1 In this study, we demonstrate that bortezomib significantly down-regulated IkappaBalpha expression and triggered NF-kappaB activation in MM cell lines and primary tumor cells from MM patients. Bortezomib NFKB inhibitor alpha Homo sapiens
2 Molecular mechanisms whereby bortezomib induced IkappaBalpha down-regulation were further examined. Bortezomib NFKB inhibitor alpha Homo sapiens
3 Bortezomib triggered phosphorylation of IkappaB kinase (IKKbeta) and its upstream receptor-interacting protein 2, whereas IKKbeta inhibitor MLN120B blocked bortezomib-induced IkappaBalpha down-regulation and NF-kappaB activation, indicating receptor-interacting protein 2/IKKbeta signaling plays crucial role in bortezomib-induced NF-kappaB activation. Bortezomib NFKB inhibitor alpha Homo sapiens
