Enzymatic approaches for profiling cytosine methylation and hydroxymethylation

open access: yesMolecular Metabolism, 2022
Background: In mammals, modifications to cytosine bases, particularly in cytosine-guanine (CpG) dinucleotide contexts, play a major role in shaping the epigenome.

Ureido cytosine and cytosine-containing acrylic copolymers

open access: yesPolymer Chemistry, 2016
Ureido-cytosine pendant groups contributed to random acrylic copolymers with enhanced thermomechanical performance, well-defined morphologies, and reduced water uptake.

Consecutive Silver(I) Ion Incorporation into Oligonucleotides containing Cytosine‐Cytosine Mispairs [PDF]

open access: yesChemPlusChem, 2020
AbstractInvited for this month's cover is the group of Prof. Heinz‐Bernhard Kraatz from the University of Toronto, Canada. The cover picture shows the consecutive incorporation of AgI ions into a DNA duplex containing adjacent C−C mispairs. Read the full text of the article at 10.1002/cplu.202000607.

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine. [PDF]

open access: yesPLoS ONE, 2014
We demonstrate that a mutant of uracil DNA glycosylase (N123D:L191A) distinguishes between cytosine and methylcytosine. Uracil DNA glycosylase (UDG) efficiently removes uracil from DNA in a reaction in which the base is flipped into the enzyme's active ...

Factors Influencing the Nitrogen-Source Dependent Flucytosine Resistance in Cryptococcus Species

open access: yesmBio, 2023
Flucytosine (5-FC) is an antifungal agent commonly used for treatment of cryptococcosis and several other systemic mycoses. In fungi, cytosine permease and cytosine deaminase are known major players in flucytosine resistance by regulating uptake and ...

A genome-phenome association study in native microbiomes identifies a mechanism for cytosine modification in DNA and RNA

open access: yeseLife, 2021
Shotgun metagenomic sequencing is a powerful approach to study microbiomes in an unbiased manner and of increasing relevance for identifying novel enzymatic functions.

Clinical implications of cytosine deletion of exon 5 of P53 gene in non small cell lung cancer patients

open access: yesSouth Asian Journal of Cancer, 2016
Aim: Lung cancer is considered to be the most common cancer in the world. In humans, about 50% or more cancers have a mutated tumor suppressor p53 gene thereby resulting in accumulation of p53 protein and losing its function to activate the target genes ...

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Global DNA cytosine methylation as an evolving trait: phylogenetic signal and correlated evolution with genome size in Angiosperms

open access: yesFrontiers in Genetics, 2015
DNA cytosine methylation is a widespread epigenetic mechanism in eukaryotes, and plant genomes commonly are densely methylated. Genomic methylation can be associated with functional consequences such as mutational events, genomic instability or altered ...
