To clarify the expression pattern of miRNA-875-3p in CRC and its potential regulatory effect on the progression of CRC.MiRNA-875-3p level in 56 matched CRC tissues and adjacent normal tissues were determined. The correlation between the miRNA-875-3p level and pathological indexes of CRC patients was analyzed. Prognostic potential of miRNA-875-3p in CRC patients was assessed by introducing the Kaplan-Meier curves. Influences of miRNA-875-3p on viability, migration, and wound closure were assessed through a series of functional experiments. The interaction between miRNA-875-3p and PLK1 in regulating the progression of CRC was finally uncovered by Dual-Luciferase reporter gene and rescue experiments.MiRNA-875-3p was downregulated in CRC tissues and cell lines. CRC patients with low level of miRNA-875-3p suffered a higher rate of distant metastasis and worse prognosis. Overexpression of miRNA-875-3p attenuated proliferative and migratory capacities of SW480 and HT29 cells. PLK1 was confirmed to be the target gene of miRNA-875-3p. PLK1 was upregulated in CRC tissues and cell lines, which was negatively regulated by miRNA-875-3p. MiRNA-875-3p alleviated the malignant progression of CRC via negatively regulating PLK1.MiRNA-875-3p is downregulated in CRC, which is closely related to distant metastasis and poor prognosis of CRC patients. MiRNA-875-3p alleviates the progression of CRC through targeting and downregulating PLK1. |
