This study aimed to find critical genes/pathways in GC pathogenesis to be used as biomarkers or therapeutic targets.  \nMethods Differentially expressed genes were explored between human gastric cancerous and noncancerous tissues, and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes signaling pathway enrichment analyses were done. Hub genes were identified based on the protein–protein interaction network constructed in the STRING database with Cytoscape software. The hub genes were selected for further investigation using GEPIA2 and DrugBank databases. Results Ten overexpressed hub genes in GC were identified in the current study, including FN1, TP53, IL-6, CXCL5, ELN, ADAMTS2, WISP1, MMP2, CTGF, and THBS1. The study demonstrated the PI3K-Akt pathway’s central involvement in GC, with pronounced alterations in essential components. Survival analysis revealed significant correlations between CTGF, FN1, IL-6, THBS1, and WISP1 overexpression and reduced overall survival times in GC patients.  \nConclusion A mutual interplay emerged, where PI3K-Akt signaling could upregulate certain genes, forming feedback loops and intensifying cancer phenotypes. The interconnected overexpression of genes and the PI3K-Akt pathway fosters gastric tumorigenesis, suggesting therapeutic potential. DrugBank analysis identified limited FDA-approved drugs, advocating for further exploration while targeting these hub genes could reshape GC treatment. The identified genes could be novel diagnostic/prognostic biomarkers or potential therapeutic targets for GC, but further clinical validation is required.  \nKeywords Biological networks · Biomarker · Differentially expressed genes · Gastric cancer · Therapeutic target  \n1 Introduction  \nWith a poor prognosis, gastric cancer (GC) is the fourth most frequent malignancy worldwide and the fifth most common cause of cancer-related mortality [1]. There have been multiple studies investigating the connection between different risk factors and the development of GC, but the exact molecular network processes are yet to be fully understood [2] .  \n* Negar Mottaghi-Dastjerdi, [Mottaghi.n@iums.ac.ir |](Mottaghi.n@iums.ac.ir |1Department of Pharmacognosy and)[1](Mottaghi.n@iums.ac.ir |1Department of Pharmacognosy and)[Department of Pharmacognosy and](Mottaghi.n@iums.ac.ir |1Department of Pharmacognosy and) Pharmaceutical Biotechnology, School of Pharmacy, Iran University of Medical Sciences, Tehran, Iran. 2Nuclear Agriculture Research School, Nuclear Science and Technology Research Institute (NSTRI), Karaj, Iran. 3Behestan Innovation Factory, Tehran, Iran. 4School of Medicine, Iran University of Medical Sciences, Tehran, Iran.  \nDiscover Oncology  \n(2024) 15:344  \n| [https://doi.org/10.1007/s12672-024-01225-4](https://doi.org/10.1007/s12672-024-01225-4)  \nUnderstanding the molecular mechanisms involved in the development of GC can help in finding potential targets for early detection and classification, which may improve patient survival rates.  \nCarcinogenesis is a complex process that entails numerous genetic and epigenetic alterations [3]. The most common typeof GC isadenocarcinoma, accounting for about 95% of cases [4]. Numerous studies have been conducted on the epigenetic and genetic changes in various types of GC, with a particular focus on changes in oncogenes, tumor suppressor genes, DNA repair genes, and cell cycle regulators [5].
