Certain Adenylated Non-Coding RNAs, Including 5′ Leader Sequences of Primary MicroRNA Transcripts, Accumulate in Mouse Cells following Depletion of the RNA Helicase MTR4 [PDF]

open access: yes, 2014
RNA surveillance plays an important role in posttranscriptional regulation. Seminal work in this field has largely focused on yeast as a model system, whereas exploration of RNA surveillance in mammals is only recently begun.

Systematic discovery of structural elements governing stability of mammalian messenger RNAs. [PDF]

open access: yes, 2012
Decoding post-transcriptional regulatory programs in RNA is a critical step towards the larger goal of developing predictive dynamical models of cellular behaviour.

Dynamic regulation of ARGONAUTE4 within multiple nuclear bodies in Arabidopsis thaliana. [PDF]

open access: yesPLoS Genetics, 2008
DNA methylation directed by 24-nucleotide small RNAs involves the small RNA-binding protein ARGONAUTE4 (AGO4), and it was previously shown that AGO4 localizes to nucleolus-adjacent Cajal bodies, sites of snRNP complex maturation. Here we demonstrate that

Transcription boundaries of U1 small nuclear RNA. [PDF]

open access: yesMolecular and Cellular Biology, 1985
Transcription-proximal stages of U1 small nuclear RNA biosynthesis were studied by 32P labeling of nascent chains in isolated HeLa cell nuclei. Labeled RNA was hybridized to nitrocellulose-immobilized, single-stranded M13 DNA clones corresponding to regions within or flanking a human U1 RNA gene. Transcription of U1 RNA was inhibited by greater than 95%

A Conserved CCCH-type Zinc Finger Protein Regulates mRNA Nuclear Adenylation and Export [PDF]

open access: yes, 2011
Coupling of messenger RNA (mRNA) nuclear export with prior processing steps aids in the fidelity and efficiency of mRNA transport to the cytoplasm. In this study, we show that the processes of export and polyadenylation are coupled via the Drosophila ...

Small Nuclear RNA 64 (snoRNA64): A novel Tumor Biomarker for Pancreatic Cancer

open access: yesمجلة بغداد للعلوم, 2023
The pancreatic ductal adenocarcinoma (PDAC), which represents over 90% of pancreatic cancer cases, has the highest proliferative and metastatic rate in comparison to other pancreatic cancer compartments.

Techniques for RNA in vivo imaging in plants [PDF]

open access: yes, 2014
Since the discovery of small RNAs and RNA silencing, RNA biology has taken a centre stage in cell and developmental biology. Small RNAs, but also mRNAs and other types of cellular and viral RNAs are processed at specific subcellular localizations.

Cloning and molecular characterization of Trypanosoma cruzi U2, U4, U5, and U6 small nuclear RNAs

open access: yesMemorias do Instituto Oswaldo Cruz, 2007
Small nuclear RNAs (snRNAs) are important factors in the functioning of eukaryotic cells that form several small complexes with proteins; these ribonucleoprotein particles (U snRNPs) have an essential role in the pre-mRNA processing, particularly in ...

New small nuclear RNA gene-like transcriptional units as sources of regulatory transcripts. [PDF]

open access: yesPLoS Genetics, 2007
By means of a computer search for upstream promoter elements (distal sequence element and proximal sequence element) typical of small nuclear RNA genes, we have identified in the human genome a number of previously unrecognized, putative transcription ...

Spliceosomal snRNA Epitranscriptomics

open access: yesFrontiers in Genetics, 2021
Small nuclear RNAs (snRNAs) are critical components of the spliceosome that catalyze the splicing of pre-mRNA. snRNAs are each complexed with many proteins to form RNA-protein complexes, termed as small nuclear ribonucleoproteins (snRNPs), in the cell ...
