Single known extracts’ constituents, such as ATX-II and AOH were previously shown to activate the AhR, increase CYP 1A1 enzyme activity, which was shown via EROD assay and impact CYP 1A1 mRNA transcription at corresponding concentrations in KYSE 510 oesophageal cancer cells, while AME exhibited its potency primarily in HepG2 cells [51]. This evidence concerns the gene AHR and carcinoma of esophagus.
