概括
研究人员确定了两种肺腺癌 (LUAD) 亚型,其中一种预后较差. 他们开发了一种与入侵相关的基因分数 (IRGS) 来预测入侵性,并指导LUAD患者的精确治疗.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 生物标志物发现发现
背景情况:
- 肺腺癌 (LUAD) 的侵入性显著影响患者的预后和转移.
- 目前用于评估LUAD瘤侵入性的生物标志物是不够的.
- 了解LUAD分子亚型对于向治疗至关重要.
研究的目的:
- 确定LUAD分子亚型并分析它们的预后和瘤微环境 (TME) 差异.
- 开发和验证一种与入侵相关的基因评分 (IRGS),用于预测LUAD的入侵性和患者的结果.
- 探索IRGS在引导LUAD精准医学中的治疗潜力.
主要方法:
- 无监督的一致聚类,以识别LUAD分子亚型.
- 不同基因表达,WGCNA和LASSO分析来构建IRGS.
- 在体外实验和生物信息工具 (oncoPredict,CMap) 用于验证和药物敏感性预测.
主要成果:
- LUAD被分为两种亚型;C1显示出更差的预后,更高的茎度,更少的免疫透和更高的突变频率.
- 开发的IRGS与侵入性特征,干性,免疫透和生存结果有很强的相关性.

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

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...
