Abstract
The aim of this study was to screen genes related to the development and injury of the mouse optic nerve so as to provide possible target genes for gene-engineering therapy of central nervous system (CNS) injury. Gene expression was profiled by cDNA microarrays in the mouse superior colliculus at 8-time points during the development or following injury of the optic nerve; consequently, 1,095 highly expressed genes (ratio ≥2) were identified. Then, these genes were categorized functionally; there were 561 genes (51.19%) with unidentified functions and 534 genes (48.81%) with identified or partially identified functions. After discounting the overlapping genes, 486 genes with identified or partially identified functions were categorized into 17 functional groups. The 17 functional groups were as follows: I transcription regulation, II signal transduction, III protein synthesis, IV materials transporting, V RNA processing, VI metabolism-related genes, VII cell cycle or apoptosis-related genes, VIII extracellular matrix, IX protein folding and degradation, X cytoskeleton, XI histone metabolism, XII nervous system specific functional genes, XIII tumor related genes, XIV DNA replication and repair, XV axon growth and guidance, XVI immune response, and XVII cell adhesion. These genes may play key roles in the development, injury, and repairment of the optic nerve.
