Nicotinamide reduced arsenic and UV-induced 8oxoG levels in the epidermal layer of <i>ex vivo</i> human skin at 45 minutes after UV irradiation (a).
<p>Samples were exposed to either 50μM nicotinamide, 2μM sodium arsenite, PBS (control) with or without 2J/cm<sup>2</sup> of UV. The columns represent the mean ±SEM (n = 3). * = p<0.05, ** = p<0.01 one way ANOVA. <b>Staining of 8oxoG 45 minutes following UV radiation, arsenic and nicotinamide exposure in <i>ex-vivo</i> human skin (b)</b>. The blue staining represents DAPI (nuclear staining). The red staining represents 8oxoG staining.</p
