Abstract: Small noncoding RNAs regulate a variety of cellular processes, including genomic imprinting, chromatin remodeling, replication, transcription, and translation. Here, we report small replication-regulating RNAs (srRNAs) that specifically inhibit DNA replication of the human BK polyomavirus (BKV) in vitro and in vivo. srRNAs from FM3A murine mammary tumor cells were enriched by DNA replication assay-guided fractionation and hybridization to the BKV noncoding control region (NCCR) and synthesized as cDNAs. Selective mutagenesis of the cDNA sequenc...
