ABSTRACT
OBJECTIVE:
Emerging evidence has demonstrated vital regulation of circular RNAs (circRNAs) on tumorigenesis and progression of tumors. Abnormally expressed circRNAs hsa_circ_0005075 (circ_0005075) has been reported in several tumors. In this study, we aimed to explore the expression profiles, prognostic value, and potential function of circ_0005075 in colorectal cancer (CRC) PATIENTS ANDMETHODS:
RT-PCR was used to detect the expression of circ_0005075 in both CRC tissues and cell lines. The associations between circ_0005075 expression and clinicopathological features and clinical prognosis were statistically analyzed. The effects of circ_0005075 on CRC cells were evaluated by Cell Counting Kit-8 (CCK-8), colony formation assays, Flow cytometer, and transwell assays. Western blot was performed to explore whether circ_0005075 modulated the Wnt/ß-catenin pathway.RESULTS:
We observed that circ_0005075 expression was significantly up-regulated in both CRC tissues and cell lines. Then, clinical assays indicated that high circ_0005075 expression was significantly associated with histology/differentiation, depth of invasion, advanced TNM stage, and shorter overall survival and disease-free survival of CRC patients. Cellular studies indicated that circ_0005075 can enhance the proliferation, migration, and invasion capacities of CRC cells, thereby promoting tumor progression. Further mechanistic investigation showed that circ_0005075 displayed its tumor-promotive roles through activating Wnt/ß-catenin pathway.CONCLUSIONS:
Our present data revealed circ_0005075 as a potential molecular marker and target for the prognosis and treatment of CRC patients.
