MMP2 and nasopharyngeal carcinoma: The upregulation of miR-124 has also been associated with reduced proliferation, migration, and invasion of nasopharyngeal carcinoma cells (C666-1 cells) via downregulation of STAT3, p-STAT3, G1/S-specific cyclin-D2 (CCND2) and Matrix Metalloproteinase-2 (MMP-2) expression in C666-1 cells (17).
