1 Dexamethasone induces apoptosis of multiple myeloma cells in a JNK/SAP kinase independent mechanism. Dexamethasone mitogen-activated protein kinase 8 Homo sapiens
2 Taken together, our findings suggest that SAPK/JNK activation is not required for apoptosis in MM cells, and that there are at least two distinct apoptotic signaling pathways: (i) SAPK/JNK-associated, which is induced by IR and unaffected by IL-6; and (ii) SAPK/JNK-independent, which is induced by Dex, associated with downregulation of MAPK and p70S6K and inhibited by IL-6.
