Coevolution of the CDCA7-HELLS ICF-related nucleosome remodeling complex and DNA methyltransferases

open access: yeseLife, 2023
5-Methylcytosine (5mC) and DNA methyltransferases (DNMTs) are broadly conserved in eukaryotes but are also frequently lost during evolution. The mammalian SNF2 family ATPase HELLS and its plant ortholog DDM1 are critical for maintaining 5mC. Mutations in

Targeted DNA methylation using an artificially bisected M.HhaI fused to zinc fingers. [PDF]

open access: yesPLoS ONE, 2012
Little is known about the effects of single DNA methylation events on gene transcription. The ability to direct the methylation toward a single unique site within a genome would have broad use as a tool to study the effects of specific epigenetic changes

DNA methyltransferase DNMT3a contributes to neuropathic pain by repressing Kcna2 in primary afferent neurons

open access: yesNature Communications, 2017
Nerve injury induces changes in gene transcription in dorsal root ganglion (DRG) neurons, which may contribute to nerve injury-induced neuropathic pain. DNA methylation represses gene expression.

DNA methylation impacts gene expression and ensures hypoxic survival of Mycobacterium tuberculosis. [PDF]

open access: yesPLoS Pathogens, 2013
DNA methylation regulates gene expression in many organisms. In eukaryotes, DNA methylation is associated with gene repression, while it exerts both activating and repressive effects in the Proteobacteria through largely locus-specific mechanisms.

Hypoxia/reoxygenation attenuates migration and invasion of human extracellular villus trophoblast cells via DNA methyltransferase pathway

open access: yes陆军军医大学学报, 2023
Objective To explore the regulative mechanism of hypoxia/reoxygen (H/R) for invasion ability of extravillous trophoblast (EVT). Methods Immortalized human EVT cell line HTR-8/SVneo in early pregnancy, primary EVT cells isolated from the villi of placenta

DNA Methyltransferases in Depression: An Update [PDF]

open access: yesFrontiers in Psychiatry, 2020
Depression is one of the most common psychiatric disorders affecting public health. Studies over the past years suggest that the methylations of some specific genes such as BDNF, SLC6A4, and NR3C1 play an important role in the development of depression.

Alteration in the expression of MGMT and RUNX3 due to non-CpG promoter methylation and their correlation with different risk factors in esophageal cancer patients

open access: yesTumor Biology, 2017
Promoter methylation reflects in the inactivation of different genes like O 6 -methylguanine-DNA methyltransferase DNA repair gene and runt-related transcription factor 3, a known tumor suppressor gene in various cancers such as esophageal cancer.

MadID, a Versatile Approach to Map Protein-DNA Interactions, Highlights Telomere-Nuclear Envelope Contact Sites in Human Cells

open access: yesCell Reports, 2018
Summary: Mapping the binding sites of DNA- or chromatin-interacting proteins is essential to understanding biological processes. DNA adenine methyltransferase identification (DamID) has emerged as a comprehensive method to map genome-wide occupancy of ...

On the evolutionary origin of eukaryotic DNA methyltransferases and Dnmt2.

open access: yesPLoS ONE, 2011
The Dnmt2 enzymes show strong amino acid sequence similarity with eukaryotic and prokaryotic DNA-(cytosine C5)-methyltransferases. Yet, Dnmt2 enzymes from several species were shown to methylate tRNA-Asp and had been proposed that eukaryotic DNA ...

Critical threshold levels of DNA methyltransferase 1 are required to maintain DNA methylation across the genome in human cancer cells

open access: yesGenome Research, 2017
Reversing DNA methylation abnormalities and associated gene silencing, through inhibiting DNA methyltransferases (DNMTs) is an important potential cancer therapy paradigm.
