MF-associated UM cell death is related with the activation of executer caspase-3/7. A Green nuclear staining is generated upon a chemical reaction catalyzed by either active caspases 3 or 7. The images shown represent the endpoint of an experiment done for 72 h following MF treatment at a 40 µM concentration. These images can be observed over imposed with phase contrast in Additional file 5: Fig. S5. B Depicted are the time-course quantifications of the green fluorescence expressed as relative activity with respect to the fluorescence generated by vehicle-treated cells
