Figure 3. Progranulin targeting modulates invasion and anchorage-independent growth of UMUC-3 urothelial cancer cells.
(A) Parental (P), shScr-transfected (Scr) control and Progranulin-depleted (shPGRN) UMUC-3 cells were assessed for invasive ability through Matrigel-coated transwells as described in Materials and Methods. Data are the average of three independent experiments ± SD. ***P < 0.001. Recombinant human progranulin was supplemented at 80 nM. (B) Anchorage-independent growth was measured by colony formation in soft-agar as previously described [18, 19, 49]. Colonies > 150 μM were counted. The experiment is the average of three independent experiments run in duplicates ± SD. ***P < 0.001.
