Beneficial Regulation of Elastase Activity and Expression of Tissue Inhibitors of Matrixmetalloproteinases, Fibrillin, Transforming Growth Factor-, and Heat Shock Proteins by P. leucotomos in Nonirradiated or Ultraviolet-Radiated Epidermal Keratinocytes
Figure 3
Antagonistic effects of P. leucotomos and UVA radiation on HSP-27 and -70 in epidermal keratinocytes. Nonirradiated (NI), UVA, or UVB radiated keratinocytes were exposed to PL (0, 0.01% or 0.1%) for 24 hours and examined for HSP-27 protein (a) and HSP-70 (b). *, relative to respective controls (0% PL). Δ: , between nonirradiated and UV radiated cells. Error bars represent standard deviation, .
