This study performed a comprehensive bioinformatics and machine learning approach to identify key protein biomarkers for gastric cancer and elucidate their potential functions. Gastric cancer-related datasets were obtained from the NCBI Gene Expression Omnibus database. Differential expression analysis identified 171 genes with noticeable differences between control and tumor samples.  \nUtilizing LASSO, SVM-RFE, and RF algorithms, five genes—INHBA, DPT, ADH7, FBP2 and GPR155—were identified as potential biomarkers. A logistic regression model demonstrated the highest performance among ten machine learning models constructed using these five genes. Shapley additive explanations (SHAP) were employed to illustrate the detailed contribution of the pivotal genes to the logstics model. Gene set enrichment analysis and gene set variation analysis were then used to find out the functional roles of these genes in gastric cancer cells. At length, we revealed the distinctive effects of signature genes on immune cell infiltration and patient diagnosis. In conclusion, the identified proteins have the potential to serve as diagnostic biomarkers and provide treatment value for gastric cancer. This study offers a comprehensive, data-driven approach to uncover critical molecular targets for improved detection and management of this deadly disease.  \nKeywords Gastric cancer, INHBA, DPT, ADH7, FBP2, GPR155, Biomarkers, Machine learning, SHapley additive exPlanations  \n1 Introduction  \nThe based on GLOBOCAN 2022 data, gastric cancer (GC) recorded approximately 968,000 new cases and 659,000 deaths in 2022, ranking fifth in both incidence and mortality rates [1]. Despite it has decline in incidence and mortality, the incidence of GC among young individuals is steadily increasing annually, presenting a persistent global health challenge [2]. Adenocarcinoma accounts for over 95% of GC cases. High-risk factors for GC include consumption of nitrite-rich foods and moldy foods, Helicobacter pylori infection [3], excessive alcohol intake, smoking and other unhealthy behaviors [4,  \n© The Author(s) 2025.
