Five hundred human RFP-MDA-MB-231 cells (TNBC), RFP-HSC3 (oral squamous cell carcinoma), or RFP-HeLa (cervical carcinoma) cells were injected into the perivitiline space of two-day-old zebrafish larvae and fish were treated with one of two AHR inhibitors in the water, 10 μM CB7993113 or 10 μM CH223191. The gene discussed is AHR; the disease is cervical carcinoma.
