Base excision repair deficient mice lacking the Aag alkyladenine DNA glycosylase. [PDF]

, 1997
3-methyladenine (3MeA) DNA glycosylases remove 3MeAs from alkylated DNA to initiate the base excision repair pathway. Here we report the generation of mice deficient in the 3MeA DNA glycosylase encoded by the Aag (Mpg) gene.

Accumulation of DNA damage alters microRNA gene transcription in Arabidopsis thaliana

BMC Plant Biology, 2022
Background MicroRNAs (miRNAs) and other epigenetic modifications play fundamental roles in all eukaryotic biological processes. DNA damage repair is a key process for maintaining the genomic integrity of different organisms exposed to diverse stresses ...

Engineered Transformer Base Editor with Enhanced Editing Efficiency

Advanced Science, EarlyView.
A highly efficient transformer base editor system achieves robust genomic editing in a humanized mouse model. This work establishes a versatile and translatable platform, opening new avenues for precision gene therapy. ABSTRACT Canonical cytosine base editors (CBEs) achieve precise C‐to‐T conversions without inducing DNA double‐strand breaks (DSBs ...

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

Advanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Chrysanthemum Morifolium–Derived Nanovesicles Reduce Lactate‐Associated Histone Lactylation and Modulate Microglia‐Mediated Neuroinflammation in Sepsis‐Associated Encephalopathy

Advanced Science, EarlyView.
When used to treat sepsis‐associated encephalopathy, Chrysanthemum morifolium–derived nanovesicles can inhibit the H3K18la/NF‐κB axis to regulate microglia‐mediated neuroinflammation. ABSTRACT Sepsis‐associated encephalopathy (SAE)—a complication of the central nervous system in patients with sepsis—markedly diminishes cognitive functions and is linked

A novel process for mutation detection using uracil DNA-glycosylase [PDF]

, 1998
A novel process is presented for the detection of known mutations and polymorphisms in DNA. This process, termed glycosylase mediated polymorphism detection (GMPD) involves amplification of the target DNA using three normal dNTPs and a fourth modified ...

Utilising Uracil DNA Glycosylase to detect the presence of 5-Methylcytosine

, 2014
DNA is regularly subjected to endogenous and exogenous reagents that cause mutations that can be detrimental to a cell if they are not repaired. One class of enzymes responsible for DNA repair is the family of DNA glycosylases and their role is to remove

Immune Modulatory Therapy for Severe Dengue Hemorrhagic Fever in a Patient With Mitochondrial Complex I Deficiency: A Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Dengue virus (DENV) poses a serious global health challenge, particularly in cases of dengue hemorrhagic fever (DHF). Patients with preexisting mitochondrial disorders may be at increased risk for complications due to the specific impact of DENV on mitochondrial‐dependent cellular processes and immune function.

DNA Damage Recognition by Bacterial and Human Adenine-DNA Glycosylases: Insights from Non-Canonical Substrates

Biomolecules
The Escherichia coli adenine-DNA glycosylase (MutY) and its human homologue, MUTYH, protect cells against oxygen-free radical-induced mutagenesis by excising regular adenine impaired with 8-oxo-7,8-dihydro-guanine (8oxoG) in the base excision repair (BER)

Nanoagonist‐mediated spatiotemporal reprogramming of macrophage phenotypes to potentiate tumor immunotherapy

BMEMat, EarlyView.
This review systematically summarizes the major molecular mechanisms governing TAM polarization and their coordinated interactions. It further highlights recent advances in nanoagonist‐based strategies that intervene in these pathways to reprogram TAMs, critically discussing their therapeutic potential, current limitations, and translational prospects.
