Pparaem1Tyrb mutation (1 available); any Ppara mutation (44 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• mice bury a higher number of marbles in the marble-burying test, indicating higher anxiety
• however, mice do not show differences in the open field test, novel object recognition, Y-maze test, three-chamber social interaction test, home cage activity test, tail suspension test, forced swim test, administration of MK-801-induced locomotor hyperactivity or sucrose preference test

nervous system
• mice exhibit a decrease in percentage of mature dendritic spines (stubby + mushroom + branched) and an increased percentage immature spines (filipodia + thin)
• dendritic spine density is lower
• however, mice are healthy without any visible abnormalities in growth or morphology and show normal blood biochemical profiles
• mice exhibit reduced prepulse inhibition at prepulse levels of 70, 78, and 82
• however, average startle response is not different from controls
