Preventive role of M89PF on the skin barrier-associated protein Involucrin. Involucrin expression levels in skin explants samples exposed to O3, UV, O3+ UV and/or pretreated topically with M89PF for 24h and analyzed at DAY 1 (A) or DAY 4 (B). Magnification 40X. Scale bar 100 μm. Right panels shown the quantification of relative immunofluorescence staining for Involucrin after different treatments (DAY 1; DAY4). Data are expressed as the mean of the three different subjects ± standard deviation. *p≤0.05 Ctrl vs Pollutant; #p≤0.05 M89PF + Pollutant vs Corresponding pollutant. One-way ANOVA followed by Bonferroni post hoc test.
