概括
质母细胞瘤 (GBM) 超越了基因,在复发性瘤中转变为具有WNT/PCP和BRAF激活的神经元状态. 与泰莫索洛米德 (TMZ) 结合的BRAF抑制显示出对抗GBM进展的前景.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 基因组学就是基因组学.
背景情况:
- 质母细胞瘤 (GBM) 的进化是复杂的,不仅涉及遗传变化.
- 了解GBM复发和治疗耐药性对于改善患者的治疗结果至关重要.
研究的目的:
- 使用整合性蛋白质基因组方法研究质母细胞瘤 (GBM) 的进化机制.
- 为了确定驱动GBM复发和治疗耐药性的分子途径.
主要方法:
- 对123对纵向质母细胞瘤的综合性蛋白质基因组分析.
- 瘤样本的蛋白质和质蛋白质分析.
- 对患者衍生异种移植 (PDX) 模型的多原子分析.
主要成果:
- 在复发性GBM中,确定了从诊断时的增殖状态向神经元和突触性通路的转变.
- 在复发瘤中发现了WNT/PCP信号和BRAF激酶的翻译后激活.
- 证明BRAF抑制会损害神经元的过渡和迁移,并且用temozolomide (TMZ) 进行组合治疗可以在PDX模型中延长存活时间.
结论:
- 质母细胞瘤的进化涉及到一个由WNT/PCP和BRAF通路激活的神经元类状态的切换.
- 向BRAF激酶是一个有前途的治疗策略,特别是与temozolomide (TMZ) 结合,以克服质母细胞瘤复发和治疗耐药性.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
