Popis: The AMPK-activator AICAR recently raised great interest for its anti-cancer properties. With specific regard to thyroid cancer, AICAR reduces cancer cell growth, invasion and metastasis. CXCL8, a chemokine with several recognized tumorigenic effects, is abundantly secreted in thyroid cancer microenvironment. The aim of this study was to investigate if AICAR could inhibit the basal and the TNFα-induced CXCL8 secretion in normal human thyroid cells (NHT) and in thyroid cancer cell lines TPC-1 and BCPAP (RET/PTC and BRAFV600e mutated, respectively). The effect of AICAR on basal and CXCL8-induced cell migration was assessed. Cells were incubated with AICAR (0.05, 0.5, 1, 2 mM) alone or in combination with TNF-α (10 ng/ml) for 24 h. CXCL8 concentrations were measured in cell supernatants. Transwell migration assays were performed in NHT, TPC-1 and BCPAP, basally and after treatment with AICAR (2 mM) and rh-CXCL8 (50 ng/ml) alone or in combination. AICAR dose dependently inhibited the basal secretion of CXCL8 in TPC-1 (F = 4.26; p
