Enhancement of RNA Interference Effect in P19 EC Cells by an RNA-dependent RNA Polymerase
Background: RNA interference (RNAi) is a phenomenon uses double-stranded RNA (dsRNA) to specifically inhibit gene expression. The non-specific silencing caused by interferon response to dsRNA in mammalian cells limits the potential of utilizing RNAi to study gene function. Duplexes of 21-nucleotide short interfering dsRNA (siRNA) inhibit gene expression by RNAi. In some organisms, siRNA can als...
متن کاملan introduction to rna interference (rnai)
the discovery of rna interference (rnai) in recent years has revolutionized biological and medical research. rnai is the sequence-specific gene silencing triggered by double-stranded rna (dsrna). until a couple of years ago only biologists working with caenorhabditis elegans and plants could use rnai technology to gain insight into gene function……

متن کاملCrossover interference on nucleolus organizing region-bearing chromosomes in Arabidopsis.
In most eukaryotes, crossovers are not independently distributed along the length of a chromosome. Instead, they appear to avoid close proximity to one another--a phenomenon known as crossover interference. Previously, for three of the five Arabidopsis chromosomes, we measured the strength of interference and suggested a model wherein some crossovers experience interference while others do not....
متن کاملUsing RNA interference to identify genes required for RNA interference.
RNA interference (RNAi) is a phenomenon in which double-stranded RNA (dsRNA) silences endogenous gene expression. By injecting pools of dsRNAs into Caenorhabditis elegans, we identified a dsRNA that acts as a potent suppressor of the RNAi mechanism. We have used coinjection of dsRNAs to identify four additional candidates for genes involved in the RNAi mechanism in C. elegans. Three of the gene...
