Protective Effect of Fat Extract on UVB-Induced Photoaging In Vitro and In Vivo

Figure 7

FE reduced ROS-induced cell apoptosis and promoted the expression of GPX-1 and COL-1 in mice. (a) Fluorescence microscopy images and (b) quantification (%) of apoptotic cells following labeling with a TUNEL staining kit. Scale bar: 100 μm. (c, d) Western blotting analysis of GPX-1, catalase, SOD-2, and SOD-1 in mice after FE treatment for 8 weeks. Representative results from three independent experiments are presented. The density values are expressed in arbitrary units. (e, f) Western blotting analysis of COL-1 in mice after FE treatment for 8 weeks. Representative results from three independent experiments are presented. The density values are expressed in arbitrary units ().
