Arsenic trioxide (As 2 O 3) and IFN-α were recently demonstrated to induce apoptosis in 2 HTLV-1–transformed cells.11 To investigate the mechanism of action of arsenic trioxide, associated or not associated with IFN-α, we treated with these chemicals a series of HTLV-1–immortalized (IL-2–dependent) cells (Bes, Boul), HTLV-1–transformed (IL-2–independent) cells (C8166, HUT-102, MT-2

Miller, unpublished data). There is no difference in arsenic sensitivity between ATRA-resistant APL cells that fail to express or rapidly It has been proposed that ATO acts through activation of Jun N-terminal kinase (JNK), activator protein-1, and inhibition of dual-specificity phosphatases, and evidence is accumulating that JNK activation is an important event in arsenic-induced apoptosis. Arsenic trioxide has recently carved out a role in cancer therapy because it can induce electron leakage along the respiratory chain 99. It triggers apoptosis in different cancer cells, including These successes have prompted investigations to elucidate the mechanisms of action underlying these clinical responses.

The mechanism of action of arsenic trioxide is not well understood. There is speculation that it causes death of leukemia cells via morphological changes and DNA fragmentation. Arsenic Trioxide also damages or degrades the fusion protein promyelocytic leukemia (PML) - retinoic acid receptor (RAR) alpha.

Boise; Glutathione and Glutathione Utilizing Enzymes Are Key Determinants in the Sensitivity of Myeloma Cells to Arsenic Trioxide as Well as Its Mechanism of Action..

The mechanisms by which arsenic-containing compounds kill cells and reasons for selective killing of only certain types of cancer cells such as APLs have recently been delineated. This knowledge was gained in parallel with Mechanism of action. The mechanism of action of arsenic trioxide is not completely understood. Arsenic trioxide causes morphological changes and deoxyribonucleic acid (DNA) fragmentation characteristic of apoptosis in NB4 human promyelocytic leukaemia cells in vitro. Arsenic trioxide; Mechanism of action. Arsenic trioxide causes morphologic changes and DNA fragmentation characteristics of apoptosis in NB4 human promyelocytic leukemia cells in vitro.

Arsenic trioxide was embryolethal and teratogenic in rats when administered on gestation day 9 at a dose approximately 10 times the recommended human daily dose on a mg/m 2 basis ( see Data ). Arsenic trioxide is a potent inhibitor of the interaction of SMRT corepressor with Its transcription factor partners, including the PML-retinoic acid receptor alpha oncoprotein found in human acute promyelocytic leukemia.
