Crystal structure of mimivirus uracil-DNA glycosylase. [PDF]
Cytosine deamination induced by stresses or enzymatic catalysis converts deoxycytidine into deoxyuridine, thereby introducing a G to A mutation after DNA replication.

Poxvirus uracil‐DNA glycosylase—An unusual member of the family I uracil‐DNA glycosylases [PDF]
AbstractUracil‐DNA glycosylases are ubiquitous enzymes, which play a key role repairing damages in DNA and in maintaining genomic integrity by catalyzing the first step in the base excision repair pathway. Within the superfamily of uracil‐DNA glycosylases family I enzymes or UNGs are specific for recognizing and removing uracil from DNA.

Evolution of Prime Editing: Enhancing Efficiency and Expanding Capacity
Most rare diseases are caused by genetic mutations. Prime editing (PE) has emerged as a versatile tool capable of inducing diverse mutations without generating DNA double‐strand breaks. Despite its significant clinical potential, PE faces limitations in terms of efficiency and scalability.

Bacillus Calmette-Guerin Increases Base Excision Repair in Bladder Cancer Cells
Objective:Most patients with non-muscle-invasive bladder cancer (NMIBC) do not respond to intravesical Bacillus Calmette-Guerin (BCG) immunotherapy and have high risk of NMIBC recurrence and progression.

Uracil-DNA glycosylases preferentially excise mispaired uracil [PDF]
We have investigated the substrate specificity of human, viral and bacterial uracil-DNA glycosylases employing as substrate double-stranded oligonucleotides containing in the same position of the 5′-32P-labelled strand an uracil residue facing, on the complementary strand, guanine (mimicking cytosine deamination) or adenine (mimicking dUTP ...

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

Both a DNA lesion and an intermediate for antibody maturation, uracil is primarily processed by base excision repair (BER), either initiated by uracil-DNA glycosylase (UNG) or by single-strand selective monofunctional uracil DNA glycosylase (SMUG1).

Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

DNA Checkpoint and Repair Factors Are Nuclear Sensors for Intracellular Organelle Stresses-Inflammations and Cancers Can Have High Genomic Risks. [PDF]
Under inflammatory conditions, inflammatory cells release reactive oxygen species (ROS) and reactive nitrogen species (RNS) which cause DNA damage. If not appropriately repaired, DNA damage leads to gene mutations and genomic instability.
