Hi-C sequencing data from cortex laboratory rats
The three-dimensional conformation and packaging of chromosomes modulates the spatial organization of the nucleus, orchestrating DNA replication and repair, maintaining genome stability and integrity, and regulating gene expression. Hi-C methods provide high-resolution data on chromatin-to-chromatin interactions both within and among chromosomes at a genome-wide scale. Hi-C resolves topologically-associated domains (TADs) and chromatin loops that are linked to cell-specific transcriptional control. We present a comprehensive Hi-C dataset generated from the frontal cortex of laboratory rats, encompassing a diverse group of inbred strains (SHR/OlaIpcv, BN-Lx/Cub, BXH6/Cub, HXB2/Ipcv, HXB10/Ipcv, HXB23/Ipcv, HXB31/Ipcv, LE/Stm, F344/Stm) and an F1 hybrid (SHR/Olalpcv x BN/NHsdMcwi). This dataset serves as a valuable resource for studying the mechanisms by which three-dimensional chromatin architecture governs gene expression in the brain. Strain-specific variations in genome organization can illuminate the influence of chromatin structure on gene expression, neuronal functionality, and the predisposition to neurological and behavioral disorders.
