Figure 1. Effects of nicotinamide on UVA- and/or UVB- mediated modulations in 8oxoG in melanocytes.
Immunostaining of 8oxoG in melanocytes was performed 1 h post-UV-exposures with or without nicotinamide (50 µM) treatments. Representative images (20x magnification) of DAPI (blue color), 8oxoG staining (red color), and merged are shown for each group of cells. Scale bar = 200 µm. The data shown here represent the experiments done twice in duplicates.
