New insights into trypanosomatid U5 small nuclear ribonucleoproteins
(Fundacão Oswaldo Cruz, 2011-03-01)
Several protozoan parasites exist in the Trypanosomatidae family, including various agents of human diseases. Multiple lines of evidence suggest that important differences are present between the translational and mRNA ...

Chromosomal Mapping of Repetitive DNA Sequences in Five Species of Astyanax (Characiformes, Characidae) Reveals Independent Location of U1 and U2 snRNA Sites and Association of U1 snRNA and 5S rDNA
(Karger, 2015-01-01)
Astyanax is a genus of Characidae fishes currently composed of 155 valid species. Previous cytogenetic studies revealed high chromosomal diversification among them, and several studies have been performed using traditional ...
Alteration of the microRNA-122 regulatory network in rat models of hepatotoxicity
(Elsevier Science, 2014-01)
MicroRNAs are small RNA molecules that post-transcriptionally regulate gene expression. MicroRNA-122 is the most abundant and specific liver microRNA. Hepatotoxicity involves a significant alteration of liver gene expression. ...
The Intrinsically Disordered Protein CARP9 Bridges HYL1 to AGO1 in the Nucleus to Promote MicroRNA Activity
(American Society of Plant Biologist, 2020-07)
In plants, small RNAs (sRNA) are loaded into ARGONAUTE (AGO) proteins to fulfill their regulatory functions. Micro RNAs (miRNAs), one of the most abundant classes of endogenous sRNAs, are preferentially loaded into ARGONAUTE1 ...
Exomeres and supermeres: monolithic or diverse?
(Wiley Periodicals, 2022)
Extracellular vesicles (EVs), including exosomes and microvesicles, are far from beingthe only RNA-containing extracellular particles (EPs). Recently, new 35-nm-sized EPswere discovered by asymmetric-flow field-flow ...
Non-coding RNA Expression, Function, and Variation during Drosophila Embryogenesis
(Cell Press, 2018-11)
Long non-coding RNAs (lncRNAs) can often function in the regulation of gene expression during development; however, their generality as essential regulators in developmental processes and organismal phenotypes remains ...
