The Effect of Sulphur Atom on the Structure of Biomolecule 2-Thiocytosine in the Gas-Phase, Solid-State, and Hydrated Forms and in DNA–DNA Microhelices as Compared to Canonical Ones

open access: yesMolecules
This study is focused on the effects of the sulphur atom in position 2 of the cytosine molecule, 2-thiocytosine (2TC), on the molecular structural parameters in the isolated state, as well as in the hydration, solid state arrangement, Watson–Crick pairs,

Use of a molecular beacon based fluorescent method for assaying uracil DNA glycosylase (Ung) activity and inhibitor screening

open access: yesBiochemistry and Biophysics Reports, 2021
Uracil DNA glycosylases are an important class of enzymes that hydrolyze the N-glycosidic bond between the uracil base and the deoxyribose sugar to initiate uracil excision repair.

CRISPR/Cas9-mediated phage resistance is not impeded by the DNA modifications of phage T4.

open access: yesPLoS ONE, 2014
Bacteria rely on two known DNA-level defenses against their bacteriophage predators: restriction-modification and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR-associated (Cas) systems.

Mutation of a major CG methylase alters genome-wide lncRNA expression in rice

open access: yesG3: Genes, Genomes, Genetics, 2021
Plant long non-coding RNAs (lncRNAs) function in diverse biological processes, and lncRNA expression is under epigenetic regulation, including by cytosine DNA methylation. However, it remains unclear whether 5-methylcytosine (5mOsMET1-2OsMET1-2−

Association of 5-hydroxymethylation and 5-methylation of DNA cytosine with tissue-specific gene expression

open access: yesEpigenetics, 2017
Differentially methylated or hydroxymethylated regions (DMRs) in mammalian DNA are often associated with tissue-specific gene expression but the functional relationships are still being unraveled.

Recent Progress in Electrochemical Biosensors for Detection of DNA Methylation and Methyltransferase Activity

open access: yesInternational Journal of Electrochemical Science, 2019
DNA methylation is one of the most studied epigenetic modifications of DNA. The methylation at C-5 position of cytosine has been proved to be related to a wide range of biological phenomena. Therefore, it is very important to develop a simple, sensitive,

Evidence That DNA (Cytosine-5) Methyltransferase Regulates Synaptic Plasticity in the Hippocampus [PDF]

open access: yesJournal of Biological Chemistry, 2006
DNA (cytosine-5) methylation represents one of the most widely used mechanisms of enduring cellular memory. Stable patterns of DNA methylation are established during development, resulting in creation of persisting cellular phenotypes. There is growing evidence that the nervous system has co-opted a number of cellular mechanisms used during development

Crosstalk between 6-methyladenine and 4-methylcytosine in Geobacter sulfurreducens exposed to extremely low-frequency electromagnetic field

open access: yesiScience
Summary: 4-Methylcytosine (4mC) and 6-methyladenine (6mA) are the most prevalent types of DNA modifications in prokaryotes. However, whether there is crosstalk between 4mC and 6mA remain unknown.
