Effect of SHM on the activation of NF-κB and the reduction of Nrf2/HO-1 in UVB-exposed human keratinocytes. (a) NF-κB-related protein expression levels in SHM-pretreated and UVB-exposed human keratinocytes. (c) Nrf2/HO-1-related protein expression levels in SHM-pretreated and UVB-exposed human keratinocytes. (b,d) The density ratio of protein expression was analyzed via Image J software each in comparison to β-actin or Lamin B. Values are expressed as means ± SE of triplicate determinants (n = 3). a–eBars with different letters for each molecule are significantly different (P < 0.01).
