Abstract

Thyroid cancer is one of the most common malignant tumors, and the mortality rate associated with thyroid cancer has been increasing annually. Curcumin has been reported to exert an antitumor effect on papillary thyroid cancer (PTC), and the identification of additional mechanisms underlying the anticancer effect of curcumin on PTC requires further investigation. The present study aimed to explore the effects of curcumin on the viability, migration and invasion of PTC cells. TPC‑1 cells were incubated with different concentrations of curcumin, and then, cell viability, migration and invasion, and wound healing were examined by CCK‑8, Transwell and wound healing assays, respectively. Subsequently, microRNA (miR)‑301a‑3p mimics, miR‑301a‑3p inhibitors and signal transducer and activator of transcription (STAT)3 overexpression vector were transfected into TPC‑1 cells, and cell viability, migration, and invasion were reassessed in these transfected cells. Matrix metallopeptidase (MMP)‑2, MMP‑9, epithelial‑mesenchymal transition (EMT)‑related markers, and Janus kinase (JAK)/STAT signaling pathway components were assessed by western blot analysis. Curcumin significantly inhibited cell viability, migration and invasion and downregulated MMP‑2, MMP‑9 and EMT marker expression. Additionally, curcumin decreased STAT3 expression by upregulating miR‑301a‑3p expression, and the inhibition of miR‑301a‑3p and the overexpression of STAT3 reversed the effects of curcumin on cell viability, migration and invasion, and MMP‑2, MMP‑9 and EMT marker expression in TPC‑1 cells. Furthermore, curcumin suppressed the JAK/STAT signaling pathway through the miR‑301a‑3p/STAT3 axis. The data of the present study indicated that curcumin could inhibit the viability, migration and invasion of TPC‑1 cells by regulating the miR‑301a‑3p/STAT3 axis. These findings may provide a possible strategy for the clinical treatment of PTC.
