miEAA is a flexible and comprehensive miRNA enrichment analysis tool based on direct and indirect miRNA annotation. It includes 19 miRNA repositories, covering 10 different organisms and 139,399 functional categories. miEAA has added information on the cellular context of miRNAs, isomiRs, and high-confidence miRNAs to improve the accuracy of results. It also improves the representation of aggregated results, including interactive Upset plots. Finally, miEAA demonstrates its functionality in the context of ageing and emphasizes the importance of carefully considering the miRNA input list. miEAA is free to use and publicly available.
MicroRNAs (miRNAs) are small non-coding RNAs that play a critical role in regulating diverse biological processes. Extracting functional insights from a list of miRNAs is challenging, as each miRNA can potentially interact with hundreds of genes. To address this challenge, we developed miEAA, a flexible and comprehensive miRNA enrichment analysis tool based on direct and indirect miRNA annotation. The latest release of miEAA includes a data warehouse of 19 miRNA repositories, covering 10 different organisms and 139 399 functional categories. We have added information on the cellular context of miRNAs, isomiRs, and high-confidence miRNAs to improve the accuracy of the results. We have also improved the representation of aggregated results, including interactive Upset plots to aid users in understanding the interaction among enriched terms or categories. Finally, we demonstrate the functionality of miEAA in the context of ageing and highlight the importance of carefully considering the miRNA input list. MiEAA is free to use and publicly available at .
