For instance, DICER-AS1 downregulation was reported to be associated with advanced staging in gastric cancer [69]; NPPA-AS1 downregulation was associated with tumor aggressiveness in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) [70]; and tumor-specific downregulation of ENTPD3-AS1 was reported to be associated with poorer patient overall survival (OS) and relapse-free survival (RFS) in LUAD [71], followed by the subsequent biological demonstration of ENTPD3-AS1′s suppressive role in LUAD cell growth and migration. This evidence concerns the gene NPPA and cervical squamous cell carcinoma.
