Fig. 7. Tuba RNAi knockdown inhibits invasive behavior of B16 cells. (A) Matrigel invasion assays of B16 cells transfected with the indicated vectors. Error bars represent s.d. (***P<0.005, **P<0.01). (B) Representative images of the PET membranes from the bottom of Matrigel invasion chambers. Cell area was calculated using Metamorph software and corrected for pore area (see Materials and Methods).
