概括

瘤细胞产生前列腺素E2 (PGE2),在治疗后诱导神经元衰老. 针对这种AEP/PGE2反循环可能会改善质母细胞瘤治疗结果.

科学领域:

神经瘤学神经瘤学
癌症生物学癌症生物学
治疗耐药性的分子机制

背景情况:

瘤-神经元信号传输至关重要,但在放射/化疗的背景下,人们对其了解甚少.
模糊的瘤神经元相互作用阻碍了有效的质母细胞瘤治疗策略.

研究的目的:

阐明在放射/化疗期间神经元与瘤相互作用的机制.
确定改善质母细胞瘤治疗的治疗点.

主要方法:

使用了质母细胞器官 (GBO) 和初级神经元共同培养物.
技术包括代谢学,RNA测序,质谱和体内小鼠模型.
在患者数据 (血清,组织微阵列,TCGA) 中评估了诊断和预后值.

主要成果:

在治疗后诱导神经元衰老的瘤衍生的前列腺素E2 (PGE2).
阿斯巴拉金内酶 (AEP) 分裂了eIF4A1,稳定了PTGES3mRNA并增加了PGE2.
抑制PGE2或AEP减少衰老和延迟瘤进展;高PTGES3与预后不佳相关.

结论:

涉及AEP和PGE2的反循环在放射/化疗期间驱动瘤诱导的神经元衰老.
这一途径代表了增强质母细胞瘤治疗的潜在治疗标.

关键词:

在PGE2的基础上,PGE2 神经元神经元的神经元无线电/化疗治疗.衰老是一种老化.瘤是一个瘤.

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...

Tumor Immunotherapy

Tumor Immunotherapy

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.
