TLDR
It is shown that Argonaute-2 (Ago2) and RNAi factors Dicer, TRBP and TRNC6A/GW182 are in the human nucleus and associate together in multi-protein complexes, demonstrating that RNAi can function in thehuman nucleus and suggesting that regulation of RNAi via small RNA loading of Ago2 differs between the cytoplasm and the nucleus.About:

Overview of MicroRNA Biogenesis, Mechanisms of Actions, and Circulation.
TL;DR: An update on canonical and non-canonical miRNA biogenesis pathways and various mechanisms underlying miRNA-mediated gene regulations and the current knowledge of the dynamics of miRNA action and of the secretion, transfer, and uptake of extracellular miRNAs is provided.

TL;DR: It is shown here that most exosomes derived from standard preparations do not harbor many copies of miRNA molecules, and are, therefore, individually unlikely to be functional as vehicles for miRNA-based communication.
Journal ArticleDOI
Advances in oligonucleotide drug delivery
TL;DR: An overview of oligonucleotide-based drug platforms is provided, focusing on key approaches — including chemical modification, bioconjugation and the use of nanocarriers — which aim to address the delivery challenge.
Journal ArticleDOI
MicroRNA in Control of Gene Expression: An Overview of Nuclear Functions.
TL;DR: The finding that small non-coding RNAs (ncRNAs) are able to control gene expression in a sequence specific manner has had a massive impact on biology and it is becoming evident that miRNAs also have specific nuclear functions.

MicroRNAs: Target Recognition and Regulatory Functions
TL;DR: The current understanding of miRNA target recognition in animals is outlined and the widespread impact of miRNAs on both the expression and evolution of protein-coding genes is discussed.

Duplexes of 21-nucleotide RNAs mediate RNA interference in cultured mammalian cells
TL;DR: 21-nucleotide siRNA duplexes provide a new tool for studying gene function in mammalian cells and may eventually be used as gene-specific therapeutics.
Journal ArticleDOI
An RNA-directed nuclease mediates post-transcriptional gene silencing in Drosophila cells
TL;DR: It is shown that ‘loss-of-function’ phenotypes can be created in cultured Drosophila cells by transfection with specific double-stranded RNAs, which coincides with a marked reduction in the level of cognate cellular messenger RNAs.
Journal ArticleDOI
RNAi: Double-Stranded RNA Directs the ATP-Dependent Cleavage of mRNA at 21 to 23 Nucleotide Intervals
TL;DR: It is found that RNAi is ATP dependent yet uncoupled from mRNA translation, suggesting that the 21-23 nucleotide fragments from the dsRNA are guiding mRNA cleavage.

TL;DR: The evidence supports a model in which Argonaute contributes “Slicer” activity to RISC, providing the catalytic engine for RNAi.
