EBV-HSA-RegDB: A database of regulatory interactions between Epstein-Barr virus and human miRNAs.
Article in Archives of virology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus associated with various malignancies and autoimmune diseases. MiRNAs play crucial roles in viral-host interactions by regulating gene expression post-transcriptionally. Understanding the regulatory networks between EBV-encoded miRNAs and human miRNAs is essential for elucidating viral pathogenesis and identifying therapeutic targets. We reported the EBV-HSA miRNA Regulatory Database (EBV-HSA-RegDB, https://lbcd.ufpa.br/ebvhsa or https://lbcd.ia.br/ebvhsa ), an integrated bioinformatics resource that combines comparative sequence analysis, regulatory network reconstruction, experimental data integration, and functional gene enrichment analysis. The database incorporates miRNA sequences from miRBase, experimentally validated miRNA-target interactions from miRTarBase, transcriptomic data from cell line models, and miRNA data from ENCORI/StarBase. We implemented multiple sequence-comparison methods, including Hamming, Levenshtein similarity, and the Needleman-Wunsch alignment algorithm, to investigate miRNA seed and global alignments. The tool reconstructs and enables exploration of a comprehensive regulatory network linking experimental data on EBV-encoded miRNAs, human miRNAs, and their target genes. Gene Ontology and pathway analyses using the KEGG and Reactome databases are also available. Network analysis identified key regulatory hubs and revealed convergent targeting patterns in which EBV and human miRNAs regulate the same target genes (IPO7, DICER, TP53, E2F3, SMAD4, SPRY2) and several pairs of EBV-encoded miRNAs and their human counterparts, with high similarity in their target sequences. Functional enrichment analysis uncovered significant associations with biological processes, molecular functions, cellular components, and pathways relevant to viral infection, immune response, and cellular transformation. The EBV-HSA-RegDB provides a user-friendly, interactive platform for exploring virus-host miRNA regulatory networks. This resource facilitates hypothesis generation regarding EBV pathogenesis mechanisms and may aid in elucidating novel gene targets for EBV-associated diseases.
