概括
一个新的多omics机器学习模型预测清细胞细胞癌 (ccRCC) 患者对免疫检查点阻塞 (ICB) 治疗的反应. 这种基于炎症和免疫特征 (TI) 的模型为指导精确的ccRCC免疫疗法提供了卓越的预测准确性.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 生物信息学是一种生物信息学.
背景情况:
- 免疫检查点阻塞 (ICB) 治疗,包括PD-1/PD-L1抑制剂,改善了清细胞细胞癌 (ccRCC) 患者的生存率.
- 然而,只有少数ccRCC患者受益于当前的ICB策略,这凸显了需要更好的预测生物标志物.
研究的目的:
- 开发和验证一个多omics机器学习 (ML) 模型来预测ccRCC对ICB治疗的反应和生存.
- 在ccRCC中识别与ICB治疗结果相关的关键炎症和免疫特征 (TI).
主要方法:
- 收集和分析了来自1900多名ccRCC患者的RNA-seq和单细胞RNA-seq (scRNA-seq) 数据.
- 开发了一种TI-ML模型,整合了基因组和转录组资料,以预测ICB反应.
- 验证了该模型在1000多名用ICB治疗的ccRCC患者中的预测能力,并将其与单个生物标志物和现有模型进行比较.
主要成果:
- 鉴定了716个与ICB结果显著相关的炎症相关基因,富含淋巴细胞激活通路.
- 与单个生物标志物 (例如PD-L1,TMB) 和现有模型相比,TI-ML模型显示出优异的预测性能 (AUC > 0.997).
- ccRCC患者被分为两种亚型,根据已识别的特征,具有不同的治疗反应和预后.
结论:
- 开发的TI-ML模型有效地预测了CCRCC患者使用多omics炎症和免疫特征的ICB治疗反应和生存率.
- 该模型在多个独立队列中表现出高度的概括能力,为ccRCC中精确的免疫治疗指导提供了一种新的方法.
- 这种方法有可能显著改善患者选择ICB治疗的可能性,从而导致更好的临床结果.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
4.5K
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Benefits of Self-Esteem
203
Self-esteem—an individual's overall evaluation of their worth—plays a complex role in psychological functioning and well-being. It is often associated with many positive traits, such as confidence, optimism, and perseverance. Individuals with high self-esteem typically experience better sleep, manage peer pressure more effectively, and report greater life satisfaction. Conversely, low self-esteem has been consistently linked with increased risks of depression, anxiety, and poor...

Tumor Immunotherapy
2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Renal Regulation of Acid-Base Balance
1.8K
Metabolic reactions in the body produce nonvolatile acids, such as sulfuric acid, which generate an acid load of approximately 1 mEq of H+ per kilogram of body weight daily. Excreting H+ in the urine is essential to balance this acid load.
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
However, the intercalated cells in...

Body:Bioavailability is a critical pharmacological concept that measures the extent and rate at which an active drug ingredient or therapeutic moiety enters the systemic circulation, remaining unchanged. It's a pivotal factor in determining a drug's efficacy and safety.The Biopharmaceutics Classification System (BCS) plays an essential role in drug development by categorizing drugs into four classes based on their solubility and permeability. This classification aids in understanding drug...
