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. 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. Mechanism of action. The mechanism of action of Arsenic Trioxide is not completely understood.

Arsenic trioxide causes morphological changes and DNA fragmentation characteristic of apoptosis in NB4 human promyelocytic leukemia cells in vitro. Arsenic trioxide also causes damage or degradation of the fusion protein PML/RAR-alpha. 3.3 Mechanism of action Arsenic trioxide has been described as an ‘anticancer missile with multiple warheads’, referring to its complex and multifaceted mechanism of action ( Figure 1) [25]. With the elucidate the mechanism of action of AT. An important study indicated dose-dependent dual effects, with preferential Arsenic trioxide (ATO)‑induced hepatotoxicity limits the therapeutic effect of acute myelogenous leukemia treatment. Magnesium isoglycyrrhizinate (MgIG) is a natural compound extracted from licorice and a hepatoprotective drug used in liver injury.

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 mechanism of action in apl revealed SINGAPORE (Reuters) Apr 09 - Scientists in China have demonstrated how arsenic can treat leukemia by … The mechanism of action of Arsenic Trioxide is not completely understood.

The clinical results achieved with arsenic trioxide (As2O3) in acute promyelocytic leukemia (APL) have prompted investigations to determine the mechanisms mediating its activity. This ‘bedside to bench’ approach has shown that As2O3 has multiple targets. The interaction of As2O3 with sulphydryl groups on these targets seems to be a common mechanism of action. This is consistent with the

With the elucidate the mechanism of action of AT. An important study indicated dose-dependent dual effects, with preferential 2020-11-11 · Based on the mechanism of action [see Clinical Pharmacology ( 12.1) ] and findings in animal studies, arsenic trioxide injection can cause fetal harm when administered to a pregnant woman. 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. Hong SH, Yang Z, Privalsky ML. Mol. Cell.

2020-09-24 · Arsenic trioxide has shown a strong anti-tumor effect with little toxicity when used in the treatment of acute promyelocytic leukemia (APL). An effect on glioma has also been shown. Its mechanisms include regulation of apoptosis and autophagy; promotion of the intracellular production of reactive oxygen species, causing oxidative damage; and inhibition of tumor stem cells. However, glioma

2013-05-14 · Since the introduction of all-trans retinoic acid (ATRA) and arsenic trioxide (As2O3) for the treatment of acute promyelocytic leukemia (APL), the overall survival rate has improved dramatically. However, relapse/refractory patients showing resistance to ATRA and/or As2O3 are recognized as a clinically significant problem. Genetic mutations resulting in amino acid substitution in the retinoic
