Figure 7. AR regulates the invasion in the absence of cystatin C.

A–B). Invasion assay of PC3 cells transfected with control siRNA or against cystatin C and coexpressing AR. The pictures from representative experiment are shown in A and the quantitative absorbances of invading cells (*p<0.05, cystatin C siRNA versus siRNA control, #p<0.05 AR versus CMV, Student T-test) after stating with Cell Stain Solution supplied in the Transwell Invasion assay (Chemicon, Millipore, CA) are shown in B. The data are representative for 3 independent experiments.
