Charting the unknown epitranscriptome

Nature Reviews Molecular Cell Biology, 2017
RNA modifications can alter RNA structure-function relationships and various cellular processes. However, the genomic distribution and biological roles of most RNA modifications remain uncharacterized. Here, we propose using phage display antibody technology and direct sequencing through nanopores to facilitate systematic interrogation of the ...

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, EarlyView.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

RNA editing contributes to epitranscriptome diversity in chronic lymphocytic leukemia [PDF]

, 2021
RNA editing—primarily conversion of adenosine to inosine (A > I)—is a widespread posttranscriptional mechanism, mediated by Adenosine Deaminases acting on RNA (ADAR) enzymes to alter the RNA sequence of primary transcripts.

Enhancer RNAs in transcriptional regulation: recent insights

Frontiers in Cell and Developmental Biology, 2023
Enhancers are a class of cis-regulatory elements in the genome that instruct the spatiotemporal transcriptional program. Last decade has witnessed an exploration of non-coding transcripts pervasively transcribed from active enhancers in diverse contexts,

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.

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

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 ...

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 ...

Microbial metabolites in tumor epigenetic regulation

iMeta, EarlyView.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...
