概括
无塑性甲状腺癌 (ATC) 具有独特的瘤微环境 (TME),具有更多的免疫细胞和纤维细胞. 这种侵袭性癌症可以分为两种亚型,其中一种表现出更差的生存率,并提供潜在的治疗点.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 基因组学就是基因组学.
背景情况:
- 无塑性甲状腺癌 (ATC) 预后不佳,治疗选择有限.
- 对ATC的瘤微环境 (TME) 特性还没有很好地了解.
- 了解TME变异对于改善ATC患者的结果至关重要.
研究的目的:
- 为了全面分析ATC的TME.
- 为了识别与ATC预后相关的TME特征.
- 在ATC TME中探索潜在的治疗点.
主要方法:
- 分析了来自1634个甲状腺组织样本的大量RNA转录数据,包括正常,良性,差异化甲状腺癌 (DTC) 和ATC.
- 解卷分析以评估TME的组成和分子特征.
- 在不同类型的甲状腺癌亚型中比较TME概况.
主要成果:
- 与其他甲状腺组织学相比,ATC表现出独特的TME,具有丰富的免疫细胞和纤维细胞,以及稀缺的上皮细胞.
- 确定了两个不同的ATC分子亚型:ATC-免疫纤维细胞 (ATC-IF) 和ATC-上皮-内皮细胞 (ATC-E).
- 亚型ATC-IF显示疾病特异性存活率较差,ERK得分较高,免疫检查点和上皮-介质细胞转变基因表达增加.
结论:
- 甲状腺癌具有独特的TME,与差异化甲状腺癌显著不同.
- 已确定的ATC亚型 (ATC-IF和ATC-E) 具有独特的TME配置文件和预后影响.
- 具有大量免疫细胞和纤维细胞的ATC-IF亚型具有改善患者生存的潜在治疗点.

lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
The Tumor Microenvironment
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...
