Quantitative determination of 5-hmC with ELISA using DNA isolated from FFPE tissues. Compared to the NC tissue, CRC tissue showed a decrease in 5-hmC as well as H-scores (p < 0.01, a). There was no difference in 5-hmC levels between the nOb-CRC and Ob-CRC groups in NC tissues (p = 0.46, b); however, there was a significant decrease in CRC tissues in the Ob-CRC group (p = 0.03, c). *p < 0.05; **p < 0.01; NS, no significant, FFPE formalin-fixed paraffin-embedded, NC the adjacent noncancerous, CRC colorectal cancer, 5-hmC 5-hydroxymethylcytosine, Ob-CRC obese patients with colorectal cancer, nOb-CRC non-obese patients with colorectal cancer.
