Abstract
Background Many studies have investigated the association between matrix metalloproteinase polymorphisms and lung cancer susceptibility. However, the results are still controversial. To clarify these associations, we conducted a meta-analysis. Methods A systematic search of studies was conducted in PubMed, Embase, and China National Knowledge Infrastructure. Overall and subgroup analysis stratified by ethnicity was conducted. OR with 95% CI was used to assess the strength of the association. Furthermore, false-positive report probability (FPRP) tests were also performed for associations obtained in this meta-analysis. Results Twenty-four studies, including 10,099 cases and 9,395 controls, were analyzed. Nine polymorphisms were reported. For MMP1 -1607 1G/2G and MMP7 -181 A/G, increased lung cancer risk was found in Asians. For MMP2 -1306 C/T and MMP2 -735 C/T, decreased lung cancer risk was found in both “diverse populations” and Asians. For MMP9 -1562, C/T decreased lung cancer risk was found in both “diverse populations” and Caucasians. For MMP13 -77A/G, the A/G genotype decreased lung cancer risk in Asians. However, only associations between MMP1 -1607 1G/2G, MMP2 -1306 C/T, MMP2 -735 C/T, and MMP7 -181 A/G and lung cancer risk were considered noteworthy according to FPRP tests. There was no association between MMP3 -1171 5A/6A, MMP9 R279Q, and MMP12 -82A/G and lung cancer risk. Conclusions Our meta-analysis suggested that MMP1 -1607 1G/2G and MMP7 -181 A/G were risk factors for lung cancer, while MMP2 -1306 C/T, MMP2 -735 C/T, MMP9 -1562 C/T, and MMP13 -77A/G might be protective factors. However, results for MMP9 -1562 C/T and MMP13 -77A/G should be interpreted with caution due to the probability of false-positive reports.

Abstract
Matrix metalloproteinases-2 (MMP2) has been reported to be overexpressed in various types of cancer. However, the contribution of various genotypes of MMP2 to lung cancer is controversial and not yet been examined in Taiwan. Therefore, in the current study, we investigated the association of MMP2 genotypes with lung cancer risk among Taiwanese. In this hospital-based, case-control study, 358 lung cancer patients and 716 age- and gender-matched healthy controls were recruited, and the genotypic distributions of MMP2-1306 and MMP2- 735 were determined. Then, their association with lung cancer was evaluated, and their interaction with personal smoking status was also examined via stratification analysis. The results showed that the percentages of variant CT and TT at MMP2-1306 were 17.3% and 1.7% among the lung cancer patients, respectively, much lower than those of 28.7% and 2.4%, respectively, among the healthy controls (P for trend = 0.0001). The allelic frequency distribution analysis showed that the variant T allele at MMP2-1306 conferred a statistically significantly lower lung cancer risk than the wild-type C allele (adjusted odds ratio = 0.54, 95% confidence interval = 0.41-0.72, P = 0.0001). There was an obvious effect of MMP2-1306 genotype on lung cancer risk among the subpopulations of ever smokers but not nonsmokers. As for the genotypes of MMP2-735, there was no such differential distribution in the aspects of genotypic or allelic frequencies, or combinative effects with smoking status. The genotypes of MMP2-1306 may act as a biomarker in determining personal susceptibility to lung cancer in Taiwan. The contribution of MMP2 genotypes alone and its joint effects with personal cigarette smoking habit on lung cancer susceptibility should be taken into consideration of the clinical practices for early detection and prediction of lung cancer in Taiwan.

Abstract
Matrix metalloproteinase-2 (MMP2) is an endopeptidase, mainly responsible for degradation of extracellular matrix components, which plays an important role in cancer disease. A single nucleotide polymorphism (SNP) at -1306 disrupts a Sp1-type promoter site. The results from the published studies on the association between MMP2 -1306 C>T polymorphism and cancer risk are contradictory and inconclusive. In the present study, a meta-analysis was therefore performed to evaluate the strength of any association between the MMP2 -1306 C>T polymorphism and risk of cancer. We searched all eligible studies published on association between MMP2 -1306 C>T polymorphism and cancer risk in PubMed (Medline), EMBASE and Google Scholar online web databases until December 2013. Genotype distribution data were collected to calculate the pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) to examine the strength of the association. A total of 8,590 cancer cases and 9,601 controls were included from twenty nine eligible case control studies. Overall pooled analysis suggested significantly reduced risk associated with heterozygous genotype (CT vs CC: OR=0.758, 95%CI=0.637 to 0.902, p=0.002) and dominant model (TT+CT vs CC: OR=0.816, 95%CI=0.678 to 0.982, p=0.032) genetic models. However, allelic (T vs C: OR=0.882, 95%CI=0.738 to 1.055, p=0.169), homozygous (TT vs CC: OR=1.185, 95%CI=0.825 to 1.700, p=0.358) and recessive (TT vs CC+CT: OR=1.268, 95%CI=0.897 to 1.793, p=0.179) models did not show any risk. No evidence of publication bias was detected during the analysis. The results of present meta-analysis suggest that the MMP2 -1306 C>T polymorphism is significantly associated with reduced risk of cancer. However, further studies with consideration of different populations will be required to evaluate this relationship in more detail.

Abstract
AIM OF THE STUDY Matrix metalloproteinases (MMPs) are a zinc-dependant endopeptidase family that can degrade extracellular matrix components. Their dysregulation has been proven in several diseases, including cancer. Genetic variations in MMP promoter regions can alter their expression. The aim of the present study is to investigate the correlation of MMP-2 (-1306C/T), MMP-9 (-1562C/T), and MMP-12 (-82A/G) single nucleotide polymorphisms (SNPs) with oesophageal squamous cell carcinoma (ESCC) initiation and progression susceptibility in Iranian patients. MATERIAL AND METHODS MMP-2 (-1306C/T), MMP-9 (-1562C/T), and MMP-12 (-82A/G) SNPs were detected using polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) technique in 70 patients and 60 healthy controls. The genotypes and allele distributions were statistically compared in patients and controls. The correlation of MMP-2 (-1306C/T) and MMP-9 (-1562C/T) polymorphisms with clinicopathological features were investigated in 53 patients. RESULTS No statistically significant differences were observed in genotype and allele frequencies of MMP-2 (-1306C/T) and MMP-9 (-1562C/T) between patients and controls (p > 0.05). In addition, no relevance was observed in MMP-2 (-1306C/T) and MMP-9 (-1562C/T) SNPs and clinicopathological features. There was no nucleotide variation in MMP-12 (-82) in the case and control groups. CONCLUSIONS This study indicates that these three SNPs may have no significant association in ESCC risk in Iranian patients.

Abstract
Many studies have reported the association between the matrix metalloproteinase (MMP) polymorphisms and lung cancer susceptibility, but the results were inconclusive. We conducted a meta-analysis, using a comprehensive strategy based on the logistic regression and a model-free approach, to derive a more precise estimation of the relationship between MMP1, MMP2, MMP9 and MMP13 polymorphisms with lung cancer risk. A total of 22 case-control studies including 8202 cases and 7578 controls were included in this meta-analysis. For MMP1-1607 1G/2G, increased lung cancer risk was found among Asians in additive model(OR = 1.34, 95%CI:1.18-1.53) and with model-free approach(ORG = 1.41, 95%CI:1.21-1.65). For MMP2-1306 C/T and -735 C/T, based on the model-free approach, a significantly reduced risk was found in Asians(MMP2-1306 C/T:ORG = 0.49,95%CI:0.42-0.57; MMP2-735 C/T: ORG = 0.71, 95%CI:0.61-0.84). For MMP9-1562 C/T, a significantly increased risk was found among Asians(OR = 2.73, 95%CI:1.74-4.27) with model-free approach. For MMP13-77A/G, there was no association between this polymorphism and lung cancer risk in the recessive model(OR = 1.02, 95%CI:0.83-1.26) and with the model-free approach(ORG = 0.95, 95%CI:0.76-1.17). Therefore, this meta-analysis suggests that the MMP1-1607 1G/2G, MMP2-1306 C/T, MMP2-735 C/T, MMP9 -1562 C/T polymorphisms were risk factors for lung cancer among Asians, while MMP13 -77A/G polymorphism was not associated with lung cancer risk.

Abstract
AIM The aim of this study was to investigate the polymorphism frequency of plasminogen activator inhibitor-1 (PAI-1) (rs1799889) 4G/5G in patients with lung cancer. METHODS In this study, 286 genomic DNAs (154 lung cancer patients+132 subjects without lung cancer) were analyzed. Polymorphisms were determined by using the polymerase chain reaction (PCR) method, with 4G and 5G allele-specific primers. PCR products were assessed by a charge-coupled device camera and exposed to 2% agarose gel electrophoresis. RESULTS The frequencies of the PAI-1 gene 4G/5G genotypes were found to be 21% 4G/4G, 16% 4G/5G, and 62% 5G/5G in the control group and 31.4% 4G/4G, 30.8% 4G/5G, and 37.8% 5G/5G in the patient group. It was determined that the 5G/5G genotype frequency was high in patients in comparison with other genotypes. CONCLUSIONS This study found a statistically significant difference between the groups with respect to genotype distribution. Consequently, we can say that the PAI-1 gene 4G/5G polymorphism is associated with lung cancer in Turkey.

Abstract
The current study was conducted to determine whether there is a relation between hypertension and two different polymorphisms, including C1562T of the Matrix metalloproteinase-9 (MMP-9) gene and C677T of the methylenetetrahydrofolate reductase (MTHFR) gene. Genomic DNA obtained from 224 persons (125 patients with hypertension and 99 healthy controls) were used in the study. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism and electrophoresis. The results were statistically analyzed and were found to be statistically significant. The frequencies of the C1562T genotypes were found to be, in controls CC 75.8 % and CT 24.2 % and in patients CC 71.2 %, and CT 28.8 %. The frequencies of C677T genotype were found to be, in controls CC 56.6 %, CT 38.4 and TT 5.1 % in controls and in patients CC 52 %, CT 30.4 % and TT 17.6 %. In conclusion, we may suggest that there is no relation between the essential hypertension and C1562T polymorphism of MMP-9 gene; on the other hand C677T polymorphism (genotype TT) of MTHFR gene can be regarded as a genetic indicator for the development of essential hypertension.

Abstract
BACKGROUND Previous studies assessing associations between matrix metalloproteinase 2 (MMP-2) polymorphisms and lung cancer risk reported conflicting results. A meta-analysis was therefore performed to derive a more precise estimation. METHOD Case-control studies assessing associations between MMP-2 C735T and C1306T polymorphisms and lung cancer risk were included. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated. RESULTS 7 studies with a total of 3,189 lung cancer cases and 3,013 controls were finally included into this meta-analysis. Overall, the MMP-2 C735T polymorphism was associated with lung cancer risk under the homozygote model (CC versus TT: OR =1.44, 95% CI = 1.03-2.02, I2 = 0%), while the MMP- 2 C1306T polymorphism also associated demonstrated links with all four models (all P values less than 0.05). Subgroup analyses by race suggested obvious associations between MMP-2 C735T and C1306T polymorphisms and lung cancer risk in Asians but not in Caucasians. There was no evidence for publication bias. CONCLUSION Currently available evidence supports teh conclusion that MMP-2 C735T and C1306T polymorphisms influence susceptibility to lung cancer in Asians.

Abstract
PURPOSE Matrix metalloproteinase (MMP) 1, MMP2, MMP3 and MMP9 are important members of the MMP family. Recently, many studies have been carried out on the association between polymorphisms of MMP1-1607 1G/2G, MMP2-735 C/T, MMP2-1306 C/T, MMP3-1171 5A/6A and MMP9-1562 C/T and lung cancer risk. However the results of these studies remained inconclusive due to conflicting results from different case-control studies. To clarify these associations, we conducted a meta-analysis. METHODS We conducted a comprehensive search in Medline, EMBASE, OVID and Chinese Biomedical Literature Database (date from Jan 2000 to Aug 2012). Overall and subgroup analysis by the ethnicity of study population was carried out. Odds ratio (OR) with 95% confidence interval (95%CI) was used to assess the strength of the association. RESULTS There were 17 studies involving five polymorphic sites in four MMP genes. For MMP1-1607,increased lung cancer risk was found under dominant model (MMP1-1607 1G/2G: OR=1.14, 95%CI=1.03-1.26, P=0.01), but not in the Caucasian population. For MMP2-1306 C/T, T polymorphism decreased lung cancer risk under dominant and recessive models (dominant, OR=0.63, 95%CI=0.46-0.88, P=0.0006; recessive, OR=0.61, 95%CI=0.38-0.99, P=0.04). For MMP9-1562 C/T, TT genotype decreased this risk under the recessive model (OR=0.38, 95%CI=0.19-0.75, P=0.005), but not in the Asian population. For MMP2-735 C/T and MMP3-1171 5A/6A, there was no association between this polymorphism and lung cancer risk under the dominant and recessive models. CONCLUSIONS MMP1-1607 1G/2G polymorphism increased lung cancer risk in Asians. It was also found that MMP2-1306 C/T polymorphism decreased lung cancer risk in Asians, while MMP9-1562 C/T polymorphism decreased lung cancer risk in Caucasians. No significant difference was found in any genotype of MMP2-735 C/T and MMP3-1171 5A/6A. Further studies with larger sample sizes should be carried out.

Abstract
BACKGROUND Genetic factors contribute to the increasing incidence of childhood asthma. The ADAM33 (a disintegrin and metalloprotease domain-containing protein 33) gene, discovered through positional cloning, is the first to be associated with asthma and bronchial hyperresponsiveness. This case-control study conducted in a Han Chinese population in northern China compared the genotypes of child asthmatic patients to healthy controls for the presence of 6 single nucleotide polymorphisms (SNPs) in the ADAM33 gene. METHODS The study population was composed of 412 children with asthma and 397 healthy controls. We genotyped 6 SNPs (F+1, T+1, T2, T1, V4, and Q-1) of ADAM33 with the PCR-restriction fragment length polymorphism (PCR-RFLP) method. Data were statistically analyzed to determine if an association existed between these genotypes and childhood asthma morbidity. RESULTS Three SNPs (T+1, T1, and V4) and 4 haplotypes (H1, H3, H5, and H8) were strongly associated with childhood asthma in children of northern China compared to healthy controls (P<0.05), whereas the other tested SNPs and haplotypes demonstrated no significant relationship. CONCLUSION The ADAM33 gene plays an important role in facilitating susceptibility to childhood asthma in this Han Chinese population.

Abstract
The Matrix metalloproteinase-9 functional promoter polymorphism 1562C>T may be considered an important genetic determinant of early-onset coronary artery disease (ECAD). In this study, association between MMP-9 1562C>T allele with plasma MMP-9 activity, homocysteine and lipid-lipoproteins level and ECAD in Iranian subjects was investigated. This case-control study consisted of 53 ECAD patients (age < 55 years) and unrelated late-onsets CAD (age>70 years) who angiographically had at least 50% stenosis. MMP-9 1562C>T polymorphism was detected by PCRRFLP, plasma MMP-9 activity, serum lipid and homocysteine levels were determined by gelatin gel zymography, enzyme assay and by HPLC, respectively. The presence of MMP-9 1562C>T allele was found to be associated with ECAD (OR=3.2, P=0.001). The ECAD patients with MMP-9 1562C>T allele had higher MMP-9 activity (P=0.001), LDL-C (P=0.045), TC (P=0.02) and homocysteine (P=0.01) levels than the LCAD subjects. MMP-9 1562C>T allele is a risk factor for ECAD. The carriers of this allele have high levels of MMP-9 activity, LDL-C, TC and homocysteine (P=0.01), thus, are more likely to develop myocardial infarction and CAD at young age (less than 55 years).

Abstract
Lung cancer is the most common cause of cancer death worldwide. Smoking is known as the strongest single factor in the development of lung cancer. However, there are inherited genetic factors that cause different responses to cigarette smoking exposure among individuals. We tried to identify these differences in heavy smokers by examining copy number variations (CNVs) between lung cancer patients and healthy controls. Analysis by array comparative genomic hybridization which was tested with 20-person training set (10 lung cancer patients, 10 healthy controls) showed 26 significant (adjusted P < 0.05) clones with either copy number gains or losses. Three genes, KCTD11, FGF11, and PTPRH on chromosomal regions 17p13.1 (KCTD11 and FGF11) and 19q13.42 (PTPRH), were selected (adjusted P < 0.001) and tested by real-time quantitative PCR with 34 healthy controls and 54 lung cancer patients. KCTD11 on the chromosomal region 17p13.1 showed significant high odds ratio (OR = 16.0) in heavy smokers, implying that this is a susceptibility region for lung cancer in this group. Therefore, CNVs of 17p13.1 is a promising candidate to identify individuals with a high genetic risk for the development of lung cancer.
