ICH5R

ICH5R is a mouse model of spontaneous lymphoma. It was developed by crossing the P53 knockout mouse with the E mu Lck-Bcl2 transgenic mouse. This genetic combination leads to a high incidence of B-cell lymphomas in the animals. The "R" in ICH5R refers to the resistance of these lymphomas to certain chemotherapy drugs, making them a valuable tool for studying drug resistance mechanisms. The model exhibits many similarities to human non-Hodgkin lymphoma, including genetic alterations and cellular characteristics. Researchers use ICH5R mice to investigate the pathogenesis of lymphoma, identify new therapeutic targets, and test novel treatment strategies. The model allows for the study of lymphoma development in a living organism, providing insights that are difficult to obtain through in vitro experiments alone. The spontaneous nature of the tumor development in ICH5R mice also makes them useful for understanding the early stages of cancer initiation and progression.
