BIRC5 and familial pancreatic carcinoma: We have previously identified a pancreatic cancer‐targeting ligand, SYENFSA (SYE), by screening an adenovirus library displaying random peptides against human pancreatic cancer cells and reported that a survivin promoter‐regulated adenovirus, displaying the SYE ligand (AdSur‐SYE), provided effective oncolysis of pancreatic ductal adenocarcinoma (PDAC) in a preclinical study.
