概括

在急性髓性白血病 (AML) 中的FLT3-ITD突变通过ERO1α降低ER压力,将葡萄糖代谢转移到细胞存活和化疗抵抗的糖解.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
细胞的新陈代谢

背景情况:

FLT3-ITD突变在急性髓性白血病 (AML) 中很常见,并且与不良结果有关.
这些突变导致一个构成性活跃的FLT3受体被保留在内质网膜 (ER).

研究的目的:

研究FLT3-ITD突变诱导的ER保留如何影响ER恒温.
确定ER应激和ERO1α在具有FLT3-ITD突变的AML细胞的代谢重编程中的作用.

主要方法:

在具有或没有FLT3-ITD突变的AML细胞中分析ER压力标志物.
评估ERO1α表达及其对细胞存活和化学抵抗的功能影响.
评估与FLT3突变状态和ER压力水平相关的葡萄糖代谢途径 (线粒体与甘油性).

主要成果:

具有FLT3-ITD突变的AML细胞由于ERO1α过度表达而表现出减少的ER压力.
过度表达ERO1α对于FLT3-ITD突变AML细胞的生存和化学抵抗至关重要.
通过ERO1α,FLT3突变状态决定葡萄糖代谢:突变细胞有利于糖解,而非突变细胞利用线粒体通路.

结论:

FLT3-ITD突变状态影响了AML中的ER稳态和代谢重编程.
通过代谢适应,ERO1α在调解FLT3-ITD突变所赋予的生存优势方面发挥着关键作用.

Receptor Downregulation in MVBs

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

Regulation of the Unfolded Protein Response

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
