RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression, typically by causing the destruction of specific mRNA. The process in which double-stranded RNAs silence cognate genes. Involves posttranscriptional gene inactivation (‘silencing’) both of transgenes or dsRNA.

RNAi-based therapy may become a powerful tool to treat many diseases whose molecular pathogenesis mechanisms have been thoroughly understood. Het mRNA wordt dan op zijn beurt vertaald tot een eiwit translatie. This abstract may be abridged.

However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution.

RNAi, is een biologisch verschijnsel dat voorkomt bij de meeste eukaryoten.

Er ontstaat nu een dubbelstrengs RNA. Delivery of a double stranded RNA to a model organism, Caenorhabditis elegans, triggered silencing of complementary messenger RNA sequences.

Dit wordt herkend door het enzym Dicer en verknipt in kleine fragmenten, “short interfering RNAs” siRNA van ongeveer 25 basenparen lang met een overhang interfedencja 2 basen aan het 3′- einde. Daarnaast gebruiken zowel planten als dieren dit mechanisme om de activiteit van genen inherferencja controleren en voor genregulatie. This discovery opened new perspectives for research involving gene functions due to the possibility of inhibiting the expression of a specific gene through its mRNA degradation in the cytosol.


Al sinds de jaren tachtig van de twintigste eeuw was bekend dat de antisensketen van een mRNA-molecuul deze kan blokkeren en doen afbreken. In two groups led by A. Mello shared the Nobel Prize in Physiology or Medicine for their work on RNA interference in the nematode worm Caenorhabditis elegans, which they published in Si distingue quindi tra meccanismi coinvolgenti molecole a doppio filamento, RNA interference in senso stretto, mediate da molecole come Short interfering RNA e fenomeni coinvolgenti miRNA, a singolo filamento.

About: RNA interference

RNAi is now known as precise, effici en. Fire und Craig C.

RNAi may be used for large-scale screens that systematically shut down each gene in the cell, which can help to identify the components necessary for a particular cellular process or an event such as cell division. The aim of this paper is to present a potential role of RNAi as a therapeutic method for various diseases. No warranty is given about the accuracy of the copy. Remote access to EBSCO’s databases is permitted to patrons interferenjca subscribing institutions accessing from remote locations for personal, non-commercial use.

Indien het mRNA wordt geblokkeerd kan er geen eiwit meer gevormd worden. Electionfrom Named Graph: RNAi is now known as precise, effici en rdfs: RNAi provides a powerful technique for the derivation and analysis of loss-of-function phenotypes in vertebrate cells.

However, users may print, download, or email articles for interferencjw use. Users should refer to the original published version of the material for the full abstract.

This technique may be also applied as a therapeutic strategy, e. Wanneer een gen actief is wordt het DNA waaruit het gen is opgebouwd overgeschreven naar enkelstrengs mRNA, dat werkt als een boodschapper.

Since the discovery of RNAi and its regulatory potentials, it has become evident that RNAi has immense potential in suppression of desired genes. In the early s, during experiments aimed at intensifying the co lour of Petunia hybryda flowers, a new mechanism of regulation of gene expression was discovered; however, its mechanism, i. RNAi speelt onder andere bij organismen een rol bij de afweer tegen virussen. Fire i Craig C.

RNAi is a valuable research tool, both in cell culture and in living organisms, because synthetic dsRNA introduced into cells can selectively and robustly induce suppression of specific genes of interest. It also influences development.

Sie ist ein Spezialfall der Gen-Stilllegung. In some organisms, this process spreads systemically, despite the initially limited molar concentrations of siRNA. Fire et Craig C. Andrew Fire and Craig C.
