- 环境健康
- 蛋白质组学
- 生物标志物发现
背景情况:
- 长期暴露在 (U) 中会给健康带来风险,其潜在的分子机制尚不清楚.
- 细胞外囊泡 (EVs) 调节细胞间的通信,并调节细胞功能.
研究的目的:
- 在前U矿工中调查U矿工任期与血清衍生EV蛋白质和血细胞因子的相关性.
- 与细胞因子相比,评估EV衍生蛋白作为慢性U暴露的潜在生物标志物.
主要方法:
- 分析了39名前U矿工的血清和血.
- 使用质谱学分离,鉴定和确定EV的蛋白质谱.
- 使用回归分析量化了血细胞因子,并评估了与采矿持有时间的关联.
主要成果:
- 八个小EV和四个大EV的蛋白质与采矿经历有显著的相关性,不论年龄如何.
- 像补充C1r和维生素K依赖蛋白S这样的特定EV蛋白显示出强烈的逆相关性.
- 与EV蛋白相关性不同的是,细胞因子与矿业持有权相关性因年龄而混.
结论:
- 血清EV衍生的蛋白质签名显示为U暴露的生物标志物,不受年龄的影响.

Nuclear Export of mRNA
9.3K
Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...

Overview of Exosomes
3.9K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

Microbial Bioremediation of Uranium
71
Microorganisms play a critical role in the transformation and immobilization of uranium in contaminated environments through four main pathways: bioreduction, biosorption, bioaccumulation, and biomineralization. These mechanisms reduce uranium’s toxicity and prevent its migration through groundwater systems, offering sustainable approaches for in situ bioremediation.Bioreduction of UraniumBioreduction is driven by anaerobic bacteria such as certain strains of Geobacter and Shewanella,...
