Yeast grown in continuous culture systems can detect mutagens with improved sensitivity relative to the Ames test.

open access: yesPLoS ONE, 2021
Continuous culture systems allow for the controlled growth of microorganisms over a long period of time. Here, we develop a novel test for mutagenicity that involves growing yeast in continuous culture systems exposed to low levels of mutagen for a ...

Repair, abort, ignore? Strategies for dealing with UV damage [PDF]

open access: yes, 2011
DNA repair is a prominent member of the nuclear transactions triad (replication, transcription, and repair). Sophisticated mechanisms govern the cellular process of decision-making (to repair or not to repair, to proceed with cell cycle or not and ...

Human urinary mutagenicity after wood smoke exposure during traditional temazcal use. [PDF]

open access: yes, 2014
In Central America, the traditional temazcales or wood-fired steam baths, commonly used by many Native American populations, are often heated by wood fires with little ventilation, and this use results in high wood smoke exposure.

Lethal Mutagenesis of Picornaviruses with N-6-Modified Purine Nucleoside Analogues [PDF]

open access: yes, 2008
RNA viruses exhibit extraordinarily high mutation rates during genome replication. Nonnatural ribonucleosides that can increase the mutation rate of RNA viruses by acting as ambiguous substrates during replication have been explored as antiviral agents ...
