N normal phenotype
neoplasm
• mice develop mammary carcinomas with 100% penetrance
• primary tumors develop at varying ages, with the first masses seen between 90-120 days of age
• tumors comprise primarily of solid, glandular and acinar forms and often contain cystic areas
• progression to pulmonary metastases is seen in more than 95% of mice more than 130 days of age

immune system
• B cells from mice with tumors show a reduction in proliferation in response to stimulation with ConA and LPS
• splenocytes from mice with tumor loads show reduced proliferative responses in response to mitogens
• enlarged spleen in mice with tumors, with mice with the highest tumor burdens having the largest spleens
• percentage of tumor-infiltrating Treg cells is increased
• percentage of macrophage-like populations and myeloid cells in the spleen increase with increasing tumor load, with a corresponding decrease in the percentage of T cells
• however, percentage of NKT cells in the spleen is similar to controls
• total number of splenocytes increases progressively with increasing tumor burden
• T cells from CD3/CD28-stimulated splenocytes from tumor-bearing mice produce lower levels of IFN-gamma
• T cells from mice with tumors show a reduction in proliferation in response to stimulation with ConA and LPS
• tumor-bearing mice show increased serum levels of pro-inflammatory cytokines MCP-1 and TNF-alpha
• total number of lymph node cells in tumor-draining lymph nodes increases progressively until a total tumor burden between 8 and 12 cm3 is reached, after which a decrease in lymph node cell numbers is seen
• increase in the percentages of B cells within the tumor-draining lymph nodes of mice with extensive tumor loads
• however, percentage of NKT cells in the tumor-draining lymph nodes is similar to controls

homeostasis/metabolism
• tumor-bearing mice show increased serum levels of pro-inflammatory cytokines MCP-1 and TNF-alpha

hematopoietic system
