638. 肠道硬化与早发性结肠癌风险研究
from 知为谁 · host 知为谁
这项由德克萨斯大学西南医学中心主导的研究揭示了结直肠癌年轻化的潜在生物学机制。研究发现,长期慢性炎症会导致肠道组织产生疤痕并显著变硬,这种物理环境的改变会加速癌细胞的生长。通过对比不同年龄段患者的样本,科学家注意到早发型患者的胶原蛋白密度更高且排列更紧密,这种机械力变化会转化为生化信号刺激肿瘤。这一发现不仅解释了为何年轻人患病率激增,也为未来的早期筛查和阻断癌症扩散的药物研发提供了新方向。该研究强调了组织硬度在癌症病理学中的关键作用,打破了以往仅关注遗传或环境因素的局限。内容来源:https://scitechdaily.com/stiffer-colon-linked-to-increased-risk-of-early-onset-cancer/
