Abstract: BACKGROUND: Cell surface molecules play important roles in cell signal transduction pathways during microbial infection. OBJECTIVE: In this study, the expression and the functions of CD59 was investigated in H. pylori infected gastric cancer (GC). METHODS AND RESULTS: The differential expression of CD59 and the influence of H. pylori on the expression of CD59 were analyzed via bioinformatics through Gene Set Enrichment in GC. In addition, the expression of CD59 in GES-1, AGS cells and GC tissues infected with H. pylori was confirmed by Western blot. Bioinformatics results and H. pylori infection experiments showed CD59 decreased obviously in H. pylori infected GC cells and tissues. The expression of CD59 was linked to the survival rate of GC patients, and influenced various immune cells in the immune microenvironment of GC. CD59 interacts with other genes to form a network in H. pylori infected GC. Certainly, CD59 decreased significantly in H. pylori infected GC tissues, GES-1 and AGS cells in vitro. CONCLUSION:H. pylori infection could influence the expression of CD59 in GC indicating that CD59 may be a promising treatment target.
