Chemical investigation of light induced DNA bipyrimidine damage and repair [PDF]

, 2011
In all organisms, genetic information is stored in DNA and RNA. Both of these macromolecules are damaged by many exogenous and endogenous events, with UV irradiation being one of the major sources of damage.

DNA Hypomethylation Is One of the Epigenetic Mechanisms Involved in Salt‐Stress Priming in Soybean Seedlings

Plant, Cell &Environment, EarlyView.
ABSTRACT Salt‐stress priming enhances the tolerance of plants against subsequent exposure to a similar stress. Priming‐induced transcriptomic reprogramming is mediated by multiple epigenetic mechanisms, the best known of which is histone modifications. However, not much is known about other epigenetic responses.

Research progress on the role of the NEIL family in cancer

Frontiers in Cell and Developmental Biology
Cancer is the primary cause of death worldwide. Cancer occurrence and progression are closely associated with DNA damage repair. DNA glycosylase were the first enzymes to initiate base excision repair, and the Nei-like DNA glycosylase (NEIL) family has ...

Over‐Expression of a Phycocyanin‐Interferon Fusion and Differential Cleaving Efficiency in Cyanobacteria (Synechocystis sp. PCC 6803)

Biotechnology and Bioengineering, Volume 123, Issue 3, Page 752-762, March 2026.
ABSTRACT Recombinant protein expression in heterologous biological systems is an expanding field in synthetic biology. Photosynthetic organisms have the potential to provide an efficient low‐cost platform for recombinant protein production because they require minimal growth nutrients and are less susceptible to zoonotic and other contaminants ...

A common SNP in the UNG gene decreases ovarian cancer risk in BRCA2 mutation carriers

Molecular Oncology, 2019
Single nucleotide polymorphisms (SNPs) in DNA glycosylase genes involved in the base excision repair (BER) pathway can modify breast and ovarian cancer risk in BRCA1 and BRCA2 mutation carriers.

Uracil-DNA glycosylase. Purification and properties of uracil-DNA glycosylase from Micrococcus luteus.

Journal of Biological Chemistry, 1982
A uracil-DNA-glycosylase from Micrococcus luteus has been purified more than 3,000-fold. The enzyme preparation appears homogeneous, according to the results of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It is devoid of nonspecific endonucleases, specific endonucleases for apurinic and apyrimidinic sites, 3-methyladenine or 7 ...

APE1 Activity is Controlled by Non‐G‐Quadruplex Conformations in Single‐ and Double‐Stranded G‐Quadruplex Constructs

Chemistry – A European Journal, Volume 32, Issue 5, 2 February 2026.
G‐quadruplex (G4) folding in DNA is inhibitory to AP endonuclease, although the protein still binds well to G4s. Curiously, partially folded G‐rich sequences, possibly transient hairpins, containing AP are very good substrates for cleavage by APE1. Herein, the enzyme activity and G4 folding are studied in single‐stranded vs. duplex contexts.

Detection of uracil within DNA using a sensitive labeling method for in vitro and cellular applications [PDF]

, 2016
The role of uracil in genomic DNA has been recently re-evaluated. It is now widely accepted to be a physiologically important DNA element in diverse systems from specific phages to antibody maturation and Drosophila development.

Improvement of EPO Transgene Detection From Polymeric Dried Blood Spots for Antidoping Application

Drug Testing and Analysis, Volume 18, Issue 2, Page 230-238, February 2026.
This article presents an optimized protocol for gene doping detection. Starting from one spot DBS (20 μL), concentrated DNA was obtained and real‐time PCR parameters were adjusted for increased detection. Robust detection of 5000 copies/mL of transgene was validated for polymeric device TASSO M‐20.

Role of enhancer of zeste homolog 2 polycomb protein and its significance in tumor progression and cell differentiation [PDF]

, 2013
Epigenetics is a branch of genetics that focuses on the heritable changes of DNA or associated proteins, other than DNA sequence variations, which carry information content during cell division [1,2].
