概括
缺口 papillary 甲状腺癌 (PTCs) 显示出比 lobar PTCs 更具侵略性的分子特征,具有不同的基因表达模式. 这一发现可能解释了在海峡PTC中观察到的攻击性增加.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 基因组学就是基因组学.
背景情况:
- 甲状腺节块与更高的恶性瘤率有关.
- 缺口 papillary 甲状腺癌 (PTCs) 呈现出比 lobar PTCs 更大的攻击性.
研究的目的:
- 为了研究峡谷PTCs的分子概况.
- 使用基因组数据,将峡谷PTC与非峡谷PTC进行比较.
主要方法:
- 使用了癌症基因组图谱 (TCGA) 数据库.
- 分析了472个PTC的临床,突变和基因表达数据,包括19个峡谷PTC.
主要成果:
- 在人口统计学,临床变量或常见突变 (RAS,TERT,瘤抑制剂) 中没有发现显著差异.

02:07Tumor Progression
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...

02:17The 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...
