Roles and regulation of histone acetylation in hepatocellular carcinoma
Frontiers in Genetics, 2022 Hepatocellular Carcinoma (HCC) is the most frequent malignant tumor of the liver, but its prognosis is poor. Histone acetylation is an important epigenetic regulatory mode that modulates chromatin structure and transcriptional status to control gene ...

Epigenetic Chromatin Silencing: Bistability and Front Propagation
, 2007 The role of post-translational modification of histones in eukaryotic gene regulation is well recognized. Epigenetic silencing of genes via heritable chromatin modifications plays a major role in cell fate specification in higher organisms.

A cancer-specific antigen drives histone acetylation by stabilizing the acetyltransferases
Cell ReportsSummary: Histone acetylation is a critical modification that regulates gene expression by modulating chromatin structure and function. Histone acetyltransferases are essential for maintaining acetylation homeostasis, and the disruption of this balance ...

Downregulating ANP32A rescues synapse and memory loss via chromatin remodeling in Alzheimer model
Molecular Neurodegeneration, 2017 Background The impairment of histone acetylation is causally linked to the cognitive decline in Alzheimer’s disease (AD). In addition to histone acetyltransferases (HATs) and histone deacetylases (HDACs), inhibitor of acetyltransferases (INHAT) can also ...

Molecular Basis of KAT2A Selecting Acyl-CoA Cofactors for Histone Modifications
Research, 2023 Emerging discoveries about undocumented acyltransferase activities of known histone acetyltransferases (HATs) advance our understandings in the regulation of histone modifications. However, the molecular basis of HATs selecting acyl coenzyme A (acyl-CoA)

Identification of acetyltransferase genes (HAT1 and KAT8) regulating HBV replication by RNAi screening [PDF]
, 2015 Background: The initiation of hepatitis B virus (HBV) replication involves the formation of covalently closed circular DNA (cccDNA) and its transcription into pregenomic RNA (pgRNA) in hepatocyte nuclei.

Characterization of Histone Deacetylase Mechanisms in Cancer Development
Frontiers in Oncology, 2021 Over decades of studies, accumulating evidence has suggested that epigenetic dysregulation is a hallmark of tumours. Post-translational modifications of histones are involved in tumour pathogenesis and development mainly by influencing a broad range of ...
