Lysine acetyltransferase 5 in EGFR mutated non-small cell lung cancer [PDF]

, 2018
Histone modifications are crucial in activities such as transcriptional activation, gene silencing, and epigenetic cellular memory. In particular, lysine acetylation via lysine (K) acetyltransferases (KATs) has been implicated in cancer development ...

O-GlcNAcase:promiscuous hexosaminidase or key regulator of O-GlcNAc signalling? [PDF]

, 2014
O-GlcNAc signaling is regulated by an opposing pair of enzymes: O-GlcNAc transferase installs and O-GlcNAcase (OGA) removes the modification from proteins.

Evolutionary origin of O-acetyltransferases responsible for glucomannan acetylation in land plants.

New Phytologist, 2019
• Mannans are an abundant cell wall polysaccharide in bryophytes, seedless vascular plants and gymnosperms. A previous study has shown that mannan acetylation in Arabidopsis and konjac is mediated by mannan O-acetyltransferases belonging to the DUF ...

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

Molecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

O-acetylated Gangliosides as Targets for Cancer Immunotherapy

Cells, 2020
O-acetylation of sialic acid residues is one of the main modifications of gangliosides, and modulates ganglioside functions. O-acetylation of gangliosides is dependent on sialyl-O-acetyltransferases and sialyl-O-acetyl-esterase activities.

Is acetylation a metabolic rheostat that regulates skeletal muscle insulin action? [PDF]

, 2015
Skeletal muscle insulin resistance, which increases the risk for developing various metabolic diseases, including type 2 diabetes, is a common metabolic disorder in obesity and aging.

Polymorphism of Human Acetyltransferases

Environmental Health Perspectives, 1994
Acetylation by arylamine N-acetyltransferases (NATs) is a major route in the metabolism of numerous drugs and carcinogens. Recent studies suggest that the same enzymes also catalyze N,O-transacetylation and O-acetylation. A genetic polymorphism of clinical relevance divides the human population into slow and rapid acetylators of arylamines.

Inhibition of histone acetyltransferase by glycosaminoglycans [PDF]

Journal of Cellular Biochemistry, 2008
AbstractHistone acetyltransferases (HATs) are a class of enzymes that participate in modulating chromatin structure and gene expression. Altered HAT activity has been implicated in a number of diseases, yet little is known about the regulation of HATs.

Influenza A virus nucleoprotein is acetylated by histone acetyltransferases PCAF and GCN5

Journal of Biological Chemistry, 2018
Histone acetylation plays crucial roles in transcriptional regulation and chromatin organization. Viral RNA of the influenza virus interacts with its nucleoprotein (NP), whose function corresponds to that of eukaryotic histones.

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

Molecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.
