METTL5 Enables Immune Evasion of Liver Cancer via Chemokine mRNA Translation Regulation

Advanced Science, EarlyView.
METTL5 reshapes the tumor immune microenvironment through ribosome 18S rRNA m6A modification to regulate the translation of chemokine mRNA. Targeting METTL5‐mediated immunosuppression unleashes anti‐tumor immunity and improves the efficacy of anti‐PD‐1 therapy.

The Basis and Promise of Programmable RNA Editing and Modification

Frontiers in Genetics, 2022
One key advantage of RNA over genomic editing is its temporary effects. Aside from current use of DNA-targeting CRISPR-Cas9, the more recently discovered CRISPR-Cas13 has been explored as a means of editing due to its RNA-targeting capabilities ...

Towards a 'druggable' epitranscriptome: Compounds that target RNA modifications in cancer [PDF]

, 2021
Epitranscriptomics is an exciting emerging area that studies biochemical modifications of RNA. The field is boosted by the technical efforts of the last decade to characterize and quantify RNA modifications which have led to a map of post-transcripcional

Hepatocyte Mettl3 Deficiency Drives Primary Sclerosing Cholangitis and Liver Fibrosis via Cholangiocyte‐Macrophage Crosstalk

Advanced Science, EarlyView.
Schematic illustration demonstrating that hepatic Mettl3 depletion significantly elevates the secretion of Mif and Csf1. This elevation facilitates Trem2+ macrophage infiltration and triggers cholangiocyte remodeling through the Spp1‐Cd44 interaction, resulting in spontaneous PSC development in vivo.

The epitranscriptome of Vero cells infected with SARS-CoV-2 assessed by direct RNA sequencing reveals m6A pattern changes and DRACH motif biases in viral and cellular RNAs

Frontiers in Cellular and Infection Microbiology, 2022
The epitranscriptomics of the SARS-CoV-2 infected cell reveals its response to viral replication. Among various types of RNA nucleotide modifications, the m6A is the most common and is involved in several crucial processes of RNA intracellular location ...

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

Developmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

NAD tagSeq reveals that NAD+-capped RNAs are mostly produced from a large number of protein-coding genes in Arabidopsis. [PDF]

, 2019
The 5' end of a eukaryotic mRNA transcript generally has a 7-methylguanosine (m7G) cap that protects mRNA from degradation and mediates almost all other aspects of gene expression.

Yeast m6 A methylated mRNAs are enriched on translating ribosomes during meiosis, and under rapamycin treatment [PDF]

, 2015
Interest in mRNA methylation has exploded in recent years. The sudden interest in a 40 year old discovery was due in part to the finding of FTO’s (Fat Mass Obesity) N6-methyladenosine (m6 A) deaminase activity, thus suggesting a link between obesity ...

The 5‐Methylcytosine RNA Modification in Hepatitis B Virus‐Negative Hepatocellular Carcinoma: Insights From Long‐Read Nanopore Sequencing

Molecular Carcinogenesis, EarlyView.
ABSTRACT 5‐Methylcytosine (m5C) RNA modification contributes to tumor initiation and progression. However, its transcriptome‐wide distribution patterns and biological implications in hepatitis B virus (HBV)‐negative hepatocellular carcinoma (HCC) remain poorly understood.
