Inducing caveolin-1 (Cav-1) overexpression in human colorectal cancer SW480 cells. (A) Transfection of SW480 cells was induced using Cav-1-pcDNA (SW480/Cav-1 cells) or pcDNA3.1 (SW480/pcDNA3.1 cells, i.e., controls) plasmid, and transfected cells were selected by G418. The Cav-1 overexpression was confirmed by cell lysates immunoblotting. (B) The ratio of Cav-1 signal to β-actin. ** p<0.01 versus SW480/Cav-1 cells.
