AHR and oral cavity squamous cell carcinoma: Results in the zebrafish metastasis assay showing that both AHR inhibitors (CH223191, CB7993113) and agonists (DIM) profoundly block TNBC (MDA-MB-231), oral squamous cell carcinoma (HSC3), and/or cervical cancer (HeLa) metastasis imply that a similar situation may exist in other cancer types.
