m5C‐Modified tRF3b‐CysGCA‐23 Suppresses Bladder Cancer Malignancy by Repressing H3K18 Lactylation via Stabilizing RBM4

Advanced Science, EarlyView.
In this study, we identified an NSUN6‐dependent m5C‐modified tsRNA, m5C‐tRF3b CysGCA‐23 (mtRC), that is downregulated in BC and inversely correlated with disease progression. Mechanistically, mtRC suppresses BC malignancy by stabilizing RBM4, attenuating glycolysis, and thereby limiting H3K18 lactylation–mediated activation of IL1RAP and VASH2 ...

NSUN2‐mediated m5C RNA methylation dictates retinoblastoma progression through promoting PFAS mRNA stability and expression

Clinical and Translational Medicine, 2023
Background The precise temporal and spatial regulation of N5‐methylcytosine (m5C) RNA modification plays essential roles in RNA metabolism, and is necessary for the maintenance of epigenome homeostasis.

tRNA epitranscriptomics and biased codon are linked to proteome expression in [PDF]

, 2018
Among components of the translational machinery, ribonucleoside modifications on tRNAs are emerging as critical regulators of cell physiology and stress response. Here, we demonstrate highly coordinated behavior of the repertoire of tRNA modifications of

Programmable RNA N6,2´‐O‐Dimethyladenosine Editing

Advanced Science, EarlyView.
ABSTRACT N6,2’‐O‐dimethyladenosine (m6Am) is a prevalent RNA modification located at the first transcribed nucleotide adjacent to the 5′ cap of mRNAs, where it has been implicated in gene regulation. However, the lack of methods for precise, transcript‐specific manipulation of m6Am has limited its functional dissection.

NSUN-Mediated m5C RNA Modification in Stem Cell Regulation

Cells
RNA modifications comprise a core epigenetic dimension of gene regulation; among these, N6-methyladenosine (m6A) and 5-methylcytosine (m5C) have been most intensively investigated. While the functions of m6A in stem cell biology have been well characterized, the contributions of m5C remain comparatively less well defined.

Overview of distinct 5-methylcytosine profiles of messenger RNA in human hepatocellular carcinoma and paired adjacent non-tumor tissues

Journal of Translational Medicine, 2020
Background Post-transcriptional methylation modifications, including 5-methylcytosine (m5C) modification, are closely related to the tumorigenesis of cancers.

mRNA:guanine- 7 cap methyltransferases: identification of novel members of the family, evolutionary analysis, homology modeling, and analysis of sequence-structure-function relationships [PDF]

, 2001
Background The 5'-terminal cap structure plays an important role in many aspects of mRNA metabolism. Capping enzymes encoded by viruses and pathogenic fungi are attractive targets for specific inhibitors.

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

Angewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

5‐Methylcytosine Analysis of miRNAs in Minimal Change Disease

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Minimal change disease (MCD) is a glomerular disorder, which is the most common cause of nephrotic syndrome in children. Additionally, the prevalence of MCD in adults has been increasing in recent years. During protein synthesis, noncoding RNAs can be regulated through a variety of modifications, which helps preserve biological diversity and ...
