概括

在儿科急性髓性白血病 (AML) 中,线性基因被上调. 过度表达FUNDC1与较差的无复发生存率有关,这表明小儿AML的潜在治疗点.

科学领域:

生物化学生物化学
分子生物学分子生物学
在瘤学瘤学.

背景情况:

线粒体,一种选择性形式的自,对于线粒体质量控制至关重要.
线性通路调解者与固体瘤的进展有关,并且可以预测成年AML的结果.
在儿科AML中线性调解者的作用仍然未被探索.

研究的目的:

调查小儿AML中九个菌相关基因的表达.
确定线粒基因表达和儿科AML的生存结果之间的关联.
探索小儿AML的线粒细胞衰变通路内的潜在治疗点.

主要方法:

量化逆转录聚合酶连锁反应 (qRT-PCR) 用于测量90名儿科AML患者和30名对照者的基因表达.
来自Beat AML队列的转录组数据提供了外部验证.
卡普兰-梅尔估计和日志等级测试被用于生存分析.

主要成果:

与对照组相比,所有9个与线粒相关的基因 (PINK1,PARKIN,SQSTM1,NDP52,OPTN,ULK1,MAP1LC3B,FUNDC1,BNIP3) 在儿科AML中显著过度表达.
这种过度表达在Beat AML队列中得到证实,并且在AML亚型中一致.
FUNDC1过度表达与较低的无复发生存期 (RFS) 有显著的关联 (HR=2.039,p=0.044).

结论:

与线粒相关的基因在儿科AML中通过各种亚型被上调.
FUNDC1过度表达成为小儿AML下级RFS的潜在预后生物标志物.
准线粒菌通路为儿科AML提供了一个有前途的治疗途径.

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...

Differentiation of Common Myeloid Progenitor Cells

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
