(a) NEAT1 acts as a sponge for miR‐181a‐5p—high NEAT1 levels inversely correlate with miR‐181a‐5p levels—leading to an upregulation of high‐mobility group box 2 (HMGB2; Li et al., 2018a)—a protein known for being upregulated and being the driver for tumorigenesis in several cancer types (Fu et al., 2018; Kwon et al., 2010). This evidence concerns the gene NEAT1 and cancer.
