Article Abstract

N6-methyladenosine (mA) RNA methylation has been considered the most prevalent, abundant, and conserved internal transcriptional modification throughout the eukaryotic mRNAs. Typically, mA RNA methylation is catalyzed by the RNA methyltransferases (writers), is removed by its demethylases (erasers), and interacts with mA-binding proteins (readers). Accumulating evidence shows that abnormal changes in the mA levels of these regulators are increasingly associated with human tumorigenesis and drug resistance. However, the molecular mechanisms underlying mA RNA methylation in tumor occurrence and development have not been comprehensively clarified. We reviewed the recent findings on biological regulation of mA RNA methylation and summarized its potential therapeutic strategies in various human cancers.

Innate immune cells can acquire a memory phenotype, termed trained immunity, but the mechanism underlying the regulation of trained immunity remains largely elusive. Here, we demonstrate that inhibition of Aurora kinase A (AurA) dampens trained immunity induced by β-glucan. ATAC-seq and RNA-seq analysis reveal that AurA inhibition restricts chromatin accessibility of genes associated with inflammatory pathways such as JAK-STAT, TNF, and NF-κB pathways.

Innate immunity is crucial in orchestrating the brain immune response, however, glioblastoma multiforme (GBM) has evolved sophisticated mechanisms to evade innate immune surveillance, posing significant challenges for current immunotherapies. Here, a therapeutic strategy is reported that aims at reactivating innate immune responses in GBM via targeted induction of mitochondrial stress, thereby enhancing tumor immunogenicity. Specifically, innate immune-stimulating nanoparticles (INSTNA) are developed, encapsulating positively charged iridium-based complexes (Ir-mito) and small interfering RNA against Methylation-Controlled J protein (si-MCJ) to attenuate mitochondrial respiration.

Introduction: Small nucleolar RNA (snoRNA) mediates RNA modifications, including 2'-O-methylation (Nm) and pseudouridine (Ψ), which has been proven to impact tumor progression. However, the role of snoRNA in the epigenetics of tumors remains poorly understood due to the lack of sufficiently effective experimental methods to identify snoRNA targets. Here, we identified SNORD13H, a C/D box snoRNA, as being downregulated in hepatocellular carcinoma (HCC), and its low expression was associated with HCC development.

RNA modifications, including N6-methyladenosine (m6A), 5-methylcytosine, and pseudouridine, serve as pivotal regulators of gene expression with significant implications for human health and disease. These dynamic modifications influence RNA stability, splicing, translation, and interactions, thereby orchestrating critical biological processes such as embryonic development, immune response, and cellular homeostasis. Dysregulation of RNA modifications is closely associated with a variety of pathologies.
