The aim of this study is to confirm the toxic effect of phenylethyl isothiocyanate (PEITC) on porcine kidney cells (PK-15) and explore the effect of oxidative damage mediated by reactive oxygen species (ROS) induced by PEITC in PK-15 cells. Porcine kidney cell line (PK-15) was treated with PEITC (2, 5, and 10 µM) for 24 hours, and the oxidative damage mediated by PEITC through ROS was investigated. The survival rate of PK-15 cells decreased in a dose-dependent manner after the treatment of PEITC in a dose-dependent manner. A high concentration of PEITC (10 µM) can change cell morphology, increase the content of malondialdehyde, ROS, and lactate dehydrogenase, and decrease the activity of SOD, CAT, GSH-PX, and GSH. PEITC has a toxic effect on PK-15 cells by inducing oxidative stress in PK-15 cells through the generation of ROS.
Keywords: PK-15 cells; active oxygen; oxidative stress; phenylethyl isothiocyanate.
