HUWE1‐Mediated Degradation of MUTYH Facilitates DNA Damage and Mitochondrial Dysfunction to Promote Acute Kidney Injury

open access: yesAdvanced Science, Volume 12, Issue 13, April 3, 2025.
MutY homolog (MUTYH) protein levels are significantly decreased in the kidneys of acute kidney injury (AKI) patients. The upregulation of the E3 ligase HUWE1 mediates the degradation of MUTYH in renal tubular epithelial cells, exacerbating DNA damage in both the nucleus and mitochondria, thereby promoting AKI. Targeting the HUWE1/MUTYH pathway may be a

Complex Roles of NEIL1 and OGG1: Insights Gained from Murine Knockouts and Human Polymorphic Variants

open access: yesDNA, 2022
DNA glycosylases promote genomic stability by initiating base excision repair (BER) in both the nuclear and mitochondrial genomes. Several of these enzymes have overlapping substrate recognition, through which a degree of redundancy in lesion recognition

Self-assembling DNA-caged particles: nanoblocks for hierarchical self-assembly [PDF]

open access: yes, 2008
DNA is an ideal candidate to organize matter on the nanoscale, primarily due to the specificity and complexity of DNA based interactions. Recent advances in this direction include the self-assembly of colloidal crystals using DNA grafted particles. In this article we theoretically study the self-assembly of DNA-caged particles. These nanoblocks combine

7,8-Dihydro-8-oxoadenine, a highly mutagenic adduct, is repaired by Escherichia coli and human mismatch-specific uracil/thymine-DNA glycosylases [PDF]

open access: yes, 2012
Hydroxyl radicals predominantly react with the C(8) of purines forming 7,8-dihydro-8-oxoguanine (8oxoG) and 7,8-dihydro-8-oxoadenine (8oxoA) adducts, which are highly mutagenic in mammalian cells.

Identification of Escherichia coli Mismatch-specific Uracil DNA Glycosylase as a Robust Xanthine DNA Glycosylase [PDF]

open access: yesJournal of Biological Chemistry, 2010
The gene for the mismatch-specific uracil DNA glycosylase (MUG) was identified in the Escherichia coli genome as a sequence homolog of the human thymine DNA glycosylase with activity against mismatched uracil base pairs. Examination of cell extracts led us to detect a previously unknown xanthine DNA glycosylase (XDG) activity in E. coli.

Plasma DNMT1 Activity for Assessing Tumor Burden and Predicting Neoadjuvant Therapy Response in Breast Cancer

open access: yesAdvanced Science, EarlyView.
In this work, a detection method is presented for the activity of plasma DNA methyltransferase 1 (DNMT1), namely DNMT1 Identification by Variable Activity (DIVA). DIVA can detect plasma DNMT1 at levels as low as 10−7 U mL−1, also it successfully evaluated tumor burden and predicted the neoadjuvant therapy responses of breast cancer patients.

High expression of uracil DNA glycosylase determines C to T substitution in human pluripotent stem cells

open access: yesMolecular Therapy: Nucleic Acids, 2022
Precise genome editing of human pluripotent stem cells (hPSCs) is crucial not only for basic science but also for biomedical applications such as ex vivo stem cell therapy and genetic disease modeling.

Capacity of DNA Data Embedding Under Substitution Mutations [PDF]

open access: yes, 2011
A number of methods have been proposed over the last decade for encoding information using deoxyribonucleic acid (DNA), giving rise to the emerging area of DNA data embedding. Since a DNA sequence is conceptually equivalent to a sequence of quaternary symbols (bases), DNA data embedding (diversely called DNA watermarking or DNA steganography) can be ...

DNA Charge Transport within the Cell [PDF]

open access: yes, 2015
The unique characteristics of DNA charge transport (CT) have prompted an examination of roles for this chemistry within a biological context. Not only can DNA CT facilitate long-range oxidative damage of DNA, but redox-active proteins can couple to the ...

A novel uracil-DNA glycosylase family related to the helix-hairpin-helix DNA glycosylase superfamily [PDF]

open access: yesNucleic Acids Research, 2003
Cytosine bases can be deaminated spontaneously to uracil, causing DNA damage. Uracil-DNA glycosylase (UDG), a ubiquitous uracil-excising enzyme found in bacteria and eukaryotes, is one of the enzymes that repair this kind of DNA damage. To date, no UDG-coding gene has been identified in Methanococcus jannaschii, although its entire genome was ...
