Funded Activity 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 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.
