Figure 4

Inhibitory effect of α-T and α-T3 on the production of ChOOHs in UV-A-irradiated fibroblasts. Cells were irradiated with UV-A light (800 μW) for 2 h in the presence of hematoporphyrin (1 μM). After irradiation, lipids were extracted and subjected to TLC blotting and gas chromatography–mass spectrometry analyses. White bars, no irradiation; black bars, irradiation with UV-A; light-gray bars, irradiation with UV-A after treatment with α-T (5 μM) for 24 h; dark-gray bars, irradiation with UV-A after treatment with α-T3 (0.5 μM) for 24 h. Values are the means ± S.D. (n = 4). Asterisks indicate significant difference between the non-treatment group with irradiation (black bars) and α-T/α-T3-treated group.
