Association between matrix-metalloproteinase polymorphisms and prostate cancer risk: a meta-analysis and systematic review

Matrix metalloproteinases targeting in prostate cancer

Prostate cancer (PCa) is one of the most common tumors affecting men all over the world. PCa has brought a huge health burden to men around the world, especially for elderly men, but its pathogenesis is unclear. In prostate cancer, epigenetic inheritance plays an important role in the development, progression, and metastasis of the disease. An important role in cancer invasion and metastasis is played by matrix metalloproteinases (MMPs), zinc-dependent proteases that break down extracellular matrix. We review two important forms of epigenetic modification and the role of matrix metalloproteinases in tumor regulation, both of which may be of significant value as novel biomarkers for early diagnosis and prognosis monitoring. The author considers that both mechanisms have promising therapeutic applications for therapeutic agent research in prostate cancer, but that efforts should be made to mitigate or eliminate the side effects of drug therapy in order to maximize quality of life of patients. The understanding of epigenetic modification, MMPs, and their inhibitors in the functional regulation of prostate cancer is gradually advancing, it will provide a new technical means for the prevention of prostate cancer, early diagnosis, androgen-independent prostate cancer treatment, and drug research.

Current evidence on the relationships among five polymorphisms in the matrix metalloproteinases genes and prostate cancer risk

Matrix metalloproteinases (MMPs) had a variety of subtypes, which may be related to tumor invasion and angiogenesis, and the polymorphisms from MMPs have been also associated with the susceptibility to a variety of tumors, including prostate cancer (PCa). However, previous studies have not systematically analyzed the association between MMP and prostate cancer, so we conducted systematic data collection and analyzed to evaluate the relationship among polymorphisms in MMPs and PCa susceptibility. We searched PubMed, Web of Science, Embase and Google Scholar for all papers published up to Apr 3rd, 2023, and systematically analyzed the relationship among MMP1-1607 2G/1G, MMP2-1306 T/C, MMP2-735 T/C, MMP7-181 G/A, MMP9-1562 T/C and PCa susceptibility using multiple comparative models and subgroup analyses. We found that MMP2-1306 T/C polymorphism showed associations with PCa susceptibility, with the Ethnicity subgroup (Asian) being more pronounced. Similarly, MMP9-1562 T/C has also had associations with PCa susceptibility. Our current study found that the polymorphisms of, MMP2-1306 T/C, and MMP9-1562 T/C had strong associations with PCa risk.

The Role of the Matrix Metalloproteinase-9 Gene in Tumor Development and Metastasis: A Narrative Review

Matrix metalloproteinase-9 (MMP-9) is one of the widely studied enzymes of the extracellular matrix which can degrade various matrix biomolecules. The gene coding for this enzyme has been found to be associated with various multifactorial diseases, including cancer. More specifically, the expression of MMP-9 and polymorphisms of its gene have been found to be correlated with the formation and the invasiveness of different types of cancer. Hence, the latter gene can potentially be used both as a clinical genetic marker and a possible target in anticancer therapy. The present minireview explores the role of the MMP-9 gene in the process of tumor formation, growth, and metastasis and presents an overview of the polymorphisms of the gene associated with cancer as well as its regulation mechanisms, to provide an insight into the potential clinical applications. Nevertheless, further clinical trials and research are still required to reach more valuable conclusions for the clinical implications of the recent findings.

CD44 rs13347C>T Variants in 3'UTR and Prostate Neoplasms: A Case-control Study and Bioinformatics Approach

CD44, a cell-surface receptor and a key player in cellular signaling, can act as both tumor suppressor and promoter. This study aimed to investigate the association of CD44 rs13347C>T variants with prostate neoplasms, including both benign prostatic hyperplasia (BPH) and prostate cancers using a case-control and bioinformatics approach. Genomic DNA was extracted from 545 blood samples (225 BPH, 225 prostate cancers, and 95 control) and the CD44 rs13347C>T genotypes were identified using PCR-RFLP. We explored miRNA interactions using the miRNASNP-v3 database and GeneMANIA for co-expression networks. Results showed cancer patients had significantly higher PSA levels compared to both controls (p= 0.03) and BPH (p= 0.01). Additionally, digital rectal examination-positive and smoker BPH patients showed significantly the increased cancer risk (p= 0.004, p= 0.046). Prostate cancer group indicated significantly higher frequency of CD44 rs13347C>T mutant allele compared to control and BPH groups, particularly in TT and CT+TT genotypes (p < 0.05). miRNA SNP-v3 database predicted the mutant allele of CD44 rs13347C>T could lose 1 and gain 6 miRNAs for a new site created. Co-expression analysis revealed a direct interaction between CD44 and aryl hydrocarbon receptor (AHR), a gene known to be dysregulated in smokers. Furthermore, these genes alone display co-expression interactions with integrin subunit alpha 4 (ITGA4), protein plays a paradoxical role, both suppressing and promoting tumors. Based on the findings, the mutant allele of CD44 rs13347C>T may disrupt miRNA binding, which may potentially impact CD44, AHR, and ITGA4 expression in smokers, possibly contributing to prostate cancer progression.

Zinc in Prostate Health and Disease: A Mini Review

Introduction-With the high global prevalence of prostate cancer and associated mortalities, it is important to enhance current clinical practices for better prostate cancer outcomes. The current review is towards understanding the value of Zn towards this mission. Method-General information on Zn in biology and multiple aspects of Zn involvement in prostate health and disease were referred to in PubMed. Results-The most influential feature of Zn towards prostate health is its ability to retain sufficient citrate levels for a healthy prostate. Zn deficiencies were recorded in serum, hair, and prostate tissue of men with prostate cancer compared to non-cancer controls. Zn gut absorption, albumin binding, and storage compete with various factors. There are multiple associations of Zn cellular influx and efflux transporters, Zn finger proteins, matrix metalloproteinases, and Zn signaling with prostate cancer outcomes. Such Zn marker variations associated with prostate cancer recorded from biological matrices may improve algorithms for prostate cancer screening, prognosis, and management when coupled with standard clinical practices. Discussion-The influence of Zn in prostatic health and disease is multidimensional, therefore more personalized Zn requirements may be beneficial. Several opportunities exist to utilize and improve understanding of Zn associations with prostate health and disease.

Comprehensive bioinformatic analysis of MMP1 in hepatocellular carcinoma and establishment of relevant prognostic model

Matrix metalloproteinase 1 (MMP1) encodes endopeptidases associated with degradation of multiple components of the extracellular matrix. This function has increasingly been considered to play a major proteolysis role in tumor invasion and metastasis. However, the relationship between MMP1 gene expression, tumor-immune microenvironment and prognosis in hepatocellular carcinoma patients remains mostly unclear. This study focused on a comprehensive analysis of MMP1 in hepatocellular carcinoma, specifically the prognosis and tumor-immune microenvironment. MMP1 expression was analyzed using TCGA database and clinical samples. MMP1 associated mechanisms, pathways, mutations and prognosis in hepatocellular carcinoma were evaluated. We also analyzed the tumor-immune microenvironment and corresponding treatments. Our research demonstrated that MMP1 expression was upregulated in patients with hepatocellular carcinoma and correlated with poor survival. A prognostic model was established and its performance evaluated. We also found and report various correlations between MMP1 and immune-related cells/genes, as well the potential therapeutic agents. These findings indicate that MMP1 can potentially be a promising prognostic biomarker and indicator of the tumor-immune microenvironment status in hepatocellular carcinoma.

Recent advances in the application of metallomics in diagnosis and prognosis of human cancer

Metals play a critical role in human health and diseases. In recent years, metallomics has been introduced and extensively applied to investigate the distribution, regulation, function, and crosstalk of metal(loid) ions in various physiological and pathological processes. Based on high-throughput multielemental analytical techniques and bioinformatics methods, it is possible to elucidate the correlation between the metabolism and homeostasis of diverse metals and complex diseases, in particular for cancer. This review aims to provide an overview of recent progress made in the application of metallomics in cancer research. We mainly focuses on the studies about metallomic profiling of different human biological samples for several major types of cancer, which reveal distinct and dynamic patterns of metal ion contents and the potential benefits of using such information in the detection and prognosis of these malignancies. Elevated levels of copper appear to be a significant risk factor for various cancers, and each type of cancer has a unique distribution of metals in biofluids, hair/nails, and tumor-affected tissues. Furthermore, associations between genetic variations in representative metalloprotein genes and cancer susceptibility have also been demonstrated. Overall, metallomics not only offers a better understanding of the relationship between metal dyshomeostasis and the development of cancer but also facilitates the discovery of new diagnostic and prognostic markers for cancer translational medicine.

Investigation of the relationship between MMP-1 (- 1607 1G/2G), MMP-3 (- 1171 5A/6A) gene variations and development of bladder cancer

BACKGROUND

Chronic inflammation is an important risk factor in the development of bladder cancer. It may stimulate growth and metastasis of cancer cells. The inflammatory process includes MMP activities and expression. MMP activation can be stimulated by various inflammatory cells. Pathological processes such as bladder cancer may occur due to imbalance in MMP activities. In our study, we aimed to determine the relationship between MMP-1, MMP-3 gene variations associated with chronic inflammation and the bladder cancer development.

METHODS

Our study was carried out with 89 bladder cancer patients and 78 healthy controls. PCR-RFLP methods were applied to determine MMP-1 and MMP-3 gene variations genotype distributions.

RESULTS

1G/1G homozygous and 1G/2G heterozygous genotypes of MMP-1 gene variation were determined more in patients than controls. The 5A/5A homozygous and 5A/6A heterozygous genotypes of the MMP-3 gene variation were detected more in patients than controls. The significant difference was detected in terms of genotype distributions of MMP-1 and MMP-3 gene variations between these groups (p < 0.05). In addition to, the most common haplotype in the patient group were detected as 1G/2G-5A/6A (20.22%).

CONCLUSION

In this study, MMP-1 and MMP-3 gene variations were determined as possible genetic risk factors for bladder cancer development in the Thrace population.

Regulatory mechanisms of heme regulatory protein BACH1: a potential therapeutic target for cancer

A limited number of overexpressed transcription factors are associated with cancer progression in many types of cancer. BTB and CNC homology 1 (BACH1) is the first mammalian heme-binding transcription factor that belongs to the basic region leucine zipper (bZIP) family and a member of CNC (cap 'n' collar). It forms heterodimers with the small musculoaponeurotic fibrosarcoma (MAF) proteins and stimulates or suppresses the expression of target genes under a very low intracellular heme concentration. It possesses a significant regulatory role in heme homeostasis, oxidative stress, cell cycle, apoptosis, angiogenesis, and cancer metastasis progression. This review discusses the current knowledge about how BACH1 regulates cancer metastasis in various types of cancer and other carcinogenic associated factors such as oxidative stress, cell cycle regulation, apoptosis, and angiogenesis. Overall, from the reported studies and outcomes, it could be realized that BACH1 is a potential pharmacological target for discovering new therapeutic anticancer drugs.

Contribution of Matrix Metalloproteinase-1 Genotypes to Colorectal Cancer in Taiwan

BACKGROUND/AIM

Matrix metalloproteinase-1 is responsible for extracellular matrix regulation, and its genetic role in colorectal cancer (CRC) is unclear. The aim of the study was to investigate the contribution of Matrix metalloproteinase-1 genotypes to CRC risk in Taiwan.

MATERIALS AND METHODS

A total of 362 cases and 362 controls were included and their MMP-1 -1607 (rs1799705) genotypes were examined. The environmental factors and clinical-pathological records were also analyzed.

RESULTS

The genotypic frequency of MMP-1 rs1799750 were different between the CRC and control groups (p for trend=0.0083). 1G/2G and 1G/1G were associated with lower risk (p=0.0438 and 0.0030, adjusted OR=0.73 and 0.54, 95%CI=0.54-0.90 and 0.37-0.83). Among non-smokers, those with 1G/2G and 1G/1G genotypes were at 0.70- and 0.48-fold odds of having CRC. Among non-alcohol drinkers, people with 1G/2G and 1G/1G genotypes were at 0.71- and 0.54-fold odds. The 1G/1G genotype were statistically lower among CRC patients with lymph node metastasis (7.2%) than those without (19.0%).

CONCLUSION

The genotypes at MMP-1 rs1799705 play a role in determining susceptibility to CRC risk in Taiwan.

Matrix metalloproteinase (MMP)-1 and MMP-3 gene variations affect MMP-1 and -3 serum concentration and associates with breast cancer

Matrix metallopeptidases (MMPs) 1 and 3 have been shown to contribute to the initiation, and progression of different cancers, including breast cancer (BC). In this study, we aimed to examine the relations between polymorphisms of MMP1 (rs1799750) and MMP3 (rs632478) and their circulating levels with BC. The polymorphisms were genotyped by PCR-based Restriction Fragment Length Polymorphism (RFLP) and Allele-Specific PCR (AS-PCR) among 100 patients and 100 controls. MMP1 and MMP3 serum levels were measured by enzyme-linked immunosorbent assay (ELISA). Genotype distributions of MMP1 and MMP3 genes showed significant difference between patients and controls. The distribution of 2G/2G, 1G/2G and 1G/1G genotypes for MMP1 was 74%, 2% and 24% in the patients and 38%, 2% and 60% in the controls, respectively (P = 0.0001). For MMP3 the distribution of C/C, A/C and A/A genotypes was 28%, 54% and 18% in patients and 48%, 40% and 12% in controls, respectively (P = 0.01). For MMP1, the 2G/2G genotype was linked with a higher risk of BC when compared with that of the 1G/1G genotype (OR = 4.86; 95% CI = 2.63-8.99; P = 0.0001). For MMP3, in co-dominant model, there was a higher risk of BC in A/A and A/C genotype carriers (A/A: OR = 2.57; 95% CI = 1.08-6.11; P = 0.03) (A/C: OR = 2.31 95% CI = 1.24-4.30; P = 0.008). We also showed that MMP1 and MMP3 serum level was significantly increased in BC patients compared to controls. MMP1 and MMP3 genetic variations and their circulating levels are both significantly related to BC.

Metalloproteinases and Their Inhibitors: Potential for the Development of New Therapeutics

The metalloproteinase (MP) family of zinc-dependent proteases, including matrix metalloproteinases (MMPs), a disintegrin and metalloproteases (ADAMs), and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTSs) plays a crucial role in the extracellular matrix (ECM) remodeling and degradation activities. A wide range of substrates of the MP family includes ECM components, chemokines, cell receptors, and growth factors. Metalloproteinases activities are tightly regulated by proteolytic activation and inhibition via their natural inhibitors, tissue inhibitors of metalloproteinases (TIMPs), and the imbalance of the activation and inhibition is responsible in progression or inhibition of several diseases, e.g., cancer, neurological disorders, and cardiovascular diseases. We provide an overview of the structure, function, and the multifaceted role of MMPs, ADAMs, and TIMPs in several diseases via their cellular functions such as proteolysis of other cell signaling factors, degradation and remodeling of the ECM, and other essential protease-independent interactions in the ECM. The significance of MP inhibitors targeting specific MMP or ADAMs with high selectivity is also discussed. Recent advances and techniques used in developing novel MP inhibitors and MP responsive drug delivery tools are also reviewed.

Serum Levels of Matrix Metalloproteinase-1 in Brazilian Patients with Benign Prostatic Hyperplasia or Prostate Cancer

Metalloproteinases (MMPs) are involved in metastatic tumor processes, with changes in circulating levels detected in several cancer types. Here, we compare serum concentrations of metalloproteinase-1 (MMP-1) across individuals clinically diagnosed with prostate cancer (PCa) or benign prostatic hyperplasia (BPH), correcting results for the rs495366 single nucleotide polymorphism (SNP) that predisposes to differential MMP-1 levels. 196 men aged ≥50 years were followed at a university hospital urology outpatient clinic, with clinical, anthropometric, and rectal examinations performed by one urologist. Blood samples obtained prior to any clinical intervention provided baseline MMP-1 and total/free PSA levels as well as metabolic, hormonal, and inflammatory markers. The SNP was genotyped by real-time PCR. Participants with medical and/or laboratory profile compatible with malignancy composed the PCa group when confirmed by the Gleason scale. As expected, A-allele homozygotes showed reduced levels of MMP-1. Genotype-adjusted analyses revealed the mean MMP-1 level as 2-fold higher in PCa carriers compared to BPH patients. No other differences were found according to the prostatic condition or genotypic distribution, except for the expected raise in total and free PSA levels in PCa. In conclusion, increased serum levels of MMP-1 were observed in this context of prostatic malignancy compared to a benign phenotype, regardless of a genetic influence.

Association between matrix metalloproteinase-9 gene polymorphism and breast cancer in Brazilian women

OBJECTIVE

This study aimed to determine the relationship between rs17576 (MMP-9) polymorphism and increased cancer risk in a Brazilian breast cancer cohort.

METHODS

This study included 141 women (71 breast cancer patients and 70 controls without breast cancer) who donated 3 mL of their peripheral blood for genomic DNA extraction. This DNA was then genotyped using a real-time polymerase chain reaction.

RESULTS

The AG (rs17576) genotype was identified in 26 (18.43%) participants in the case group and in 22 (15.60%) participants in the control group (p=0.274), while the GG genotype was identified in ten (7.09%) participants in the case group and in one (0.70%) participant in the control group (p<0.003 - OR (95% CI) 13.13 (1.73, 593.08). No significant difference in the incidence rates was observed for AG or GG rs17576 genotypes in premenopausal women, p=0.813 and p=0.556, respectively. However, in postmenopausal women, the AG genotype was shown to occur in 14 (22.5%) participants in the case group and in 4 (6.45%) participants in the control (p<0.043), while GG genotype occurred in eight (12.90%) of the individuals in the case group and in none of the individuals in the control group (p<0.006).

CONCLUSION

In this study, the MMP-9 rs17576 GG polymorphic variant was shown to be significantly associated with breast cancer risk in premenopausal women, while the AG and GG genotypes were associated with increased cancer risk in postmenopausal women.

Association of polymorphisms in IL-8, MMP-1 and MMP-13 with the risk and prognosis of oral and oropharyngeal squamous cell carcinoma

OBJECTIVE

This study investigated the risk and prognostic value of single nucleotide polymorphisms (SNP) inIL-8, MMP-1 and MMP-13 in oral and oropharyngeal squamous cell carcinomas (SCCs).

DESIGN

SNPs rs2227532 and rs4073 inIL-8, rs2071230 and rs470558 in MMP-1, and rs2252070 in MMP-13 were genotyped in 125 oral and oropharyngeal SCC patients and 130 healthy controls, using TaqMan allelic discrimination assays. Multiple logistic regression models were used to explore the association between SNPs and cancer development, as well as SNP-SNP interaction and gene-environmental factor (GxE) interaction. Univariate and multivariate methods were applied for survival analyses.

RESULTS

With exception of rs2227532, all the SNPs were in Hardy-Weinberg equilibrium in the control. No associations between rs4073 in IL-8 and rs2071230 and rs470558 in MMP-1 were observed, but rs2252070 in MMP-13, in the dominant model, was associated in a protective manner to oral and oropharyngeal SCC (OR: 0.20, 95% CI: 0.06-0.71, p = 0.007). All SNPs interact significantly with cigarette smoking and alcohol consumption on susceptibility to oral and oropharyngeal SCC, but they showed no influence on survival of the patients.

CONCLUSIONS

Our results show that rs2252070 inMMP-13 may confer protection effect against oral and oropharyngeal SCC. In addition, the combined effects of IL-8 (rs4073), MMP-1 (rs2071230 and rs470558) and MMP-13 (rs2252070) with environmental carcinogens, such as tobacco and alcohol, are related to increased risk for oral and oropharyngeal SCC development.
