Summary
Colon cancer is one of the most common solid tumours in western society. The usual initial treatment is excision of the cancer by an operation done through a cut down the midline of the abdominal wall. Over the past 15 years, minimally invasive technology has changed the approach to many surgical operations. A good example of this is an operation to remove the gall bladder. This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus.

This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus. An image on a video screen of the gall bladder is then used to guide instruments to remove the gall bladder without making a large incision in the abdominal wall. This is called a laparoscopic cholecystectomy. The safety of a laparoscopic assisted approach in the removal of colon cancer is yet to be determined. This study will compare the long term and short term outcomes of people who have colon cancers removed whether by laparotomy ( a cut in the midline of the abdominal wall) or by a laparoscopic assisted approach (telescope).Read moreRead less

Regulation of normal colon biology and activation of genes involved colon cancer The c-myb gene is essential for the normal biology of the blood system and the colon. This gene is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks.

This gene is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. There is a large body of evidence that supports the role of c-myb in the regulation of the blood system. We believe that the rules that govern the production of the huge number of cells needed to have a healthy blood system are similar if not identical to the rules used by the colon. This is because the colon also produces a massive number of cells each with special tasks and a defined life span of a few days. It is this rapid expansion of cell numbers and the programmed short life span of cells that necessitates multiple controls and very tight regulation. Furthermore if this process is hijacked by genetic changes that undermine these controls then there are numerous opportunities to initiate and potentiate malignant change or cancer. This project examines the role of the same genes in two contexts. Firstly when the genes are expressed at normal, highly regulated levels associated with the normal biology of the colon. The second context is when these genes are permitted to be over-expressed and thus drive processes for longer or in inappropriate situations leading to malignant growth.Read moreRead less

Summary
c-myb is essential for the normal biology of the blood system and the colon. It is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. Another group of factors that make up theWnt pathway also contribute to the normal biology of the colon in man and mouse. Defects that lead to too much c-myb and ineffective control of the Wnt pathway appear to work together to increase the risk and severity of colon cancer ....c-myb is essential for the normal biology of the blood system and the colon. It is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. Another group of factors that make up theWnt pathway also contribute to the normal biology of the colon in man and mouse. Defects that lead to too much c-myb and ineffective control of the Wnt pathway appear to work together to increase the risk and severity of colon cancer. This project is designed to specifically test this observation in animals. In addition it examines in fine detail how c-myb levels increase in colon cancer and how it combines with the Wnt pathway to regulate other genes in colon cancer.Read moreRead less

Quantitative Proteomic Analysis Of Faecal Biomarkers For Colon Cancer

Summary
We have identified a number of potential biomarkers present in the stools of patients with colorectal cancer (CRC). We will use quantitative mass spectrometric techniques that we have developed to validate these biomarkers on a large number of faecal samples from patients with CRC and multiple control groups. We believe these studies will lead to a new panel of biomarkers which will improve the detection of early forms of colon cancer, thus reducing death from this disease.

Summary
Colorectal cancer (CRC) causes more cancer deaths in Australia than any other cancer. While early detection improves survival rate, nearly half of all CRC patients succumb to the disease within five years. In general, metastatic CRC is resistant to chemotherapy and radiotherapy and new therapies are required. An increased knowledge of the processes that contribute to the malignant state is likely to suggest new targets for treatment. CRC, like all cancer, is the result of genetic abnormalities ( ....Colorectal cancer (CRC) causes more cancer deaths in Australia than any other cancer. While early detection improves survival rate, nearly half of all CRC patients succumb to the disease within five years. In general, metastatic CRC is resistant to chemotherapy and radiotherapy and new therapies are required. An increased knowledge of the processes that contribute to the malignant state is likely to suggest new targets for treatment. CRC, like all cancer, is the result of genetic abnormalities (mutations) that are acquired over the course of a lifetime. Together the mutated genes produce changes in cell behaviour in processes such as growth, migration, angiogenesis (the ability to attract a blood supply) and cell death. All of these processes are active during normal development of a vertebrate organism, but are generally shutdown in the adult state, except in cancer. In this study we will analyse a group of genes that we have recently shown to be indispensable for normal intestinal development in zebrafish. Zebrafish are small tropical fish that are used frequently for genetic studies. They are very closely related to mammals and it has been shown that the genetic pathways that control the development of this animal are highly conserved in fish and mammals. Importantly, the genetic pathways that lead to cancer in humans are also strikingly similar in zebrafish. Our experiments will use mouse models to discover whether the zebrafish genes we have identified can lead to cancer when they are aberrantly expressed in the intestines of mice. Any genes that are found to contribute to the development of cancer in these models could become potential new targets for cancer therapy.Read moreRead less
