- RNA 5-methylcytidine (m⁵C) modification plays an essential role in regulating RNA metabolism and functions in cellular processes. Tools achieve temporal and transcript-specific m⁵C editing for functional studies are still limited. Furthermore, methods enabling m⁵C editing, triggered by specific cellular signals, can contribute to the understanding of m⁵C functions under specific physiological conditions but still lacking. Here, we present a temporally and conditionally controlled m⁵C writing platform engineered through integrating abscisic acid (ABA)-mediated chemically induced proximity with split-dCas13b-NSUN2/NSUN6 technology. This system enables the writing of m⁵C by reconstituting the split dCas13b-based m⁵C editing complex at the guide RNA (gRNA)-targeted RNA transcript sites under the control of the inducer ABA. The deposition of m⁵C is inducible, reversible and selective. The deposited m⁵C is biologically active and influence the stability of endogenous mRNA transcripts. Moreover, by incorporating ABA prodrugs, the m⁵C writing can be triggered by signals associated with distinct physiological or disease conditions (e.g., tumor microenvironment and senescence). This conditional m⁵C editing strategy provides a new programmable tool for studying m⁵C biology in context dependent manners and expands the repertoire of RNA modification editing technologies. - Source: PubMed

Dong ChanjuanXu YingWu KellieMu NathanKumar SatendraLiang Fu-Sen - Endometrial cancer (EC) constitutes a leading gynecologic malignancy for which advanced or metastatic disease presents limited therapeutic options. While RNA modifications are acknowledged as key regulatory elements in cancer, the role of 5-methylcytosine (mC) and its modifying enzymes in EC is still largely unstudied. Here, it demonstrates that the mC methyltransferase NSUN6 is significantly upregulated in EC tissues, and its expression correlates with higher tumor grade and unfavorable prognosis. Functional studies employing gain- and loss-of-function models revealed that NSUN6 specifically enhances EC cell migration and invasion both in vitro and in vivo, without altering proliferation or apoptosis. Mechanistically, NSUN6 drives EMT by catalyzing mC modification on Snail mRNA, which in turn stabilizes the transcript of this key EMT transcription factor. AL398 was identified through structure-based virtual screening as a novel small-molecule inhibitor that binds potently to the NSUN6 active site and suppresses its methyltransferase activity. Treatment with AL398 effectively inhibited the NSUN6/mC/Snail axis, reversed the EMT phenotype, and attenuated EC cell migration, invasion, and metastasis in preclinical models. Collectively, it both validates the NSUN6/mC/Snail axis as a critical EC vulnerability and provides a proof-of-concept inhibitor, AL398, laying the groundwork for the development of first-in-class RNA methylation-targeted therapies against metastatic EC. - Source: PubMed

However, the functioning of m5C-methylated mRNAs differs from the non-methylated ones quite dramatically. Of the eight m5C RNA methyltransferases in humans, only two, NSUN2 and NSUN6, were found to be capable of modifying the main portion of cellular mRNAs. A deficiency of NSUN2 and NSUN6 causes global changes in the transcriptome and translatome, and a corruption of the gene in humans is associated with neurodegenerative diseases and intellectual disability. Despite intensive research of m5C mRNA methylation in recent years, many aspects of this phenomenon and its significance remain problematic and far from understood. In this review, we discuss the available information on mRNA methylome biogenesis, methods for its study and analysis, effects of m5C modification on mRNA life, and place it in the general context of cell biology, attempting to draw the biological relevance of m5C mRNA methylation. We highlight the main inconsistencies and difficulties that arise, analyze their possible causes, and propose potential directions for further research that could clarify the controversial issues and provide a link between the NSUN2 deficiency and neurodegenerative diseases. - Source: PubMed

Babaylova Elena SZolotenkova Elizaveta AMalygin Alexey A - Brain arteriovenous malformations (bAVMs) are high-risk vascular lesions prone to intracranial hemorrhage, with unclear upstream regulatory mechanisms. We integrated 5-methylcytosine (mC) RNA methylation sequencing and transcriptomics in ruptured and unruptured bAVMs to identify differentially methylated non-coding RNAs. Functional validation was performed in human tissues, HUVECs, and zebrafish models. mC profiling revealed global methylation remodeling in ruptured bAVMs, with enrichment of EndMT and Wnt/β-catenin pathways. USP2-AS1 emerged as a key lncRNA showing increased methylation and expression, predominantly in endothelial cells. In HUVECs, USP2-AS1 promoted EndMT-like changes and migration, while its knockdown had opposite effects. NSUN6 was identified as the primary methyltransferase mediating mC modification of USP2-AS1. NSUN6-driven methylation enhanced endothelial plasticity in vitro and induced vascular abnormalities and hemorrhage in zebrafish. Mechanistically, USP2-AS1 activated Wnt/β-catenin signaling, which was essential for these effects and reversible by pathway inhibition. These findings identify a NSUN6-USP2-AS1-Wnt/β-catenin axis that drives endothelial dysfunction and bAVM rupture, suggesting potential therapeutic targets for vascular stabilization. - Source: PubMed

Li GangleiLiu MingjianZhang HongfeiLi SichenLiu YingjunPan TonglinShen ShiyuLi ZongzeZhu Wei - Cadmium (Cd) is an environmental toxicant associated with pancreatic dysfunction and disordered glucose metabolism. Although ferroptosis has been implicated in Cd toxicity, whether Cd exposure is accompanied by changes in selected RNA 5-methylcytosine (mC) regulatory proteins in pancreatic β-cell-related systems remains unclear. Here, mouse NIT-1 cells were exposed to CdSO (4 μmol/L), and ferroptosis-related injury was evaluated using ferrostatin-1 (Fer-1) and erastin together with assays of cell viability, LDH release, reactive oxygen species (ROS), malondialdehyde (MDA), intracellular Fe, and ferroptosis-related proteins. Mouse pancreatic tissue was analyzed after chronic CdSO exposure. CdSO reduced NIT-1 cell viability and increased LDH activity, ROS, MDA, and Fe levels. Fer-1 partially improved cell viability and attenuated ROS and MDA, whereas erastin exacerbated Cd-associated injury. Cd exposure increased FTL abundance and decreased SLC7A11 and GPX4 in NIT-1 cells; chronic CdSO exposure in mice was accompanied by altered ferroptosis-related proteins, increased pancreatic Fe, and reduced serum insulin. In addition, Cd exposure was associated with altered abundance of selected m5C regulatory proteins, including decreased NSUN2 and increased TET2 in NIT-1 cells, and altered NSUN2, NSUN6, ALYREF, and TET2 in mouse pancreatic tissue. Overall, this preliminary descriptive study indicates that CdSO exposure is associated with ferroptosis-related redox/iron imbalance in NIT-1 cells and mouse pancreatic tissue, accompanied by altered abundance of selected m5C regulatory proteins. However, because serum and pancreatic Cd burdens, formal replicate-level correlation analyses, global or transcript-specific mC marks, and causal regulatory experiments were not assessed, these findings should be interpreted as associative and descriptive evidence rather than as proof of an internal Cd burden-response relationship or a direct mC-mediated mechanism of ferroptosis regulation. - Source: PubMed
