A: Effect of DHCB on distribution of F-actin and tubulin. Hke-3 cells were left untreated (CTRL) or were left untreated or were treated with DHCB (10 mM) for 4 or 12 hours. Immunofluorescence was performed with antibodies specific for tubulin (green) or by staining with phalloidin for F-actin (red). B: Inhibition of S phase and induction of G0/G1 and G2/M arrest in cucurbitacin treated cells. HCT116 and Hke-3 cells were left untreated or were treated with 12 µM or 25 µM DHCB for 12 hours and the cell cycle profile was determined by PI staining.
