Analysis of immunohistochemical staining of 5-hmC. Strong nuclear signals of 5-hmC in the NC tissues (low-power field: a, high-power field: b) and decreased nuclear expression in CRC tissues (low-power field: c, high-power field: d). Quantitative analysis of nuclear staining intensity of 5-hmC with H-scores showed a decrease in the CRC tissues, compared to that in the NC tissues (p < 0.01, e); however, no difference was detected between Ob-CRC and nOb-CRC in both NC tissues (p = 0.95, f) and CRC tissues (p = 0.95, g). The H-scores for each case were calculated from the mean scores of three individual sections. **p < 0.01; NS no significant. NC adjacent noncancerous, CRC colorectal cancer, 5-hmC 5-hydroxymethylcytosine, Ob-CRC obese patients with colorectal cancer, nOb-CRC non-obese patients with colorectal cancer.
