In this section, we summarize and discuss the role of the NEAT1/miRNA/target axis in circulatory system tumors, including hemangioma, acute myeloid leukemia, T-cell acute lymphoblastic leukemia, diffuse large B-cell lymphoma, Hodgkin's lymphoma, and multiple myeloma (Table 4). This evidence concerns the gene NEAT1 and Hodgkins lymphoma.
