MetabolomicsTranslational repression of viral RNA mediates arbovirus persistence in mosquitoes

Persistent infection of mosquito vectors is essential for the transmission of arboviruses, yet how these viruses produce sufficient progeny without compromising host cell fitness remains unclear. Arbovirus genomes exhibit suboptimal codon usage for both human and mosquito hosts, raising questions...

TranscriptomicsAntiviral RNA interference in mammalian cells
Plants and invertebrates protect themselves from viruses through RNA interference (RNAi), yet it remains unknown whether this defense mechanism exists in mammals. Antiviral RNAi involves the processing of viral long double-stranded (ds) RNA molecules into small interfering RNAs (siRNAs) by the ribon...

TranscriptomicsCooler temperatures destabilize RNA interference and increase susceptibility of disease vector mosquitoes to viral infection
The impact of global climate change on the transmission dynamics of infectious diseases is the subject of extensive debate. The transmission of mosquito-borne viral diseases is particularly complex, with climatic variables directly affecting many parameters associated with the prevalence of disease ...

ProteomicsProxitome profiling of a viral suppressors of RNA silencing identifies the DEAD-box RNA helicase RH20 as a positive regulator of antiviral RNA interference in Nicotiana benthamiana
In the prolonged arms race between viruses and their host plants, viruses usually encode viral suppressors of RNA silencing (VSR) to overcome the hosts' defense mechanism by inhibiting RNAi. Barley stripe mosaic virus (BSMV) is an RNA virus characterized by a positive single-stranded genetic structu...

TranscriptomicsGlobal effects of the CSR-1 RNA interference pathway on transcriptional landscape
Argonaute proteins and their small RNA co-factors short interfering RNAs (siRNAs) are known to inhibit gene expression at the transcriptional and post-transcriptional levels. In Caenorhabditis elegans, the Argonaute CSR-1 binds thousands of endogenous siRNAs (endo-siRNAs) antisense to germline trans...

ProteomicsEvidence for an RNAi-independent role of DICER-LIKE2 in conferring growth inhibition and basal antiviral resistance
Higher plants encode four or five DICER-LIKE (DCL) enzymes responsible for the production of small non-coding RNAs which function in RNA interference (RNAi). Different RNAi pathways in plants effect transposon silencing, antiviral defense and endogenous gene regulation. DCL2 acts genetically redunda...

TranscriptomicsSorting of Drosophila small silencing RNAs partitions microRNA* strands into the RNA interference pathway
In flies, small silencing RNAs are sorted between Argonaute1 (Ago1), the central protein component of the microRNA (miRNA) pathway, and Argonaute2 (Ago2), which mediates RNA interference. Extensive double-stranded characterM-bM-^@M-^Tas is found in small interfering RNAs (siRNAs)M-bM-^@M-^Tdirects d...

ProteomicsExploitation of the RNA interference pathway of the human fungal pathogen Aspergillus fumigatus
RNA-based therapeutics are an emerging class of drugs that are changing the way we treat infectious diseases. The versatility of this class is clearly on display in the rapid design and adaptation of the mRNA vaccines to SARS-CoV-2. Despite the success of these therapeutics against viruses, research...

ProteomicsInterference of RNA molecules with protein aggregation in vitro.
The analysis of RNA-protein interactomes indicates that the amount of structure in RNA molecules correlates with the capacity of binding to proteins in vitro and in vivo. To validate this observation, we used an in vitro network that mimics the composition of phase-separated RNA granules. The interf...

TranscriptomicsDEPS-1 promotes P granule assembly and RNA interference in C. elegans germ cells
P granules are germ-cell-specific cytoplasmic structures containing RNA and protein and required for proper germ cell development in C. elegans. A new P-granule-associated protein, DEPS-1, whose loss disrupts P granule structure and function was analysed in this study. Genome wide analysis of gene...
