Cell viability after incubation with caspase inhibitors prior to transfaction of PTK7 siRNA.

<p>(A) Apoptosis induced by knocking down PTK7 was caspase-dependent. Data are mean±s.d. of three independent experiments. *Student's t-test: P<0.05. (B) Caspase-10 inhibitor totally blocked the apoptosis induced by knock down of PTK7. Data: mean±s.d. of three independent experiments, *Student's t-test: P<0.05.
