Dynamic changes in 3D chromatin structure during male gametogenesis in Arabidopsis thaliana

Genome Biology
Background Chromatin higher-order structure plays an important role in genome stability maintenance and gene transcriptional regulation; however, the dynamics of the three-dimensional (3D) chromatin in male gametophytes during the two rounds of mitosis ...

3D chromatin structures associated with ncRNA roX2 for hyperactivation and coactivation across the entire X chromosome

Science Advances
The three-dimensional (3D) organization of chromatin within the nucleus is crucial for gene regulation. However, the 3D architectural features that coordinate the activation of an entire chromosome remain largely unknown. We introduce an omics method, RNA-associated chromatin DNA-DNA interactions, that integrates RNA polymerase II (RNAPII)–

Chromosome-level genomes of Bruchinae reveal the rapid evolution of sex chromosomes and sex-biased genes in seed beetles

Genomics Communications
Structural variations (SVs) provide a material basis for genomic evolution, which can influence gene expression and three-dimensional (3D) genome structure, and even alter complex chromosomal features through regional recombination, copy number variation,

GAT-HiC: Efficient Reconstruction of 3D Chromosome Structure via Residual Graph Attention Neural Networks

IEEE Transactions on Computational Biology and Bioinformatics
Abstract Hi-C is an experimental technique to measure the genome-wide topological dynamics and three-dimensional (3D) shape of chromosomes indirectly via counting the number of interactions between distinct sets of loci. One can estimate the 3D shape of a chromosome over these indirect interaction datasets.

Chromatin interaction-based annotation of regulatory elements reveals dynamic promoter-enhancer interactions in lymphocyte development

iScience
Summary: Stage- and lineage-specific gene expression patterns are controlled by a complex interplay between transcription factors, the epigenetic landscape, and the three-dimensional (3D) structure of the DNA. The 3D structure allows for the formation of

3D chromatin maps of a brown alga reveal U/V sex chromosome spatial organization

Nature Communications
Nuclear three dimensional (3D) folding of chromatin structure has been linked to gene expression regulation and correct developmental programs, but little is known about the 3D architecture of sex chromosomes within the nucleus, and how that impacts ...

3D Chromatin structure estimation from chromosome conformation capture data

, 2017
In this communication we describe ChromStruct4, a method to reconstruct a set of plausible chromatin configurations starting from contact data obtained through Chromosome Conformation Capture techniques. Chromating fibre is modeled as a kinematic chain made of consecutive and partially penetrable beads whose properties (bead size, elasticity, curvature,
