Human THO–Sin3A interaction reveals new mechanisms to prevent R-loops that cause genome instability [PDF]

open access: yes, 2017
R-loops, formed by co-transcriptional DNA–RNA hybrids and a displaced DNA single strand (ssDNA), fulfill certain positive regulatory roles but are also a source of genomic instability.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

open access: yesMolecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Transcription shapes genome-wide histone acetylation patterns

open access: yesNature Communications, 2021
Histone acetylation is a ubiquitous hallmark of transcription. Here the authors provide evidence that the majority of histone acetylation is dependent on transcription, specifically due to the requirement of RNAPII for the recruitment and activity of ...

Histone-acetylating enzyme of brain [PDF]

open access: yesBiochemical Journal, 1970
1. Acetylation of histones by an enzyme system derived from rat brain and liver (histone acetylase) was studied by using [1-14C]acetyl-CoA as the acetyl group donor. 2. The activity of this enzyme was largely confined to the nucleus. 3. Histone-acetylating activity of cerebral nuclei purified by centrifugation through 1.9m-sucrose was not altered by ...

Improving PARP inhibitor efficacy in bladder cancer without genetic BRCAness by combination with PLX51107

open access: yesMolecular Oncology, EarlyView.
Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

Histone acetylation and CREB binding protein are required for neuronal resistance against ischemic injury. [PDF]

open access: yesPLoS ONE, 2014
Epigenetic transcriptional regulation by histone acetylation depends on the balance between histone acetyltransferase (HAT) and deacetylase activities (HDAC).

Characteristic H3 N-tail dynamics in the nucleosome core particle, nucleosome, and chromatosome

open access: yesiScience, 2022
Summary: The nucleosome core particle (NCP) comprises a histone octamer, wrapped around by ∼146-bp DNA, while the nucleosome additionally contains linker DNA.

Histone Acetylation Regulates Intracellular pH [PDF]

open access: yesMolecular Cell, 2013
Differences in global levels of histone acetylation occur in normal and cancer cells, although the reason why cells regulate these levels has been unclear. Here we demonstrate a role for histone acetylation in regulating intracellular pH (pH(i)). As pH(i) decreases, histones are globally deacetylated by histone deacetylases (HDACs), and the released ...

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Histone acetyltransferase inhibitor CPTH6 preferentially targets lung cancer stem-like cells [PDF]

open access: yes, 2016
Cancer stem cells (CSCs) play an important role in tumor initiation, progression, therapeutic failure and tumor relapse. In this study, we evaluated the efficacy of the thiazole derivative 3-methylcyclopentylidene-[4-(4’-chlorophenyl)thiazol-2-yl ...
