Figure 2. Plant extracts decreased nuclear and mitochondrial DNA lesions in UVB-irradiated keratinocytes. HNKC were first pre-treated during 3h with AA, PI, PR or MIX (values shown as µg/mL) before irradiation with UVB (60mJ cm^-2). AP sites lesions of nuclear (upper panel) and mtDNA (lower panel) were quantified 24h later and results are shown as the percentage of lesions, compared to untreated UVB-irradiated cells (black column). p values compared data from treated to untreated irradiated HNKC. Data show mean from 3 ± SD from distinct HNKC preparations
