Abstract:
Metalloproteinases (MMPs) play a significant role in vascular remodeling, and they have been suspected to be partly responsible for the pathogenesis of cardiovascular disease. Metalloproteinases have been reported to be increased in atherosclerosis and type 2 diabetes mellitus; however, so far they have not been evaluated in metabolic syndrome (MetS). Plasma activity of MMP-2 and MMP-9, high-sensitivity C-reactive protein concentration, dense low-density lipoprotein, and insulin-resistance markers were measured in 38 nondiabetic women with (n = 19) and without (n = 19) MetS. Women with MetS had significantly higher plasma activity of MMP-2 than controls (median [range], 1.3 [0.4-3.1] vs 0.7 [0.1-1.9]; P = .001). MMP-2 activity positively correlated with waist, homeostasis model assessment, and high-sensitivity C-reactive protein (P < .02) as well as with apolipoprotein B, dense low-density lipoprotein, triglycerides/high-density lipoprotein cholesterol index (P < .001) and negatively with high-density lipoprotein cholesterol (P < .002). Our finding of increased plasma activity of MMP-2 in women with MetS is important because they fit in with an early stage of cardiovascular disease; and measurement of soluble molecules may improve the risk assessment, early diagnosis, and prognosis of cardiovascular disease.
Insights
Metabolic syndrome (MetS) is linked to increased matrix metalloproteinase-2 (MMP-2) activity. This finding suggests MMP-2 may play a role in the early stages of cardiovascular disease in women with MetS.
Area of Science:
- Cardiovascular disease research
- Biomarkers in metabolic disorders
Background:
- Matrix metalloproteinases (MMPs) are implicated in vascular remodeling and cardiovascular disease pathogenesis.
- Elevated MMPs are observed in atherosclerosis and type 2 diabetes mellitus.
- MMPs have not been previously evaluated in the context of metabolic syndrome (MetS).
Purpose of the Study:
- To investigate plasma activity of MMP-2 and MMP-9 in women with and without MetS.
- To explore correlations between MMP activity and metabolic and cardiovascular risk factors.
Main Methods:
- Plasma MMP-2 and MMP-9 activity, high-sensitivity C-reactive protein, dense low-density lipoprotein, and insulin resistance markers were measured.
- A cohort of 38 non-diabetic women, with (n=19) and without (n=19) MetS, was studied.
Main Results:
- Women with MetS exhibited significantly higher plasma MMP-2 activity compared to controls (P = .001).
- MMP-2 activity positively correlated with waist circumference, homeostasis model assessment, high-sensitivity C-reactive protein, apolipoprotein B, dense LDL, and TG/HDL-C index.
- MMP-2 activity showed a negative correlation with high-density lipoprotein cholesterol (P < .002).
Conclusions:
- Increased plasma MMP-2 activity in women with MetS suggests its involvement in early cardiovascular disease stages.
- Measurement of soluble molecules like MMP-2 may enhance cardiovascular disease risk assessment, early diagnosis, and prognosis.
