Abstract
OBJECTIVE: Nasopharyngeal carcinoma (NPC) is one of the most ordinary head and neck tumors. This study aims to uncover the role of circ-ABCB10 functions in the progression of NPC. PATIENTS AND METHODS: The circ-ABCB10 expression was detected in paired NPC patients' tissue samples and cell lines. The role of circ-ABCB10 in NPC proliferation was identified through proliferation assay, Ethynyl deoxyuridine (EdU) assay and colony formation assay. Next, the role of circ-ABCB10 in NPC metastasis was measured through wound healing assay and transwell assay. Finally, the underlying mechanism was further uncovered through Western blot assay and real-time quantitative polymerase chain reaction (RT-qPCR). RESULTS: It was found that circ-ABCB10 expression was significantly higher in NPC tissues than that in adjacent samples. In addition, cell proliferation, migration and invasion of NPC were promoted through overexpression of circ-ABCB10 in vitro. Results of further experiments revealed that ROCK1 was upregulated via overexpression of circ-ABCB10 in NPC. CONCLUSIONS: This study indicated that circ-ABCB10 promoted NPC cell proliferation and metastasis via upregulating ROCK1 in vitro.
