Amelioration of B16F10 melanoma cells induced oxidative stress in DBA/2 mice by pentoxifylline.
The constantly produced small amounts of reactive oxygen species (ROS) are reduced by anti-oxidant enzymes and cellular scavengers. The oxidative stress developed by defect in ROS clearance can result in cell injury and may lead to carcinogenesis. Pentoxifylline is a methylxanthine derivative with rheologic and membrane modifier property. We have examined whether Pentoxifylline (PTX) ameliorates oxidative stress produced in subcutaneously injected mice with B16F10 melanoma cells. Treatment of mice with PTX significantly reduced oxidative stress and attenuated the altered changes of reduced glutathione and lipid peroxides. Our findings provide an experimental basis for using PTX to attenuate oxidative stress induced by B16F10 melanoma cells in liver and lung of DBA/2 mice.
