Hepatocellular alterations in liver of Acox1tm1Jkr/Acox1tm1Jkr mice

cellular
• reduced numbers of round spermatids

neoplasm
• hepatic adenomas and carcinomas developed by 15 months of age, putatively due to sustained activation of Ppara
• hepatic adenomas and carcinomas developed by 15 months of age, putatively due to sustained activation of Ppara

liver/biliary system
• liver weight accounted for ~11% of total body weight compared to 4% in wild-type mice
• severe microvesicular fatty metamorphosis
• hepatic adenomas and carcinomas developed by 15 months of age, putatively due to sustained activation of Ppara
• hepatic adenomas and carcinomas developed by 15 months of age, putatively due to sustained activation of Ppara
• impaired peroxisome assembly, hepatocyte cell death followed by hepatocellular regeneration
• regenerated hepatocytes exhibited massive spontaneous peroxisome proliferation and led to a complete reversal of fatty metamorphosis by 6 to 8 months of age

homeostasis/metabolism
• accumulation of very long chain fatty acids in blood

reproductive system
• reduced numbers of spermatozoa
• reduced numbers of round spermatids

growth/size/body
• mutant mice weighed 40 to 50% less than wild-type littermates during first 5 months of age
• liver weight accounted for ~11% of total body weight compared to 4% in wild-type mice

endocrine/exocrine glands
