Isorhamnetin protects HaCaT keratinocytes against UVB-induced oxidative macromolecular damage. (A) DNA damage was detected by the comet assay. (B and C) Lipid peroxidation was detected by (B) measurement of 8-isoprostane levels in the conditioned media and (C) detection of lipid hydroperoxides in DPPP-stained cells by fluorescence microscopy. (D) Protein oxidation was assayed by measurement of protein carbonyl levels. *Significantly different from control (p<0.05); #significantly different from UVB-irradiated cells (p<0.05). Combination, isorhamnetin+UVB light.
