Introduction: The prevalence of gastrointestinal cancers, especially gastric and colorectal cancers, is increasing. Gastric cancer is the most common gastrointestinal cancer in Iran and the age of esophageal and colon cancers onset has decreased in Iran. Therefore, it is important to study the factors and proteins involved in these cancers. Use of computational tools is an effective way to study protein networks and identify the important proteins involved in these diseases.
Method: At first identified proteins from esophageal, gastric and colon cancers were extracted from relevant databases and articles; then, the Protein-Protein Interaction (PPI) networks were mapped and analyzed for cross-linking and determination of key proteins using servers and software such as STRING 11.0, Cytoscape 3.7.3, NDEx 2.4.3, and UniProt. The CentiScaPe 2.2 plugin was used by examining the centrality indices (Betweenness, Closeness, Degree) and the CytoHubba plugin was used by different centrality indices for determination of the key nodes and the central common proteins. Finally, after investigation of the expression profiles of proteins with high centrality indices using GTEx v8, Expression Atlas, and GEPIA2, the final common proteins were determined in all three cancers.
Results: The results showed that PLK1, CCNB1, CCNA2, BUB1B, and CDK1 proteins are the central common proteins in all three tissues. These proteins are highly correlated (R => 0.8) with each other and have significant expression differences in normal and cancerous tissues.
Conclusion: PLK1, CCNB1, CCNA2, BUB1B, and CDK1 proteins can be used as diagnostic and therapeutic markers for esophageal, gastric, and colon cancers. Further studies on these proteins will have a bright future for the treatment of various types of gastrointestinal cancer.
