Objectives:
The objective of this study was to explore the role and mechanism of an abnormally expressed circRNA (hsa_circ_0009128) in the progression of oral squamous cell carcinoma.
Materials And Methods:
We conducted quantitative real-time PCR (qRT-PCR) to assess the expression of hsa_circ_0009128 in 51 paired OSCC tissues and analyzed the correlation between clinical features and aberrant expression of hsa_circ_0009128 in OSCC. CCK-8 assays, colony formation assays, transwell assays, and wound healing assays were used to analyze the effect of hsa_circ_0009128 on cell proliferation and migration. Furthermore, epithelial-mesenchymal transition (EMT)-related proteins were evaluated by Western blotting.
Results:
Hsa_circ_0009128 was upregulated in both OSCC tissues and cell lines, and high hsa_circ_0009128 correlated with advanced TNM stage (p = 0.046) and lymph node metastasis (p = 0.018) in OSCC patients. Knockdown of hsa_circ_0009128 inhibited cell proliferation and migration. Mechanistically, hsa_circ_0009128 downregulation decreased EMT in OSCC cells as shown by elevated levels of E-cadherin and decreased N-cadherin, vimentin, and MMP9.
Conclusions:
The circRNA hsa_circ_0009128 correlates with malignant progression of OSCC. Hsa_circ_0009128 stimulates proliferation and migration in OSCC cells by targeting MMP9 to activate EMT.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
