Summary
Insulin-like growth factors (IGFs) are important proteins that regulate growth. When not regulated properly, diseases such as cancer can occur. A family of IGF binding proteins regulates IGFs. IGFBPs may inhibit IGFs and we have shown that one of them, IGFBP-6, decreases growth of some experimental cancers. As well as regulating IGFs, some IGFBPs alter cell behaviour independently of IGFs, and we found that IGFBP-6 stimulates cell movement in this way. We will now determine how this happens.

Summary
High glucose levels in diabetes react with proteins to form AGEs and it is thought that this reaction may lead to kidney damage, which is one of the complications of diabetes. However, how this damage occurs is not completely understood. Cells need to maintain their shape and position for an organ to stay healthy. We have shown that AGEs affect kidney cells by interacting with and disturbing the function of proteins that maintain cell shape. We now want to study how this occurs.

Summary
Insulin-like growth factor II (IGF-II) is a protein which is involved in normal growth. However, in some circumstances it may also stimulate cancer growth. IGF binding protein-6 (IGFBP-6) binds to IGF-II and stops its activity. One of the major challenges of modern biology is understanding why some proteins bind to other proteins. Proteins fold in various ways and have specific three-dimensional structures. Two proteins which bind strongly to each other have structures which fit each other like ....Insulin-like growth factor II (IGF-II) is a protein which is involved in normal growth. However, in some circumstances it may also stimulate cancer growth. IGF binding protein-6 (IGFBP-6) binds to IGF-II and stops its activity. One of the major challenges of modern biology is understanding why some proteins bind to other proteins. Proteins fold in various ways and have specific three-dimensional structures. Two proteins which bind strongly to each other have structures which fit each other like a 'lock and key'. The aim of this project is to understand how IGFBP-6 binds to IGF-II by looking at its three-dimensional structure. Using this information, it may be possible to develop new treatments which can inhibit IGF-II activity and therefore may be useful in the treatment of some cancers.Read moreRead less
Evaluation Of Functional Protein Molecules In Treating Obesity

Summary
This project aims to reduce excessive food consumption by controlling the satisfaction that people get from eating. This will be achieved through varying protein supplements (whey, leucine and beta-conglycinin) and their combinations. The idea is that people will feel satisfied despite eating less, leading to weight loss and the correction of related metabolic disorders.

Of Mice And Men: Assessing Dietary Proteins Role On Appetite Regulation, Obesity And Cardiovascular Risk

Summary
While the challenge of understanding and managing the global obesity epidemic is well recognised, the role that nutrition plays is more complex than at first glance. Dietary protein may be of central importance in managing weight and small changes in protein consumption may lead to large changes in energy intake and weight. We propose to look at the effects of dietary protein on appetite, its hormonal regulation, and on the risk of developing metabolic diseases such as diabetes.
