Identifying DNA methylation in a nanochannel
DNA methylation is a stable epigenetic modification, which is well known to be involved in gene expression regulation. In general, however, analyzing DNA methylation requires rather time consuming processes (24–96 h) via DNA replication and protein ...

Functions of PARylation in DNA Damage Repair Pathways
Protein poly ADP-ribosylation (PARylation) is a widespread post-translational modification at DNA lesions, which is catalyzed by poly(ADP-ribose) polymerases (PARPs).

Lack of Z-DNA Conformation in Mitomycin-Modified Polynucleotides Having Inverted Circular Dichroism [PDF]
Poly(dG-dC)· poly(dG-dC) and Micrococcus lysodeikticus DNA were modified by exposure to reductively activated mitomycin C, an antitumor antibiotic. The resulting covalent drug-polynucleotide complexes displayed varying degrees of CD inversions, which are

The size of the nucleosome [PDF]
The structural origin of the size of the 11 nm nucleosomal disc is addressed. On the nanometer length-scale the organization of DNA as chromatin in the chromosomes involves a coiling of DNA around the histone core of the nucleosome.

Comprehensive methylome map of lineage commitment from haematopoietic progenitors. [PDF]
Epigenetic modifications must underlie lineage-specific differentiation as terminally differentiated cells express tissue-specific genes, but their DNA sequence is unchanged.

Crosstalk between epigenetic modification and circRNA in colorectal cancer: recent advances
Colorectal cancer (CRC) is generally regarded as the third frequent malignancy worldwide, while current diagnosis and treatment of the disease are limited.

Chromatin modification by DNA tracking [PDF]
In general, the transcriptional competence of a chromatin domain is correlated with increased sensitivity to DNase I cleavage. A recent observation that actively transcribing RNA polymerase II piggybacks a histone acetyltranferase activity [Wittschieben, B., Otero, G., de Bizemont, T., Fellows, J., Erdjument-Bromage, H., Ohba, R., Li, Y ...

Computer simulations explain mutation-induced effects on the DNA editing by adenine base editors. [PDF]
Adenine base editors, which were developed by engineering a transfer RNA adenosine deaminase enzyme (TadA) into a DNA editing enzyme (TadA*), enable precise modification of A:T to G⋮C base pairs. Here, we use molecular dynamics simulations to uncover the

Methylated DNMT1 and E2F1 Are Targeted for Proteolysis by L3MBTL3 and CRL4DCAF5 Ubiquitin Ligase [PDF]
Many non-histone proteins are lysine methylated and a novel function of this modification is to trigger the proteolysis of methylated proteins. Here, we report that the methylated lysine 142 of DNMT1, a major DNA methyltransferase that preserves ...

Cleavage of phosphorothioated DNA and methylated DNA by the type IV restriction endonuclease ScoMcrA. [PDF]
Many taxonomically diverse prokaryotes enzymatically modify their DNA by replacing a non-bridging oxygen with a sulfur atom at specific sequences. The biological implications of this DNA S-modification (phosphorothioation) were unknown.
