Herein, we identified and verified latent lipid-related genes involved in AMI by bioinformatic analysis. Lipid-related differentially expressed genes (DEGs) involved in AMI were identified using the GSE66360 dataset from the Gene Expression Omnibus (GEO) database and R software packages. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted to analyze lipid-related DEGs. Lipid-related genes were identified by two machine learning techniques: least absolute shrinkage and selection operator (LASSO) regression and support vector machine recursive feature elimination (SVM-RFE). The receiver operating characteristic (ROC) curves were used to descript diagnostic accuracy. Furthermore, blood samples were collected from AMI patients and healthy individuals, and real-time quantitative polymerase chain reaction (RT-qPCR) was used to determine the RNA levels of four lipid-related DEGs. Fifty lipid-related DEGs were identified, 28 upregulated and 22 downregulated. Several enrichment terms related to lipid metabolism were found by GO and KEGG enrichment analyses. After LASSO and SVM-RFE screening, four genes (ACSL1, CH25H, GPCPD1, and PLA2G12A) were identified as potential diagnostic biomarkers for AMI. Moreover, the RT-qPCR analysis indicated that the expression levels of four DEGs in AMI patients and healthy individuals were consistent with bioinformatics analysis results. The validation of clinical samples suggested that 4 lipid-related DEGs are expected to be diagnostic markers for AMI and provide new targets for lipid therapy of AMI.", "claims": [{"id": "claim-method", "statement": "The “limma” R package was used to identify lipid-related DEGs between AMI patients and normal participants.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36863716", "locator": "sections[13] \"Identification of lipid-related DEGs\" paragraph 2", "quote": "The “limma” R package was used to identify lipid-related DEGs between AMI patients and normal participants."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The GSE66360 dataset including a total of 99 circulating endothelial cell samples that collected from 49 AMI and 50 control subjects, and this dataset was based on the GPL570 platform (Affymetrix Human Genome U133 Plus 2.0 Array).", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36863716", "locator": "sections[12] \"Lipid-related gene dataset\" paragraph 2", "quote": "The GSE66360 dataset including a total of 99 circulating endothelial cell samples that collected from 49 AMI and 50 control subjects, and this dataset was based on the GPL570 platform (Affymetrix Human Genome U133 Plus 2.0 Array)."}], "state": "complete"}, {"id": "claim-target-result", "statement": "After LASSO and SVM-RFE screening, four genes (ACSL1, CH25H, GPCPD1, and PLA2G12A) were identified as potential diagnostic biomarkers for AMI.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:36863716", "locator": "sections[0] \"Abstract\" paragraph 1", "quote": "After LASSO and SVM-RFE screening, four genes (ACSL1, CH25H, GPCPD1, and PLA2G12A) were identified as potential diagnostic biomarkers for AMI."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "After LASSO and SVM-RFE screening, four genes (ACSL1, CH25H, GPCPD1, and PLA2G12A) were identified as potential diagnostic biomarkers for AMI.", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:36863716"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "complete", "blocked_on": null, "description": "The GEO series accession resolves and its sample accessions are listed.
