RNA interference and Register Machines (extended abstract) [PDF]
EPTCS 100, 2012, pp. 107-112, 2012 RNA interference (RNAi) is a mechanism whereby small RNAs (siRNAs) directly control gene expression without assistance from proteins. This mechanism consists of interactions between RNAs and small RNAs both of which may be single or double stranded. The target of the mechanism is mRNA to be degraded or aberrated, while the initiator is double stranded ...

Assessment of RNAi-induced silencing in banana (Musa spp.) [PDF]
, 2015 In plants, RNA- based gene silencing mediated by small RNAs functions at the transcriptional or post-transcriptional level to negatively regulate target genes, repetitive sequences, viral RNAs and/or transposon elements.

Active RNA interference in mitochondria [PDF]
Cell Research, 2020 RNA interference (RNAi) has been thought to be a gene-silencing pathway present in most eukaryotic cells to safeguard the genome against retrotransposition. Small interfering RNAs (siRNAs) have also become a powerful tool for studying gene functions.

Pseudogenes, RNAs and new reproducibility norms
eLife, 2020 The partial success of a study to reproduce experiments that linked pseudogenes and cancer proves that understanding RNA networks is more complicated than expected.

RNA interference is mediated by 21- and 22-nucleotide RNAs.
Genes & Development, 2001 Double-stranded RNA (dsRNA) induces sequence-specific posttranscriptional gene silencing in many organisms by a process known as RNA interference (RNAi). Using a Drosophila in vitro system, we demonstrate that 21- and 22-nt RNA fragments are the sequence-

Quantitative analysis of competition in post-transcriptional regulation reveals a novel signature in target expression variation [PDF]
Biophysical Journal, 104 (4), 951-958 (2013), 2012 When small RNAs are loaded onto Argonaute proteins they can form the RNA-induced silencing complexes (RISCs), which mediate RNA interference. RISC-formation is dependent on a shared pool of Argonaute proteins and RISC loading factors, and is thus susceptible to competition among small RNAs for loading.

New insights into control of arbovirus replication and spread by insect RNA interference pathways [PDF]
, 2012 Arthropod-borne (arbo) viruses are transmitted by vectors, such as mosquitoes, to susceptible vertebrates. Recent research has shown that arbovirus replication and spread in mosquitoes is not passively tolerated but induces host responses to control ...

BMJ, 2004 Over the past decade “RNA interference” has emerged as a natural mechanism for silencing gene expression. This ancient cellular antiviral response can be harnessed to allow specific inhibition of the function of any chosen target genes, including those involved in causing diseases such as cancer, AIDS, and hepatitis. RNA interference is already proving

Modeling and Optimization of Genetic Screens via RNA Interference and FACS [PDF]
Prob. Eng. Inf. Sci. 29 (2015) 131-145, 2014 We study mathematically a method for discovering which gene is related to a cell phenotype of interest. The method is based on RNA interference -- a molecular process for gene deactivation -- and on coupling the phenotype with fluorescence in a FACS machine. A small number of candidate genes are thus isolated, and then tested individually.

Virus-derived DNA drives mosquito vector tolerance to arboviral infection
Nature Communications, 2016 Mosquitoes tolerate long-lasting viral infections, which makes them efficient vectors for human viral diseases. Here, the authors show that the tolerance of Aedesmosquitoes to infection with dengue or chikungunya viruses depends on the production of ...
