概括
介素-8 (IL-8) 水平与早期结直肠癌 (CRC) 阶段相关,而IL-17A和IL-33则表明在晚期的CRC中免疫抑制. 这些细胞因子可以作为CRC进展的生物标志物.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 分子生物学分子生物学
背景情况:
- 结肠直肠癌 (CRC) 的进展受到炎症途径和细胞因子信号传递的显著影响.
- 了解特定的互白蛋白在CRC病变发生中的作用,对于开发向疗法至关重要.
研究的目的:
- 在结肠癌患者中检查interleukin-8 (IL-8),interleukin-17A (IL-17A) 和interleukin-33 (IL-33) 的血清表达水平.
- 分析这些介质蛋白与瘤等级和CRC的入侵深度的关联.
- 在CRC的背景下探索IL-8,IL-17A和IL-33之间的相互关系.
主要方法:
- 42名结肠癌患者的血清样本使用ELISA测试进行了分析.
- 患者根据瘤分化 (G1-G3) 和入侵深度进行了分层.
- 用多重回归分析来评估细胞因子相关性和预测模型.
主要成果:
- 在分化良好的瘤和下/血清侵袭中,IL-8水平升高,这表明在早期CRC和血管生成中发挥了作用.
- 随着瘤脱差和侵袭的增加,IL-17A和IL-33水平下降,这表明晚期的免疫抑制.
- 在IL-8和IL-17A之间观察到显著的非线性关系;IL-33与其他白细胞间蛋白没有直接相关性. 一个组合模型解释了超过70%的IL-17A变异性.
结论:
- 血清IL-8,IL-17A和IL-33水平表现出与CRC进展和分化相关的独特模式.
- 这些介质蛋白显示出作为CRC患者分层的预后生物标志物的潜力.
- 这些细胞因子的交互作用突显了它们作为个性化CRC管理的治疗点的潜力.

02:17The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

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...
