mortality/aging
• 10.8% of males die during postnatal growth
|
growth/size/body
• reduced growth in some males after birth
|
behavior/neurological
• mice show hyperactive behaviors in home cages such as continuous jumping or fighting with littermates
• mice jump more frequently when kept alone in home cages or novel cages without cage lids
|
• increase in digging behavior in novel cages
• mice bury more marbles than wild-type mice, indicating compulsive digging in a novel environment
• however, mice show a non-significant increase in repetitive grooming
|
• mice show decreased nesting score in the nesting building assay
|
• in the 3-chamber social interaction test, mice explore the novel social partner less frequently than wild-type mice
• mice show reduced social interaction with a stimulus mouse during a free dyadic encounter, with a few mice running away from the novel mouse
• however, mice show normal responses to both social and non-social cues indicting normal olfactory function
|
• in the 3-chamber social interaction test, mice do not show a preference to explore stranger mouse 2 compared with stranger 1, indicating impaired social novelty recognition
|
• P8 pups emit shorter durations of isolation-induced ultrasonic vocalizations
• adult males emit shorter durations of ultrasonic vocalizations when allowed to interact with a novel female mouse
|
• young mice exhibit spontaneous seizures, with several mice showing lethal seizures
|
nervous system
• young mice exhibit spontaneous seizures, with several mice showing lethal seizures
|
• hippocampal neurons show altered membrane properties, with right hippocampus neurons having higher membrane resistance, smaller capacitance and lower after-hyperpolarization than wild-type neurons while the left hippocampal neurons showing no difference in membrane properties but a lower spike frequency
|
• right hippocampal CA1 pyramidal neurons exhibit smaller after-hyperpolarization
|
• pyramidal neurons show a reduced frequency of mEPSCs in the left hippocampus and increased frequency of mEPSCs in the right hippocampus
