The Diminution of R‐Loops Generated by LncRNA DSP‐AS1 Inhibits DSP Gene Transcription to Impede the Re‐Epithelialization During Diabetic Wound Healing

open access: yesAdvanced Science, Volume 12, Issue 12, March 27, 2025.
Down‐regulated LncRNA DSP‐AS1, the diminution of R‐loop formation, reduced Ten‐eleven translocation 3 (TET3) occupancy, inhibited DNA demethylation at the DSP promoter, and disrupted re‐epithelialization process proceed sequentially during delayed diabetic wound healing.

TDP1 deficiency sensitizes human cells to base damage via distinct topoisomerase I and PARP mechanisms with potential applications for cancer therapy [PDF]

open access: yes, 2013
Base damage and topoisomerase I (Top1)-linked DNA breaks are abundant forms of endogenous DNA breakage, contributing to hereditary ataxia and underlying the cytotoxicity of a wide range of anti-cancer agents.

Simulating 3-symbol Turing machines with SIMD||DNA [PDF]

open access: yesarXiv, 2021
SIMD||DNA is a model of DNA strand displacement allowing parallel in-memory computation on DNA storage. We show how to simulate an arbitrary 3-symbol space-bounded Turing machine with a SIMD||DNA program, giving a more direct and efficient route to general-purpose information manipulation on DNA storage than the Rule 110 simulation of [Wang, Chalk ...

Sequence Context‐Agnostic TadA‐Derived Cytosine Base Editors for Genome‐Wide Editing in Zebrafish

open access: yesAdvanced Science, Volume 12, Issue 14, April 10, 2025.
zTadA‐CBEs, developed by introducing key mutations into TadA8e, enable efficient and precise sequence context‐agnostic cytosine base editing. Specifically, zTadA‐BE4max and zTadA‐BEmv provide complementary editing windows, while zTadA‐SpRY‐BE4max offers PAM‐flexible editing.

An AP endonuclease functions in active DNA demethylation and gene imprinting in Arabidopsis [corrected]. [PDF]

open access: yesPLoS Genetics, 2015
Active DNA demethylation in plants occurs through base excision repair, beginning with removal of methylated cytosine by the ROS1/DME subfamily of 5-methylcytosine DNA glycosylases.

Characterization of demethylating DNA glycosylase ROS1 from Nicotiana tabacum L.

open access: yesВавиловский журнал генетики и селекции, 2022
One of the main mechanisms of epigenetic regulation in higher eukaryotes is based on the methylation of cytosine at the C5 position with the formation of 5-methylcytosine (mC), which is further recognized by regulatory proteins.

DNA glycosylases: in DNA repair and beyond [PDF]

open access: yes, 2018
The base excision repair machinery protects DNA in cells from the damaging effects of oxidation, alkylation, and deamination; it is specialized to fix single-base damage in the form of small chemical modifications. Base modifications can be mutagenic and/

Detection of Damaged DNA Bases by DNA Glycosylase Enzymes [PDF]

open access: yesBiochemistry, 2010
A fundamental and shared process in all forms of life is the use of DNA glycosylase enzymes to excise rare damaged bases from genomic DNA. Without such enzymes, the highly ordered primary sequences of genes would rapidly deteriorate. Recent structural and biophysical studies are beginning to reveal a fascinating multistep mechanism for damaged base ...
