RNA interference and Register Machines (extended abstract) [PDF]
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]
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.

Pseudogenes, RNAs and new reproducibility norms
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.
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-

Structural insights into RNA processing by the human RISC-loading complex. [PDF]
Targeted gene silencing by RNA interference (RNAi) requires loading of a short guide RNA (small interfering RNA (siRNA) or microRNA (miRNA)) onto an Argonaute protein to form the functional center of an RNA-induced silencing complex (RISC).

Quantitative analysis of competition in post-transcriptional regulation reveals a novel signature in target expression variation [PDF]
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.

Modeling and Optimization of Genetic Screens via RNA Interference and FACS [PDF]
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
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 ...

Mathematical model of plant-virus interactions mediated by RNA interference [PDF]
Cross-protection, which refers to a process whereby artificially inoculating a plant with a mild strain provides protection against a more aggressive isolate of the virus, is known to be an effective tool of disease control in plants. In this paper we derive and analyse a new mathematical model of the interactions between two competing viruses with ...
