Chronic inflammatory disease in Hmox1tm1.2Gkl/Hmox1tm1.2Gkl mice

mortality/aging
premature death ( J:148498 )
• mice die within 6 months because of multiorgan failure
postnatal lethality, incomplete penetrance ( J:148498 )
• mice exhibit partial lethality similar to that observed in Hmox1tm1Poss homozygotes

immune system
increased inflammatory response ( J:148498 )
• mice develop progressive chronic and inflammatory disease unlike wild-type mice
liver inflammation ( J:148498 )
• mice exhibit hepatic inflammatory lesions unlike wild-type mice

liver/biliary system
liver inflammation ( J:148498 )
• mice exhibit hepatic inflammatory lesions unlike wild-type mice
