MMP14 not only promotes cell migration, invasion, and angiogenesis in nasopharyngeal carcinoma (Yan et al., 2015) and pituitary adenomas (Hui et al., 2015) but also promotes the secretion of pro-MMP2 and pro-MMP9 (Zarrabi et al., 2011). The gene discussed is MMP2; the disease is nasopharyngeal carcinoma.
