This study utilized ShinyGO (version 0.80) for gene enrichment analysis with statistical analysis of the selected features. The PPI-network analysis was performed using the Maximal Clique Centrality (MCC) approach, along with the CytoHubba plugin for identifying hub nodes. The PPI network was visualized using Cytoscape version 3.7.</p><p><strong>Results: </strong>A total of 145 target genes of Pf3D7 were predicted, with the following genes repeatedly targeted: conserved Plasmodium proteins, conserved Plasmodium membrane proteins, PfEMP1, rifin, RAD54, E3 ubiquitin-protein ligase, and transcription factors related genes. Outputs of ShinyGO included enriched GO pathways of 62 uniquely identified Pf3D7 genes with detailed descriptions and visualized networks. For overlapping relationships, a hierarchical clustering tree of enriched gene sets was carried out, along with a genome plot for representing the chromosomal locations of these genes. According to their coding-noncoding distribution chart, most of these genes were found to be members of the coding gene family. Additionally, PPI-network analysis reported the top 10 hub nodes: PFE0400w, MAL13P1.380, MAL7P1.167, PFD0900w, PF11_0243, PFE0440w, PFE1120w, MAL13P1.315, PF08_0126, and MAL8P1.23. Three KEGG pathway diagrams of pfa 05144 for Malaria, pfa 03440 for homologous recombination, and pfa 00750 for vitamin B6 metabolism with identified Pf3D7 genes were drawn and highlighted in red.</p><p><strong>Conclusion: </strong>The important target genes of Plasmodium falciparum 3D7 were identified by carrying out a trans-kingdom investigation, thus offering preliminary insights into the potential of erythrocytic miRNAs-mediated trans-kingdom regulation.</p>","PeriodicalId":38067,"journal":{"name":"MicroRNA (Shariqah, United Arab Emirates)","volume":" ","pages":"147-169"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
