Abstract
Background: Gastric cancer (GC) is one of the most common malignant tumors and a leading cause of cancer-related death worldwide. Although advances in surgical techniques and novel treatment techniques such as immunotherapy have improved the prognosis of many tumors, the effectiveness of treatment for advanced GC patients is still limited. Methods: Immunohistochemistry (IHC) staining analysis was conducted to compare the expression of ALDOA and ENO1 in GC tissues and adjacent normal tissues, complemented by bioinformatics analysis using GEPIA, LinkedOmics, and TIMER databases to explore their association with glycolysis and immune cell infiltration. A survival prediction nomogram was constructed based on Cox proportional hazard model data to evaluate prognostic significance. Results: In this study, through IHC staining analysis, it was observed that the expression levels of ALDOA and ENO1 in GC tissues were significantly higher than those in adjacent normal tissues. Moreover, the aberrant expression of ALDOA/ENO1 was associated with a poor prognosis in GC patients. Bioinformatics analysis revealed a positive correlation between ALDOA and ENO1 expression, both intricately associated with glycolysis pathway activation. A survival prediction nomogram, constructed based on the univariate analysis of data from the Cox proportional hazard model, demonstrated that the expression of ALDOA and ENO1 significantly impacts the prognosis of GC patients. Conclusions: ALDOA/ENO1 may play a crucial role in GC, which may potentially offer new perspectives and directions for the development of targeted therapies specifically designed for GC patients.
