WebSep 25, 2007 · Small RNAs (sRNAs) regulate gene expression post-transcriptionally by base pairing with the mRNA. Here we use dynamical simulations to characterize this regulation … WebDiscovered a little over two decades ago, small interfering RNAs (siRNAs) and microRNAs (miRNAs) are noncoding RNAs with important roles in gene regulation. The major difference between siRNAs and miRNAs is that the former are highly specific with only one mRNA target, whereas the latter have multiple targets.

WebControl of gene expression by these small, noncoding RNA molecules was first observed in 1993, when a team of scientists discovered a small, double-stranded RNA (dsRNA) in nematode (... WebMicro-RNA (miRNA) is a class of small noncoding RNAs that regulate gene expression by binding to 3′UTR, 5′UTR, promoter sequences, introns, and coding regions of their target mRNAs. miRNAs are mostly multivalent that one miRNA can bind to several target mRNAs. ERG has been reported as an important target of various miRNAs.
WebIt's a class of small RNA molecules that guide covalent modifcations of ribosomal RNA, transfer RNA, and small nuclear RNAs, primarily through methylation, which is the addition of methyl groups, or pseudouridylation, which is the addition of an isomer of the nucleoside uridine. Another class of non-coding RNAs are the small nuclear RNAs, or ... WebFeb 22, 2024 · Here, we show that Dicer dependent tsRNAs promote gene silencing through a mechanism distinct from PTGS and TGS. tsRNAs can lead to downregulation of target genes by targeting introns via nascent RNA silencing (NRS) in nuclei. Furthermore, we show that Ago2 slicer activity is required for this mechanism.
