mortality/aging
• Background Sensitivity: 40% of mice die on a CBA/N background
|
reproductive system
• rete testis dilation, luminal swelling, and atrophy of the germinal epithelium of the seminiferous tubules
|
• rete testis is dilated due to a water reabsorption failure
|
• the germinal epithelium is atrophied
|
• slightly increased
|
• decreased sperm viability
|
• contains short and dilated tubules with uneven sperm distribution
• epithelial cells show less endocytosis and few secretion components
basal cells detach from adjacent epithelial cells
• some macrophage-like cells, which have amoebic cell membranes and lysosomal granules, are present on the basal side
• the basement membranes are multilaminated and distorted
• ECM-like material accumulates towards the mesenchymal cell layer
|
• some regions lack sperm
|
• sperm are either immotile or have reduced motility
|
• pregnancy rates are reduced when females are mated to wild-type males
• however, pups that are conceived are sired and nurse normally
|
endocrine/exocrine glands
• rete testis dilation, luminal swelling, and atrophy of the germinal epithelium of the seminiferous tubules
|
• rete testis is dilated due to a water reabsorption failure
|
• the germinal epithelium is atrophied
|
• slightly increased
|
growth/size/body
• all surviving mice have growth retardation
|
cellular
• sperm are either immotile or have reduced motility
