Effects of enzyme-treated caviar (CV) on mRNA expression of TNF-α (A), IL-1β (B), and IL-6 (C) and expression of IkB-α and p65 phosphorylation ((D), band image; (E), quantification of p-IkB-α/total IkB-α; (F), quantification of p-p65/total p65) in the dorsal skin of UVB irradiation-induced photoaging in mice. Normal control (NC, −UVB), control (C, +UVB), L-ascorbic acid (positive control, PC; +UVB with dietary supplementation of L-ascorbic acid at 100 mg/kg/body weight [bw]), CV20 (+UVB with dietary supplementation of CV at 20 mg/kg/bw), CV50 (+UVB with dietary supplementation of CV at 50 mg/kg/bw), and CV100 (+UVB with dietary supplementation of CV at 100 mg/kg/bw). Values are presented as mean ± SD. Different letters (a > b > c > d > e) indicate a significant difference at p < 0.05 by Duncan’s multiple range test.
