PARP inhibition enhances UVB-mediated upregulation of metabolic proteins. (A) Metabolic proteins involved in oxidative phosphorylation were analyzed in total protein lysates. Protein of interest were normalized to the loading control B-actin. Cells were harvested 24 h after UVB. Brightness and contrast were adjusted. (B) Densitometric representation of Figure 8A proteins (n = min. 3). (C) Protein expression involved in oxidative phosphorylation was confirmed by PARP1 knockdown. *; ** and *** indicate statistically significant difference at p < 0.05 and p < 0.01, p < 0.001, respectively. Error bars represent SEM.
