Abstract:
:In mammalian epidermis, alpha6beta4 integrin is expressed exclusively on the basal layer localized to the hemidesmosomes, where it interacts extracellularly with the laminin-5 ligand. During differentiation, loss of alpha6beta4 is associated with keratinocyte detachment from the basement membrane and upward migration. The protein kinase C (PKC) family of isoforms participates in regulation of integrin function and is linked to skin differentiation. Exposure of primary murine keratinocytes to PKC activators specifically downregulates alpha6beta4 expression. Utilizing recombinant adenoviruses, we selectively overexpressed skin PKC isoforms in primary keratinocytes. PKCdelta and PKCzeta induced downregulation of alpha6beta4 protein expression, leading to reduced keratinocyte attachment to laminin-5 and enhanced gradual detachment from the underlying matrix. In contrast, PKCalpha upregulated alpha6beta4 protein expression, leading to increased keratinocyte attachment to laminin-5 and to the underlying matrix. Altogether, these results suggest distinct roles for specific PKC isoforms in alpha6beta4 functional regulation during the early stages of skin differentiation.
