Endogenous p190A was found in spreading Huh6 hepatoblastoma cells in both dot-like invadopodia (cells plated on glass) and linear invadosomes (cells plated on glass coated with type I collagen fibers) but also in v-Src–induced rosettes in NIH-3T3 cells (Fig. S1A). This evidence concerns the gene ARHGAP35 and hepatoblastoma.
