pubmed:abstractText |
An invasive variant of Moloney sarcoma virus-transformed MDCK cells (MSV-MDCK-INV), which was isolated by the repeated selection of cells that successfully traversed a Matrigel-coated filter, exhibits increased motile ability and presents an elongated cell shape and numerous pseudopodia. Although stress fibers are present in both MDCK and MSV-MDCK cells, MSV-MDCK-INV cells contain no stress fibers and exhibit a dense concentration of actin at the tips of pseudopodia. Relative to both MDCK and MSV-MDCK cells, the MSV-MDCK-INV cells exhibit increased expression of beta-actin and redistribution of beta-actin to the tips of pseudopodia. These actin concentrations are enriched in both F- and G-actin and, thus, represent dynamic regions of actin cytoskeleton remodeling. The acquisition of invasive properties by epithelial transformants is, therefore, associated with the increased expression of beta-actin and its concentration in actin-rich domains, which may drive pseudopodial extension and facilitate tumor cell invasion.
