Figure 4.
H460 (A) and SKLU1 (B) cells treated with activin inhibitor follistatin demonstrated modestly reduced proliferation at 96 hours. (C) H460 cells treated with 10 nM INHBA-targeting siRNA demonstrated reduced cell proliferation at 96 hours relative to mock controls. Repeat transfection 48 hours after initial transfection resulted in further growth inhibition relative to controls.
