title: Cadherin 11, a miR-675 target, induces N-cadherin expression and epithelial-mesenchymal transition in melasma.
abstract: Cadherin 11 (CDH11) was identified as a target of miR-675 by using a luciferase reporter assay. CDH11 expression and miR-675 expression were inversely correlated. CDH11 expression was not detected in melanocytes, but CDH11 expression in fibroblasts and keratinocytes positively influenced melanogenesis via the canonical Wnt and AKT activation pathways in cocultured melanocytes. CDH11 in fibroblasts or keratinocytes induced N-cadherin and Twist1 expression, while decreasing E-cadherin expression. This suggests a role for CDH11 in epithelial-mesenchymal transition. CDH11 in fibroblasts also induced the migration of cocultured melanocytes. N-cadherin knockdown abolished the tyrosinase expression that was induced in CDH11-overexpressing fibroblasts. Collectively, our data indicate that CDH11 in fibroblasts and keratinocytes is a target of miR-675, and could be involved in melanogenesis through the induction of N-cadherin during epithelial-mesenchymal transition.
