概括
带有PAX-FOXO1融合基因的狂肌肉瘤 (RMS) 亚型显示出不同的瘤微环境 (TME). 了解这些TME差异对于开发针对儿童癌症的向疗法至关重要.
科学领域:
- 儿科瘤学 儿科瘤学
- 癌症生物学 癌症生物学
- 免疫学 免疫学 免疫学
背景情况:
- 狂肌肉瘤 (RMS) 是一种儿科癌症,其亚型基于组织学 (ARMS,ERMS) 和融合基因状态 (FP-RMS,FN-RMS) 的亚型.
- PAX-FOXO1融合基因与RMS的预后较差有关.
- 基于融合基因状态的其他儿科癌症中已知瘤微环境 (TME) 的差异,但在RMS中了解甚少.
研究的目的:
- 系统地检查和识别PAX-FOXO1融合阳性 (FP-RMS) 和融合阴性 (FN-RMS) 轮骨髓瘤之间瘤微环境 (TME) 的差异.
- 阐明融合基因状态如何影响TME并驱动RMS恶性病变.
主要方法:
- 对研究RMS中TME的研究进行系统文献综述.
- 在Web of Science,MEDLINE和EMBASE数据库中进行的搜索.
- 包含17项研究,重点是指明融合状态,ECM,斯特罗玛和免疫微环境组件的研究.
主要成果:
- 在ARMS和ERMS之间观察到CD163+巨细胞,矩阵金属蛋白酶 (MMPs) 和肌体血小板衍生生长因子受体 (PDGFRɑ/ß) 的显著差异.
- 在T细胞功能障碍,NECTIN-3表达,PD-1信号传递和干扰素 (IFN) 反应途径中观察到的融合状态差异.
- 只有三项研究在样本数据中明确详细说明了融合状态.
结论:
- 瘤微环境 (TME) 呈现出不同类型的肌肉瘤亚型之间的明显特征,特别是关于融合基因状态.

02:17The Tumor Microenvironment
7.9K
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...

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
