Figure 1From: The interaction of celecoxib with MDR transporters enhances the activity of mitomycin C in a bladder cancer cell lineProtein expression levels of COX-2, P-gp, MRP1 and BCRP in UMUC3, UMUC-3-CX, 5637, 5637si-CX, TCCsup, and J82, as determined by western blot. Cell lysates were obtained from exponentially growing cells and subjected to immunoblotting with appropriate antibodies. Immunoblotting with an antibody to β-actin was used to ensure equal loading of proteins in each lane (bottom).Back to article page
