Tsc2tm1Djk/Tsc2+ mice develop renal, liver, lung and extremity tumors

respiratory system

renal/urinary system
• less than 10% incidence

liver/biliary system
• 50% incidence; causes fatal bleeding in 10% of these cases

neoplasm
• reported at 15 months of age
• Background Sensitivity: note that the tumor expression pattern is influenced by genetic background; authors note fewer large renal cystadenomas in outbred Black Swiss background and more angiosarcomas in 129S4/SvJae chimeric mice
• 50% incidence; causes fatal bleeding in 10% of these cases
• less than 10% incidence
• less than 10% incidence

N normal phenotype
behavior/neurological
N
• mice exhibit normal motor skills, exploratory behavior, anxiety and social approach behavior
• following contextual conditioning, mice exhibit reduced freezing compared to wild-type mice
• however, treatment with rapamycin re-establishes normal contextual conditioning
• in a hippocampus-dependent version of the Morris water maze test, spatial learning is impaired compared to in wild-type mice
• however, spatial learning in a hippocampus-independent water maze is normal and treatment with rapamycin re-establishes normal spatial learning
• mice exhibit more across-phase errors compared to in wild-type mice in a hippocampus-dependent win-shift version of the eight-arm radial maze

nervous system
N
• mice exhibit normal basal synaptic transmission, paired-pulse facilitation and early-phase long term potentiation
• mice exhibit lowered late-phase threshold for long term potentiation compared to in wild-type mice
• however, treatment with rapamycin re-establishes normal late-phase long term potentiation
