorenin and its receptor as a novel mechanism driving placentation. Applications for expected project outcomes may include improved breeding of threatened animal species and economically valuable domestic animals as well as improved health care and fertility control for domesticated pets and feral animals.

Unravelling a canonical mitochondrial stress response pathway. Stress has a major impact on all life forms and is considered one of the key determinants of healthy ageing. This project aims to unravel a highly novel pathway through which many different forms of stress converge to induce a conserved stress response in mammalian cells.

Nano-scale organisation of cellular adhesions. Cell migration is a key aspect of many normal processes but also of diseases such as cancers. This project will use a novel fluorescence microscope that can see single proteins to identify how cell adhesions are formed, remodelled and disassembled. This knowledge will help to design better drugs against cancers and novel implantable materials.

Summary
An estimated 415 million people world-wide were diagnosed with diabetes in 2015. One of the causal factors in disease is the dysregulation of insulin secretion. We have developed new techniques to study insulin secretion that has led us to propose a new model for secretory control. This proposal sets out experiments to critically test this model. The outcomes could have wide-reaching impact on understanding and for future treatment and prevention of the diabetes.
Novel models to advance our understanding of mammalian development. This project aims to add to the understanding of cellular processes underpinning mammalian development. Protein phosphorylation is a dynamic process regulated by both protein kinases and protein phosphatases.

This project aims to add to the understanding of cellular processes underpinning mammalian development. Protein phosphorylation is a dynamic process regulated by both protein kinases and protein phosphatases. While the role of kinases in cellular functions are well defined, the roles of protein phosphatases are not well understood. Using a range of laboratory models this project aims to discover the function of the phosphatase PP2A, in cell proliferation, survival, differentiation and DNA damage repair. The anticipated outcome is an improved understanding of all stages of mammalian development. This will provide significant benefits in the biotechnology, chemical and pharmaceutical industries.Read moreRead less

Summary
Loss of control of insulin secretion is causal in diabetes and therefore its understanding is a key goal to shed light on the disease. We have recently identified a new domain in the insulin secreting cells, called the apical domain. This proposal will define the role of this apical domain in controlling insulin secretion. The outcomes could provide new insights into how diabetes develops and new targets for therapies.
