SnoRNA signatures in cartilage ageing and osteoarthritis [PDF]

open access: yesScientific Reports, 2020
Abstract Osteoarthritis presents as a change in the chondrocyte phenotype and an imbalance between anabolic and catabolic processes. Age affects its onset and progression. Small nucleolar RNAs (SnoRNAs) direct chemical modification of RNA substrates to fine-tune spliceosomal and rRNA function, accommodating changing requirements for ...

U8 variants on the brain: a small nucleolar RNA and human disease

open access: yesRNA Biology, 2022
Small nucleolar RNAs (snoRNAs) are non-coding RNAs vital for ribosomal RNA (rRNA) maturation. The U8 snoRNA, encoded by the SNORD118 gene in humans, is an atypical C/D box snoRNA as it promotes rRNA cleavage rather than 2′–O–methylation and is unique to ...

A Human snoRNA with MicroRNA-Like Functions [PDF]

open access: yesMolecular Cell, 2008
Small noncoding RNAs function in concert with Argonaute (Ago) proteins to regulate gene expression at the level of transcription, mRNA stability, or translation. Ago proteins bind small RNAs and form the core of silencing complexes. Here, we report the analysis of small RNAs associated with human Ago1 and Ago2 revealed by immunoprecipitation and deep ...

U3 snoRNA genes are multi-copy and frequently linked to U5 snRNA genes in Euglena gracilis§

open access: yesBMC Genomics, 2009
Background U3 snoRNA is a box C/D small nucleolar RNA (snoRNA) involved in the processing events that liberate 18S rRNA from the ribosomal RNA precursor (pre-rRNA). Although U3 snoRNA is present in all eukaryotic organisms, most investigations of it have

Generation of a mouse model with down-regulated U50 snoRNA (SNORD50) expression and its organ-specific phenotypic modulation. [PDF]

open access: yesPLoS ONE, 2013
Box C/D-type small nucleolar RNAs (snoRNAs) are functional RNAs responsible for mediating 2'-O-ribose methylation of ribosomal RNAs (rRNAs) within the nucleolus.

snoRNAs are Deregulated in Patients with Parkinson’s Disease

open access: yesPamukkale Medical Journal, 2022
Purpose: Small nucleolar RNAs are ranging from 65 to 300 nucleotides in length that mediate post-transcriptional RNA modifications. They don’t have a 5′-Cap and a poly-A tail and are categorized as C/D box snoRNAs, H/ACA box snoRNAs, and small Cajal body-specific RNAs. snoRNAs have essential roles in important biological processes such as transcription,

Matching of Soulmates: Coevolution of snoRNAs and Their Targets [PDF]

open access: yesMolecular Biology and Evolution, 2013
Ribosomal and small nuclear RNAs (snRNAs) comprise numerous modified nucleotides. The modification patterns are retained during evolution, making it even possible to project them from yeast onto human. The stringent conservation of modification sites and the slow evolution of rRNAs and snRNAs contradicts the rapid evolution of small nucleolar RNA ...
