UVB irradiation on liver TNFα, IL-1β, and IL-6 expression in hairless mice.

<p>The levels of TNFα (A), IL-1β (B), and IL-6 (C) mRNA in the liver were determined by real-time PCR and expressed relative to the level of β-actin mRNA. The level of IL-6 protein in the liver was measured by ELISA (D). Data represent the mean ±SE (n = 6). ^#<i>p</i><0.05 indicates values that are significantly different from the UVB (−) group. UVB (−), non-UVB-irradiated mice; UVB (+), UVB-irradiated mice.
