摘要

Purpose: Colorectal cancer is known as the most common gastrointestinal cancers. As the age increases, the risk for this cancer also increases, so the only way to improve and hope for life in these patients is early diagnosis of the disease. So far, numerous molecular studies have been carried out on microRNAs in colorectal cancer. In addition, since some of them can be identified as cancer biomarkers. Therefore, in this study we have investigated the expression level of Mir-30d and Mir-181a as cancer biomarkers. Method: The changes of Mir-30d and Mir-181a expression levels in 60 colorectal tumor tissues and 60 adjacent tumor tissues, after RNA extraction and cDNA synthesis were surveyed using the Real Time-PCR method. Results: The results have reported a considerable reduction in the expression level of Mir-30d in tumor tissues, as well as a significant increase in the expression level of Mir-181a tumor expression in tumor tissues (P<0.05). In addition, the correlation between Mir-30d and Mir181a showed that there was a significant difference between the level of expression of mir-30d with age and TNM stage of CRC (P 0.05).
