Genome-wide analysis of interactions between ATP-dependent chromatin remodeling and histone modifications

BMC Genomics, 2009
Background ATP-dependent chromatin remodeling and the covalent modification of histones play central roles in determining chromatin structure and function.

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.

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 ...

A Double-Edged Role for SIRT7 in Cancer: Can Anti-Cancer Immunity Tip the Balance?

Pharmaceuticals
Background/Objectives: Sirtuin 7 (SIRT7), a nuclear NAD+-dependent deacylase, plays multifaceted and sometimes opposing roles in tumorigenesis. By preserving chromatin architecture and genome integrity, SIRT7 protects against malignant transformation ...

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 ...

The SIRT7-nucleolus connection in cancer: ARF enters the fray

Molecular & Cellular Oncology
The nucleolar enzyme sirtuin 7 (SIRT7) promotes cancer progression in certain malignancies, likely in part by controlling ribosome biosynthesis. Recently, we discovered that SIRT7 destabilizes the cyclin dependent kinase inhibitor 2A (CDKN2A, known as ...

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.

Dietary polyphenols and chromatin remodeling

Critical Reviews in Food Science and Nutrition, 2017
Polyphenols are the most abundant phytochemicals in fruits, vegetables, and plant-derived beverages. Recent findings suggest that polyphenols display the ability to reverse adverse epigenetic regulation involved in pathological conditions, such as obesity, metabolic disorder, cardiovascular and neurodegenerative diseases, and various forms of cancer ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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
