Inhibition by IOA-289 of cell proliferation in gastrointestinal cancer cell lines. Cells were grown in serum free culture medium or in presence of 10% FBS and incubated with increasing IOA-289 concentrations or with DMSO (control cells) for 24, 48 and 72 h. After fixation, proliferation was assessed with the crystal violet staining method. *P < 0.05
