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.

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 ...

Linking long non-coding RNAs and SWI/SNF complexes to chromatin remodeling in cancer

Molecular Cancer, 2017
Chromatin remodeling controls gene expression and signaling pathway activation, and aberrant chromatin structure and gene dysregulation are primary characteristics of human cancer progression. Recent reports have shown that long non-coding RNAs (lncRNAs)

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Mechanism of chromatin remodeling [PDF]

Proceedings of the National Academy of Sciences, 2010
Results from biochemical and structural studies of the RSC chromatin-remodeling complex prompt a proposal for the remodeling mechanism: RSC binding to the nucleosome releases the DNA from the histone surface and initiates DNA translocation (through one or a small number of DNA base pairs); ATP binding completes translocation, and ATP hydrolysis resets ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

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

Chromatin Remodeling and Cancer [PDF]

Cancer Biology & Therapy, 2003
The fate of the cell relies on a delicate balance between gene expression and repression. The transcriptional control of the genome is maintained not only by transcription factors but also chromatin remodeling proteins. The purpose of the chromatin remodeling proteins is to alter the nucleosome architecture such that genes are exposed to or hidden from

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

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 ...
