The prognostic analysis results using the Kaplan-Meier plotter database indicated that the upregulated expression of 11 DEGs (AGTR1, ATG14, CDO1, CFL2, CNN1, CNTN1, COX7A1, DDR2, LAYN, RASSF8, and ZNF471) significantly affected the overall survival rate of patients with GC (p < 0.05) (Figure 3B). Here, COX7A1 is linked to gastric cancer.
