Non-coding RNAs: key regulators of mammalian transcription.
Non-coding RNAs (ncRNAs) are now recognized as active participants in controlling many biological processes. Indeed, these products of transcription can even control the process of transcription itself. In the past several years, ncRNAs have been found to regulate transcription of single genes, as well as entire transcriptional programs, affecting the expression of hundreds to thousands of genes in response to developmental or environmental signals. Compared to more classical protein regulators, the list of ncRNAs that regulate mRNA transcription in mammalian cells is still small; however, the rate at which new ncRNA transcriptional regulators are being discovered is rapid, suggesting that models for how gene expression is controlled will continue to be redefined as this field develops.
