From transcription to translation: new insights in the structure and function of Argonaute protein
Argonaute proteins play a central role in gene silencing pathways mediated by small RNA molecules. The ancestral function of small RNA-dependent silencing is related to genome protection against parasitic nucleic acids, such as transposons and viruses ...

Aging in women is accompanied by a dramatic change in circulating sex steroid hormones. Specifically, the primary circulating estrogen, 17β-estradiol (E2), is nearly undetectable in post-menopausal women.

The biogenesis pathway of tRNA-derived piRNAs in Bombyx germ cells. [PDF]
Transfer RNAs (tRNAs) function in translational machinery and further serves as a source of short non-coding RNAs (ncRNAs). tRNA-derived ncRNAs show differential expression profiles and play roles in many biological processes beyond translation ...

Argonaute proteins at a glance [PDF]
Although a large portion of the human genome is actively transcribed into RNA, less than 2% encodes proteins. Most transcripts are non-coding RNAs (ncRNAs), which have various cellular functions.

Mechanistic Insights into the Protection Effect of Argonaute–RNA Complex on the HCV Genome
While host miRNA usually plays an antiviral role, the relentless tides of viral evolution have carved out a mechanism to recruit host miRNA as a viral protector.

Small RNAs and extracellular vesicles in filarial nematodes: from nematode development to diagnostics [PDF]
Parasitic nematodes have evolved sophisticated mechanisms to communicate with their hosts in order to survive and successfully establish an infection. The transfer of RNA within extracellular vesicles (EVs) has recently been described as a mechanism that

Antagonistic and cooperative AGO2-PUM interactions in regulating mRNAs. [PDF]
Approximately 1500 RNA-binding proteins (RBPs) profoundly impact mammalian cellular function by controlling distinct sets of transcripts, often using sequence-specific binding to 3' untranslated regions (UTRs) to regulate mRNA stability and translation ...

The evolution of animal Argonautes: evidence for the absence of antiviral AGO Argonautes in vertebrates [PDF]
AbstractIn addition to mediating regulation of endogenous gene expression, RNA interference (RNAi) in plants and invertebrates plays a crucial role in defense against viruses via virus-specific siRNAs. Different studies have demonstrated that the functional diversity of RNAi in animals is linked to the diversification of the Argonaute superfamily ...

MicroRNA-mediated gene silencing: are we close to a unifying model?
MicroRNAs (miRNAs) comprise a group of small non-coding RNA –21 nucleotides in length. They act as post-transcriptional regulators of gene expression by forming base pairing interactions with target messenger RNA (mRNA).

RNA Interference by Single- and Double-stranded siRNA With a DNA Extension Containing a 3′ Nuclease-resistant Mini-hairpin Structure [PDF]
Selective gene silencing by RNA interference (RNAi) involves double-stranded small interfering RNA (ds siRNA) composed of single-stranded (ss) guide and passenger RNAs.
