Genes expressed during the cerebellar development of the mouse were identified in 3'-directed cDNA libraries prepared from the postnatal day 4, day 12, and week 6 cerebellar tissues. Among about 5500 clones selected randomly from each library, there were approximately 3500 distinct species. A total of 7728 species were identified in the three libraries, 1346 of which were known genes in the GenBank, 3041 EST-matching genes, and 3341 new genes. Relative expression levels at the three postnatal stages were quantitated by adapter-tagged competitive PCR for 130 known genes that appeared six times or more in one of the libraries. Genes for ribosomal proteins and some cytoskeletal and nuclear proteins were abundantly expressed at the early stage, coincidently with extensive proliferation of granule cells as the major cerebellar component. Genes related to brain functions, including those for mitochondrial activities and some ion channel systems, were more active at a later stage when the majority of granule cells were engaged in axon extension and synapse formation or the cerebellum had reached maturity. Compared to these stage-specifically expressed genes, genes for transcriptional regulation, signal transduction, protein modification, and basic cellular functions, in general, were not abundantly expressed at any stage of development.
