The SMC5/6 complex leads to a loss of H3K27ac on KSHV chromatin.

(a-c) Ectopic expression of SMC6 decreases the levels of H3K27ac on KSHV genome. (a) H3K27ac on viral RTA was measured with ChIP-qPCR assay. ChIP was performed among latently infected control cells and SMC6-overexpressing cells by using antibodies against total H3 or H3K27ac. The recruitment of H3 and H3K27ac on KSHV…

Simultaneous Mapping of Enhancers and Enhancer RearrangementsEnhancer Rearrangements with Paired-End H3K27ac ChIP-seq

We describe a protocol for H3K27ac ChIP paired-end sequencing and computational analysis of rearrangements. Our approach can be used to simultaneously map enhancers and their activity and to identify structural variations at enhancers. Since changes in enhancer activity and new enhancer translocations both play a major role in tumor initiation,…

New study investigates the epigenetic drift of time passing

A new research paper was published in Aging (Aging-US) on the cover of Volume 14, Issue 12, entitled, “Time makes histone H3 modifications drift in mouse liver.” Aging is known to involve epigenetic histone modifications, which are associated with transcriptional changes, occurring throughout the entire lifespan of an individual. “So…

Allelic expression imbalance of PIK3CA mutations is frequent in breast cancer and prognostically significant

Subjects Normal breast and tumor samples were obtained with the written informed consent from donors and appropriate approval from local ethical committees, with the detailed information described in the respective original publications: normal tissue9, METABRIC14, TCGA35. Differential allelic expression analysis DNA and total RNA from 64 samples of normal breast…

Understanding the relationship between large-scale chromatin structure and gene expression

Abstract Eukaryotic genomes are packaged into a complex DNA, RNA, and protein rich chromatin fibre, creating an interdependent functional relationship between the structure of the chromatin and the activity of the genetic features stored within. The composition of active genomic regions is weighted towards transcription factors, co-activating proteins, and active …

TET2 regulates immune tolerance in chronically activated mast cells

This article was originally published here JCI Insight. 2022 Apr 8;7(7):e154191. doi: 10.1172/jci.insight.154191. ABSTRACT Mutation of the TET2 DNA-hydroxymethylase has been associated with a number of immune pathologies. The disparity in phenotype and clinical presentation among these pathologies leads to questions regarding the role of TET2 mutation in promoting disease…

The role of ATXR6 expression in modulating genome stability and transposable element repression in Arabidopsis

Significance The plant-specific H3K27me1 methyltransferases ATXR5 and ATXR6 play integral roles connecting epigenetic silencing with genomic stability. However, how H3K27me1 relates to these processes is poorly understood. In this study, we performed a comprehensive transcriptome analysis of tissue- and ploidy-specific expression in a hypomorphic atxr5/6 mutant and revealed that the…

Pan-AMPK activator O304 prevents gene expression changes and remobilisation of histone marks in islets of diet-induced obese mice

O304 treatment prevents islet gene expression signature changes induced by HFD We have previously demonstrated that the AMPK activator O304 improves blood glucose homeostasis in both human T2D subjects as well as in high-fat diet induced obese and diabetic mouse models. In the present study, we have now analysed the…
