We also observed statistically significant relationships between the ZP3-Cancer expression level and tumor grade and the clinical parameters OS and DSS in head and neck squamous cell carcinoma (HNSC; Supplementary Figure S3A), tumor grade and OS and DSS in pancreatic ductal adenocarcinoma (PAAD; Supplementary Figure S3B), and tumor stage and OS in lung adenocarcinoma (LUAD; Supplementary Figure S3C). Here, ZP3 is linked to pancreatic ductal adenocarcinoma.
