nervous system
• wild-type neurons co-cultured with microglial cells exposed to TFN-alpha exhibit decreased cell death compared to neurons co-cultured with similarly treated wild-type microglial cells
• TNF-alpha fails to activate microglial cells unlike in similarly treated wild-type microglia
• LPS activation of microglial cells is suppressed compared with similarly treated wild-type cells

• LPS activation of microglial cells is suppressed compared with similarly treated wild-type cells

• at 6, 12, and 24 hrs post I/R injury, kidney ATP levels are 80%, 73%, and 77%, respectively, of those in sham-operated controls, unlike in postischemic wild-type kidneys where ATP levels decline to 28%, 26%, and 43%

cellular
• homozygotes are resistant to apoptosis typically induced by monocular deprivation in the dorsal lateral geniculate nucleus (dLGN)
• in wild-type mice, monocular deprivation causes Trp53 accumulation, cell death, and progressive neuronal loss in the dLGN, with an early accumulation of citrulline
• homozygotes exhibit reduced susceptibility to damage induced by neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)
• mutant mouse embryonic fibroblasts (MEFs) are able to efficiently repair DNA damaged by UV and alkylating agents
• however, mutant MEFs exhibit a reduced proliferation rate relative to wild-type MEFs
• in addition, mutant thymocyte progenitors show impaired proliferation and a slow recovery following whole-body gamma-radiation

homeostasis/metabolism
• homozygotes exhibit reduced susceptibility to damage induced by neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)

• homozygotes exhibit reduced susceptibility to damage induced by neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)

integument
• homozygotes are viable, fertile, of normal size, and do not display any gross physical or behavioral abnormalities
• older homozygotes are susceptible to spontaneous development of skin disease: ~30% of older mice develop epidermal hyperplasia

immune system
• neutrophil infiltration was prevented in TNBS treated mutant mice but not in wild-type

homeostasis/metabolism
• induction of colitis resulted in reduced epithelial apoptosis in inflamed colon and faster resolution of colon damage compared to wild-type (J:94172)
• induction of colitis with rinitrobenzenesulfonic acid (TNBS) resulted in mucosal congestion, erosion, and hemorrhagic ulcerations of the distal colon and rectum in both wild-type and mutants, however the damage started to resolve after 72 hours and by 6-7 days, tissues were normal in mutants but damage was maintained in wild-type (J:94497)
• induction of colitis caused only 20% of mutant mice to develop serious diarrhea and to die within 48 hours compared to 100% of wild-type developing diarrhea and 50% dying (J:94497)
• reduced plasma levels of nitrite/nitrate when colitis was induced
