Rob Ramsay has had a long standing research commitment to understanding bowel and breast cancer using mouse models with defined genetic defects. These sophisticated models replicate various stages of cancer development and some have profound effects on normal tissue biology. He also uses molecular tools to investigate how genes are controlled. These approaches are providing direct input into the development of therapeutic agents for cancer treatment.
DOES BCL-G, A BH3-ONLY PROTEIN, PLAY A ROLE IN INFLAMMATION-ASSOCIATED COLON CANCER?

Summary
Deregulation of the function of several members of the Bcl-2 family has been shown to be an aggravating factor in autoimmune diseases and cancer. Bcl-G is a new and poorly characterized member of this family. We have produced essential tools to study the physiological function of Bcl-G, and discovered that it plays a role in inflammatory bowel disease. We now plan to investigate its possible role in inflammation-associated colon cancer.?

Summary
Colon cancer is the second leading cause of cancer related death in Australia. Understanding the genetic causes of this disease are essential to developing new treatment strategies. The goal of this study is to understand the role of the DUSP5 gene in colon cancer. The findings of this study has the potential to further our understanding of how colon cancers arise and for identifying patients likely to respond to specific existing treatments.
Role Of The EHF Transcription Factor In Regulating The Differentiation Status Of Colon Cancers

Summary
New treatment strategies for colon cancer are urgently needed. This application will test a novel approach for treating colon cancer based on the re-induction of differentiation of colon cancer cells, by reactivating a gene called EHF. We expect this to reduce the propensity for colon cancer cells to spread to distant organs and to increase their sensitivity to chemotherpay. This has the potential to significantly benefit the clinical management of patients with this disease.
I am a molecular-cell biologist studying the genetic regulation of intestinal homeostasis in development and disease with the aim of identifying novel molecular targets for the treatment of disease and that can be validated in relevant preclinical mouse models.
This project aims to develop a new therapy for colorectal cancer (CRC). We have already demonstrated that a molecule called PAK1 is the master regulator of several intracellular signalling pathways, and is essential for CRC growth and invasion. We now plan to study whether inhibitors that block PAK1 activity can prevent the growth of human CRC cells in the laboratory or their development into tumours in animals.
Australasian Randomised Clinical Trial Comparing Laparoscopic And Open Surgical Treatment Of Colon Cancer: Follow-up.

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. An image on a video screen ....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. 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

Summary
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. There is a large body of evidence that supports the role of c-myb in the regulation of the blood system.

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
