562. 解码阿尔茨海默病之谜:垃圾DNA中的基因开关
from 知为谁 · host 知为谁
这项由新南威尔士大学开展的前沿研究揭示了“垃圾DNA”中隐藏的遗传开关,这些开关对调节与阿尔茨海默病相关的脑细胞至关重要。科研人员利用CRISPRi技术和单细胞测序手段,在星形胶质细胞中成功鉴定出约150个能够影响基因活性的功能性增强子。由于许多致病性的基因变异存在于非编码区,这一发现为理解神经退行性疾病的分子机制提供了精细的蓝图。此外,该研究产出的高价值数据集正被用于训练人工智能模型,以更精准地预测基因的表达与调控。这项成果不仅填补了人类对98%非编码基因组认识的空白,也为未来实现精准医疗和细胞特异性基因疗法奠定了基础。内容来源:https://www.sciencedaily.com/releases/2025/12/251219093315.htm
