Abstract
The current investigation aims to explore the relationship between matrix metalloproteinase-3 (MMP-3) gene polymorphism and ovarian cancer (OC) risk. Two hundred forty pathologically confirmed OC patients and 390 healthy controls participated in the present investigation. Polymerase chain reaction-restriction fragment length polymorphism was applied to investigate the present polymorphism. At the same time, the meta-analysis was also performed to comprehensively explore the relationship. Three genotypes (5A/5A, 5A/6A, and 6A/6A) were observed for MMP-3 gene polymorphism. 6A/6A genotype and 6A allele displayed significant increase in OC patients (all P < .05). Meta-analysis found that no significant results (all P > .05). In conclusion, our results indicate that MMP-3 gene polymorphism contributes increased risk to OC for southern Chinese population. And meta-analysis indicates that MMP-3 gene polymorphism contributes no risk to OC in other populations.
