MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay showed the ability of GC7 and DFMO to decrease CRC cell viability (Fig. 1b), an effect that could not be attributed to apoptosis, as shown by the lack of poly (ADP-ribose) polymerase cleavage (Fig. 1c), as well as by the unmodified percentage of apoptotic cells observed by flow cytometry analysis of annexin V and propidium iodide double staining (Fig. 1d). Here, ANXA5 is linked to colorectal carcinoma.
