immune system
N |
• homozygotes show normal total thymocyte numbers and a normal profile of CD4 and CD8 single-positive and double-positive T lymphocytes relative to wild-type controls; TCR V(D)J joining events are normal with no detectable trans-rearrangements
• B-cell proliferation and class switch recombination to IgG1 are normal following treatment with LPS or IL-4
• serum levels of IgG1, IgG2B, and IgE are normal following inoculation with TNP-KLH
• following whole-body irradiation, IR-induced apoptosis in the spleen and thymus is comparable to that in wild-type controls
• ex vivo analysis revealed normal levels of thymocyte apoptosis after exposure to a range of IR doses
|
• homozygotes display a slightly decreased spleen weight relative to wild-type controls
|
• homozygotes display slightly smaller spleens with reduced cellularity
|
cellular
N |
• following ionizing radiation (IR) or UV-C light treatment, mutant primary MEFs exhibit normal DNA damage-signaling relative to wild-type MEFs
• following IR treatment, mutant MEFs show normal G2/M checkpoint arrest and recovery relative to wild-type MEFs
• following IR or UV-C treatment, clonogenic survival curves are identical to those in wild-type MEFs
|
• in response to acute aphidicolin exposure, mutant MEFs show slightly increased levels of chromosomal aberrations relative to wild-type MEFs
|
hematopoietic system
• homozygotes display a slightly decreased spleen weight relative to wild-type controls
|
• homozygotes display slightly smaller spleens with reduced cellularity
|
reproductive system
N |
• contrary to expectation, homozygotes are fertile
|
neoplasm
N |
• contrary to expectation, homozygotes do not exhibit increased tumor predisposition relative to wild-type controls
