Background In recent years, a novel animal abdominal aortic aneurysm (AAA) model was established by administering erythropoietin (EPO) to wild-type (WT) mice. However, the influence of EPO on murine fecal microbiota remains uninvestigated. Therefore, this study aims explore potential association between gut changes and AAA development in model. Methods results Adult male C57BL/6 mice were used establish intraperitoneal administration recombinant human at dosage 10,000 IU/kg daily for 28 consecutive days. Hematoxylin eosin (H&E) Elastin Van Gieson (EVG) staining revealed that increased wall thickness diameter, accompanied enhanced degradation elastic lamina. The 16S rRNA—sequencing data deposited Sequence Read Archive (PRJNA1172300). LEfSe analysis Akkermansia, Lawsonibacter, Clostridium, Neglectibacter significantly associated with EPO-induced development, while Lactobacillus, Alistipes, Limosilactobacillus, Eisenbergiella showed significant negative correlations. Analysis using Kyoto Encyclopedia Genes Genomes (KEGG) prediction module differences metabolic pathways two groups, including alanine, aspartate glutamate metabolism; cysteine methionine pyrimidine carbon ABC transporters; oxidative phosphorylation pathways. Conclusions dysbiosis, particularly Alistipes abundance, may contribute formation via inflammation, stress, dysfunction. While advances research, its limitations underscore need validation mechanistic studies. Future work should prioritize multi-omics integration cross-model comparisons unravel complex microbiota-AAA axis.
