lncRNA NEAT1 regulates the permeability of the blood‐tumor barrier via miR‐181d‐5p‐mediated expression changes in ZO‐1, occludin, and claudin‐5.18 The lncRNA NEAT1 regulates epithelial to mesenchymal transition and radioresistance in through miR‐204/ZEB1 axis in nasopharyngeal carcinoma.19 The results of our study showed that miR‐384 was downregulated in HCC tissues and cell lines. The gene discussed is NEAT1; the disease is hepatocellular carcinoma.
