MalariaCometChip for high-throughput quantification of DNA damage in Plasmodium falciparum

open access: yesSTAR Protocols, 2021
Summary: Comet assay is a standard approach for studying DNA damage in malaria, but high-throughput options are not available. The CometChip was previously developed using mammalian cells as a high-throughput version of the comet assay.

Quantifying engineered nanomaterial toxicity: comparison of common cytotoxicity and gene expression measurements [PDF]

open access: yes, 2017
BACKGROUND: When evaluating the toxicity of engineered nanomaterials (ENMS) it is important to use multiple bioassays based on different mechanisms of action.

Modification of comet-FISH technique by using temperature instead of chemical denaturation

open access: yesMethodsX, 2014
Comet-FISH technique is an extension of commonly used comet assay. Its purpose is to determine whether primary DNA damage which comet assay detects occurred within a sequence of interest that is visualized by hybridization of fluorescent probe.

A novel antibacterial peptide derived from Crocodylus siamensis haemoglobin hydrolysate induces membrane permeabilization causing iron dysregulation, oxidative stress and bacterial death [PDF]

open access: yes, 2017
Aims A novel antibacterial peptide from Crocodylus siamensis haemoglobin hydrolysate (CHH) was characterized for antimicrobial activity. Methods and Results CHHs were hydrolysed for 2 h (2 h-CHH), 4 h (4h-CHH), 6 h (6 h-CHH) and 8 h (8 h-CHH). The

TRIP13 is a protein-remodeling AAA+ ATPase that catalyzes MAD2 conformation switching. [PDF]

open access: yes, 2015
The AAA+ family ATPase TRIP13 is a key regulator of meiotic recombination and the spindle assembly checkpoint, acting on signaling proteins of the conserved HORMA domain family.

The Comet Assay: Tails of the (Un)expected. Use of the comet assay in pharmaceutical development.

open access: yesFrontiers in Genetics, 2015
In genotoxicity testing of pharmaceuticals the rodent alkaline comet assay is being increasingly used as a second in vivo assay in addition to the in vivo micronucleus assay to mitigate in vitro positive results as recommended by regulatory guidance.

Evaluation of Cytotoxicity and Genotoxicity of Acacia aroma Leaf Extracts [PDF]

open access: yes, 2014
Acacia aroma, native plant from San Luis, Argentina, is commonly used as antiseptic and for healing of wounds. The present study was conducted to investigate the in vitro cytotoxicity and genotoxicity of hot aqueous extract (HAE) and ethanolic extract ...

Closing the gap: from public concerns about health effects to science-based testing of chemicals

open access: yesFrontiers in Genetics, 2015
The comet assay is a powerful technology for measuring DNA integrity in humans and other organisms at the level of individual cells. The assay is used for research and industrial testing but suffers from a lack of standardisation, which hinders its use ...

DNA single-strand break repair and spinocerebellar ataxia with axonal neuropathy-1 [PDF]

open access: yes, 2007
DNA single-strand breaks (SSBs) are the commonest DNA lesions arising spontaneously in cells, and if not repaired may block transcription or may be converted into potentially lethal/clastogenic DNA double-strand breaks (DSBs).
