Gardenia jasminoides Extract Attenuates the UVB-Induced Expressions of Cytokines in Keratinocytes and Indirectly Inhibits Matrix Metalloproteinase-1 Expression in Human Dermal Fibroblasts
Effects of Gardenia jasminoides extract on UVB-induced lipid peroxidation in HaCaT cells. In (a), HaCaT cells were irradiated with 5~15 mJ cm−2 UVB. In (b), cells were irradiated with 10 mJ cm−2 UVB in the absence or presence of Gardenia jasminoides extract (10, 30, or 100 μg mL−1) and then incubated for 24 h. Lipid peroxidation was determined by quantifying TBARS. Data are expressed as fold changes (means ± SEs; ). Control value was 0.33 nmol TBARS per mg protein. # versus the unirradiated control. * versus the vehicle control irradiated with UVB.
