CDC37 and mantle cell lymphoma: On the opposite, in MCL cell lines Granta-519 and Jeko-1 we observed lower basal levels of phospho Ser13 Cdc37 but a dose-dependent increase upon bortezomib treatment; differently, in the MCL cell line Rec-1, the levels of phospho Ser13 Cdc37 were - like in MM cells - higher and not inducible.
