1283-构建iPSC源性神经嵴模型解析恶性神经鞘瘤演进与治疗机会

from 聊聊Sci

这项研究利用人类诱导多能干细胞(iPSC)构建了一个模拟神经纤维瘤病1型(NF1)恶性演变的细胞模型。通过对NF1、CDKN2A和SUZ12基因的序列失活,研究人员成功再现了肿瘤从良性向恶性外周神经鞘瘤(MPNST)转化的过程。实验揭示了PRC2缺失如何导致染色质重组,进而触发从神经胶质向间充质表型的转变。利用这一三维培养平台,研究发现PARP抑制剂与MEK抑制剂(如司美替尼)的联合用药能显著抑制肿瘤生长。这一成果不仅阐明了肿瘤发生的分子机制,还为治疗极具侵袭性的MPNST提供了新的药物靶点和临床策略。References:Uriarte-Arrazola I, Magallón-Lorenz M, Fernández-Rodríguez J, et al.
