Background/Aims: Slug protein, a transcription factor for the induction of epithelial-mesenchymal transition (EMT) and cancer cell invasion and metastasis, is frequently upregulated in human epithelial cancers. However, mutation of this gene in cancer is rare, and the mechanism of its dysregulation remains unknown, especially in head and neck squamous cell carcinoma (HNSCC). Methods: We examined the role of TNF-α in the stabilization of Slug by immunoprecipitation-westernblot analysis. Migration of HNSCC cells with or without knockdown of Slug gene expression was assayed by a wound healing assay. Immunohistochemical staining analysis was used to measurement Slug levels in both normal and HNSCC tumor tissues. Results: The inflammatory cytokine TNF-α stabilized Slug protein by inhibiting its ubiquitination through the NF-κB pathway. Inhibition of NF-κB or knockdown of p65 abrogated the TNF-α-induced stabilization of Slug. Knockdown of Slug expression inhibited cancer cell migration and EMT characteristics induced by TNF-α. Moreover, increased levels of Slug were found to correlate with lymph node metastasis and predict poor prognosis in patients with HNSCC. Conclusions: NF-κB-mediated stabilization of Slug underlies the inflammation-induced EMT and metastasis in HNSCC, which may serve as a therapeutic target for metastatic HNSCC.

Underlying Mechanisms

Head and neck squamous cell carcinoma (HNSCC) affects 650,000 people worldwide and has a dismal 50% 5-year survival rate. Recurrence and metastasis are believed the two most important factors causing this high mortality. Understanding the biological process and the underlying mechanisms of recurrence and metastasis is critical to develop novel and effective treatment, which is expected to improve patients’ survival of HNSCC. MicroRNAs are small, non-coding nucleotides that regulate gene expression at the transcriptional and post-transcriptional level. Oncogenic and tumor-suppressive microRNAs have shown to regulate nearly every step of recurrence and metastasis, ranging from migration and invasion, epithelial-mesenchymal transition (EMT), anoikis, to gain of cancer stem cell property. This review encompasses an overview of microRNAs involved in these processes. The recent advances of utilizing microRNA as biomarkers and targets for treatment, particularly on controlling recurrence and metastasis are also reviewed.
