Summary
Stomach cancer is a major health problem in the world. It is the second most common cancer and the second leading cause of death from cancer, behind lung cancer. In fact, approximately 10% of all new reported cancer cases world-wide are stomach cancer. The risk of stomach cancer increases with age, with risk rising progressively and peaking at about 60 years of age. Men are affected twice as often as women Like all cancers, stomach cancer results from the progressive acquisition of mutations in ....Stomach cancer is a major health problem in the world. It is the second most common cancer and the second leading cause of death from cancer, behind lung cancer. In fact, approximately 10% of all new reported cancer cases world-wide are stomach cancer. The risk of stomach cancer increases with age, with risk rising progressively and peaking at about 60 years of age. Men are affected twice as often as women Like all cancers, stomach cancer results from the progressive acquisition of mutations in genes that normally ensure a balance between cell growth and cell death. Mutations which predispose individuals to stomach cancer accumulate in the epithelial cells that provide the lining to the stomach. The progression of stomach cancer proceeds through a number of distinct anatomical stages which can be easily recognised by pathologists. Mutations in a number of genes (known as Kirsten-ras, p53) are commonly found in stomach tumours. Moreover, some of the mutations are highly associated with distinct stages of tumour development. As yet, however, we have no real insights into how these mutations cooperate with each other to produce full-blown (malignant) stomach cancer. In our proposal, we are aiming to establish stomach cancer in mice. Our approach will be to use an existing animal model which is predisposed to stomach cancer. We will progressively introduce mutant genes into stomach epithelial cells and study how they cooperate with each other to produce benign, and ultimately, malignant tumours in the stomach of mice. This will help us to understand which mutant genes are required for each stage in tumour development and may provide more rational approaches to stomac cancer screening and treatment.Read moreRead less
Characterisation Of The Molecular Pathogenesis Of Cancer Cachexia Syndrome In Colorectal Cancer.

Summary
Cachexia is a hypermetabolic wasting syndrome involving depletion of both fat and muscle which affects 80% of cancer patients. The exact mechanisms of this syndrome are unknown at the molecular level and this affects our ability to predict, prevent or treat this problem. This study aims to elucidate the molecular mechanisms of cancer cachexia syndrome with a view to implementing nutritional, exercise and pharmacological interventions to prevent its onset.
The Role Of The TGF-b Superfamily Cytokine MIC-1 In Prostate Cancer Pathogenesis

Summary
We have discovered that a protein called MIC-1 is strongly linked to prostate cancer and is made in large amounts by this tumor. There is a lot of circumstantial evidence that it is involved in the prostate cancer but the proof is missing. We propose to breed mice that are both prostate cancer prone and have genetically modified MIC-1 : mice either are unable to make MIC-1 , or make it in large amounts. We will determine how MIC-1 affects prostate cancer development.

Allogeneic bone marrow transplantation (BMT) remains the most effect curative treatment for patients with a number of malignant conditions, especially leukemia. Graft-versus-Host Disease (GVHD) ocurrs when the newly transplanted bone marrow (which includes the immune system) recognises the transplant recipient as foreign and mounts an immune attack against patient tissues.

Graft-versus-Host Disease (GVHD) ocurrs when the newly transplanted bone marrow (which includes the immune system) recognises the transplant recipient as foreign and mounts an immune attack against patient tissues. GVHD is the major complication of BMT and is responsible for the death of up to half of the patients who receive this procedure. These studies will focus on the ability of a newly defined type of white blood called a regulatory dendritic cell to prevent this complication and avoid the requirement for BMT patients to take drugs that suppress their immune system.Read moreRead less
