1272-膀胱癌浸润前沿的空间转录组特征研究

from 聊聊Sci

这项研究通过空间转录组学技术,利用保留了三维结构的整块经尿道膀胱肿瘤切除术(ERBT)标本,深入分析了非肌层浸润性膀胱癌(NMIBC)的浸润机制。研究人员对比了肿瘤上层与边界区域,发现肿瘤浸润前缘展现出独特的分子特征,特别是与上皮-间质转化(EMT)和细胞运动相关的基因表达显著上调。通过对比不同病理分期的样本,研究界定了一组包含15个基因的特征标签,这些基因在具有高进展风险的肿瘤边界高度富集。外部数据库验证表明,该基因特征的高表达与患者预后不良及较短的生存期密切相关。这一发现不仅揭示了膀胱癌早期浸润的分子演变过程,还为预后评估和精准治疗策略的制定提供了新的生物标志物。该工作强调了维持组织空间架构对于理解肿瘤微环境及开发个性化诊疗方案的重要性。References:Yoshihara K, Urabe F, Umemori M, et al.
