mortality/aging
• median survival of 118 day

neoplasm
• increased levels of proliferation and DNA damage are seen in lung tissue affected by lymphoma
• lymphomas are more aggressive and most commonly infiltrate the lungs, liver and spleen with less frequent infiltration of the colon and kidney
• develop aggressive and widespread lymphomas involving the lung, liver, thymus, bone marrow and peripheral blood with a significantly reduced latency compared to mice null for Trp53 alone
• about 86% of mice develop lymphomas
• seldom localized to the thymus
• most commonly infiltrate the lungs, liver and spleen with less frequent infiltration of the colon and kidney
• lymphoma cells often completely deplete the lungs, liver and spleen completely obscuring the normal anatomy of these tissues
• significant invasion of the bone marrow is seen
• develop carcinomas in various organs with a significantly reduced latency compared to mice null for Trp53 alone

hematopoietic system
• in pre-neoplastic splenocytes
• accumulation of aneuploidy in splenocytes is seen as early as 2.5 months of age
• increased proliferation in pre-neoplastic bone marrow cells

cellular
• accumulation of aneuploidy in splenocytes is seen as early as 2.5 months of age
• in pre-neoplastic splenocytes

immune system
• in pre-neoplastic splenocytes
• accumulation of aneuploidy in splenocytes is seen as early as 2.5 months of age
