tg2

• Allelic Composition: Tg(Alb1HBV)44Bri/0
• Genetic Background: C57BL/6J-Tg(Alb1HBV)44Bri/J

neoplasm

increased incidence of tumors by chemical induction ( J:223921 )

• mice injected with the hepatotoxin AFB1 develop nodules at 6 months after treatment; more nodules are seen in mice treated with AFB1 than in untreated mice and most nodules are large

• abundance and size of liver lesions in adults exposed to AFB1 increase over time after treatment and AFB1 treatment accelerates the liver lesions in older mice

• male neonates exposed to AFB1 show a tendency to develop lesions earlier than females, however, by 15 months, females have an about equal frequency of liver lesions as males

• mice injected with AFB1 at day 7 develop regenerative foci, adenoma, and carcinoma as do mice injected with AFB1 in adulthood but much more frequently

increased liver tumor incidence ( J:223921 )

• mice develop nodules in the liver at 9 months of age; nodules are mostly small although some large ones develop

increased hepatocellular carcinoma incidence ( J:223921 )

• end-stage liver tumors are molecularly similar and resemble hepatocellular carcinoma

increased liver adenoma incidence ( J:223921 )

• mice develop only regenerative foci or adenomas at 15 months of age

homeostasis/metabolism

increased incidence of tumors by chemical induction ( J:223921 )

• mice injected with the hepatotoxin AFB1 develop nodules at 6 months after treatment; more nodules are seen in mice treated with AFB1 than in untreated mice and most nodules are large

• abundance and size of liver lesions in adults exposed to AFB1 increase over time after treatment and AFB1 treatment accelerates the liver lesions in older mice

• male neonates exposed to AFB1 show a tendency to develop lesions earlier than females, however, by 15 months, females have an about equal frequency of liver lesions as males

• mice injected with AFB1 at day 7 develop regenerative foci, adenoma, and carcinoma as do mice injected with AFB1 in adulthood but much more frequently

immune system

liver inflammation ( J:223921 )

• mice develop overt liver lesions (hepatitis) beginning from 9-12 months of age

• mice injected with the hepatotoxin AFB1 develop a large number of liver lesions that are obvious from 9 months after treatment

• mice injected with AFB1 at adulthood show an increase in liver lesions compared with untreated mice

• males are more susceptible to liver lesions much earlier than females when adults are injected with AFB1 at 6 months, although by 5 months, similar incidence rates are seen for both genders

tg3

• Allelic Composition: Tg(Alb1HBV)44Bri/0
• Genetic Background: involves: C57BL/6J * SJL/J

neoplasm

increased liver tumor incidence ( J:86165 )

• 9-12 months after the onset of hepatocellular injury, mutants develop liver tumors, with all mice developing hepatocellular neoplasms by 18-21 months of age

• multiple tumors of various sizes are present in the same liver and tumors are highly vascularized

• Background Sensitivity: liver tumors develop more rapidly in mice derived from transgenic by nontransgenic (C57BL/6J x SJL/J) matings than in mice derived by repeated backcrossing against C57BL/6J mice

• in mutants backcrossed against C57BL/6J, males develop liver tumors more rapidly than females

• younger males tend to harbor adenomas, while carcinomas are more common in older males

increased hepatocellular carcinoma incidence ( J:86165 )

increased liver adenoma incidence ( J:86165 )

• hepatocellular adenomas

liver/biliary system

abnormal liver morphology ( J:86165 )

• mutants develop hepatocellular injury at around 2-3 months of age, followed by hyperplasia and neoplasia

increased liver tumor incidence ( J:86165 )

• 9-12 months after the onset of hepatocellular injury, mutants develop liver tumors, with all mice developing hepatocellular neoplasms by 18-21 months of age
