Identifying modifiers for plasmacytoma susceptibility [ 2003 - 2005 ]

Research Grant

Researchers: Prof Simon Foote (Principal investigator)

Brief description Many oncogenes and tumour suppressor genes have been identified. Activation or deletion of these genes can have profound effects on the control of cell growth and result in tumours. Many tumour suppressor genes give carriers an elevated risk of disease. However in many cases the incidence of these mutations causing cancer is much lower than would be expected, due to other influencing factors. This project aims to try and understand the reasons behind this in a mouse model of cancer, plasmacytomas. Modifers of tumour incidence are proposed for human disease but very little is known about the identity of the genes involved or in the biological pathways regulating tumour incidence. The search for these genes in humans is difficult. We have begun studies to find modifiers of tumourigenesis using the E -v-abl transgenic model of plasmacytomas. This is the mouse equivalent of multiple myeloma. Studies have shown that some strains of mice have markedly different incidences of tumours. C57BL-6 animals are less susceptible with 20% of animals developing tumour by 12 months of age. In contrast, 90% of transgenic animals on the BALB-c background develop tumour by 12 months of age. There is also a significant sex difference with males being more susceptible than females. There is a similar difference in susceptibility in humans to multiple myeloma.
