Fig. 2: Expression levels of RAGE and related inflammation signals in GO-AGE- and UVB-treated HaCaT human keratinocytes either treated with ULE or FLE.

A RAGE; (B) COX-2; (C) IL-1β; (D) MAPKs pathway proteins (p38, ERK, and JNK); (E) NF-κB and IκB-α protein levels. #p < 0.05, ##p < 0.01, and ###p < 0.001 vs. Control (untreated) group; *p < 0.05, **p < 0.01, and ***p < 0.001 vs. GO-AGEs/UVB-treated group. Results are expressed as the mean ± SEM (n = 3).
