The role miR-155-5p has been studied extensively in nodal B-cell non-Hodgkin lymphomas and is linked to activation of the intracellular signaling pathway PI3K-Akt pathway [10] and increased lymphoma cell motility [49], and its expression is associated with NF-κB activity in nodal DLBCL [48]. This evidence concerns the gene NFKB1 and lymphoma.
