Murari E, Meadows D, Cuda N, Mangone M. A comprehensive analysis of 3'UTRs in Caenorhabditis elegans. Nucleic Acids Res 2024; 52:7523-7538. [PMID: 38917330 PMCID: PMC11260456 DOI: 10.1093/nar/gkae543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 04/29/2024] [Accepted: 06/11/2024] [Indexed: 06/27/2024] Open
Abstract
3'Untranslated regions (3'UTRs) are essential portions of genes containing elements necessary for pre-mRNA 3'end processing and are involved in post-transcriptional gene regulation. Despite their importance, they remain poorly characterized in eukaryotes. Here, we have used a multi-pronged approach to extract and curate 3'UTR data from 11533 publicly available datasets, corresponding to the entire collection of Caenorhabditis elegans transcriptomes stored in the NCBI repository from 2009 to 2023. We have also performed high throughput cloning pipelines to identify and validate rare 3'UTR isoforms and incorporated and manually curated 3'UTR isoforms from previously published datasets. This updated C. elegans 3'UTRome (v3) is the most comprehensive resource in any metazoan to date, covering 97.4% of the 20362 experimentally validated protein-coding genes with refined and updated 3'UTR boundaries for 23489 3'UTR isoforms. We also used this novel dataset to identify and characterize sequence elements involved in pre-mRNA 3'end processing and update miRNA target predictions. This resource provides important insights into the 3'UTR formation, function, and regulation in eukaryotes.

A lineage-resolved cartography of microRNA promoter activity in C. elegans empowers multidimensional developmental analysis. Nat Commun 2024; 15:2783. [PMID: 38555276 PMCID: PMC10981687 DOI: 10.1038/s41467-024-47055-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 03/13/2024] [Indexed: 04/02/2024] Open
Abstract
Elucidating the expression of microRNAs in developing single cells is critical for functional discovery. Here, we construct scCAMERA (single-cell cartography of microRNA expression based on reporter assay), utilizing promoter-driven fluorescent reporters in conjunction with imaging and lineage tracing. The cartography delineates the transcriptional activity of 54 conserved microRNAs in lineage-resolved single cells throughout C. elegans embryogenesis. The combinatorial expression of microRNAs partitions cells into fine clusters reflecting their function and anatomy. Notably, the expression of individual microRNAs exhibits high cell specificity and divergence among family members. Guided by cellular expression patterns, we identify developmental functions of specific microRNAs, including miR-1 in pharynx development and physiology, miR-232 in excretory canal morphogenesis by repressing NHR-25/NR5A, and a functional synergy between miR-232 and miR-234 in canal development, demonstrating the broad utility of scCAMERA. Furthermore, integrative analysis reveals that tissue-specific fate determinants activate microRNAs to repress protein production from leaky transcripts associated with alternative, especially neuronal, fates, thereby enhancing the fidelity of developmental fate differentiation. Collectively, our study offers rich opportunities for multidimensional expression-informed analysis of microRNA biology in metazoans.

Abstract
MicroRNAs (miRNAs) were first discovered in C. elegans as essential post-transcriptional regulators of gene expression. Since their initial discovery, miRNAs have been implicated in numerous areas of physiology and disease in all animals examined. In recent years, the C. elegans model continues to contribute important advances to all areas of miRNA research. Technological advances in tissue-specific miRNA profiling and genome editing have driven breakthroughs in understanding biological functions of miRNAs, mechanism of miRNA action, and regulation of miRNAs. In this review, we highlight these new C. elegans findings from the past five to seven years.

[PMID: 38302463 PMCID: PMC10834975 DOI: 10.1038/s41467-024-45249-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 01/18/2024] [Indexed: 02/03/2024] Open
Abstract
Ageing exhibits common and distinct features in various tissues, making it critical to decipher the tissue-specific ageing mechanisms. MiRNAs are essential regulators in ageing and are recently highlighted as a class of intercellular messengers. However, little is known about the tissue-specific transcriptomic changes of miRNAs during ageing. C. elegans is a well-established model organism in ageing research. Here, we profile the age-dependent miRNAomic changes in five isolated worm tissues. Besides the diverse ageing-regulated miRNA expression across tissues, we discover numerous miRNAs in the tissues without their transcription. We further profile miRNAs in the extracellular vesicles and find that worm miRNAs undergo inter-tissue trafficking via these vesicles in an age-dependent manner. Using these datasets, we uncover the interaction between body wall muscle-derived mir-1 and DAF-16/FOXO in the intestine, suggesting mir-1 as a messenger in inter-tissue signalling. Taken together, we systematically investigate worm miRNAs in the somatic tissues and extracellular vesicles during ageing, providing a valuable resource to study tissue-autonomous and nonautonomous functions of miRNAs in ageing.
