Increased expression of proinflammatory and chemotactic molecules in skins of TR KO mice.

Relative mRNA levels of TNFα, IL-6, S100A8 and S100A9 in wild-type and TR KO mice treated with vehicle, 9-cis-RA or TPA. Values representing expression levels of vehicle-treated wil-type mice were set to 1, and fold induction is represented relative to this basal level.
