neoplasm

increased tumor incidence ( J:282928 )

• mice typically have multiple tumor bearing organs

• tumors are present in 10 of 18 mice at 18-26 months of age compared to 5 of 19 wild-type controls

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

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

immune system

enlarged spleen ( J:282928 )

• frequently enlarged due to proliferation of transformed cells

enlarged mesenteric lymph nodes ( J:282928 )

• frequently enlarged due to proliferation of transformed cells

liver/biliary system

increased liver tumor incidence ( J:282928 )

digestive/alimentary system

increased gastrointestinal tumor incidence ( J:282928 )

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

growth/size/body

enlarged spleen ( J:282928 )

• frequently enlarged due to proliferation of transformed cells
