A total of 141 patients with UC who underwent a proctocolectomy were enrolled in this study. The expression of 8-nitroguanine (8-NG), 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG), and inducible nitric oxide synthase (iNOS) in the rectal mucosa were evaluated using immunohistochemistry (IHC) and assessed relative to the pathogenesis of UC-associated neoplasia. The results suggest that evaluating the expression levels of 8-NG in the rectal mucosa may be a useful biomarker for detecting patients with UC-associated neoplasia., 2011年度~2013年度科学研究費補助金(基盤研究(C))研究成果報告書, 23591960}, title = {潰瘍性大腸炎関連性大腸癌に対する新しい早期診断法有効性の検討と確立に向けた研究}, year = {2014} }
