Abstract: Objective To explore the expression of manganese superoxide dismutas (MnSOD) in colorectal carcinoma and its relationship with the clinicopathological findings. Methods The expressions of MnSOD in colorectal carcinoma, adenoma, and adjacent corresponding intestinal mucosal tissues were detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR). The relationship between MnSOD expression level in colorectal adenoma and clinical parameters was analyzed. Results The expression of MnSOD was negative in adjacent corresponding colorectal tissues. The positive expression rate of MnSOD was 44%(11/25)in colorectal adenoma and 76%(19/25)in colorectal carcinoma (P0.05). Conlusion The expression of MnSOD may be associated with the carcinogenesis and progression of colorectalcarcinoma, and therefore may be used as a new biomarker."
