Kaplan–Meier survival analysis of data obtained from the GEO database demonstrated that high CPNE3 levels were associated with poorer OS (p = 0.0032) and FP (p = 0.012) in patients with GC exhibiting high YAP1 mRNA expression, whereas OS and FP in patients with GC with low YAP1 levels were not significantly different between different CPNE3 levels (Supplemental Fig. S4F–I). This evidence concerns the gene YAP1 and gastric cancer.
