mortality/aging
• mice do not survive beyond 20 days of age
|
nervous system
• granule neuron progenitors exhibit reduced proliferation and increased apoptosis compared to in wild-type mice
|
• reduced in the cerebellum
|
• cortical astrocytes exhibit mitochondrial defects, decreased mitochondrial DNA, and increased lactic acid compared to in wild-type mice
|
• DNA repair in response to ultraviolet irradiation or methylmethanesulphonate compared with wild-type astrocyte
• however, astrocytes exhibit normal DNA repair in response to ionizing radiation and hydrogen peroxide
|
cellular
• granule neuron progenitors exhibit reduced proliferation and increased apoptosis compared to in wild-type mice
|
• reduced in the cerebellum
|
• brain cells exhibit defective mitochondria complex I activity and reduced oxidative metabolism compared with wild-type cells
|
• DNA repair in response to ultraviolet irradiation or methylmethanesulphonate compared with wild-type astrocyte
• however, astrocytes exhibit normal DNA repair in response to ionizing radiation and hydrogen peroxide
