From: Potential role of p21 Activated Kinase 1 (PAK1) in the invasion and motility of oral cancer cells
Biological effects of PAK1 knock-down in OSCC cells. a Immunoblot analysis of PAK1 expression in control and PAK1 knock-down SAS cells and its densitometric quantitation. b Phalloidin staining showing actin structures in the SAS cells treated with the control or PAK1 siRNA. c Wound healing assay in the SAS cells treated with the control or PAK1 siRNAs. d Fluorescent images obtained after matrigel invasion assay, showing the cells (stained with Dil C) that have migrated through the matrigel. A quantitative representation of the image data is also illustrated
