Figure 3. Caspase activity 3/7 assay.

Figure 3

siRNA-transfected H460 cells were harvested after 24 h incubation in the presence or absence of epothilone B and subsequently assayed for apoptosis induction by caspase activity assay. Open bars: control siRNA-transfected cells; light grey solid bars: βII-tubulin knockdown cells; solid black bars: βIII-tubulin knockdown cells; dark grey solid bars: βIVb-tubulin knockdown cells. Data represent means ± SEM of at least three independent experiments. *P<0.05; **P<0.01.
