Fig. 4. Cells expressing mutant BRG1 show increased levels of some adhesion proteins. Western blots against urokinase receptor (a) and
V and
5 integrins (b) indicate increased levels in each of the three cell lines expressing mutant BRG1. Phosphatidylinositol 3-kinase (PI3K) levels were monitored as a loading control; Flag levels indicate the level of mutant BRG1 protein expressed in each line. The tet-VP16 samples probed for uPAR levels were run on a separate gel and spliced into the figure.
