Pseudouridine synthase 1-targeted therapy activates antiviral immunity to boost cancer immunotherapy

Cell Reports
Summary: Pseudouridine is the most abundant epitranscriptomic modification, but its cellular functions remain poorly understood. Here, we identify pseudouridine synthase 1 (PUS1) as a key driver of tumor immune evasion. Specifically, we find that PUS1 is

Pseudouridine excretion in patients with psoriasis

Acta Dermato-Venereologica, 1987
The excretion of pseudouridine in the urine of 17 patients with psoriasis was significantly increased. The largest increase was found in patients with psoriatic arthritis. No correlation between the extent of psoriasis and pseudouridine excretion was found.

Novel Variants in PUS7 Associated With Intellectual Disability and Growth Retardation: Expanding the Clinical Spectrum in 13 Patients

Clinical Genetics, EarlyView.
Novel variants in PUS7 associated with intellectual disability and growth retardation: expanding the clinical spectrum in 13 patients. ABSTRACT Pseudouridylation is a frequent post‐transcriptional modification resulting in uridine isomerization in 5‐ribosyluracil, also called pseudouridine. This mechanism leads to RNA stability with an increase in base‐

RluA is the major mRNA pseudouridine synthase in Escherichia coli.

PLoS Genetics
Pseudouridine (Ψ) is an ubiquitous RNA modification, present in the tRNAs and rRNAs of species across all domains of life. Conserved pseudouridine synthases modify the mRNAs of diverse eukaryotes, but the modification has yet to be identified in ...

The WHO Classification of Genetic Tumour Syndromes: Considerations for Genetics

Clinical Genetics, EarlyView.
The WHO Classification of Tumours underpins the diagnosis of neoplastic conditions. The new WHO classification of genetic tumour syndromes (GTS) provides international standards for their diagnosis. This diagram highlights the chromosomal distribution of the genes involved in the GTS covered in this classification.

Multiomics and machine learning-based analysis of pancancer pseudouridine modifications

Discover Oncology
Pseudouridine widely affects the stability and function of RNA. However, our knowledge of pseudouridine properties in tumors is incomplete. We systematically analyzed pseudouridine synthases (PUSs) expression, genomic aberrations, and prognostic features

Stabilization of RNA stacking by pseudouridine [PDF]

Nucleic Acids Research, 1995
The effect of the modified nucleoside pseudouridine (psi) on RNA structure was compared with uridine. The extent of base stacking in model RNA oligonucleotides was measured by 1H NMR, UV, and CD spectroscopy. The UV and CD results indicate that the model single-stranded oligoribonucleotides AAUA and AA psi A form stacked structures in solution and the ...

Enhanced Intracellular Stability and Translation Efficiency of mRNA Drugs by a 2‐arm mRNA Platform

Advanced Science, Volume 13, Issue 37, 3 July 2026.
We constructed a 2‐arm mRNA, characterized by a unique topology formed through the dimerization of two mRNA 3’ tails. The 2‐arm mRNA improves 3’ tail stability and resistance to nuclease degradation, resulting in an intracellular half‐life of up to 65 h. This method substantially enhances the translation capacity of mRNA drugs.
