NEAT1 and gastric cancer: Zhou et al. [54] reported that NEAT1 targets and downregulates miR-500a-3p, promoting gastric cancer cell proliferation and invasion; Huang et al. [55] suggested that NEAT1 promotes pancreatic cancer progression by negatively regulating miR-506-3p; whereas Zhang et al. [56] showed that upregulation of NEAT1 is involved in the proliferation of glioma cells by negatively regulating miR-324-5p.
