“…More recently, elevated plasma level of MMP9 is proved to be valuable to identify metastatic phenotype and as treatment monitor in patients with OSCC (Patel, Shah, Shukla, Shah, & Patel, 2007). Additionally, up-regulated MMP3 has been identified to play a potential role in the pathogenesis of OSCC and activated MMP3 might contribute to regulate angiogenesis that is a key process of tumor metastasis (Andisheh-Tadbir et al, 2014). Consistent with previous studies, result of function enrichment in the present study demonstrated that the three MMPs were involved in tumor metastasis of OSCC.…”
