RNA gradients: Shapers of 3D genome architecture

Curr Opin Cell Biol. 2022 Feb:74:7-12. doi: 10.1016/j.ceb.2021.12.001. Epub 2022 Jan 5.


A growing body of evidence points to a role of nuclear RNAs (nucRNAs) in shaping the three-dimensional (3D) architecture of the genome within the nucleus of a eukaryotic cell. nucRNAs are non-homogeneously distributed within the nucleus where they can form global and local gradients that might contribute to instructing the formation and coordinating the function of different types of 3D genome structures. In this article, we highlight the available literature supporting a role of nucRNAs as 3D genome shapers and propose that nucRNA gradients are key mediators of genome structure and function.
