Transcription-associated breaks in Xeroderma Pigmentosum group D cells from patients with combined features of Xeroderma Pigmentosum and Cockayne Syndrome [PDF]

open access: yes, 2005
Defects in the XPD gene can result in several clinical phenotypes, including xeroderma pigmentosum (XP), trichothiodystrophy, and, less frequently, the combined phenotype of XP and Cockayne syndrome (XP-D/CS).

Relationship between CpG and non-CpG DNA methylation in human lymphocytes assessed with comet assay [PDF]

open access: yesThe Ukrainian Biochemical Journal
Tissue-specific DNA methylation plays an important role in the regulation of many functional processes. The methylation level in single cells can be assessed using the comet assay (single-cell gel electrophoresis), a simple and cost-effective technique ...

The comet assay – from toy to tool

open access: yesFrontiers in Genetics, 2015
The comet assay is nowadays the most common method for measuring DNA damage and repair in single cells. It is based on the microelectrophoretic study published by Ostling and Johanson (1984) and was developed by Singh and coworkers (1988) to a versatile ...

Protective effects of phenolic acids on mercury-induced DNA damage in precision-cut kidney slices [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2019
Objective(s): Precision-cut tissue slices are considered an organotypic 3D model widely used in biomedical research. The comet assay is an important screening test for early genotoxicity risk assessment that is mainly applied on in vitro models.  The aim

Discovery of macrocyclic inhibitors of apurinic/apyrimidinic endonuclease 1 [PDF]

open access: yes, 2019
Apurinic/apyrimidinic endonuclease 1 (APE1) is an essential base excision repair enzyme that is upregulated in a number of cancers, contributes to resistance of tumors treated with DNA-alkylating or -oxidizing agents, and has recently been identified as ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

ATM deficiency results in accumulation of DNA-Topoisomerase I covalent intermediates in neural cells [PDF]

open access: yes, 2013
Accumulation of peptide-linked DNA breaks contributes to neurodegeration in humans. This is typified by defects in tyrosyl DNA phosphodiesterase 1 (TDP1) and human hereditary ataxia.
