Identification of additional regulatory RNPs that impact rRNA and U6 snRNA methylation

Biology Open, 2018
Ribosomes can be heterogeneous, and the major contributor to ribosome heterogeneity is variation in rRNA modification. There are two major types of rRNA modification, pseudouridylation and ribose methylation.

Interplay of RNA m6A/m1A/m5C/m7G/ψ Regulators Predicting the Prognosis of Pancreatic Cancer

FASEB BioAdvances, Volume 8, Issue 5, May 2026.
In this study, we comprehensively analyze the 64 RNA modification regulators, including 24 m6A regulators, 13 m1A regulators, 12 m5C regulators, 9 m7G regulators, and 12 pseudouridine regulators in pancreatic cancer in TCGA, GTEx, and HPA databases. We investigate their RNA and protein expression, their association with patients' clinical significance,

Functions and mechanisms of spliceosomal small nuclear RNA pseudouridylation [PDF]

WIREs RNA, 2011
AbstractPseudouridines are the most abundant and highly conserved modified nucleotides identified in spliceosomal small nuclear RNAs (snRNAs). Most pseudouridines are also clustered in functionally important regions of spliceosomal snRNAs. Experiments carried out in several independent experimental systems show that the pseudouridines in spliceosomal ...

A Cluster of Three snoRNAs Including Jouvence Required in the Gut Determines Lifespan and Confers Neuroprotection Through Metabolic Parameters

Aging Cell, Volume 25, Issue 4, April 2026.
The disruption of a cluster of three snoRNAs in the epithelium of the gut deregulates the lipid and sterol (including the cholesterol) homeostasis. At the whole‐organism level, this chronic deregulation, all along life, decreases lifespan and leads to neurodegenerative lesions in old flies.

Structural Basis for Translation Termination on a Pseudouridylated Stop Codon [PDF]

Journal of Molecular Biology, 2016
Pseudouridylation of messenger RNA emerges as an abundant modification involved in gene expression regulation. Pseudouridylation of stop codons in eukaryotic and bacterial cells results in stop-codon read through. The structural mechanism of this phenomenon is not known.

Epigenetic mechanisms and therapeutic innovations in chronic pain‐associated neuropsychiatric co‐morbidities

British Journal of Pharmacology, Volume 183, Issue 7, Page 1313-1340, April 2026.
Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...

Mutation of the NOP10 gene as a cause of steroid-resistant nephrotic syndrome coexisting with cataract, hearing loss, and enterocolitis

Pediatria Polska
Nephrotic syndrome comprises a set of symptoms caused by proteinuria exceeding the compensatory capabilities of the body. Based on treatment response, it is classified as either steroid-sensitive or steroid-resistant nephrotic syndrome (SRNS).

Small Nucleolar RNA Snord17 Promotes Self‐Renewal of Intestinal Stem Cells through Yy2 mRNA Export and Tead4 Activation

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Snord17, through interaction with Thoc3, promotes nuclear export and translation of Yy2 mRNA in Snord17+/+ ISCs. The Yy2 protein subsequently binds the Tead4 promoter to promote its transcription, activating Hippo signaling, which is essential for ISC maintenance.

SHQ1 regulation of RNA splicing is required for T-lymphoblastic leukemia cell survival

Nature Communications, 2018
T-acute lymphoblastic leukemia is an aggressive cancer. Here the authors provide insights into the functional role of SHQ1, an H/ACA snoRNP assembly factor involved in snRNA pseudouridylation, in T-lymphoblastic leukemia cell survival through regulating ...

RNA Regulatory Networks: Key Hubs in the Panorama of Cancer and Emerging Therapeutic Targets

MedComm, Volume 7, Issue 3, March 2026.
RNA regulatory networks play a crucial role in the initiation and progression of cancer through various modes of RNA interactions. Notably, circulating RNAs have emerged as potential biomarkers, while targeted interventions in RNA regulatory networks facilitate precise therapeutic strategies. ABSTRACT Cancer is a global health challenge. The initiation
