Differential Grainy head binding correlates with variation in chromatin structure and gene expression in Drosophila melanogaster

BMC Genomics, 2022
Phenotypic evolution is often caused by variation in gene expression resulting from altered gene regulatory mechanisms. Genetic variation affecting chromatin remodeling has been identified as a potential source of variable gene expression; however, the ...

The Arp8 and Arp4 module acts as a DNA sensor controlling INO80 chromatin remodeling

Nature Communications, 2018
Nuclear actin and actin-related proteins (Arps) are key components of chromatin remodeling and modifying complexes. Although Arps are essential for the functions of chromatin remodelers, their specific roles and mechanisms are unclear. Here we define the

Molecular profiling of biliary tract cancers reveals distinct genomic landscapes between circulating and tissue tumor DNA

Experimental Hematology & Oncology
Biliary tract cancers (BTCs) are heterogeneous malignancies with dismal prognosis due to tumor aggressiveness and poor response to limited current therapeutic options.

Oligodendrocyte precursor survival and differentiation requires chromatin remodeling by Chd7 and Chd8

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Oligodendrocyte precursor cells (OPCs) constitute the main proliferative cells in the adult brain and deregulation of OPC proliferation-differentiation balance results in either glioma formation or defective (re)myelination.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Mitochondrial fatty acid oxidation is stimulated by red light irradiation

FEBS Letters, EarlyView.
Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

Inhibition of chromatin condensation disrupts planar cell migration

Nucleus
Cell migration involves the actin cytoskeleton, and recently recognized nuclear involvement. In this study, we explore the impact of chromatin remodeling on cell migration using NIH 3T3 cells and a scratch wound assay subjected to pharmacological ...

Minor groove binder distamycin remodels chromatin but inhibits transcription.

PLoS ONE, 2013
The condensed structure of chromatin limits access of cellular machinery towards template DNA. This in turn represses essential processes like transcription, replication, repair and recombination.

Chromatin Remodeling of Colorectal Cancer Liver Metastasis is Mediated by an HGF‐PU.1‐DPP4 Axis

Advanced Science, 2021
Colorectal cancer (CRC) metastasizes mainly to the liver, which accounts for the majority of CRC‐related deaths. Here it is shown that metastatic cells undergo specific chromatin remodeling in the liver.

Arabidopsis SWR1-associated protein methyl-CpG-binding domain 9 is required for histone H2A.Z deposition. [PDF]

, 2019
Deposition of the histone variant H2A.Z by the SWI2/SNF2-Related 1 chromatin remodeling complex (SWR1-C) is important for gene regulation in eukaryotes, but the composition of the Arabidopsis SWR1-C has not been thoroughly characterized.
