Expressions of matrix metalloproteinase 8 mRNA in apical granuloma and periapical cyst and their significances / 吉林大学学报(医学版)

ABSTRACT

Objective To discuss the role of matrix metalloproteinase-8(MMP-8) mRNA in apical granuloma and periapical cyst by detecting the its expressions in the periapical granuloma and periapical cyst.Methods Reverse transcription polymerase chain reaction(RT-PCR) technique was used to measure the expressions of MMP-8 mRNA in 22 cases of periapical granuloma,11 cases of periapical cyst and 10 cases of normal periapical tissues.Results The positive rates and the levels of MMP-8 mRNA expression in apical granulomas and periapical cysts were significantly higher than those in normal tissues(P0.05).Conclusion The expression of MMP-8 may play an important role in the pathogenesy of apical granuloma and periapical cyst,and it may be involved in the process of bone destruction.
