Matrix Metalloproteinase-9 (MMP-9) Gene Polymorphism in Stroke Patients.

ABSTRACT: Matrix metalloproteinases (MMPs), endopeptidases degrading extracellular matrix, play an important role in the pathogenesis of atherosclerosis and vascular disease. The aim of this study was to evaluate the association between the C(-1562)T functional polymorphism in the MMP-9 gene and risk of stroke. We examined 322 patients with stroke and 410 controls. In the patient group, 52 % had type 2 diabetes. All subjects were genotyped for the C(-1562)T polymorphism by polymerase chain reaction and restriction analysis. A significant increase in T allele and CT + TT genotype frequencies was observed in patients compared with controls (OR 1.73, 95 % CI 1.34-2.23 and 1.89, 95 % CI 1.39-2.56, respectively). The T allele carriers were younger at the onset of stroke (63.5 ± 11.7 years) than patients with CC genotype (71 ± 14.1 years) (p = 0.0002). The comparison between patients with T2DM and without it showed that the T allele and CT + TT genotype were more frequent in T2DM patients (OR 1.48, 95 % CI 1.03-2.12 for T allele and 1.44, 95 % CI 1.93-2.24 for CT + TT genotype). In conclusion, our findings suggest that MMP-9 C(-1562)T polymorphism is significantly associated with risk of stroke in patients with and without T2DM.

Project description:ContextThe exact factors that determine the biological behavior of odontogenic lesions have not been thoroughly established yet. The influence of the matrix metalloproteinases (MMPs) on the clinical behavior of these lesions was recently brought to light.AimsWe did a pioneer study to investigate the association of MMP9 (rs3918242 [-1562 C/T] and rs17576) and MMP2 (rs243865 [-1306 C/T] and rs865094) gene polymorphisms and aggressiveness of ameloblastomas, keratocystic odontogenic tumors (KCOT) and dentigerous cysts (DC).Settings and designA case-control study conducted in the Department of Oral Pathology and Microbiology, Government Dental College, Trivandrum and Human Molecular Genetics Laboratory, Rajiv Gandhi Institute of Biotechnology and Poojappura, Trivandrum, Kerala.Subjects and methodsDNA from the blood samples of histopathologically proven ameloblastoma (n = 15), KCOT (n = 11) and DC (n = 13) patients were extracted using standard protocols. Primers were designed based on the functionality and relevance for polymerase chain reaction (PCR). PCR products were analyzed by PCR-restriction fragment length polymorphism and sequencing.Statistical analysis usedChi-square analysis was done to assess the association of gene polymorphisms among the cases and controls.ResultsAmeloblastomas showed a higher frequency of mutant allele (T = 0.43; P = 0.05) of MMP9 rs3918242 (-1562C/T) compared to the control population. All the cases showed a statistically significant difference in the distribution of genotype (P = 0.046) and allele (P = 0.03; odds ratio [OR] = 2.06 [1.08-3.95]) frequency of MMP2 rs2438659 (-1306C/T). KCOT samples also showed a significant association in distribution of both genotype (P = 0.01) and allele (P = 0.01 with an OR at 3.42 [1.31-8.92]) frequency, on comparison with control population.ConclusionsMMP2 rs243865 polymorphism has a plausible role in increasing the aggressiveness of ameloblastomas and KCOT compared to that of the control population. Furthermore, MMP9 rs3918242 polymorphism may contribute to the aggressive behavior of ameloblastomas.
