cardiovascular system

hemorrhage ( J:160616 )

behavior/neurological

behavior/neurological phenotype ( J:160616 )

N • no difference in gross motor skills and no impairment in motor learning

enhanced behavioral response to xenobiotic ( J:160616 )

• chronic administration fluoxetine leads to a significant reduction in the duration of grooming

increased anxiety-related response ( J:160616 )

• mice show a lower percentage of time spent in the center compartment and a lower number of entries into the center compartment in the open-field test

• reduced time spent in open arms in the elevated-plus-maze test

• increase in marble-burying behavior

increased grooming behavior ( J:160616 )

• a significant increase in the duration of grooming events compared to wild-type

• chronic administration fluoxetine leads to a significant reduction in the duration of grooming

nervous system

abnormal striatum morphology ( J:160616 )

• volume of striatum is significantly reduced compared to wild-type mice

abnormal medium spiny neuron morphology ( J:160616 )

• significant decrease in dendritic complexity of striatal neurons

• a decrease in dendritic arbor complexity at distances greater or equal to 50 um from the soma

abnormal synaptic transmission ( J:160616 )
