CD274 and squamous cell lung carcinoma: In gastric cancer, NKX2-1-AS1 is closely correlated with oncogenesis and progression.[35] In human lung carcinoma, NKX2-1-AS1 could negatively regulated CD274/PD-L1, cell interaction genes, and cell migration.[36] We reported that SFTA1P and NKX2-1-AS1 as an immune-related competing endogenous lncRNA in lung squamous cell carcinoma for the first time.
