甲状腺癌时,神素-1-酸盐受体1 (S1PR1) 的水平升高,促进瘤生长. 抗癌化合物奎尔素有效降低S1PR1水平,这表明了新的治疗点.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 细胞生物学 细胞生物学
背景情况:
- 氨酸-1-酸盐受体1 (S1PR1) 是一种与G蛋白结合的受体,涉及各种癌症.
- 在甲状腺癌中S1PR1的作用仍然在很大程度上未被研究,尽管有普遍的原始起源共识.
研究的目的:
- 研究S1PR1在甲状腺癌进展中的生物活性和作用.
- 探索针对甲状腺癌中S1PR1的潜在治疗策略.
主要方法:
- 对甲状腺癌组织中的S1PR1蛋白水平与正常组织的定量分析.
- 使用S1PR1-GFP结构和斯芬戈-1-酸盐刺激的细胞局部化研究.
- 在通过CRISPR/Cas9.9生成的S1PR1淘汰甲状腺癌细胞中进行功能测试 (殖民地形成,迁移,入侵).
- 对下游信号通路 (STAT3,ERK1/2,AKT) 和细胞粘附蛋白表达的分析.
- 查抗癌化合物对S1PR1表达的作用,重点关注氨酸.
主要成果:
- 与相邻的正常组织相比,甲状腺癌组织中的S1PR1蛋白水平显著更高.
- S1PR1表现出细胞膜局部化,在刺激时发生细胞内转移.
- S1PR1淘汰细胞显示殖民地形成,迁移和入侵显著减少.
- 在S1PR1淘汰赛细胞中观察到抑制STAT3,ERK1/2和AKT激酶活性以及降低细胞粘附蛋白表达.
- 奎尔丁治疗显著降低了甲状腺癌细胞中的S1PR1蛋白水平.
结论:
- S1PR1蛋白表达与甲状腺癌的进展具有积极的相关性,类似于其他癌症类型.
- 向S1PR1可能代表甲状腺癌的可行的治疗策略.
- 奎尔丁显示出作为S1PR1阳性甲状腺癌细胞的抗癌剂的潜力.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
