AEBP1 is differentially expressed in various tumors. However, the correlation between AEBP1 and immune cell infiltration in gastric cancer remains unclear. Kaplan-Meier survival curves were used to evaluate the relationship between AEBP1 expression and overall survival and progression-free survival. The relationship between AEBP1 expression and infiltrating immune cells, and their corresponding gene marker sets was examined using the TIMER database.The expression of AEBP1 was lower in gastric

High AEBP1 gene expression and high levels of AEBP1 gene methylation were correlated with high-grade malignant tumor and old TNM stage. In addition, in gastric cancer, there was a positive correlation between AEBP1 expression and immune infiltrating cells, including neutrophils, CD8 + T cells, and CD4 + T cells, as well as immune-related genes, including CD2, CD3D, and CD3E. Methylation sites such as cg00009293, cg08495088, cg12955216, cg10480062, cg06852744 and cg12978582 were positively correlated with low expression of AEBP1. AEBP1 may be a potential tumor suppressor gene in GC and a potential novel therapeutic target and predictive biomarker for GC. AEBP1 likely plays an important role in immune cell infiltration.
