OBJECTIVE: To investigate the relationship between the messenger RNA(mRNA) levels of matrix metalloproteinases(MMP-9, MMP-2) and tissue inhibitor of metalloproteinase (TIMP-1, TIMP-2) and malignant transformation of hydatidiform mole.
METHODS: Total RNA were isolated from tissues of 22 normal chorionic villi samples and 37 cases of hydatidiform mole. The mRNA expression of MMP-9, MMP-2, TIMP-1, TIMP-2 genes were determined by RT-PCR.
RESULTS: The differences of the mRNA expression of MMP-9, MMP-2, TIMP-1, TIMP-2 genes in the tissues of hydatidiform mole and normal preganacy villus were not significant (P > 0.05). The ratio of MMP-9/TIMP-1 in molar tissues with malignant transformation was higher than those in molar tissues without malignant transformation and in normal villus.
CONCLUSION: It is a correlative relation beween MMP-9/TIMP-1 and malignancy of hydatidiform mole. The ratio of MMP-9/TIMP-1 might be used as an index for prediction of malignant transformation of hydatidiform mole.
