Abstract

Aberrant activity of transcription factors in oral squamous cell carcinoma (OSCC) results in the spontaneous secretion of various cytokines and chemokines. Among them, IL-8, owing to its angiogenic activity, promotes the growth of OSCCs. In the present study, we examined the role of IL-8 secreted by OSCCs, on the angiogenic activity of monocytic THP1 cells. Culture supernatant (Ca-sup) augmented IL-8 secretion by THP1 cells, which was found to be significantly reduced following the removal Ca9-22-derived IL-8 from the Ca-sup. IL-8 induction was regulated at the transcriptional level, because real-time PCR demonstrated the augmented IL-8 messenger RNA (mRNA) expression. We further performed the luciferase assay using the 5′-untranslated region of IL-8 gene. Contradictory to our speculations, luciferase activity was not augmented by Ca-sup stimulation. NF-κB-independent IL-8 induction was further confirmed by pre-treating THP1 cells with NF-κB-specific inhibitors. To elucidate the signaling pathway, THP1 was pre-treated with MEK inhibitors. The results demonstrated that pre-treatment of cells with MEK inhibitor drastically reduced IL-8 levels, suggesting the role of MEK. Moreover, Ca-sup was found to increase ERK1/2 phosphorylation in a time-dependent manner. These results indicated that OSCC-derived IL-8 appears to activate angiogenic activity in monocytes within the tumor microenvironment via the mitogen-activated protein kinase (MAPK) pathway.
