Objective:To identify the differentially expressed microRNAs(miRNAs) in human colorectal cancer tissues and to make further study on the function of miRNA in pathogenesis and development mechanism of colorectal cancer. Methods:Total RNA was extracted from 10 samples fresh colorectal cancer tissues and normal adjacent tissues and the differentially expressed miRNAs were detected by miRNA array. Real-time PCR was applied to verify the reliability of miRNA array results. Results:miRNA array results showed that 32 miRNAs were up-regulated more than 2.3 folds and 10 miRNAs were down-regulated more than 2 folds in colorectal cancer tissues compared with those in normal adjacent colorectal tissues. And the real-time PCR results were in accordance with the miRNA array results. Conclusion:The miRNA differential expression profile of colorectal cancer is obtained,which might relate with the pathogenesis and development of colorectal cancer.
