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 these clinical responses.

To study the anti-tumor effect of arsenic trioxide on the HepG2 human hepatocellular carcinoma cell line, and to explore its mechanism of action. The MTT assay was used to determine the inhibitory effect of As2O3 on HepG2 cells at various As2O3 concentrations. The expression of p-JNK, caspase-3 and PARP was detected by Western blots. As2O3 markedly inhibited the growth of the HepG2 cells and

The mechanism of action of Arsenic Trioxide is not completely understood. 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 (As2O3, ATO) is a very efficacious, clinically established agent for the treatment of acute promyelocytic leukaemia, and also potentially useful against other haematological and non-haematological malignancies. Nonetheless, the relative resistance of many tumour cell types requires the generation of sensitizing strategies. Another mechanism by which arsenic trioxide induces apoptosis is by activating death-effector molecules, such as caspases, through induction of cytochrome C. Arsenic trioxide also downregulates Bcl-2, an antiapoptotic molecule, thus causing gene-directed cellular “suicide.” 3 Metabolites of this compound have also been thought to play a role in its mechanism of action, with some The present study aimed to evaluate the effect of arsenic trioxide (ATO), a traditional Chinese medicine, on cervical cancer cells and its underlying mechanism.
