Increasingly efficient chromatin binding of cohesin and CTCF supports chromatin architecture formation during zebrafish embryogenesis [PDF]

open access: yesNature Communications
The three-dimensional folding of chromosomes is essential for nuclear functions such as DNA replication and gene regulation. The emergence of chromatin architecture is thus an important process during embryogenesis.

Acetic acid produced by Staphylococcus epidermidis remodels chromatin architecture and suppresses gene expression in Malassezia restricta [PDF]

open access: yesmBio
The skin microbiome is composed of diverse microbial communities that engage in interkingdom interactions, influencing host physiology and microbial balance. Although Malassezia restricta and Staphylococcus epidermidis are codominant members of the human

Cohesin Mutations Induce Chromatin Conformation Perturbation of the H19/IGF2 Imprinted Region and Gene Expression Dysregulation in Cornelia de Lange Syndrome Cell Lines

open access: yesBiomolecules, 2021
Traditionally, Cornelia de Lange Syndrome (CdLS) is considered a cohesinopathy caused by constitutive mutations in cohesin complex genes. Cohesin is a major regulator of chromatin architecture, including the formation of chromatin loops at the imprinted ...

Dynamic 3D genome reorganization during development and metabolic stress of the porcine liver

open access: yesCell Discovery, 2022
Liver development is a complex process that is regulated by a series of signaling pathways. Three-dimensional (3D) chromatin architecture plays an important role in transcriptional regulation; nonetheless, its dynamics and role in the rapid transition of

Multi-level remodelling of chromatin underlying activation of human T cells

open access: yesScientific Reports, 2021
Remodelling of chromatin architecture is known to regulate gene expression and has been well characterized in cell lineage development but less so in response to cell perturbation.

Cryo-ET study from in vitro to in vivo revealed a general folding mode of chromatin with two-start helical architecture

open access: yesCell Reports, 2023
Summary: The organization and dynamics of chromatin fiber play crucial roles in regulating DNA accessibility for gene expression. Here we combine cryoelectron tomography (cryo-ET), sub-volume averaging, and 3D segmentation to visualize the in vitro and ...

Targeting Epigenetic Mechanisms in Vascular Aging

open access: yesFrontiers in Cardiovascular Medicine, 2022
Environment, diseases, lack of exercise, and aged tendency of population have becoming crucial factors that induce vascular aging. Vascular aging is unmodifiable risk factor for diseases like diabetes, hypertension, atherosclerosis, and hyperlipidemia ...

Methylation of RNA polymerase II non-consensus Lysine residues marks early transcription in mammalian cells

open access: yeseLife, 2015
Dynamic post-translational modification of RNA polymerase II (RNAPII) coordinates the co-transcriptional recruitment of enzymatic complexes that regulate chromatin states and processing of nascent RNA.
