Abstract

Matrine is an alkaloid extracted from the leguminous plant Sophora flavescens. Matrine has clinical effects in the treatment of tumors, including those in lung cancer, nasopharyngeal cancer and liver cancer. However, the effect of matrine on follicular thyroid cancer has not been reported. The aim of the present study was to investigate the effect of matrine on follicular thyroid cancer and its potential mechanism. FTC‑133 follicular thyroid cancer cells were treated with different concentrations of matrine, and an MTT assay showed that matrine inhibited the growth of FTC‑133 cells in a dose‑ and time‑dependent manner with an IC50 value of 154.8 µM. Cell apoptosis was analyzed by flow cytometry and the results showed that matrine effectively induced the apoptosis of FTC‑133 cells. The expression level of microRNA (miR)‑21 was analyzed by reverse transcription‑quantitative PCR (RT‑qPCR) analysis, and the mRNA and protein expression levels of PTEN, Akt and phosphorylated (p)‑Akt were detected by RT‑qPCR analysis and western blotting, respectively. The expression of miR‑21 was significantly downregulated, PTEN was upregulated at the mRNA and protein expression levels, and p‑Akt was downregulated in the FTC‑133 cells. The effects of miR‑21 mimics and miR‑21 inhibitor on the expression of miR‑21, PTEN and Akt in FTC‑133 cells, and the effect of miR‑21 mimics/matrine on the expression of PTEN were also investigated. The results of the present study suggested that matrine inhibited the growth and induced apoptosis of FTC‑133 cells via the miR‑21/PTEN/Akt signaling pathway.
