| pubmed-article:9732295 | pubmed:abstractText | Previously we found that alpha3beta1 integrin-deficient neonatal mice develop micro-blisters at the epidermal-dermal junction. These micro-blisters were associated with poor basement membrane organization. In the present study we have investigated the effect of alpha3beta1-deficiency on other keratinocyte integrins, actin-associated proteins and F-actin organization. We show that the absence of alpha3beta1 results in an increase in stress fiber formation in keratinocytes grown in culture and at the basal face of the basal keratinocytes of alpha3-null epidermis. Moreover, we see a higher concentration of actin-associated proteins such as vinculin, talin, and alpha-actinin at focal contact sites in the alpha3-deficient keratinocytes. These changes in focal contact composition were not due to a change in steady-state levels of these proteins, but rather to reorganization due to alpha3beta1 deficiency. Apart from the loss of alpha3beta1 there is no change in expression of the other integrins expressed by the alpha3-null keratinocytes. However, in functional assays, alpha3beta1 deficiency allows an increase in fibronectin and collagen type IV receptor activities. Thus, our findings provide evidence for a role of alpha3beta1 in regulating stress fiber formation and as a trans-dominant inhibitor of the functions of the other integrins in mouse keratinocytes. These results have potential implications for the regulation of keratinocyte adhesion and migration during wound healing. | lld:pubmed |
