乳腺上皮细胞的代谢特点以及信号通路研究癌症转移,该研究或将有助于开发具有细胞特异性的抗癌干预措施。相关研究结果发表在国际学术期刊Plos Computational Biology上。
 
由于大部分乳腺癌都起源于乳腺上皮细胞,因此为了深入挖掘乳腺癌转移的机制,科学家们构建了一种数学模型,分析乳腺上皮细胞的代谢特点。这种模型专门用于研究上皮间充质转化过程,该过程是癌症发展和转移过程中一个重要事件。
 
在上皮间充质转化过程中,一些信号通路的改变会影响代谢过程,其中一个关键通路变化就是在哺乳动物细胞中负责调节生长,存活,增殖和分化的EGFR信号途径发生的变化。EGFR信号经常影响肿瘤细胞的代谢速率,控制癌症进展,因此该信号途径发生紊乱是肿瘤转移的一个标志。
 
研究人员开发的计算模型能够对EGFR级联信号进行分析,在体外培养的人类乳腺上皮细胞模型中研究EGFR信号途径与上皮间充质转化之间的对话。研究人员利用该模型获得了一系列可能参与EMT的信号途径和分子。
 
这些通路和分子的发现或可帮助深入理解EMT和癌症转移过程中暗藏的分子机制,这项研究还表明了如何对EGFR信号途径中的基因进行转录组分析帮助预测癌细胞生长和EMT的代谢节点,从而为开发细胞特异性的抗癌干预措施提供重要信息。
