Abstract

Dysregulated microRNA‑329 (miR‑329) serves an important role in the progression of certain types of tumor. However, the exact function and mechanisms of miR‑329 in papillary thyroid cancer (PTC) remain unknown. The present study investigated the function and mechanisms of miR‑329 in regulating PTC cell progression. The results revealed that the expression of miR‑329 was significantly downregulated in PTC tissues and cell lines compared with adjacent normal tissues and a human immortalized follicular cell line. miR‑329 mimics notably decreased PTC cell proliferation, colony formation and WNT1 expression in vitro, as well as suppressing PTC tumor growth in vivo. In addition, luciferase assays determined that miR‑329 was able to directly bind with the 3'untranslated region of WNT1. Furthermore, short interfering RNA‑WNT1‑induced downregulation of WNT1, which demonstrated similar effects to miR‑329 overexpression. WNT1 overexpression rescued the tumor suppressive effects of miR‑329 in PTC cells. The present study provided new insights into the role of miR‑329 in PTC progression and suggests the potential application of miR‑329 as a therapy for PTC.
