The knowledge accumulated over the last decade on B-cell-derived non-Hodgkin lymphoma (B-NHL) pathogenesis has led to the identification of several molecular abnormalities, opening new perspectives in the design of novel therapies. Indeed, drugs targeting specific biochemical pathways critical for B-NHL cell survival, proliferation, and fitness within the malignant microenvironment are now available to the clinician: the B-cell receptor signaling inhibitors of BTK, PI3Kδ, ζ, γ, and SYK or the pro-apoptotic BH3-mimetics are clear examples of it. Moreover, it is emerging that malignant B-cell growth is sustained not only by mutations in oncogenes/tumor suppressors but also by the "addiction" to nononcogene (ie, nonstructurally altered) molecules. In this regard, a consistent body of data has established that the Ser/Thr kinases CK1, CK2, and GSK3 are involved in malignant lymphocyte biology and act as pro-survival and signaling-boosting molecules, both in precursor and mature B-cell tumors. Currently, an experimental and clinical groundwork is available, upon which to design CK1-, CK2-, and GSK3-directed antilymphoma/leukemia therapies. In this review, we have examined the main features of CK1, CK2, and GSK3 kinases, summarized the data in B-NHL supporting them as suitable therapeutic targets, and proposed a perspective on potential future research development.
