title: Brain-specific small RNA during development and ageing of mice.
abstract: The ID sequence is a repetitive sequence family of rodent species that is transcribed specifically as small RNA in the brain. The amount of brain-specific small RNA in mice was shown to increase greatly in the first month after birth and then to remain unchanged until senescence. This RNA was suggested to be involved in regulation of brain-specific gene expression during postnatal development.
