Myeloid zinc finger 1 (MZF1) gene belongs to the Kruppel family of zinc finger transcription factors. MZF1 has been suggested to play an important role in the tumorigenesis, invasion, and apoptosis of various tumor cells. However, the role of MZF1 in human cervical cancer remains unclear. To investigate the molecular mechanisms of MZF1 and its functional role in human cervical cancer cell migration and invasion, we experimented on stable SiHa cells overexpressing MZF1. We found that MZF1 overexpression inhibits the migratory and invasive abilities of SiHa cervical cancer cells. In addition, the overexpression of MZF1 significantly reduces MMP-2 protein and mRNA levels. Luciferase and ChIP assays suggested that MZF1 directly binds to MMP-2 gene regulatory sequences in vivo and suppresses MMP-2 promoter activity in vitro. This study shows that MZF-1 represses MMP-2 transcription and suggests that this repression may be linked to inhibition of human cervical cancer cell migration and metastasis. (c) 2012 Elsevier Inc.
