Epigallocatechin-3-gallate (EGCG) Alters Histone Acetylation and Methylation and Impacts Chromatin Architecture Profile in Human Endothelial Cells.
Epigallocatechin gallate (EGCG), the main green tea polyphenol, exerts a wide variety of biological actions. Epigenetically, the catechin has been classified as a DNMTs inhibitor, however, its impact on histone modifications and chromatin structure is still poorly understood. The purpose of this study was to find the impact of EGCG on the histone posttranslational modifications machinery and chromatin remodeling in human endothelial cells of both microvascular (HMEC-1) and vein (HUVECs) origin. We analyzed the methylation and acetylation status of histones (Western blotting), as well as assessed the activity (fluorometric assay kit) and gene expression (qPCR) of the enzymes playing a prominent role in shaping the human epigenome. The performed analyses showed that EGCG increases histone acetylation (H3K9/14ac, H3ac), and methylation of both active (H3K4me3) and repressive (H3K9me3) chromatin marks. We also found that the catechin acts as an HDAC inhibitor in cellular and cell-free models. Additionally, we observed that EGCG affects chromatin architecture by reducing the expression of heterochromatin binding proteins: HP1α, HP1γ. Our results indicate that EGCG promotes chromatin relaxation in human endothelial cells and presents a broad epigenetic potential affecting expression and activity of epigenome modulators including HDAC5 and 7, p300, CREBP, LSD1 or KMT2A.Oskar Ciesielski, Marta Biesiekierska, Aneta Balcerczyk

Measuring Histone Deacetylase Inhibition in the Brain.
Histone deacetylases (HDACs) represent a family of enzymes that are targets for epigenetic modulation of genomic activity and may be beneficial in the treatment of many diseases, including cancer and central nervous system disorders. In animal models, HDAC inhibitors have neuroprotective, antiepileptogenic, and antidepressant effects. Assaying HDAC activity provides a robust method for identifying HDAC inhibitors and for assessing their effects under various physiological conditions or after pathological insults. In this unit, a simple and sensitive assay for measuring HDAC activity is described. HDAC activity in tissue lysates can be assessed fluorometrically using a Boc-Lys(Ac) HDAC activity kit. HDACs catalyze the deacetylation of the substrate Boc-Lys(Ac)-AMC. Addition of a trypsin-containing developer converts the deacetylated product to a quantifiable fluorophore that can be used both as a screening method to identify putative HDAC inhibitors and to assess the effects of these inhibitors on tissue and animal epigenetic-modulated phenotypes. © 2018 by John Wiley & Sons, Inc.Doodipala Samba Reddy, Xin Wu, Victoria M Golub, W Mohaiza Dashwood, Roderick H Dashwood

Decreased Histone Deacetylase 2 (HDAC2) in Peripheral Blood Monocytes (PBMCs) of COPD Patients.
Histone deacetylase 2 (HDAC2) is a class I histone deacetylase family member that plays a critical role in suppressing inflammatory gene expression in the airways, lung parenchyma, and alveolar macrophages in patients with chronic obstructive pulmonary disease (COPD). However, the expression of HDAC2 in peripheral blood monocytes (PBMCs), nuclear factor kappa B (NF-κB) p65, and serum inflammatory cytokine levels in COPD patients, smokers, and non-smokers remains unclear.Chunting Tan, Lingling Xuan, Shuhua Cao, Ganggang Yu, Qi Hou, Haoyan Wang
