homeostasis/metabolism
• total bilirubin levels were 5-fold higher in mutant mice
• 60% of total bilirubin was conjugated bilirubin, where as the level of conjugated bilirubin in serum of wild-type mice was undetectable
• level of direct bilirubin were 6.7-fold higher in mutant mice urine
|
• 1.5-fold higher in male mutant mice, but no significant changes was observed between female mutant mice and control mice
|
• a slightly decreased alkaline phosphatase level
|
liver/biliary system
• decreased biliary secretion of dibromosulfphthalein administered intravenously
|
• the biliary excretion rate of glutathione was 16-fold lower in mutant mice
• the biliary excretion rate of bilirubin glucuronides was 2-fold lower in mutant mice
|
• a 3-fold increase in glutathione level in mutant liver extracts
