WEBAug 3, 2018 · In this review, we provide an update on canonical and non-canonical miRNA biogenesis pathways and various mechanisms underlying miRNA-mediated gene regulations. We also summarize the current knowledge of the dynamics of miRNA action and of the secretion, transfer, and uptake of extracellular miRNAs.
microRNAs in action: biogenesis, function and regulation
WEBJun 28, 2023 · The pre-miRNA is exported to the cytoplasm and cleaved near the terminal loop by the RNase III Dicer, yielding a miRNA duplex that can interact with a member of the Argonaute (Ago) protein...
Distinct AGO1 and AGO2 associated miRNA profiles in human
WEBIn this work we compared the total miRNA content in AGO1 and AGO2 immunoprecipitates obtained from MCF7 adenocarcinoma cells using TaqMan Low Density miRNA Arrays and successfully verified selected miRNAs with qPCR.
Germline AGO2 mutations impair RNA interference and human
WEBNov 16, 2020 · ARGONAUTE-2 and associated miRNAs form the RNA-induced silencing complex (RISC), which targets mRNAs for translational silencing and degradation as part of the RNA interference pathway.
Origins and Mechanisms of miRNAs and siRNAs - PMC - National …
WEBFeb 2, 2009 · Two primary categories of these small RNAs— short interfering RNAs (siRNAs) and microRNAs (miRNAs)—act in both somatic and germline line-ages in a broad range of eukaryotic species to regulate endogenous genes and to defend the genome from invasive nucleic acids.
New insights into the function of mammalian Argonaute2
WEBNov 12, 2020 · MicroRNAs (miRNAs) are a group of short (approximately 22 nucleotides) noncoding RNAs that are used by the Argonaute (Ago) proteins as guides for identifying complementary sites in the messenger RNAs (mRNAs) that are targeted for repression [1].
Detection of MicroRNAs Released from Argonautes - PubMed
WEBThe Argonaute (AGO) family of proteins plays an essential role in the process of microRNA (miRNA)-mediated gene silencing. More specifically, they are the only known proteins to associate directly with miRNAs within the RNA-induced silencing complex (RISC).
AGO-bound mature miRNAs are oligouridylated by TUTs and ... - PubMed
WEBJun 2, 2020 · MicroRNAs (miRNAs) associated with Argonaute proteins (AGOs) regulate gene expression in mammals. miRNA 3' ends are subject to frequent sequence modifications, which have been proposed to affect miRNA stability. However, the underlying mechanism is not well understood.
