Abstract
In situ hybridization has revealed a striking subnuclear distribution of c-myc RNA transcripts. A major fraction of the sense-strand nuclear c-myc transcripts was localized to the nucleoli. myc intron 1-containing RNAs were noticeably absent from nucleoli, accumulating instead in the nucleoplasm. The localization of myc RNA to nucleoli was shown to be common to a number of diverse cell types, including primary Sertoli cells and several cell lines. Furthermore, nucleolar localization was not restricted to c-myc and N-myc and myoD transcripts also displayed this phenomenon. In contrast, gamma-actin or lactate dehydrogenase transcripts did not display nucleolar localization. These observations suggest a new role for the nucleolus in transport and/or turnover of potential mRNAs.
