In conclusion, the results of the present study indicate that IFNγ, among its pleiotropic effects, is also able to inhibit CXCL8 secretion and cell migration in BRAF V600e mutated BCPAP but not in TPC-1 thyroid cancer cell line bearing the RET/PTC rearrangement. The gene discussed is CXCL8; the disease is thyroid gland carcinoma.
