neoplasm

increased tumor incidence ( J:282928 )

• tumors are most commonly seen in the spleen, mesenteric lymph nodes, liver, and intestines

• tumors are present in 20 of 25 mice at 18-26 months of age compared to 5 of 19 wild-type controls

increased gastrointestinal tumor incidence ( J:282928 )

• tumors in the lower gastrointestinal tract often lead to destruction of the mucosal surface

increased liver tumor incidence ( J:282928 )

increased lymphoma incidence ( J:282928 )

• some mice have histiocyte-associated lymphoma or B cell lymphoma co-occurring with histiocytic sarcoma

increased histiocytic sarcoma incidence ( J:282928 )

• tumor cell morphology is frequently consistent with malignant histiocytes, although in some mice tumors have a plasma cell appearance

hematopoietic system

enlarged spleen ( J:282928 )

• frequently enlarged due to proliferation of transformed cells

abnormal bone marrow cell physiology ( J:282928 )
