Loss of 5-hydroxymethylcytosine correlates with increasing morphologic dysplasia in melanocytic tumors [PDF]

open access: yes, 2015
DNA methylation is the most well studied epigenetic modification in cancer biology. 5-hydroxymethylcytosine is an epigenetic mark that can be converted from 5-methylcytosine by the ten-eleven translocation gene family.

Liposomal Delivery of L‐2‐Hydroxyglutarate for Targeting Epigenetic Dysregulation in Osteoarthritis

open access: yesAdvanced NanoBiomed Research, EarlyView.
Osteoarthritis involves cartilage degeneration, inflammation, and epigenetic dysregulation. A liposomal formulation of the TET1 inhibitor L‐2‐hydroxyglutarate to overcome rapid joint clearance was developed. The formulation showed good physicochemical properties, reduced inflammatory and catabolic gene expression in chondrocytes, and alleviated ...

Tet-assisted bisulfite sequencing of 5-hydroxymethylcytosine [PDF]

open access: yesNature Protocols, 2012
A complete understanding of the potential function of 5-hydroxymethylcytosine (5-hmC), a DNA cytosine modification in mammalian cells, requires an accurate single-base resolution sequencing method. Here we describe a modified bisulfite-sequencing method, Tet-assisted bisulfite sequencing (TAB-seq), which can identify 5-hmC at single-base resolution, as

Characterization of 5-methylcytosine and 5-hydroxymethylcytosine in human placenta cell types across gestation

open access: yesEpigenetics, 2019
The placenta is an important organ in pregnancy, however, very little is understood about placental development at a molecular level. This includes the role of epigenetic mechanisms and how they change throughout gestation.

Analysis of genome-wide 5-hydroxymethylation of blood samples stored in different anticoagulants: opportunities for the expansion of clinical resources for epigenetic research

open access: yesEpigenetics, 2023
Background: Elucidating epigenetic mechanisms could provide new biomarkers for disease diagnosis and prognosis. Technological advances allow genome-wide profiling of 5-hydroxymethylcytosines (5hmC) in liquid biopsies.

Methyltransferase‐Directed Derivatization of 5‐Hydroxymethylcytosine in DNA [PDF]

open access: yesAngewandte Chemie International Edition, 2011
Cytosine modification by AdoMet–dependent DNA methyltransferases is part of an epigenetic regulatory network in vertebrates. Here we show that, in the absence of AdoMet, bacterial cytosine-5 methyltransferases can catalyze condensation of aliphatic thiols and selenols to 5-hydroxymethylcytosine in DNA yielding 5-chalcogenomethyl derivatives.

5-Hydroxymethylcytosine: generation, fate, and genomic distribution [PDF]

open access: yesCurrent Opinion in Cell Biology, 2013
5-Methylcytosine (5mC) can be converted to 5-hydroxymethylcytosine (5hmC) in mammalian cells by the ten-eleven translocation (Tet) family of dioxygenases. While 5mC has been extensively studied, we have just started to understand the distribution and function of 5hmC in mammalian genomes.

Pancreatic Cancer Early Detection Biomarkers for High‐Risk Individuals: Insights From the PRECEDE Consortium

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers due to its asymptomatic progression, late‐stage diagnosis, and treatment resistance. Efforts in early detection have centered on identifying imaging features and liquid biopsy biomarkers capable of detecting PDAC and its high‐grade precursors before clinical symptoms ...

Analysis of TET expression/activity and 5mC oxidation during normal and malignant germ cell development.

open access: yesPLoS ONE, 2013
During mammalian development the fertilized zygote and primordial germ cells lose their DNA methylation within one cell cycle leading to the concept of active DNA demethylation.
