mortality/aging
• only 10% of mice treated with 8 Gy of gamma radiation are viable compared with 60% of similarly treated wild-type mice
• only 56% of mice are viable at 465 days compared with 97% of wild-type mice
• some mice severely runted mice die prematurely without signs of tumors

reproductive system
• few spermatogonia are found within the seminiferous epithelium unlike in wild-type mice
• disorganized
• few spermatogonia are found within the seminiferous epithelium unlike in wild-type mice
• in severely affected mice without inflammation
• at 1.5 to 3.5 months of age
• seminifrous tubules few to no mature spermatozoa unlike in wild-type mice
• seminifrous tubules few to no mature spermatozoa unlike in wild-type mice

immune system
• thymocytes exhibit increased radiosensitivity compared with similarly treated wild-type cells
• class switch recombination is impaired compared to in wild-type mice

neoplasm

cellular
• seminifrous tubules few to no mature spermatozoa unlike in wild-type mice
• seminifrous tubules few to no mature spermatozoa unlike in wild-type mice
• few spermatogonia are found within the seminiferous epithelium unlike in wild-type mice
• bone marrow cells exhibit increased sensitivity to gamma irradiation compared with similarly treated wild-type cells
• thymocytes exhibit increased radiosensitivity compared with similarly treated wild-type cells
• mouse embryonic fibroblasts exhibit decreased cell proliferation compared with wild-type cells
• however, proliferation of mouse embryonic fibroblasts is rescued by hypoxic conditions
• following irradiation, B cells exhibit chromosome structural aberrations compared with similarly treated wild-type cells
• chromosome breaks and metaphase aberrations in activated B cells are increased 4.8-fold compared to in similarly treated wild-type cells

growth/size/body

endocrine/exocrine glands

• disorganized
• few spermatogonia are found within the seminiferous epithelium unlike in wild-type mice
• in severely affected mice without inflammation

hematopoietic system
