| Research Abstract |
Heterozygous germline mutations of mismatch repair (MMR) genes cause human hereditary non-polyposis colon cancer, and homozygous mutations are manifested by early onset of childhood T- or B-cell leukemia. In order to develop models for both colon cancer and lymphoma, we examined induction protocols with radiation and an inflammatory agent in Mlh1-/- homozygous and Mlh1+/- heterozygous mice. The protocols we established reproducibly induced colon cancer in Mlh1-/- homozygous and Mlh1+/- heterozygous mice, and lymphoma in Mlh1-/- homozygous mice using radiation and/or an inflammatory agent.
