LIFR and non-small cell lung carcinoma: LncRNA LIFR-AS1 regulates the development of gastric cancer cells by sponging miR-4698 (Zhao et al. 2021); Yang et al. found that the lncRNA BRCAT54 can suppress tumorigenesis in non-small cell lung cancer by binding to related factors or genes (Yang et al. 2021), and some researchers found that lncRNA H19 suppresses the inflammatory response of human retinal epithelial cells by regulating related factors (Luo et al. 2021).
