Embryonic lung fibroblasts (HLF) infected with control lentivirus, or lentivirus expressing MRG15 and MRGX small hairpin RNAs from the H1 polIII promoter. The MRG15 shRNA induces an interferon response that is unrelated to silencing of MRG15.

(Submitter supplied) We used a two-component transgene system to study the RNA-dependent DNA methylation (RdDM) and transcriptional gene silencing (TGS) in Arabidopsis. By profiling the small RNA population in  mutants defected in RdDM or RNA polymerase II-transcribed trigger for generating silencing siRNA, we investigated how repetitive loci such as tandem repeats were regulated transcriptionally through the action of RNA polymerase IV.

(Submitter supplied) In plants, RNA polymerase II (Pol II) transcription of inverted DNA repeats produces hairpin RNAs that are processed by several DICER-LIKE enzymes into siRNAs that are 21-24-nt in length. When targeted to transcriptional regulatory regions, the 24-nt size class can induce RNA-directed DNA methylation (RdDM) and transcriptional gene silencing (TGS). In a forward genetic screen to identify mutants defective in RdDM of a target enhancer leading to TGS of a downstream GFP reporter gene in Arabidopsis thaliana, we recovered a structurally mutated silencer locus, named SΔ35S, in which the 35S promoter driving transcription of an inverted repeat of target enhancer sequences had been specifically deleted. more...

(Submitter supplied) In addition to silencing intended target genes, transfected siRNAs regulate numerous unintended transcripts through a mechanism in which the equivalent of a microRNA-like seed region in the siRNA recognizes complementary sequences in transcript 3' UTRs. The ability to limit such off-target effects would substantially facilitate accurate interpretation of RNA interference (RNAi) experiments and thus greatly enhance their value. more...
