Distribution of 5-Hydroxymethylcytosine in Different Human Tissues

Journal of Nucleic Acids, 2011
5-hydroxymethylcytosine (5-hmC) is a modified form of cytosine recently found in mammalians and is believed, like 5-methylcytosine, to also play an important role in switching genes on and off.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Role of Tet1 and 5-hydroxymethylcytosine in cocaine action [PDF]

Nature Neuroscience, 2015
Ten-eleven translocation (TET) enzymes mediate the conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), which is enriched in brain, and its ultimate DNA demethylation. However, the influence of TET and 5hmC on gene transcription in brain remains elusive.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Dynamics of 5-hydroxymethylcytosine during mouse spermatogenesis [PDF]

Nature Communications, 2013
Little is known about how patterns of DNA methylation change during mammalian spermatogenesis. 5 hmC has been recognized as a stable intermediate of DNA demethylation with potential regulatory functions in the mammalian genome. However, its global pattern in germ cells has yet to be addressed.

Induction of Radiata Pine Somatic Embryogenesis at High Temperatures Provokes a Long-Term Decrease in DNA Methylation/Hydroxymethylation and Differential Expression of Stress-Related Genes

Plants, 2020
Based on the hypothesis that embryo development is a crucial stage for the formation of stable epigenetic marks that could modulate the behaviour of the resulting plants, in this study, radiata pine somatic embryogenesis was induced at high temperatures (

Oncogenic BRAF and KRAS Promote Global DNA Hypomethylation Through a Directed Pathway That Upregulates TET3

Cancer Science, EarlyView.
Oncogenic BRAF and KRAS promote global DNA hypomethylation through a directed pathway that increases the levels of TET3, which helps drive tumorigenesis. ABSTRACT Aberrant epigenetic modification is one of the characteristics of the cancer genome.

5-Hydroxymethylcytosine Is Not Present in Appreciable Quantities in Arabidopsis DNA [PDF]

, 2014
5-Hydroxymethylcytosine (5-hmC) is an intermediate in active demethylation in metazoans, as well as a potentially stable epigenetic mark. Previous reports investigating 5-hydroxymethylcytosine in plants have reached conflicting conclusions.

Tet proteins: on track towards DNA demethylation?

Biomolecular Concepts, 2012
Dynamic DNA methylation is a prerequisite for many developmental processes and maintenance of cellular integrity. In mammals however, mechanisms of active DNA demethylation have for long been elusive.
