Standard fluorescent imaging of live cells is highly genotoxic [PDF]

, 2013
Fluorescence microscopy is commonly used for imaging live mammalian cells. Here, we describe studies aimed at revealing the potential genotoxic effects of standard fluorescence microscopy.

Bacillus subtilis RNase HII Is Inefficient at Processing Guanosine Monophosphate and Damaged Ribonucleotides

Molecular Microbiology, EarlyView.
Bacillus subtilis RNase HII corrects ribonucleotide errors and mismatched ribonucleotides, but not damaged ribonucleotides. Mismatched ribonucleotides would also serve as substrates for mismatch repair while damaged ribonucleotides would be addressed through base excision repair.

The Emerging Role of Ten-Eleven Translocation 1 in Epigenetic Responses to Environmental Exposures. [PDF]

, 2020
Mounting evidence from epidemiological studies and animal models has linked exposures to environmental factors to changes in epigenetic markers, especially in DNA methylation.

[Uracil-DNA glycosylases].

Postepy biochemii, 2009
Uracil is one of four nitrogen bases, most frequently found in normal RNA. Uracyl can be found also in DNA as a result of enzymatic or non-enzymatic deamination of cytosine as well as misincorporation of dUMP instead of dTMP during DNA replication. Uracil from DNA can be removed by DNA repair enzymes with apirymidine site as an intermediate.

Cas9‐Embedding Hyperactive TadA8e Confers Efficient and Highly Specific A‐To‐G Base Editing in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Adenine base editors (ABEs) produce precise A‐to‐G conversion in the genomic target sites without causing double‐strand breaks. However, the hyperactive adenosine deaminase TadA8e raises safety concerns on genome‐wide off‐target edits. We engineered 11 chimeric proteins for ABEs (CP‐ABEs) by embedding hyperactive TadA8e within Cas9 nickase to ...

DNA hydroxymethylation levels are altered in blood cells from Down syndrome persons enrolled in the MARK-AGE project [PDF]

, 2017
Down syndrome (DS) is caused by the presence of part or an entire extra copy of chromosome 21, a phenomenon that can cause a wide spectrum of clinically defined phenotypes of the disease. Most of the clinical signs of DS are typical of the ageing process

The PagDMG6341–PagWD40–PagPOLD4 Module Coordinates Base Excision Repair in ‘84K’ Poplar (Populus alba × P. glandulosa)

Plant Biotechnology Journal, EarlyView.
ABSTRACT Base excision repair (BER) is a critical pathway for repairing damaged DNA bases in cells; however, the mechanisms of protein recruitment and interaction in this pathway remain largely unexplored in higher plants. In this study, we used ‘84K’ poplar (Populus alba × P.

Pyrimido[1,2-a]-purin-10(3H)-one, M(1)G, is less prone to artifact than base oxidation [PDF]

, 2005
Pyrimido[1,2-a]-purin-10(3H)-one (M(1)G) is a secondary DNA damage product arising from primary reactive oxygen species (ROS) damage to membrane lipids or deoxyribose.

A stage‐dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean

Plant, Cell &Environment, EarlyView.
Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.
