CLIN CANCER RES近期发表了一篇文章,研究化疗激活TGFβ通路的机制以及RER是否可以阻断化疗诱导的TGFβ通路活化从而增强其在妇科肿瘤中的抗肿瘤效果。

作者分析了31例卵巢癌因化疗导致的基因差异表达,寻找改变的主要调节因子。使用免疫组化研究30对宫颈癌磷酸化Smad2表达。使用妇科肿瘤细胞研究化疗对TGFβ信号和功能的影响以及RER对化疗诱导的TGFβ信号的影响。研究结果表明,卵巢癌中化疗导致的转录改变与TGFβ信号活化显着相关。在配对的宫颈癌样本中(化疗前和化疗后),磷酸化Smad2表明化疗可以活化TGFβ信号通路。与TGFβ1相似,化疗药物会刺激Smad2/3磷酸化,细胞迁移以及与上皮间质转化(EMT)和肿瘤干细胞(CSC)相关标志。TGFβ样效果是由于TGFβ1表达和分泌,且可以被TGFβ抑制剂(如TGFβ捕获蛋白RER)消除。更重要的是,肿瘤模型实验表明RER和顺铂联合治疗比单药治疗具有更明显的抑制肿瘤效果。

文章最后认为,化疗药物会刺激TGFβ1产生并增强TGFβ信号,EMT和CSC特性,从而降低化疗敏感性。使用TGFβ抑制剂联合治疗可以缓解化疗的这一副作用从而增强其抗肿瘤效果。
