Summary
This proposal is to investigate the Grb7 protein that occurs at very high levels in some types of cancer cells, including breast cancer cells. It is thought that Grb7 contributes to the progression of cancer by directly affecting the regulation of other genes. We will investigate the way in which this protein interacts with other proteins and RNA that could underlie the cancer growth and spread. A better understanding of the Grb7 protein will help to establish its potential as a novel drug targe ....This proposal is to investigate the Grb7 protein that occurs at very high levels in some types of cancer cells, including breast cancer cells.

Funding Amount
$467,851.00
Summary
The sulfotransferase SULT4A1 is a novel protein found predominantly in neurons but its function is unknown. This project will investigate the mechanisms that the body uses to regulate the levels of this protein and how it may interfere with other enzymes essential for metabolising hormones and neurotransmitters.
Alpha-2-Macroglobulin And The Transport And Uptake Of The Hormone, Hepcidin

Summary
Hepcidin is a peptide hormone that is a major regulator of iron metabolism. It has been suggested that hepcidin is free in the blood. However, we recently identified that hepcidin binds with alpha-2-macroglobulin (a2-M) in the plasma and this increases the efficacy of this peptide. The demonstration that a2-M plays a role in hepcidin biology will lead to a better understanding of hepcidin physiology, the development of methods for its measurement and improved treatment of iron related diseases.
Insulin-like Growth Factor (IGF)-II Binding Specificity Of IGF Binding Protein-6: Structural And Functional Studies.

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
