Despite quite a few mechanisms including the inflammatory mediator, exosomes, and mitochondrial dysfunction, having been confirmed in the existing research studies we still find it obscure about the overall situation of gene co-expression that how they can affect the pathological process of SIC. Thus, we intended to find out the crucial hub genes, biological signaling pathways, and infiltration of immunocytes underlying SIC. It was weighted gene co-expression network analysis that worked as our major method on the ground of the gene expression profiles: hearts of those who died from sepsis were compared to hearts donated by non-failing humans which could not be transplanted for technical reasons (GSE79962). The top 25 percent of variant genes were abstracted to identify 10 co-expression modules. In these modules, brown and green modules showed the strongest negative and positive correlation with SIC, which were primarily enriched in the bioenergy metabolism, immunoreaction, and cell death. Next, nine genes (<jats:italic>LRRC39<\/jats:italic>, <jats:italic>COQ10A<\/jats:italic>, <jats:italic>FSD2<\/jats:italic>, <jats:italic>PPP1R3A<\/jats:italic>, <jats:italic>TNFRSF11B<\/jats:italic>, <jats:italic>IL1RAP<\/jats:italic>, <jats:italic>DGKD<\/jats:italic>, <jats:italic>POR<\/jats:italic>, and <jats:italic>THBS1<\/jats:italic>) including two downregulated and seven upregulated genes which were chosen as hub genes that meant the expressive level of which was higher than the counterparts in control groups. Then, the gene set enrichment analysis (GSEA) demonstrated a close relationship of hub genes to the cardiac metabolism and the necroptosis and apoptosis of cells in SIC. Concerning immune cells infiltration, a higher level of neutrophils and B cells native and a lower level of mast cells resting and plasma cells had been observed in patients with SIC. In general, nine candidate biomarkers were authenticated as a reliable signature for deeper exploration of basic and clinical research studies on SIC.<\/jats:p>","DOI":"10.3389\/fgene.2021.812509","type":"journal-article","created":{"date-parts":[[2021,12,24]],"date-time":"2021-12-24T09:11:54Z","timestamp":1640337114000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Identification of Crucial Genes and Infiltrating Immune Cells Underlying Sepsis-Induced Cardiomyopathy via Weighted Gene Co-Expression Network Analysis"],"prefix":"10.3389","volume":"12","author":[{"given":"Juexing","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenhua","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shangneng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangyue","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Gong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,12,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"681","DOI":"10.1161\/circulationaha.119.039642","article-title":"Loss of Protein Phosphatase 1 Regulatory Subunit PPP1R3A Promotes Atrial Fibrillation","volume":"140","author":"Alsina","year":"2019","journal-title":"Circulation"},{"key":"B2","doi-asserted-by":"publisher","first-page":"6312","DOI":"10.1038\/s41598-017-06395-6","article-title":"Ryanodine Receptors Are Part of the Myospryn Complex in Cardiac Muscle","volume":"7","author":"Benson","year":"2017","journal-title":"Sci.
