Arsenic trioxide: impact on the growth and differentiation of cancer cells and possible use in cancer therapy
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2013, Vol 67, Issue 0
Abstract
Arsenic trioxide (As2O3) has recently been identified as an effective drug in different types of cancer therapy. It is a useful pharmacological agent in acute promyelocytic leukemia (APL) treatment, especially the form that is resistant to conventional chemotherapy with all-trans retinoic acid (ATRA). What is more, laboratory data suggest that As2O3 is also active when it comes to several solid tumor cell lines. However, the mechanism of action is not fully understood. As2O3 in high doses triggers apoptosis, while in lower concentrations it induces partial differentiation. The As2O3 mechanism of action involves effects on mitochondrial transmembrane potential which lead to apoptosis. It also acts on the activity of JNK kinase, glutathione, caspases, NF-ĸB nuclear factor or pro- and antiapoptotic proteins. This publication presents the current knowledge about the influence of arsenic trioxide in cancer cells.
