Random Mutagenesis in Porphyromonas gingivalis Enables Isolation of Mutants With Enhanced Secreted Protease Activity. [PDF]

open access: yesMol Oral Microbiol
ABSTRACT Porphyromonas gingivalis is a key pathogen in periodontitis, with secreted proteases as major virulence factors. We developed a screening method to generate and identify P. gingivalis mutants with elevated protease activity. Mutations were induced using the mutagens 2,6‐diaminopurine (2,6‐DAP) or ethyl methanesulfonate (EMS), and the ...

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.

A mathematical model for cancer risk and accumulation of mutations caused by replication errors and external factors.

open access: yesPLoS ONE, 2023
Replication errors influence mutations, and thus, lifetime cancer risk can be explained by the number of stem-cell divisions. Additionally, mutagens also affect cancer risk, for instance, high-dose radiation exposure increases lifetime cancer risk ...

The Mutagenic Impact of Environmental Exposures in Human Cells and Cancer: Imprints Through Time

open access: yesFrontiers in Genetics, 2021
During life, the DNA of our cells is continuously exposed to external damaging processes. Despite the activity of various repair mechanisms, DNA damage eventually results in the accumulation of mutations in the genomes of our cells.
