Reduced neuronal regeneration after perinatal hypoxic-ischemia in Neil3tm1Bjor/Neil3tm1Bjor mice

nervous system
abnormal neuron differentiation ( J:180177 )
• neurospheres exhibit poor growth and skewed differentiation compared with wild-type neurospheres
abnormal neuronal precursor proliferation ( J:180177 )
• decreased proliferation following induction of hypoxia-ischemia
decreased microglial cell activation ( J:180177 )
• decreased following induction of hypoxia-ischemia
increased cerebral infarct size ( J:180177 )
• 2.6-fold larger following induction of hypoxia-ischemia
decreased neuronal precursor cell number ( J:180177 )
• in the striatum following induction of hypoxia-ischemia

homeostasis/metabolism
abnormal DNA repair ( J:180177 )
• paraquat-treated neurospheres exhibit increased accumulation of strand breaks compared with wild-type cells
• however, brains do not accumulate double-strand breaks
increased cerebral infarct size ( J:180177 )
• 2.6-fold larger following induction of hypoxia-ischemia

immune system
decreased microglial cell activation ( J:180177 )
• decreased following induction of hypoxia-ischemia
