Positive association of MMP 14 gene polymorphism with vulnerable carotid plaque formation in a Han Chinese population

2014 
AbstractBackground. MMP 14 is expressed in atherosclerotic plaques and potentially plays an important role in the development of vulnerable carotid plaques. MMP 14 gene polymorphisms can influence the bioactivity or expression of MMP 14. Objective. The aim of this study was to investigate the association between MMP 14 position + 7096 T > C (NM_004995.2:c.855T> C, rs2236307) polymorphism and vulnerable carotid plaque formation. Methods. 1370 patients with ischemic cerebral infarctions were enrolled and divided into three groups according to their carotid ultrasound examination: No plaque group (n = 346), stable plaque group (n = 695) and vulnerable plaque group (n = 329). The traditional atherosclerosis risk factors were recorded, and the MMP 14 polymorphism were genotyped by Applied Biosystems 7300 Real-Time PCR System using the TaqMan assay. Results. In the multiple logistic regression analysis done among the sub-groups, compared to no carotid plaque group, individuals with the MMP 14 position + 7096 TC...
