    Abstract:
    Colorectal cancer (CRC) is one of the most common malignant tumors in the world. Cases of colon cancer have experienced dramatic growth for the past few decades in China, while the rate of rectal cancer descends 3% every year in the West. The purpose of this study is to reveal the potential impact of miR-21-5p on the occurrence process of CRC and its connection with a close homolog of L1 (CHL1). In this study, the expression level of the miR-151-3p was found to be significantly higher in colon adenocarcinoma tissue compared with adjacent normal tissues, while the CHL1 was lower in colon adenocarcinoma tissues. The expression of miR-151-3p was inversely correlated with the expression of CHL-1, as it was confirmed with correlation analysis. miR-151-3p deregulates the expression of CHL1. CHL1 overexpression can restrain the proliferation and invasion of CRC. Tumorigenesis experiments showed that the tumor growth rate of CHL1-OV was significantly reduced in mice, and its effect could be reversed by miR-151-3p mimics. Taken together, our study may provide new insights into the potential mechanisms of progression of CRC, and may provide a theory for targeted drug therapy.
