Although arsenic can be poisonous, and chronic arsenic exposure from industrial or natural sources can cause serious toxicity, arsenic has been used therapeutically for more than 2,400 years. Thomas Fowler's potassium bicarbonate-based solution of arsenic trioxide (As(2)O(3)) was used empirically to treat a variety of disorders, and in 1878, was reported to reduce white blood cell counts in two...
Arsenic trioxide has been used as a therapeutic agent for acute promyelocytic leukemia and recently for some solid tumors. Although arsenic trioxide has been shown to significantly inhibit the growth of solid tumor cells in vitro, clinical trials indicate that arsenic trioxide alone is pool active against non-hematologic malignant diseases. To understand the mechanisms of arsenic resistance in ...
Background and Objective: Although arsenic trioxide has been shown to be a potential drug in treatment of APL, most notably in patients with relapsed APL, the underlying mechanisms remains unclear. In this study, the cytotoxic effect of ATO on APL cancer cells was evaluated. Materials and Methods: In this basic-applied study, the human leukemia (NB4) cell line was used as a model to evaluate th...
Arsenic is a ubiquitous trace element that has been shown to induce both systemic and carcinogenic effects. Epidemiological findings show that exposure to arsenic results in cardiovascular, gastrointestinal, and neurological disorders, as well as, various neoplastic diseases, such as, skin, lung, bladder, liver and kidney cancers. Although the mechanism of arsenic toxicity is not fully understo...
Mineral arsenicals have long been used in traditional medicines for various diseases, yet arsenic can be highly toxic and carcinogenic. Arsenic in traditional medicines typically comes from deliberate addition for therapeutic purposes, mainly in the form of mineral arsenicals, including orpiment (As2S3), realgar (As4S4), and arsenolite (contains arsenic trioxide, As2O3). Inorganic arsenic is no...
In this work, our study focused on As(2)O(3) action in view point of telomere. Results showed that treatment of human gastric cancer MGC-803 cells with arsenic trioxide could cause up-regulation of telomeric repeat binding factor TRF1 and TRF2 mRNA and protein levels, and induced G2/M phase arrest and cell apoptosis. At the same time, telomere length shortening and telomerase inhibitory were no...
Introduction: Arsenic Trioxide is effective and approved for treatment of relapsed or refractory APL cases to ATRA but its effects in new cases of APL is not clear and needs long term follow up to disclose the role of this drug in treatment of APL in combination with chemotherapy/ATRA or alone. Material and methods: we studied 111cases of APL (94 new case and 17 relapsed) diagnosed by morpholog...
UNLABELLED INTRODUCTION In the relapsed setting, arsenic trioxide remains the backbone of treatment. Scant literature exists regarding treatment of relapsed acute promyelocytic leukemia in patients with renal failure. To the best of our knowledge we are the first to report a safe and effective means of treatment for relapsed acute promyelocytic leukemia in the setting of advanced renal failu...
Background and Aim: Acute promyelocytic leukemia (APL) is a distinct subtype of acute myeloid leukemia. APL is characterized by a balanced reciprocal translocation between chromosomes 15 and 17, t(517)). Important therapeutic strategies for this disease are ATRA and Arsenic trioxide. To eliminate tumor cells with arsenic, high dose of arsenic is needed. But high dose is toxic for normal tissue....
We report a patient with an initial relapse of acute promyelocytic leukemia (APL) who achieved a second complete remission (CR) after treatment with arsenic trioxide. The patient, a 66-year-old woman diagnosed as having relapsed APL, received arsenic trioxide intravenously at a dose of 10 mg/day. At day 36, the patient achieved a second CR. The side effects were slight neuralgia and mild skin e...
