ZNF407 and cancer: The alias of LINC00909 is recognized as ZNF407-AS1, which represents the antisense strand of ZNF407. However, our study did not explore the potential impact of LINC00909 on the stability of ZNF407 mRNA and whether it could consequently facilitate the cancer stemness of tumorigenicity of pancreatic ductal adenocarcinoma (PDAC).
