|
mortality/aging
|
• all homozygotes die from polycystic kidney disease between 2 and 4 weeks of age
|
growth/size/body
|
• all homozygotes die from polycystic kidney disease between 2 and 4 weeks of age
|
|
• all homozygotes become runted
|
immune system
|
• survival of mature resting T and B cells in the absence of cytokines is impaired compared to wild-type cells and similar to mice homozygous for Bcl2tm1Dlo alone
|
renal/urinary system
|
• all homozygotes die from polycystic kidney disease between 2 and 4 weeks of age
|
hematopoietic system
|
• survival of mature resting T and B cells in the absence of cytokines is impaired compared to wild-type cells and similar to mice homozygous for Bcl2tm1Dlo alone
|
growth/size/body
|
• seen in about 50% of mice
|
|
• increase in size is similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
reproductive system
|
• variable abnormalities are seen including vacuolation, multi-nucleate syncytia, accumulation of spermatocytes, and apparent reduction in tubular cellularity, diameter, and lumen size
• the spermatogonia layer is thicker than in wild-type being up to 3 cell layers thick
|
|
• testes weight is reduced at P21 and in adults testes weigh about 60% that of wild-type; however serum concentrations of inhibin and follicle stimulating hormone are normal
|
|
• at P15 the number of germ cells in the testis is increased and these are mostly c-Kit+ early germ cells, but in adult males the number of germ cells is decreased by up to 10-fold compared to wild-type
• in adult males the proportion of early germ cells is increased up to 10-fold compared to controls; however the absolute number is similar to controls
|
|
• arrest is later than in Baxtm1Sjk homozygotes as some round spermatids are present but no elongating spermatids are seen
|
|
• males but not females are sterile
|
immune system
|
• increase in size is similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• in the bone marrow the pro/pre-B and immature B cell populations are reduced and the population of mature b cells is increased similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• abnormalities in T cell development in the thymus (decrease in pre-T cells and increase in pro- and mature T cells) are identical to those in mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• increase in mature B cells in the spleen and bone marrow similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• increase in mature T cells in the spleen similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• similar to mice homozygous for Bcl2l11tm1.1Ast alone
|
|
• survival of mature T cells is increased following cytokine withdrawal or treatment with ionomycin similar to responses in mice homozygous for Bcl2l11tm1.1Ast alone
|

endocrine/exocrine glands
|
• variable abnormalities are seen including vacuolation, multi-nucleate syncytia, accumulation of spermatocytes, and apparent reduction in tubular cellularity, diameter, and lumen size
