p53 accumulation is also implicated in the mechanism by which arsenic trioxide treatment induces apoptosis and G 1 phase arrest in human T-cell lymphotropic virus type 1-infected cells. Arsenic trioxide has shown substantial efficacy in treating both newly diagnosed and relapsed patients with acute promyelocytic leukemia (APL). As a single agent, it induces complete remissions, causing few adverse effects and only minimal myelosuppression. These successes have prompted investigations to elucidate the mechanisms of action underlying Other independent mechanisms linked to the intracellular biochemical environment may contribute to the induction of apoptosis, partial cellular differentiation, growth arrest, and inhibition of angiogenesis by arsenic. 7 For example, inducing expression of PML-RARα does not change the sensitivity of U937 cells, a non-APL leukemic cell line, to ATO (W.H. Miller, unpublished data).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.

N2 - Background: The ancient drug, arsenic, has remarkable efficacy in the treatment of relapsed acute promyelocytic leukemia (APL) and this success has led to exploration of its use in other malignancies.

Our results provided a new insight for investigation of arsenic trioxide and report a novel mechanism for its action. We postulate that arsenic trioxide enters the cytosol, acts on the AE2 protein and facilitates anion exchange activity. TY - JOUR.

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.

Mechanisms of Action of the Anti-Cancer: Garnier Nicolas:

Arsenic Trioxide also damages or degrades the fusion protein promyelocytic leukemia (PML) - retinoic acid receptor (RAR) alpha. 2002-07-01 · These successes have prompted investigations to elucidate the mechanisms of action underlying these clinical responses. Substantial data show that arsenic trioxide produces remissions in patients with APL at least in part through a mechanism that results in the degradation of the aberrant PML-retinoic acid receptor alpha fusion protein. Arsenic Trioxide is indicated for induction of remission and consolidation in patients with acute promyelocytic leukemia (APL) who are refractory to, or have relapsed from, retinoid and anthracycline chemotherapy.
