概括

解蛋白1 (UCP1) 在纤维化中是下调的. UCP1的升高降低了氧化应激和细胞外矩阵的积累,为慢性病 (CKD) 提供了新的治疗点.

科学领域:

线粒体生物学和细胞代谢
科和病研究研究.
氧化应激和纤维化机制.

背景情况:

间纤维化是慢性病 (CKD) 中的一个关键病理过程,导致末期病.
目前对纤维化的诊断和治疗策略仍然有限.
解蛋白1 (UCP1) 在CKD病原体中的作用尚不清楚.

研究的目的:

研究解蛋白1 (UCP1) 在脏间歇性纤维化发展中的作用.
探索UCP1作为缓解纤维化的治疗标的潜力.

主要方法:

在体内 (单侧尿管阻塞) 和体内 (TGF-β1刺激的HK2细胞) 建立了纤维化模型.
评估了UCP1的表达,表皮-介质细胞过渡 (EMT) 标志物,细胞外基质 (ECM) 积累和反应性氧物种 (ROS) 生产.
利用UCP1过度表达,UCP1激动剂 (CL316243) 和SIRT3敲击 (siRNA) 来调节细胞通路.

主要成果:

在纤维化患者和模型中,UCP1表达显著下调.
在纤维化中,UCP1上调和激素治疗逆转了EMT和ECM的积累.
通过增强SIRT3稳定性,UCP1降低了ROS的产生,而SIRT3倒置则增加了ROS.

结论:

提高UCP1表达抑制氧化应激通过稳定SIRT3,从而减少EMT和ECM积累.
这种机制可以缓解脏间歇性纤维化,这表明UCP1是CKD的一个有前途的治疗点.
这些发现为治疗慢性病提供了新的见解和潜在的策略.

关键词:

慢性病 (CKD) 是一种慢性病.反应性氧物种 (ROS) 是一种反应性氧物种.脏间歇性纤维化脏间歇性纤维化在SIRT3中,SIRT3是最重要的.在UCP1中,UCP1是UCP1.

The Unfolded Protein Response

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

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...

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
