The synthetic triterpenoid CDDO-imidazolide induces monocytic differentiation by activating the Smad and ERK signaling pathways in HL60 leukemia cells.
Synthetic triterpenoids, CDDO (2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid) or CDDO-imidazolide [2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid imidazolide (CDDO-Im)], induce cell differentiation in myeloid leukemia cells but their mechanism of action is not known. CDDO-Im induces monocytic differentiation markers, CD14, and nonspecific esterase in HL60 leukemia cells. We show that CDDO-Im act...
متن کاملThe synthetic triterpenoid CDDO-Imidazolide suppresses STAT phosphorylation and induces apoptosis in myeloma and lung cancer cells.
PURPOSE Excessive activity of the transcription factors known as signal transducers and activators of transcription (STAT) contributes to the development and progression of malignancy in many organs. It is, therefore, important to develop new drugs to control the STATs, particularly their phosphorylation state, which is required for their transcriptional activity. EXPERIMENTAL DESIGN Myeloma ...
متن کاملPI3K and ERK signaling pathways are involved in differentiation of monocytic cells induced by 27-hydroxycholesterol
27-Hydroxycholesterol induces differentiation of monocytic cells into mature dendritic cells, mDCs. In the current study we sought to determine roles of the PI3K and the ERK pathways in the 27OHChol-induced differentiation. Up-regulation of mDC-specific markers like CD80, CD83 and CD88 induced by stimulation with 27OHChol was significantly reduced in the presence of LY294002, an inhibitor of PI...
متن کاملThe triterpenoid CDDO induces apoptosis in refractory CLL B cells.
Chronic lymphocytic leukemia (CLL) cells develop chemo-resistance over time. Most anticancer agents function through induction of apoptosis, and therefore resistance against these agents is likely to be caused by selection for CLL cells with defects in the particular apoptosis pathway that is triggered by these drugs. Anticancer agents that function through alternative apoptotic pathways might ...
متن کاملThe synthetic triterpenoids, CDDO and CDDO-imidazolide, are potent inducers of heme oxygenase-1 and Nrf2/ARE signaling.
The synthetic triterpenoid 2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oic acid (CDDO) and its derivative 1-[2-cyano-3-,12-dioxooleana-1,9(11)-dien-28-oyl]imidazole (CDDO-Im) are multifunctional molecules with potent antiproliferative, differentiating, and anti-inflammatory activities. At nanomolar concentrations, these agents rapidly increase the expression of the cytoprotective heme oxygenase-1 ...
