The inhibitor of PI3K-AKT-mTOR pathway, such as Rad001, has not shown therapeutic efficacy as a single agent in prostate cancer. Arsenic trioxide induces the autophagic pathway in prostate cancer cells. We identified Arsenic trioxide can synergize with Rad001 to induce cytotoxicity of prostate cancer cells. Moreover, we identified synergistic induction of autophagy and apoptosis as the underlyi...

the aim of the present study was to evaluate vitamin c (vc) as a potent natural antioxidant to mitigate the genotoxic effects of arsenic trioxide and sodium fluoride in swiss albino mice in vivo. the study was divided into eight groups consisting of control treated with normal saline (group i), group ii, iii, iv, v, vi, vii and the vc group with only vitamin c (500 mg/kgbw). arsenic trioxide (4...

This review outlines briefly the history and present status of the problem of carcinogenic, teratogenic and mutagenic effects of arsenic. Discrepancies between clinical observations and positive results of epidemiological studies and the experimental induction of cancer by arsenic are discussed. The present knowledge of the mechanism of teratogenic and mutagenic effects of arsenic is analyzed. ...

A micro burette, micro pipette, and methods for their use in quantitative toxicological investigations on mandibulate insects are described. It is suggested that the form of curves relating speed of toxic action to dosage may be explained by postulating suitable changes in rate of distribution, excretion, and cell penetration of poison as dosage varies. The speed of toxic action of pentavalent ...

The discovery of arsenic contamination in groundwater has challenged efforts to provide safe drinking-water to households in rural Bangladesh. Two nationally-representative surveys in 2000 and 2002 investigated water-usage patterns, water-testing, knowledge of arsenic poisoning, and behavioural responses to arsenic contamination. Knowledge of arsenicosis rose between the two surveys among women...

Tsuji et al. (2004) provide a detailed discussion of the available data for deriving an acute/subchronic oral reference level for arsenic. As part of their analysis, they summarize a series of studies in which arsenic trioxide was administered to patients with acute promyelocytic leukemia (APL) who were non-responsive to standard retinoic acid therapy. arsenic was administered at doses ranging ...

Acute promyelocytic leukemia (APL) has unique clinical, cytogenetic, and molecular features and is one of the most potentially curable human malignancies. The current standard treatment given to patients with newly diagnosed APL consists of all-trans retinoic acid and anthracycline-based cytotoxic chemotherapy, which is highly effective for remission induction. However, despite the potential fo...
