Abstract(s) :

(Anglais) Recent clinical observations and experimental studies of our group indicate that macrophage migration inhibitory factor (MIF) may contribute to tumor progression in head and neck squamous cell carcinomas (HNSCC). The present study was undertaken to examine the effects of the irreversible MIF inhibitor 4-iodo-6-phenylpyrimidine (4-IPP) on proliferation and invasiveness of the squamous carcinoma cell line SCCVII. Cell counting, crystal violet assay and flow cytometry were used to analyze the effects of 4-IPP on SCCVII cell growth. The impact of 4-IPP on cell invasiveness was assessed by Boyden chamber assay. Knockdown of the MIF receptor CD74 was achieved by transduction with lentiviral vectors encoding anti-CD74 shRNAs. As shown by immunofluorescence staining, SCCVII cells express both MIF and CD74. Decreased MIF immunoreactivity as a result of exposure to 4-IPP suggested a covalent modification of the cytokine. 4-IPP inhibited SCCVII cell proliferation and invasiveness. Moreover, the cytostatic effect of 4-IPP was enhanced by CD74 knockdown. The inhibitory effects of 4-IPP on cell proliferation and invasiveness strongly suggest that MIF is involved in proliferative activity and invasive properties of squamous carcinoma cells. In conclusion, MIF inhibition may open possibilities for target-directed treatment of head and neck squamous cell carcinoma
