电压通道辅助子单元α2/delta1 (CACNA2D1) 的高表达与结肠癌预后不佳有关. CACNA2D1通过调节纤维细胞来影响癌症的进展和瘤微环境,这表明它是治疗点.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症 微环境 研究 研究
背景情况:
- 电压通道辅助子单元α 2/delta 1 (CACNA2D1) 被认为是各种癌症中的癌基因.
- CACNA2D1在结肠癌 (CC) 进展中的特定作用及其对瘤微环境的影响在很大程度上仍未被描述.
研究的目的:
- 研究CACNA2D1在结肠癌中的功能作用.
- 确定CACNA2D1对结肠癌微环境的影响,特别是其与纤维细胞的相互作用.
主要方法:
- 在200名结肠癌患者样本上进行免疫组织化学 (IHC).
- 在HCT116和RKO结肠癌细胞系中使用siRNA击败CACNA2D1.
- 细胞增殖,细胞周期,细胞亡和迁移的分析.
- 与结肠癌细胞和CCD-18Co纤维细胞共同培养的实验.
- 微阵列分析用于基因表达造型.
主要成果:
- 高CACNA2D1表达与结肠癌患者的预后不佳相关,并与肌变化相关.
- CACNA2D1的枯竭减少了细胞的增殖和迁移,增加了亚G1阶段的人口,并诱导了细胞亡.
- CACNA2D1通过纤维细胞调节影响癌症的微环境.
- 微阵列分析表明,在CACNA2D1贫乏细胞中,增强了p53信号传递和上皮层-介质细胞过渡通路.
结论:
- CACNA2D1在结肠癌的进展中起着重要作用,并通过纤维细胞调节调节瘤微环境.
- 在结肠癌中,CACNA2D1可能作为疾病进展的潜在生物标志物.
- 在结肠癌治疗中,CACNA2D1是一个有前途的治疗标.

The Tumor Microenvironment
Tumor Progression
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...

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
