We used the TISDB database to investigate the relationship of PDCD10 expression with a wide range of tumor molecular subtypes and discovered that it was positively correlated with esophageal carcinoma (ESCA), lung squamous cell carcinoma (LUSC), and stomach adenocarcinoma (STAD) (p < 0.05; Figure 1(b)). This evidence concerns the gene PDCD10 and gastric adenocarcinoma.
