The nuclear matrix protein HNRNPU maintains 3D genome architecture globally in mouse hepatocytes.

ABSTRACT: Eukaryotic chromosomes are folded into higher-order conformations to coordinate genome functions. In addition to long-range chromatin loops, recent chromosome conformation capture (3C)-based studies have indicated higher levels of chromatin structures including compartments and topologically associating domains (TADs), which may serve as units of genome organization and functions. However, the molecular machinery underlying these hierarchically three-dimensional (3D) chromatin architectures remains poorly understood. Via high-throughput assays, including in situ Hi-C, DamID, ChIP-seq, and RNA-seq, we investigated roles of the Heterogeneous Nuclear Ribonucleoprotein U (HNRNPU), a nuclear matrix (NM)-associated protein, in 3D genome organization. Upon the depletion of HNRNPU in mouse hepatoc
