Figure 5. POSTN overexpression rescues invasion ability of glioblastoma cells with p73 knock down.

A. Invasion into matrigel of U251 cells that were transfected with siRNA targeting p73, POSTN, both or a nontargeting control is shown. B. As in A, but cells were transfected with siRNA (scr or p73) and plasmids encoding POSTN or empty vector as indicated.
