N normal phenotype
mortality/aging
• all mice die between 8 and 12 weeks of age, from cachexia and breathing difficulties

growth/size/body
• beginning at 4 weeks, mutants show a general progressive cachexia
• from 4 weeks of age onward, mutants exhibit severe growth retardation

cellular
• cultured embryonic fibroblasts (MEFs) from null mice release cytochrome C more rapidly than wild-type cells after treatment with hydrogen peroxide
• B and T cell numbers are massively decreased by apoptotic cell death
• levels of apoptotic cell death are elevated in thalamus and striatum
• mitochondrial dysfunction upon cytochrome C release occurs more rapidly in mutant MEFs than wild-type
• mitochondria in mutant cells display faster cristae remodeling and cytochrome C mobilization upon treatment with cBID

immune system
• B and T cell numbers are massively decreased by apoptotic cell death
• at 8 weeks, thymus is massively atrophic weighing ~10% or less compared to controls
• lymphocyte numbers are severely decreased, accompanying lymphoid organ atrophy
• DP T cell number is reduced 100-fold in thymus due to apoptosis, compared with wild-type
• B220+ B cells are depleted in spleen at 7 weeks by apoptosis
• B and T cell numbers are massively decreased by apoptotic cell death
• at 8 weeks, spleen is massively atrophic weighing ~10% or less compared to controls

hematopoietic system
• B and T cell numbers are massively decreased by apoptotic cell death
• at 8 weeks, thymus is massively atrophic weighing ~10% or less compared to controls
• lymphocyte numbers are severely decreased, accompanying lymphoid organ atrophy
• DP T cell number is reduced 100-fold in thymus due to apoptosis, compared with wild-type
• B220+ B cells are depleted in spleen at 7 weeks by apoptosis
• B and T cell numbers are massively decreased by apoptotic cell death
• at 8 weeks, spleen is massively atrophic weighing ~10% or less compared to controls

muscle
• diameter of individual muscle fibers is reduced at 8 weeks
• mice lose muscle mass in the erector spinae and abdominal muscles (and diaphragm), beginning at 4 weeks of age, resulting in postural deformity

nervous system
• degenerative changes in the thalamus and striatum are observed
• striatal dysfunction
• levels of apoptotic cell death are elevated in thalamus and striatum

reproductive system
• size of accessory glands is reduced
• reduced size
• uteri of mice remain prepuberal

respiratory system
• between 8 and 12 weeks, mice have difficulty breathing, likely due to loss of muscle mass

skeleton
• mice display severe kyphosis by 8 weeks

endocrine/exocrine glands
• at 8 weeks, thymus is massively atrophic weighing ~10% or less compared to controls
