cellular

increased neuron apoptosis ( J:180632 )

• primary neuronal cultures from the neocortex and cerebellum exhibit higher levels of apoptosis than wild-type cultures but not as high as in homozygous cultures

• mutants exhibit a higher number of TUNEL-positive neurons in the medial neocortex and cerebellumthan wild-type mice, although levels are much lower than in homozygotes

abnormal neuron differentiation ( J:180632 )

• marker analysis indicates that mutants exhibit a delay in neuronal differentiation, but to a smaller extent than in homozygotes

oxidative stress ( J:180632 )

• mutants exhibit an increase in oxidative stress in brain sections and primary neural cultures, but less than in homozygotes

nervous system

increased neuron apoptosis ( J:180632 )

abnormal neuron differentiation ( J:180632 )

• marker analysis indicates that mutants exhibit a delay in neuronal differentiation, but to a smaller extent than in homozygotes

abnormal neocortex morphology ( J:180632 )

• brain sections from E19 fetuses exhibit a 15% increase in the number of peroxisomes/area in the cerebellum and medial neocortex
