Circular RNA takes a crucial part in carcinogenesis. Circ_0058063 has been found to act as an oncogene in esophageal cancer and bladder cancer, but its role in thyroid cancer (TC) is still under investigation. Therefore, we carried out a study to understand its role in TC and its association with miR-330-3p. The circ_0058063 and miR-330-3p in TC tissues and cells were quantified by quantitative reverse transcription PCR, and cell counting kit-8 and scratch adhesion test were conducted for evaluation of cell proliferation and migration. In addition, a dual luciferase reporter assay and RNA immu...
