The majority of A-to-I RNA editing is not required for mammalian homeostasis

Genome Biology, 2019
Background Adenosine-to-inosine (A-to-I) RNA editing, mediated by ADAR1 and ADAR2, occurs at tens of thousands to millions of sites across mammalian transcriptomes.

Lamarck and immunity: Somatic and germline evolution of antibody genes [PDF]

, 2009
Current work on the mechanism of hypermutation of somatically rearranged antibody variable (V) genes shows that the most likely mechanism involves both direct DNA modification (deamination of cytosines to uracils by AID deaminase) and strand nicking plus

Epigenetic dynamics in gastric cancer precancerous lesions: From molecular mechanisms to precision risk stratification

Clinical and Translational Discovery, Volume 5, Issue 6, December 2025.
Gastric precancerous lesions undergo dynamic epigenetic alterations—including DNA methylation, 5‐hydroxymethylcytosine, non‐coding RNAs, and RNA editing—throughout the Correa's cascade. The integration of these multi‐omics epigenetic signatures facilitates non‐invasive risk stratification, which guides personalised surveillance strategy and targeted ...

Effect of interferons on expression of adenosine deaminase acting on RNA 1 and hepatitis B virus replication in human hepatocellular carcinoma cells in vitro

Di-san junyi daxue xuebao, 2019
Objective To investigate the effect of type Ⅰ interferons (IFN-α and IFN-β) and type Ⅱ interferon (IFN-γ) on the expression of adenosine deaminase acting on RNA 1 (ADAR1, P110 and P150) and hepatitis B virus (HBV) replication in hepatocellular carcinoma (

Solution structure of the N-terminal dsRBD of Drosophila ADAR and interaction studies with RNA [PDF]

, 2012
Adenosine deaminases that act on RNA (ADAR) catalyze adenosine to inosine (A-to-I) editing in double-stranded RNA (dsRNA) substrates. Inosine is read as guanosine by the translation machinery; therefore A-to-I editing events in coding sequences may ...

ADAR1: Beyond Just an RNA Editor

Annual Review of Cell and Developmental Biology
The RNA editing enzyme adenosine deaminase acting on RNA 1 (ADAR1) has recently emerged from relative obscurity to be recognized as a key player in a variety of inflammatory diseases, including cancer. This growing recognition has generated interest in developing ADAR1 inhibitors; however, several fundamental questions about the enzyme need to be ...

Malignant A-to-I RNA editing by ADAR1 drives T cell acute lymphoblastic leukemia relapse via attenuating dsRNA sensing

Cell Reports
Summary: Leukemia-initiating cells (LICs) are regarded as the origin of leukemia relapse and therapeutic resistance. Identifying direct stemness determinants that fuel LIC self-renewal is critical for developing targeted approaches.

Overexpression of Egr1 Transcription Regulator Contributes to Schwann Cell Differentiation Defects in Neural Crest-Specific Adar1 Knockout Mice

Cells
Adenosine deaminase acting on RNA 1 (ADAR1) is the principal enzyme for the adenosine-to-inosine RNA editing that prevents the aberrant activation of cytosolic nucleic acid sensors by endogenous double stranded RNAs and the activation of interferon ...

An ADAR1 dsRBD3-PKR kinase domain interaction on dsRNA inhibits PKR activation

Cell Reports
Summary: Adar null mutant mouse embryos die with aberrant double-stranded RNA (dsRNA)-driven interferon induction, and Adar Mavs double mutants, in which interferon induction is prevented, die soon after birth.

Large-scale analysis of structural, sequence and thermodynamic characteristics of A-to-I RNA editing sites in human Alu repeats [PDF]

, 2010
Background Alu repeats in the human transcriptome undergo massive adenosine to inosine RNA editing. This process is selective, as editing efficiency varies greatly among different adenosines.
