Effect of Lyn on TC71 cell invasion and expression of cadherins. A, parental TC71 cells or TC71 cell clones transfected with control vector or Lyn siRNA-expressing plasmid were assayed for their ability to invade Matrigel. *, P < 0.01, compared with TC/si-control group. B, parental TC71, TC/si-control-transfected, and TC/Lynsi-transfected cells were assayed by Western blot for E-cadherin or cadherin 11. β-Actin was used as the loading control.
