The intersection of these two analyses yielded core genes. The MCODE module was used to analyze and identify key genes for further study, including gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and immune infiltration analysis. Potential target drugs for the above target genes were obtained from the Comparative Toxicogenomics Database. Finally, external database validation and cell experiment validation were performed.\nResults: A total of 10 core genes (RPS15A, RPL37A, RPL34, RPL32, RPS27, RPL23, RPS7, RPS27A, TPT1) were selected. GO and KEGG pathway analysis showed that they mainly participate in DNA repair, oxidative stress. The drug database showed that aspirin is linked to most genes. Verification of the external database proved that RPL34 was highly expressed in ICP, with statistically significant differences. In vitro cell experiments have confirmed that the expression levels of RPL34 and the activity of mitochondrial complex I were significantly reduced in human trophoblast cells by taurine intervention. Different concentrations of aspirin intervention can rescue apoptosis, restored mitochondrial complex I activity, and upregulated RPL34 expression via modulation of oxidative stress pathways.\nConclusion: This study identified 10 core genes, and the relationship between RPL34 and ICP was found to warrant further investigation. As a drug targeting RPL34, aspirin may represent a potential therapeutic agent for treating ICP.", "claims": [{"id": "claim-method", "statement": "A t-test was used to compare two groups.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:41496984", "locator": "sections[13] \"Statistical analysis\" paragraph 2", "quote": "A t-test was used to compare two groups."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The dataset GSE282182 used in this study are available in PubMed.
