HO-1 expression intensity in CRC and subcategories of clinicopathological characteristics. HO-1 expression intensity was evaluated as mean optical density by using NIS-Elements Br 3.0 image analysis system. HO-1 expression was compared between CRC and normal colon tissues (a), between well differentiated tumors and moderately/poorly differentiated tumors (b), between CRC of different TNM stages (c) and between tumors with and without lymph node metastasis (d). Values are means ± SD; **P < 0.01, ***P < 0.001 between each compared groups (student’s t-test).
