| abstractText | CDK5 and its activator, p35, are expressed in mouse corneal epithelium and can be coimmunoprecipited from corneal epithelial cell lysates. Immunostaining shows CDK5 and p35 in all layers of the corneal epithelium, especially along the basal side of the basal cells. Stable transfection of corneal epithelial cells with CDK5, which increases CDK5 kinase activity by approximately 33%, also increases the number of cells adhering to fibronectin and the strength of adhesion. CDK5 kinase activity seems to be required for this effect, because the kinase inactive mutation, CDK5-T33, either reduces adhesion or has no significant effect, depending on the level of expression. Using an in vitro scrape wound in confluent cultures of stably transfected cells to examine the effect of CDK5 on cell migration, we show that reoccupation of the wound area is significantly decreased by CDK5 and increased by CDK5-T33. These findings indicate that CDK5 may be an important regulator of adhesion and migration of corneal epithelial cells. |
