Low-Dose Benzo(a)pyrene and Its Epoxide Metabolite Inhibit Myogenic Differentiation in Human Skeletal Muscle-Derived Progenitor Cells

open access: yes, 2017
The risk of low birth weights is elevated in prenatal exposure to polycyclic aromatic hydrocarbons (PAHs), which are ubiquitous environmental pollutants generated from combustion of organic compounds, including cigarette smoke. We hypothesized that benzo(

PharmVar GeneFocus: CYP1A2—Clinical Impact, Genetic Variation, and Updated Nomenclature

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The Pharmacogene Variation Consortium (PharmVar) provides nomenclature for the highly polymorphic human CYP1A2 gene. CYP1A2 plays a crucial role in the biotransformation of several commonly used drugs, including antipsychotics, antidepressants, anxiolytics, and methylxanthines.

A Modular Synthesis of Isoindole/Indolizine Hybrids via the 1,3‐Dipolar Cycloaddition of Pyridine‐Based Mesoionics with Benzyne

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An approach to prepare pyrido[2,1‐a]isoindoles via the cycloaddition of pyridine‐based 1,3‐dipoles and benzyne is described, offering modular access to a range of substituted products by systematic tuning of the dipole. A modular strategy for the synthesis of fused indolizine/isoindole hybrids, pyrido[2,1‐α]isoindoles, via cycloaddition of pyridine ...

Comparing Transcriptomic Responses to Chemicals Across Six Species Using the EcoToxChip RNASeq Database

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The EcoToxChip project includes RNA‐sequencing data from experiments involving model (Japanese quail, fathead minnow, African clawed frog) and ecological (double‐crested cormorant, rainbow trout, northern leopard frog) species at multiple life stages (whole embryo and adult) exposed to eight chemicals of environmental concern known to perturb ...

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Benzo(a)pyrene metabolism: Role of bioalkylation

open access: yes, 2007
Previous studies of the metabolic activation of chemical carcinogens including benzo(a)pyrene have demonstrated that selected aromatic hydrocarbons can undergo a series of biological substitution reactions in tissue cytosol preparations when in the ...
