Differential chromatin accessibility in peripheral blood mononuclear cells underlies COVID-19 disease severity prior to seroconversion

Scientific Reports, 2022
SARS-CoV-2 infection triggers profound and variable immune responses in human hosts. Chromatin remodeling has been observed in individuals severely ill or convalescing with COVID-19, but chromatin remodeling early in disease prior to anti-spike protein ...

Engineered Chromatin Remodeling Proteins for Precise Nucleosome Positioning

Cell Reports, 2019
Summary: Regulation of chromatin structure is essential for controlling access of DNA to factors that require association with specific DNA sequences. Here we describe the development and validation of engineered chromatin remodeling proteins (E-ChRPs ...

Basis of specificity for a conserved and promiscuous chromatin remodeling protein

eLife, 2021
Eukaryotic genomes are organized dynamically through the repositioning of nucleosomes. Isw2 is an enzyme that has been previously defined as a genome-wide, nonspecific nucleosome spacing factor.

Chromatin accessibility underlies synthetic lethality of SWI/SNF subunits in ARID1A-mutant cancers. [PDF]

, 2017
ARID1A, a subunit of the SWI/SNF chromatin remodeling complex, is frequently mutated in cancer. Deficiency in its homolog ARID1B is synthetically lethal with ARID1A mutation.

PTEN in Chromatin Remodeling [PDF]

Cold Spring Harbor Perspectives in Medicine, 2019
The tumor suppressor phosphatase and tension homolog (PTEN) is frequently mutated in human cancers, and it functions in multiple ways to safeguard cells from tumorigenesis. In the cytoplasm, PTEN antagonizes the PI3K/AKT pathway and suppresses cellular proliferation and survival.

Common CHD8 Genomic Targets Contrast With Model-Specific Transcriptional Impacts of CHD8 Haploinsufficiency. [PDF]

, 2018
The packaging of DNA into chromatin determines the transcriptional potential of cells and is central to eukaryotic gene regulation. Case sequencing studies have revealed mutations to proteins that regulate chromatin state, known as chromatin remodeling ...

Global Regulatory DNA Potentiation by SMARCA4 Propagates to Selective Gene Expression Programs via Domain-Level Remodeling

Cell Reports, 2020
Summary: The human genome encodes millions of regulatory elements, of which only a small fraction are active within a given cell type. Little is known about the global impact of chromatin remodelers on regulatory DNA landscapes and how this translates to

Understanding the role of chromatin remodeling in the regulation of circadian transcription in Drosophila. [PDF]

, 2015
Circadian clocks enable organisms to anticipate daily changes in the environment and coordinate temporal rhythms in physiology and behavior with the 24-h day-night cycle. The robust cycling of circadian gene expression is critical for proper timekeeping,
