Title:

Materials and methods

Test guideline
Qualifier:
no guideline available
Principles of method if other than guideline:
AhR ligand activity was measured by using the yeast AhR signaling assay. The genes of the human AhR and its heterodimer partner, AhR nuclear translocator (Arnt), are co-expressed, and AhR ligand activity can be detected and quantified by measuring the beta-galactosidase activity resulting by AhR-mediated transcriptional activation of a lacZ reporter plasmid.

Applicant's summary and conclusion

Conclusions:
Quinoline is about three orders of magnitude less active than BaP.
Executive summary:

Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor through which dioxins and carcinogenic polycyclic aromatic hydrocarbons cause altered gene expression and toxicity.

A screening assay has been performed using the yeast AhR signaling assay.

Quinoline does not activate this receptor in a significant extent.
