The cytotoxic effect of oxymatrine on basic cellular processes of A549 non-small lung cancer cells.

Oxymatrine is the alkaloid derived from the root of Sophora species. This compound is proven to exhibit anti-viral, anti-asthmatic, anti-fibrotic and anti-inflammatory properties. Additionally, oxymatrine is able to promote cancer cells apoptosis and inhibit their proliferation. The aim of this study was to present the influence of oxymatrine on non-small cell lung cancer cells. The results indicate, that this agent induces dose-dependent cell death mainly through ER stress-induced apoptosis pathway. We also suggest that the oxymatrine reduces the metastatic potential by inhibition of the EMT process, as A549 cells treated with chosen doses of the compound were characterized by a decrease in the expression of the N-cadherin, vimentin and the elevation of E-cadherin level. Moreover, the study broadens the knowledge on so far poorly understood aspect of the influence of oxymatrine on the cytoskeleton structure.
