摘 要: | 目的:研究miRNA-30b纳米粒对甲状腺未分化癌细胞株TA-K细胞的生物学特性的影响。方法转染不同浓度的miRNA-30b纳米粒进入TA-K细胞中,通过流式法检测TA-K细胞凋亡情况,后通过生物信息学预测miR-NA-30b的生物学靶点,并通过RT-PCR及Western Blot方法验证。结果发现转染了miRNA-30b纳米粒后,TA-K细胞的凋亡显著增加,而生物信息学显示miRNA-30b可靶向作用于Survivin,后经RT-PCR及Western blot 法证实Sur-vivin确实是miRNA-30b的生物学靶点。结论 miRNA-30b可以通过作用Survivin促进TA-K细胞的凋亡,这一现象也为将来甲状腺未分化癌的临床治疗提供了新的思路。

Abstract: | Objective To explore the influence of miRNA-30b nanoparticles transaction on biological characteristics of an-aplastic thyroid carcinoma cell line TA-K cells.Methods Different concentrations of miRNA-30b nanoparticles were trans-fected into TA-K cells and apoptosis rate was detected by flow assay .MiRNA-30b biological targets were then predicted through bioinformatics analysis , and validated using RT-PCR and Western Blot methods .Results After miRNA-30b nanoparticles transfection,the apoptosis rate of TA-K cells significantly increased .Bioinformatics showed miRNA-30b could be targeted on Survivin,which was bioinformatically confirmed by RT-PCR and Western blot methods .Conclusion The study indicates that miRNA-30b can promote apoptosis by targeting Survivin in TA-K cells.This phenomenon provides a new approach to anaplastic thyroid carcinoma therapy . |
