An increase in circulatory levels of inflammatory cytokines has been found in patients with CAD, while the molecular mechanisms of inflammation still remain elusive. This study was designed to identify differentially expressed genes (DEGs), and to explore the molecular mechanism and hub genes that are involved in the effects of Lactobacillus plantarum 299v (Lp299v) supplementation. Microarray dataset (GSE156357) was downloaded from the Gene Expression Omnibus (GEO) database. The DEGs were identified by the R software. Then, the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses and construction of protein-protein interaction (PPI) network were performed by DAVID, STRING, and Cytoscape software. In daily alcohol user (DAU) group, 7,541 DEGs were identified, including 206 up-regulated and 7,335 down-regulated DEGs. In non-daily alcohol user (non-DAU) group, 2,799 DEGs were identified (2,491 up-regulated and 308 down-regulated DEGs). The GO enrichment analysis revealed that miosis was up-regulated and immune response was down-regulated. The KEGG enrichment analysis showed that Lp299v supplementation reduced the levels of chemotactic cytokines, and weakened immune response. Proteins of G protein-coupled receptor, inflammatory response, regulation of cell proliferation and apoptosis-related proteins were found in the PPI network. The hub genes were associated with G protein-coupled receptor, inflammatory response, and cell proliferation and apoptosis. The weighted gene co-expression network analysis (WGCNA) enriched the DEGs in 4 modules. This study indicated the expressions of chemokine receptors and regulation of immune response in the Lp299v supplementation. Meanwhile, it was supposed that chemokine receptors may have a cellular effect.", "claims": [{"id": "claim-method", "statement": "Benjamini–Hochberg adjusted P was used to control false discovery rate (FDR).", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36152115", "locator": "sections[4] \"Identification of DEGs\" paragraph 2", "quote": "Benjamini–Hochberg adjusted P was used to control false discovery rate (FDR)."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The datasets generated during and/or analyses during the current study are available in the GEO database (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE156357).", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36152115", "locator": "sections[20] \"Availability of data and materials\" paragraph 2", "quote": "The datasets generated during and/or analyses during the current study are available in the GEO database (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE156357)."}], "state": "complete"}, {"id": "claim-target-result", "statement": "After normalization, 7541 DEGs were identified in the DAU group (206 up-regulated and 7335 down-regulated DEGs).", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:36152115", "locator": "sections[10] \"Identification of DEGs\" paragraph 2", "quote": "After normalization, 7541 DEGs were identified in the DAU group (206 up-regulated and 7335 down-regulated DEGs)."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "After normalization, 7541 DEGs were identified in the DAU group (206 up-regulated and 7335 down-regulated DEGs).", "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:36152115"], "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.
