Gardenia jasminoides Extract Attenuates the UVB-Induced Expressions of Cytokines in Keratinocytes and Indirectly Inhibits Matrix Metalloproteinase-1 Expression in Human Dermal Fibroblasts

Figure 6

Effects of Gardenia jasminoides extract on caspase-9 and caspase-3 in HaCaT cells exposed to UVB radiation. 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. The cleavage of procaspase-9 and procaspase-3 to their cleaved active forms was analyzed by Western blot. Data are expressed as fold changes (means ± SEs; ). # versus the unirradiated control. * versus the vehicle control irradiated with UVB.
