Brain damage in Npas4tm1Ooe/Npas4tm1Ooe mice

mortality/aging
• at 15 weeks, 3 of 8 mice treated with 28 mg/kg kainate die unlike similarly treated wild-type mice
• at 16 months of age, 20% to 30% of mice survive whereas almost all wild-type mice are alive

nervous system
• at 15 weeks, kainate-treated mice exhibit myoclonic epilepsy and serious brain damage unlike wild-type mice that exhibit mild neuronal damage
• at 15 weeks, kainate-treated mice exhibit myoclonic epilepsy and serious brain damage unlike wild-type mice that exhibit mild neuronal damage
• mice exhibit severe neuronal cell damage with heavy glial cell activation unlike in wild-type mice
• mice exhibit severe neuronal cell damage with heavy glial cell activation unlike in wild-type mice
• at 30 weeks

behavior/neurological
• at 3 months of age, mice exhibit crouching, bending back and abnormal jumping that often result in self-injury unlike wild-type mice
• at 15 weeks, kainate-treated mice exhibit myoclonic epilepsy and serious brain damage unlike wild-type mice that exhibit mild neuronal damage

homeostasis/metabolism
• at 15 weeks, kainate-treated mice exhibit myoclonic epilepsy and serious brain damage unlike wild-type mice that exhibit mild neuronal damage
• at 15 weeks, 3 of 8 mice treated with 28 mg/kg kainate die unlike similarly treated wild-type mice

muscle
• at 15 weeks, kainate-treated mice exhibit myoclonic epilepsy and serious brain damage unlike wild-type mice that exhibit mild neuronal damage

cellular
• at 15 weeks, kainate-treated mice exhibit myoclonic epilepsy and serious brain damage unlike wild-type mice that exhibit mild neuronal damage
