Coilin association with Box C/D scaRNA suggests a direct role for the Cajal body marker protein in scaRNP biogenesis

open access: yesBiology Open, 2014
Spliceosomal small nuclear ribonucleoproteins (snRNPs) are enriched in the Cajal body (CB). Guide RNAs, known as small Cajal body-specific RNAs (scaRNAs), direct modification of the small nuclear RNA (snRNA) component of the snRNP.

Identification of Five Putative Yeast RNA Helicase Genes [PDF]

open access: yes, 1990
The RNA helicase gene family encodes a group of eight homologous proteins that share regions of sequence similarity. This group of evolutionarily conserved proteins presumably all utilize ATP (or some other nucleoside triphosphate) as an energy source ...

A small RNA ofMycoplasma capricolumthat resembles eukaryotic U6 small nuclear RNA

open access: yesNucleic Acids Research, 1993
Mycoplasma capricolum, a parasitic prokaryote, contains several small stable RNAs, besides rRNAs and tRNAs. One of them, designated MCS4 RNA (125 nucleotides in length), has been isolated and sequenced. This RNA is abundant in the cell, and is encoded by two genes.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Multi-omics analysis using antibody-based in situ biotinylation technique suggests the mechanism of Cajal body formation

open access: yesCell Reports
Summary: Membrane-less subcellular compartments play important roles in various cellular functions. Although techniques exist to identify components of cellular bodies, a comprehensive method for analyzing both static and dynamic states has not been ...

Use of RNA secondary structure for evolutionary relationships : investigating RNase P and RNase MRP : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, New Zealand [PDF]

open access: yes, 1998
Bioinformatics is applied here to examine whether RNA secondary structure data can reflect distant evolutionary relationships. This is important when there is little confidence in sequence data such as when looking at the evolution of RNase MRP (MRP ...

A snoRNA modulates mRNA 3' end processing and regulates the expression of a subset of mRNAs. [PDF]

open access: yes, 2017
mRNA 3' end processing is an essential step in gene expression. It is well established that canonical eukaryotic pre-mRNA 3' processing is carried out within a macromolecular machinery consisting of dozens of trans-acting proteins. However, it is unknown

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Mpn1, Mutated in Poikiloderma with Neutropenia Protein 1, Is a Conserved 3′-to-5′ RNA Exonuclease Processing U6 Small Nuclear RNA

open access: yesCell Reports, 2012
Clericuzio-type poikiloderma with neutropenia (PN) is a rare genodermatosis associated with mutations in the C16orf57 gene, which codes for the uncharacterized protein hMpn1.
