The correlation between AMBRA1 and the cell senescence-related genes caused by the DDB1/FOXO3/CDKN1/CCND1 pathway in gastric cancer samples was explored, among which DDB1, FoxO3A, p53, CRK, and CDKN1B, were highly correlated as the enrichment result mentioned above (Figures 5D–I). Here, CDKN1B is linked to gastric cancer.
