TP53 and diffuse large B-cell lymphoma: The induction of a senescent phenotype triggered by increased levels of miR-520c-3p was further supported by the enhanced activity of the senescence marker ß-galactosidase (Figure 2C) and was confirmed by other hallmarks of senescence such as elevated p16 and p53 protein levels and decreased HuR expression [36] in HeLa and DLBCL cells (Figure 2D).
