Abstract

Multiple myeloma (MM) is the second most diffuse hematological malignancy and nowadays is stillincurable, despite the development of innovative therapies. MM cells accumulate in the bone marrow(BM) and establish vicious interactions with the surrounding normal cells, inducing them to promotetumor progression and the development of drug resistance. In this process, a crucial role is played bythe dyregulated Notch ligands Jagged1 and 2, whose overexpression boosts Notch both in MM cellsand in the BM cells. Here, we investigated how Jagged1/2 inhibition affects MM cells resistance to thestandard-of-care drug Bortezomib.
