Arsenic (+3 oxidation state) methyltransferase (As3mt) plays a central role in the enzymatically catalyzed conversion of inorganic arsenic into methylated metabolites. Most studies of the metabolism and disposition of arsenicals following exposure to inorganic arsenic focus on the formation and

The purpose of present study was to characterize the endoplasmic reticulum stress and generation of ROS in rat liver RLC-16 cells by exposing to trivalent dimethylarsinous acid (DMAIII) and compared with that of trivalent arsenite (iAsIII) and monomethylarsonous acid (MMAIII).

Inorganic arsenic is a well-documented, exposure relevant human carcinogen. A promising starting point to further understand the mechanisms behind inorganic arsenic carcinogenicity might be a formation of reactive, highly toxic metabolites during human arsenic metabolism. This study characterises the toxicity

Dimethylarsinic acid (DMA) has been used as a herbicide (cacodylic acid) and is the major metabolite formed after exposure to tri- (arsenite) or pentavalent (arsenate) inorganic arsenic (iAs) via ingestion or inhalation in both humans and rodents. Once viewed simply

Arsenic is known to be a human carcinogen as well as one of the most effective drugs for treatment of patients with acute promyelocytic leukemia. The intermediate metabolites of arsenic, monomethylarsonous acid (MMA(III)) and dimethylarsinous acid (DMA(III)), are formed by
