美登木素抑制鼻咽癌的增殖以及侵袭迁移机制的生物信息学分析

摘要

Objective To investigate the suppressive effects of Maytansine on the proliferation,migration and invasion of nasopharyngeal carcinoma (NPC) cells.Methods MTT assay was employed to study the effect of Maytansine on the viability of 5-8F and SUNE1 cell lines.Wound healing assays and transwell were used to assess the effects of Maytansine on the migration and invasion capacities of NPC cells.Furthermore,an integrated bioinformatics analysis was conducted to clarify the potential mechanisms of Maytansine.Results Time course analysis of Maytansine treated NPC cells indicated significant decrease in cell viability,assessed by MTT.Furthermore,we identified that Maytansine reduced the migration and invasion capacities of NPC cells.Moreover,bioinformatics analysis showed that Maytansine suppressed the proliferation,migration and invasion via the upregulation of CDKN1B,BMP2,HBEGF,SMAD6,ADM,VEGFA,CTGF and IL6 in NPC cells.Conclusion Maytansine plays a significant suppressive role in the proliferation,migration and invasion of NPC cells and may be explored further for its potential therapeutic effects on NPC in humans.%目的:初步验证美登木素对鼻咽癌细胞株增殖以及侵袭迁移的抑制作用,利用公共数据库芯片分析美登木素对细胞株增殖以及侵袭迁移的作用机制.方法:体外实验检测关登木素对鼻咽癌细胞株增殖、侵袭迁移的影响.生物信息学筛选差异表达基因、功能富集分析并进一步筛选出核心基因.分析上调、下调基因的蛋白网络(PPI),并计算蛋白网络以及功能富集分析的核心模块.结果:美登木素显著抑制鼻咽癌细胞的增殖以及侵袭迁移,生物信息学分析得到了美登木素可能影响鼻咽癌的291个上调差异基因,81个下调差异基因.PPI分析表明8个上调的差异表达基因具有显著的生物学意义.结论:美登木素对鼻咽癌细胞株的增殖、侵袭以及迁移具有明显的抑制作用,生物信息学表明CDKN1B、BMP2、HBEGF、SMAD6、ADM、VEGFA、CTGF、IL6等基因的异常表达可能在美登木素对鼻咽癌的侵袭、迁移的抑制中起重要作用.
