Obtained results
demonstrate that rutin significantly reduced UVA-induced xanthine
and NADPH oxidase activity what was accompanied by changes in ROS generation. Rutin also enhanced antioxidants activity [SOD] and non-enzymatic antioxidant level [GSH, vitamin E and C],
which decreased due to UVA exposure. It was shown that UVA-induced Nrf2 activity has been reduced by rutin. Simultaneously, rutin led to increase in Nrf2 inhibitor Bach2 in UVA irradiated cells.
It was shown that UVA caused significant decrease in linoleic and arachidonic acids levels and in consequence a strong increase in lipid peroxidation products - MDA and 4-HHE level were observed.
Also another lipid mediators – endocannabinoids level was changed during UV irradiation. Thesignificantly reduced level of cytosolic AEA and 2-AG and accompanied higher expression in the level of their receptors CB1, CB2, VR1 and GPR55 were demonstrated. Rutin given after irradiation
prevented the most changes caused by UV irradiation.
Rutin also protect cells against inflammatory
