phenotype observed in females

N normal phenotype
mortality/aging
• male mice rarely survive past 4 to 6 weeks of age

homeostasis/metabolism
• significantly increased levels observed in male mutant mice
• significantly increased levels observed in male mutant mice
• significantly increased levels observed in male mutant mice
• significantly increased levels observed in male mutant mice

liver/biliary system
• a highly compressed parenchyma results from the presence of a large bladder

renal/urinary system
• large bladders leads to distended kidneys and pelvis
• ureters are severely distended due to fluid from enlarged bladders
• mice exhibit a severe distention of the bladder with a thin wall and lacking any significant smooth muscle layer
• male mice show show obvious signs of distension at birth and exhibit a rapid pathologic progression
• female mice have a slower pathological progression and only develop overt distended bladders latter in life
• luminal opening of bladder to urethra is small
• a distended bladder is observable in male mice at E18 lacks a smooth muscle layer
• female mice have a less severe morphology of the bladder at E18 with a moderate distension and a thin muscle layer
• a highly disorganized muscle layer is evident around the bladder at E15 with only patchy areas of differentiating muscle cells evident
• there is a 5- to 10-fold increase in the number of apoptotic cells in the mesenchymal layer at E15 compared to wild-type controls
• male bladders are completely refilled within 1 to 2 hours after percutaneous drainage
