Evidence for two DNA repair enzymes for 8-hydroxyguanine (7,8-dihydro-8-oxoguanine) in human cells.
Journal of Biological Chemistry, 1993 Two DNA repair enzymes for 8-hydroxyguanine (also known as 7,8-dihydro-8-oxoguanine; OH8Gua, oxo8Gua) have been identified in human HeLa cell nuclear extract.

Development of a rapid electrophoretic assay for genomic DNA damage quantification
Ecotoxicology and Environmental Safety, 2021 Accuracy, sensitivity, simplicity, reproducibility, and low-cost are desirable requirements for genotoxicity assessment techniques. Here we describe a simple electrophoretic assay for genomic DNA lesions quantification (EAsy-GeL) based on subjecting DNA ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

DNA mismatch repair enzyme expression in synovial tissue [PDF]
Annals of the Rheumatic Diseases, 2004 Oxidative stress in RA synovial tissue can cause DNA damage and suppress the DNA mismatch repair (MMR) system in cultured synoviocytes. This mechanism includes two enzyme complexes, hMutSalpha (hMSH2/hMSH6) and hMutSbeta (hMSH2/hMSH3).To examine the expression and distribution of MMR enzymes in synovial tissues from patients with arthritis and from ...

Ageing And Cancer As Diseases Of Epigenesis [PDF]
, 2009 Cancer and ageing are often said to be diseases of development. During the past fifty years, the genetic components of cancer and ageing have been intensely investigated since development, itself, was seen to be an epiphenomenon of the genome.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Homologous Recombination under the Single-Molecule Fluorescence Microscope [PDF]
, 2019 Homologous recombination (HR) is a complex biological process and is central to meiosis and for repair of DNA double-strand breaks. Although the HR process has been the subject of intensive study for more than three decades, the complex protein–protein ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
