Effects of moxibustion on colon tumorigenesis in kdm4d−/− CAC mice. A Schematic protocol for the experiments. B Macroscopic observation of the colons of the mice in each group; the formation of colonic tumors is indicated by white arrows. C Comparison of colon length. D-G Comparison of tumor number, tumor load, mean tumor diameter and maximum tumor diameter. H HE staining of the colons of the mice in each group (scale bars, 200 μm). n = 6, compared with the KO-NC group, **P<0.01
