概括
在急性淋巴细胞白血病 (ALL) 患者中,DNA-TG (DNA-TG) 可以帮助识别潜在的不坚持6 - 默卡波图 (6-MP) 治疗. 监测DNA-TG提供了一种具有成本效益的方法,以指导进一步的代谢物测试,改善粘附性和预防复发.
科学领域:
- 药物基因组学和治疗药物监测
- 儿科瘤学 儿科瘤学
- 临床药理学 临床药理学
背景情况:
- 坚持6 - 默卡普托普林 (6-MP) /甲甲酸维护疗法对于预防急性淋巴细胞白血病 (ALL) 复发至关重要.
- DNA-TG (DNA-TG) 是6-MP的关键代谢物,其水平与复发风险有关.
- 目前的监测涉及谷氨酸核酸 (TGN) 和甲基化甲氨酸代谢物 (MeMP),预定义的低极限表明潜在的不坚持.
研究的目的:
- 调查使用DNA-TG作为潜在的不坚持6MP/甲甲酸维护疗法的主要指标的可行性.
- 评估DNA-TG水平是否可以有效地标记TGN和MeMP需要进一步测量的情况.
主要方法:
- 对包括DNA-TG,TGN和MeMP在内的6-MP代谢物的分析,在ALLTogether-1 (A2G1) 维护子研究中的368名儿童的3,074个血液样本中.
- 利用线性效应模型来评估DNA-TG,TGN,MeMP和6-MP剂量之间的关联.
- 使用后勤回归来预测基于代谢物水平的治疗中断概率.
主要成果:
- 在6%的样本中,TGN和/或MeMP水平低于既定的不遵守标记限值.
- DNA-TG与TGN,MeMP和处方的6-MP剂量显示出显著的关联 (p < 0.0001).
- 所有TGN和MeMP都低于标记限值的样本中,DNA-TG也低于200 fmol TG/μg DNA.
结论:
- DNA-TG监测可以作为一个具有成本效益的初步步骤,以指导TGN和MeMP的测量.
- 这种方法有助于识别ALL患者对6-MP治疗的潜在不坚持.
- 监测DNA-TG为管理维持治疗和潜在降低复发风险提供了额外的好处.

Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

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...
