Meat-cooking mutagens and risk of renal cell carcinoma

open access: yesBritish Journal of Cancer, 2011
Background:High-temperature cooked meat contains two families of carcinogens, heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). Given the kidneys’ role in metabolism and urinary excretion of these compounds, we investigated meat ...

Random Mutagenesis in Porphyromonas gingivalis Enables Isolation of Mutants With Enhanced Secreted Protease Activity

open access: yesMolecular Oral Microbiology, EarlyView.
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 ...

Haploid Mutation Mapping Identifies a Homoeologous Non‐Reciprocal Translocation Linked to Reduced Fibre and Enhanced Protein in Brassica napus

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

Navigating the Genetic Risk of Chemotherapy‐Induced Hearing Loss in the Stria Vascularis

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 846-858, April 2026.
Cisplatin is a chemotherapy drug that causes permanent hearing loss by damaging a critical tissue lining the inner ear, called the stria vascularis (SV). Currently, the molecular mechanisms of SV damage are largely unknown and the incidence of ototoxicity in patients cannot be reliably predicted.

Analysis of Regulatory Inhalation Unit Risk Estimates for Cobalt: Comparison to Epidemiological Data

open access: yesRisk Analysis, Volume 46, Issue 4, April 2026.
ABSTRACT Several cancer potency estimates have been proposed by regulatory agencies to characterize the dose response of cobalt and/or cobalt compounds. The objective of this research is to investigate whether these proposed cancer potency estimates for certain cobalt substances align with the available epidemiology literature.
