DNA methylation and DNA methyltransferases [PDF]

open access: yesEpigenetics & Chromatin, 2017
The prevailing views as to the form, function, and regulation of genomic methylation patterns have their origin many years in the past, at a time when the structure of the mammalian genome was only dimly perceived, when the number of protein-encoding ...

Light‐Activation of DNA‐Methyltransferases [PDF]

open access: yesAngewandte Chemie International Edition, 2021
Abstract5‐Methylcytosine (5mC), the central epigenetic mark of mammalian DNA, plays fundamental roles in chromatin regulation. 5mC is written onto genomes by DNA methyltransferases (DNMT), and perturbation of this process is an early event in carcinogenesis.

DNA methyltransferase-1 in acute myeloid leukaemia: beyond the maintenance of DNA methylation

open access: yesAnnals of Medicine, 2022
DNA methylation is considered an essential epigenetic event during leukaemogenesis and the emergence of drug resistance, which is primarily regulated by DNA methyltransferases.

Ezh2-dCas9 and KRAB-dCas9 enable engineering of epigenetic memory in a context-dependent manner. [PDF]

open access: yes, 2019
BackgroundRewriting of the epigenome has risen as a promising alternative to gene editing for precision medicine. In nature, epigenetic silencing can result in complete attenuation of target gene expression over multiple mitotic divisions.

DNMT3B in vitro knocking-down is able to reverse embryonal rhabdomyosarcoma cell phenotype through inhibition of proliferation and induction of myogenic differentiation [PDF]

open access: yes, 2016
Aberrant DNA methylation has been frequently observed in many human cancers, including rhabdomyosarcoma (RMS), the most common soft tissue sarcoma in children.

Decreased expression of MGMT in correlation with aberrant DNA methylation in esophageal cancer patients from North India

open access: yesTumor Biology, 2017
O-6-methylguanine-DNA methyltransferase, DNA repair gene, has been found to be involved with the pathogenesis of the esophageal cancer. DNA hypermethylation and other factors have been suggested to downregulate O-6-methylguanine-DNA methyltransferase. In

Functional Crosstalk between Lysine Methyltransferases on Histone Substrates: The Case of G9A/GLP and Polycomb Repressive Complex 2 [PDF]

open access: yes, 2015
Significance: Methylation of histone H3 on lysine 9 and 27 (H3K9 and H3K27) are two epigenetic modifications that have been linked to several crucial biological processes, among which are transcriptional silencing and cell differentiation.

Inhibition of DNA Methyltransferase Inhibits DNA Replication [PDF]

open access: yesJournal of Biological Chemistry, 2000
Ectopic expression of DNA methyltransferase transforms vertebrate cells, and inhibition of DNA methyltransferase reverses the transformed phenotype by an unknown mechanism. We tested the hypothesis that the presence of an active DNA methyltransferase is required for DNA replication in human non-small cell lung carcinoma A549 cells.
