Summary: RNA editing, induced by ADAR, plays a crucial regulatory role in metazoans, affecting multiple cellular processes and functions. Despite the development of bioinformatics tools for identifying editing sites, the lack of widely accepted standards and challenges in tumor sample analysis still exist. Numerous editing sites have been reported in non-coding regions, impacting the biosynthesis of ncRNAs.

Summary: Adenosine-to-inosine RNA editing is a widespread post-transcriptional modification system catalyzed by ADAR enzymes, which mainly occurs in dsRNA before splicing. This review focuses on the interconnections between RNA editing and splicing in human cancer. Dysregulated RNA splicing in cancer can lead to the release of excess dsRNA into the cytosol, triggering antiviral-like responses and potentially inhibiting tumor growth. Inhibiting ADAR may enhance the effects of spliceosome inhibitors and could be a promising approach in cancer therapies targeting RNA splicing.

Summary: This study identified reduced A-to-I editing of miR-200b-3p at the 5th position in lower airway cells from moderate-to-severe asthmatics, leading to overexpression of SOCS1 and impaired cytokine signaling. ADAR-mediated editing may contribute to features of moderate-to-severe asthma in adulthood.

Summary: RNA editing by ADAR enzymes converts adenosines into inosines, altering protein-coding sequences and diversifying the proteome; recoding is abundant in neural tissues of coleoid cephalopods with over-representation of nonsynonymous edits; shared, strongly recoded sites in coleoids have been selected for proteome diversification, suggesting that an editable A is more beneficial than an uneditable A or a genomically encoded G.

Summary: Adenosine to inosine (A-to-I) RNA editing is a common RNA modification in mammalian transcriptomes. Upregulated RNA editing enzymes, adenosine deaminase acting on RNAs (ADARs), suggest that monitoring RNA editing patterns could be useful as diagnostic biomarkers for diseases. This article provides an overview of epitranscriptomics and focuses on the detection and analysis of A-to-I RNA editing using bioinformatic tools in RNA-seq data sets, while briefly reviewing its involvement in disease progressions. The authors argue for routine detection of RNA editing patterns in RNA-based data sets to accelerate the identification of disease-related RNA editing targets.

Summary: The DEAD-box proteins, including DDX6, are RNA-binding proteins that play a role in post-transcriptional regulation of gene expression. DDX6 has functions in translational repression, miRNA-mediated gene silencing, and RNA decay in the cytoplasm. Its nuclear function was previously unknown until this study discovered its interaction with ADAR1, a protein involved in RNA editing.

Summary: This study developed an editing identification pipeline specifically for RNA viruses and constructed an atlas of A-to-I RNA editing sites in SARS-CoV-2 from diverse samples. The findings showed that A-to-I editing was dynamically regulated, varied between tissue and cell types, and correlated with the intensity of innate immune response. Additionally, editing hotspots were observed, including recoding sites in the spike gene that affect viral infectivity and antigenicity. The study also provided evidence that RNA editing accelerated SARS-CoV-2 evolution in humans during the epidemic.

Summary: This study identified millions of editing events in Xenopus with high accuracy and systematically mapped the editome across developmental stages, adult organs, and species. The highest deamination activity was observed in early embryogenesis and in the ovary. Editing events showed poor conservation across different Xenopus species. The findings suggest that species-specific editing may play a role in the unique physiology or environmental adaptation of each animal.

Summary: RNA editing is a reversible therapeutic approach for correcting pathogenic mutations. This study presents a small molecule-inducible RNA editing strategy by incorporating aptazymes into ADAR-based RNA editing technology. The aptazymes trigger self-cleavage in the presence or absence of small molecules, allowing controlled RNA editing. This strategy improves the safety and potential clinical applications of RNA editing technology.

Summary: Social insects exhibit extensive phenotypic diversities, suggesting a role for epigenetic regulations beyond the genome level. ADAR-mediated RNA editing expands proteomic diversities and facilitates adaptive evolution. In honeybees, editing is most abundant in the heads, with differences in editing behavior between different castes, indicating a role in caste differentiation.

Summary: Inherited retinal diseases (IRDs) are a complex and heterogeneous group of visual impairments caused by pathogenic variants in numerous genes. The understanding of the genotype-phenotype correlations, inheritance patterns, hypomorphic alleles, and modifier genes associated with IRDs is challenging due to their unique characteristics. Advances in next-generation sequencing have facilitated the identification of novel IRD-related genes and variants. The Global Retinal Inherited Disease (GRID) dataset provides valuable information on the frequencies and complexities of pathogenic variants among 194 genes.

Summary: Gabay et al. presented a highly accurate atlas of A-to-I RNA editing in humans, covering editing sites across different tissues and cell subpopulations. Most edited sites are evolutionarily conserved in non-primate mammals, indicating adaptation. Editing by adenosine deaminases alters mRNA encoded information, affecting protein-coding sequences and diversifying the proteome.

Summary: The study aimed to investigate the prevalence of Leishmania in the blood of patients with active or previous cutaneous leishmaniasis (CL). The findings of this pilot study suggest that people with active or recent CL caused by L. major and L. tropica do not harbor parasites in their blood. Hence, their exclusion from blood donation should be revisited.

Summary: Cutaneous squamous cell carcinoma (CSCC) is a skin cancer that evolves from normal epidermis and is characterized by the disruption of cell-cell contacts and acquisition of a mesenchymal motile phenotype. The decreased expression of miR-199a-3p plays a crucial role in this process by targeting RAP2B and inhibiting the epithelial-to-mesenchymal transition (EMT). Inhibitors of RAP2B or FAK may be potential therapeutic agents for CSCC.

Summary: Atopic dermatitis (AD) is associated with reduced adenosine-to-inosine RNA editing, leading to impairment of the innate immune response and dysregulated type 1 interferon-mediated responses. This alteration in editing may play a role in the pathogenesis of AD as well as other autoimmune and inflammatory diseases, while not being observed in conditions like systemic lupus erythematosus and systemic sclerosis with IFN activation.

Summary: Adenosine-to-inosine RNA editing is essential for immune regulation and is associated with various pathological conditions. In this study, the authors characterized RNA editing in the heart and arteries and found increased editing in patients with atherosclerosis, cardiomyopathies, and heart failure. They identified a specific editing site in the IGFBP7 gene that is consistently elevated in these patients. These findings highlight the importance of RNA editing in cardiovascular diseases.

Summary: This study analyzed the RNA sequences of COVID-19 infected individuals and observed a significant increase in global RNA editing activity in COVID-19 patients. The study also identified specific coding sites with higher editing activity and found that the increase in editing activity during the disease was temporary, returning to baseline levels after symptoms disappeared. These epigenetic changes may contribute to the immune system response and affect adverse outcomes in post-viral cases.
