Figure 2. Time dependent levels of mRNA encoding BER proteins in NMR and mouse cells after UVC-light irradiation. The data are the mean of three independent experiments made in triplicates ±SD. For each gene the level of its expression in UVC-irradiated cells was normalized to that of non-irradiated cells. Three housekeeping genes: Tubb, Actb and Gapdh were used as a reference.
