Retinoids have been shown to modulate the expression of proteins involved in epidermal differentiation. To examine this effect in an in vitro skin model, we evaluated the effect of retinoic acid on the expression of two cell envelope proteins, loricrin and involucrin, and an early marker of epidermal differentiation, keratin 1, in a reconstituted human skin equivalent cultured at the liquid-air interface. Retinoic acid, a known inhibitor of keratinization in monolayer and raft cultures, was evaluated for its ability to alter the expression and distribution of these markers of epidermal differentiation. Retinoic acid (10(-6) M) suppressed loricrin expression in skin cultures as determined by both protein and mRNA analysis. In contrast, no inhibition of involucrin or K1 expression was observed at the protein level at the same retinoic acid concentration. However, some suppression of K1 mRNA transcription was observed in retinoic acid-treated cultures. These results demonstrate that in differentiating cultures of reconstituted human skin, loricrin expression is markedly inhibited by retinoids, K1 less so, and involucrin not at all.
