Has_circ_0008583 modulates hepatocellular carcinoma progression through the miR-1301-3p/METTL3 pathway

Has_circ_0008583 is reported to be involved in the progression of hepatocellular carcinoma (HCC), while its biological role in HCC remains unclear. Here, the qRT-PCR was used to detect the expression of has_circ_0008583. The CCK-8 kit was performed to measure cell proliferation. The cell migration and invasion were evaluated by Transwell. A dual-luciferase reporter assay was performed to confirm the target combination between the genes in has_circ_0008583/miR-1301-3p/METTL3 axis. The in vivo role of has_circ_0008583 was verified by murine xenograft assay. Our data showed that hsa_circ_0008583 was upregulated in HCC tissues and cells. Hsa_circ_0008583 overexpression promoted Hep3B cell proliferation, migration and invasion, but hsa_circ_0008583 silencing had an opposing influence. MiR-1301-3p is directly bound to hsa_circ_0008583 and METTL3. MiR-1301-3p overexpression or METTL3 knockdown could partially counteract hsa_circ_0008583 overexpression-mediated influence on HCC cell behaviors. In addition, hsa_circ_0008583 depletion inhibits HCC tumor growth in vivo. In conclusion, hsa_circ_0008583 promotes HCC progression through the miR-1301-3p/METTL3 axis.
