This study defines the in vitro phenomenon of ciliated bovine bronchial epithelial cell (BBEC) detachment from the basal epithelium and regulation of cilia motility mediated through protein kinase C epsilon (PKCε). The authors determined the time course of activation and downregulation of PKCε by the known PKC activator phorbol 12-myristate 13-acetate (PMA) and demonstrate that chemical inhibition of PKC by calphostin C or the novel PKC isoform inhibitor Ro 31-8220 induced striking detachment of ciliated BBECs from the basal cell monolayer within 1 hour, independent of apoptosis or necrotic cell death. The results of this study support a possible novel PKCε-mediated signaling pathway through which ciliated cell attachment is maintained.
