摘要

越来越多的证据表明,核体,rna和细胞核内蛋白质的凝聚体,是通过液-液相分离组装的。一些核体,如旁斑,是由一类被称为建筑rna的rna构成的。从材料科学的角度来看,rna被归类为聚合物,在软物质物理学中得到了广泛的研究。虽然软物质物理学有可能提供重要的见解,但它并不直接适用,因为转录和其他生化过程将rna与该领域研究的其他聚合物区分开来。因此,融合分子生物学和软物质物理学的跨学科研究为研究核体提供了一个强有力的途径。本文介绍了这些跨学科研究在核体组装和调节方面提供的生物物理学见解。

Biophysical Aspect of Assembly and Regulation of Nuclear Bodies Scaffolded by Architectural RNA

Biophysical Aspect of Assembly and Regulation of Nuclear Bodies Scaffolded by Architectural RNA
A growing body of evidence suggests that nuclear bodies, condensates of RNAs and proteins within the nucleus, are assembled through liquid–liquid phase separation. Some nuclear bodies, such as paraspeckles, are scaffolded by a class of RNAs known as architectural RNAs. From a materials science perspective, RNAs are categorized as polymers, which have been extensively studied in soft matter physics. While soft matter physics has the potential to provide significant insights, it is not directly applicable because transcription and other biochemical processes differentiate RNAs from other polymers studied in this field. Therefore, an interdisciplinary research fusing molecular biology and soft matter physics offers a powerful approach to studying nuclear bodies. This review introduces the biophysical insights provided by such interdisciplinary research in the assembly and regulation of nuclear bodies.
