A mathematical model of DNA degradation: Possible role of magnetic nanoparticles [PDF]
A mathematical model of genome degradation is proposed that takes into account a variable rate of mutation and increasing number of cells in a developing human organism. The model explains known properties of cancer development, in particular, a synergism between different mutagens and an increased probability of cancer in the early years of life.

A two-component transposon system based on the Ac element of maize was used as a mutagen in Arabidopsis thaliana. Transposition of a Ds element marked with a hygromycin-resistance gene was activated from four different locations in the Arabidopsis genome.

Mutagen sensitivity: a genetic predisposition factor for cancer.
Mutagen sensitivity, measured by quantifying the chromatid breaks induced by mutagens in short-term cultures of peripheral blood lymphocytes, has been used as an indirect measure of DNA repair capacity.

A series of benzimidazolium chlorides and their 2‐mercapto were successfully synthesized and characterized. Cytotoxic activity assays revealed that certain synthesized compounds exhibited efficacy against cancer cell lines. To investigate the possible mechanism underlying their cytotoxic effects, the binding interactions of the three most active ...

ABSTRACT Introduction Gastric cancer (GC) remains among the top five global health problems. Therefore, comprehending the tumor energetic behavior is critical to understanding its progression. This study aimed to investigate mitochondrial DNA (mtDNA) alterations in GC cancer cell lines in an animal model.

Micronucleus induction by 915 MHz Radiofrequency Radiation in Vicia faba root tips [PDF]
The mutagenic effect of radiofrequency electromagnetic field (RF-EMF) is evaluated by the micronucleus (MN) test in secondary roots of Vicia faba seedlings. Root exposures were carried out with 915 MHz continuous wave (CW) radiation for 72h, at power densities of 25, 38, 50 W/m$^2$.

The human, F-actin-based cytoskeleton as a mutagen sensor
Background Forty years ago the actin cytoskeleton was determined to be disrupted in fibroblasts from persons with DNA repair-defective, hereditary colon cancer, with no clear connection between the cytoskeleton and DNA repair defects at that time ...
