Figure 4. PDEF expression levels alter cell migration.
The effect of PDEF expression on the migration of colon cancer cells was measured by transwell assay. (A) DLD-1 cells were untreated or infected with Ad-GFP or Ad-PDEF and migration measured by transwell assays. Data is representative of three experiments performed in triplicate. (B) LoVo, CaCo-2, and SW620 cells were infected with Ad-GFP or Ad-PDEF. Cell migration was measured by transwell migration assay. (C) Western blot analysis of PDEF protein expression in HT-29 colon cancer cells and in HT-29 expressing short hairpin RNA (shRNA) PDEF and control vectors. Actin levels provided as a control. (D) Cell migration of HT-29 colon cancer cells and of HT-29 cells expressing PDEF shRNA. Each of the measured differences were statistically significant with a p-value <0.05 by students t-test.
