Expression of Met‐enkephalin (MENK) and tumorigenicity or metastasis in colon carcinoma cells. (a) MENK levels in IEC6 rat intestinal cells, IEC6A azoxymethane (AOM)‐induced transformed IEC6 cells, CT26 mouse colon cancer cells, and Colo320 and HT29 human colorectal cancer cells. Tubulin served as a loading control. (b) MENK concentration in cultured medium was compared with tumorigenicity and metastasis of IEC6, IEC6A, and CT26 cells in syngeneic rodent models. *P < 0.0001, **P = 0.0108. Error bar, SD.
