Lack of PPARβ/δ-Inactivated SGK-1 Is Implicated in Liver Carcinogenesis

Figure 3

Effect of PPARβ/δ on liver cancer cell motility and invasion capability, as assessed by wound healing and Matrigel invasion assays. HepG2 cells stably transfected with pEGFP-PPARβ/δ or the pEGFP vector (control) were subjected to (a) a wound healing assay and (b) a cell migration assay. Representative pictures were taken under an inverted microscope at the indicated time points. (c) Cell motility was quantified by counting the cells that migrated through the Matrigel membrane under a light microscope (×100). The relative cell number ratio was expressed as the . , compared to the control. (d) Representative images of the cell invasion ability of HepG2 cells transfected with pEGFP-PPARβ/δ or the control vector after 48 h. (e) Quantification of cell invasion was estimated by counting the cells that invaded through the Matrigel membrane under a light microscope (×100). The data are expressed as the . , compared to the control.
