(A) Cell invasion was inhibited by Ad-PTEN in MeWo cells. Mock, Ad-Luc, or Ad-PTEN treated MeWo cells were used. The number of invading cells is indicated on the y axis. Error bars indicate the standard deviation. (B) Cell-surface E-cadherin levels are increased by Ad-PTEN transduction in MeWo cells. Cells were mock, Ad-Luc, or Ad-PTEN treated (2500 or 5000 vp/cell), harvested, and subjected to E-cadherin surface labeling and analyzed by FACS. Error bars indicate the standard deviation.
