概括
个性化慢性疗法可以改善质母细胞瘤治疗. 调整temozolomide (TMZ) 与身体的昼夜时钟,以遗传特征和数学模型为指导,可以提高药物的疗效和患者的治疗结果.
科学领域:
- 在瘤学瘤学.
- 时间生物学 时间生物学
- 计算生物学 计算生物学
背景情况:
- 质母细胞瘤 (GBM) 是一种高度致命的脑瘤,治疗选择有限.
- 标准疗法,如temozolomide (TMZ) 提供最小的益处.
- 时间疗法,定时治疗与昼夜时钟,显示出希望,但缺乏个性化GBM.
研究的目的:
- 调查针对质母细胞瘤 (GBM) 的个性化特莫索洛米德 (TMZ) 慢性治疗.
- 探索昼夜钟基因在TMZ敏感性中的作用.
- 开发一个计算模型来预测最佳治疗时间.
主要方法:
- 使用了GBM体外模型,对时钟基因进行了基因和药理学操纵 (BMAL1,NR1D1,PER2).
- 在一天的不同时间评估TMZ敏感性.
- 开发了一种机械的药理动力学-药理动力学模型,整合了昼夜网络.
主要成果:
- 在GBM中,TMZ敏感性显著依赖于一天中的时间.
- 时钟基因的破坏降低了TMZ的有效性,可能是通过改变的DNA修复.
- 与时钟调节器同时治疗影响了基于细胞时钟表型的TMZ反应.

Combination Therapies and Personalized Medicine
5.8K
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...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
331
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...
