背景情况:
- 早期T细胞前体急性淋巴细胞白血病 (ETP-ALL) 起源于多能原始细胞.
- ETP-ALL白血病爆发可以表现出模两可的表型,使诊断复杂化,特别是在复发时.
- 了解复发特征对于优化儿科ETP-ALL治疗策略至关重要.
研究的目的:
- 为了调查复发儿科ETP-ALL的免疫表型变化.
- 分析复发性ETP-ALL的遗传特征和分类挑战.
- 为改善ETP-ALL复发的诊断和治疗决策提供见解.
主要方法:

- 使用了传统的免疫类型,胆型,FISH和下一代测序 (TCR谱,RT-PCR,RNA-seq).
- 对比了儿科ETP-ALL患者的初始诊断和复发样本.
主要成果:
- 在534例T细胞ALL病例中,有60例是ETP-ALL;10例 (16.7%) 复发.

Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
