Association of uPA and PAI-1 tumor levels and 4G/5G variants of PAI-1 gene with disease outcome in luminal HER2-negative node-negative breast cancer patients treated with adjuvant endocrine therapy. BMC Cancer 2019; 19:71. [PMID: 30646864 PMCID: PMC6332605 DOI: 10.1186/s12885-018-5255-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2017] [Accepted: 12/27/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The aim of this study was to evaluate the prognostic potential of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor type 1 (PAI-1) tumor tissue levels and examine the association between these biomarkers and classical prognostic factors in early node-negative luminal breast cancer patients. The clinical value of 4G/5G variants of PAI-1 gene was evaluated. PATIENTS AND METHODS This study involved 81 node-negative, estrogen receptor-positive and/or progesterone receptor-positive and human epidermal growth factor receptor 2-negative operable breast cancer patients who underwent radical surgical resection and received adjuvant endocrine therapy. Determination of uPA and PAI-1 concentrations in the breast cancer tissue extracts was performed using FEMTELLE® uPA/PAI-1 ELISA. An insertion (5G)/deletion (4G) polymorphism at position - 675 of the PAI-1 gene was detected by PCR-RFLP analysis. RESULTS Our research showed that patients with uPA tumor tissue levels higher than 3 ng/mg of protein had significantly reduced disease-free survival (DFS) and overall survival (OS) when compared to patients with uPA tumor tissue levels lower or equal to 3 ng/mg of protein. Patients with PAI-1 tumor tissue levels higher than 14 ng/mg of protein had significantly decreased OS in comparison with patients with PAI-1 tumor tissue levels lower or equal to 14 ng/mg of protein. ROC analysis confirmed the uPA and PAI-1 discriminative potential for the presence/absence of relevant events in these patients and resulted in higher cut-off values (5.65 ng/mg of protein for uPA and 27.10 ng/mg of protein for PAI-1) than standard reference cut-off values for both biomarkers. The prognostic importance of uPA and PAI-1 ROC cut-off values was confirmed by the impact of uPA higher than 5.65 ng/mg of protein and PAI-1 higher than 27.10 ng/mg of protein on poorer DFS, OS and event-free survival (EFS). We observed that patients with dominant allele in PAI-1 genotype (heterozygote and dominant homozygote, - 675 4G/5G and - 675 5G/5G) had significantly increased DFS, OS and EFS when compared with patients with recessive homozygote genotype (- 675 4G/4G). CONCLUSION Our study indicates that uPA and PAI-1 tumor tissue levels and 4G/5G variants of PAI-1 gene might be of prognostic significance in early node-negative luminal HER2-negative breast cancer patients treated with adjuvant endocrine therapy.

Abstract
Idiopathic granulomatous mastitis (IGM) is a rare and chronic inflammatory disorder. IGM mimics breast cancer regarding its clinical and radiological features. Etiology of IGM remains unclarified. Our patient was 37-year-old and 14 weeks pregnant. There was pain, redness and swelling in the right breast. The mass suggestive of malignancy was detected in sonography. Serum CA 125 and CA 15-3 levels were high. Genetic analysis was performed for the etiology. methylenetetrahydrofolate reductase (MTHFR) C 677 TT, β-fibrinogen-455 G>A, plasminogen activator inhibitor (PAI)-1 5 G/5 G, angiotensin-converting enzyme (ACE) I/D mutation was found. IGM was diagnosed by cor biopsy. An association was also reported between breast cancer and mutations in MTHFR-C 677 T, PAI-1, ACE genes. Genetic polymorphisms may involve in the development of IGM as it was seen in our case. Further studies should be conducted to better clarify this plausible association.

Abstract
In this study, we tested the hypothesis that single nucleotide polymorphisms (SNPs) of differentiation-associated human gene icb-1 (C1orf38) may be associated with ovarian cancer susceptibility. For this purpose, we compared the genotype and allele frequencies of the SNPs rs1467465 and rs12048235 in a group of 184 ovarian cancer patients with a control group of 184 age- and gender-matched women without any malignancy. Genotype-phenotype association revealed that A allele of SNP rs1467465 was more frequent in ovarian cancer patients than in the control group (0.40 vs. 0.33, OR 1.37, 95% CI 1.013-1.853, p = 0.04). After analysis of allele positivity we observed that A-positive genotypes were more frequent in the ovarian cancer group (0.65 vs. 0.53, OR 1.63, 95% CI 1.072-2.483, p = 0.02). Furthermore, the heterozygous genotype of rs1467465 was found to be more frequent in the patients group (0.50 vs. 0.41, OR 1.63, 95% CI 1.045-2.045, p = 0.03). No significant results were obtained with regard to SNP rs1204823. Our data suggest, that SNP rs1467465 of human gene icb-1 might affect susceptibility to ovarian cancer.

Abstract
BACKGROUND AND AIMS Plasminogen activator inhibitor type 1 (PAI-1) is associated with poor prognosis in breast cancer. Transcriptional expression of the PAI-1 can be controlled by PAI-1 promoter 4G/5G polymorphism. However, the significance of PAI-1 promoter 4G/5G polymorphism in breast cancer patients is contentious. To address this controversy, we conducted a meta-analysis for the relationships between PAI-1 promoter polymorphism and clinicopathological characteristics of breast cancer. METHODS Relevant published studies were identified using a search of PubMed, Embase, and the ISI Web of Science. The effect sizes of PAI-1 promoter 4G/5G polymorphism on breast cancer risk, lymph node metastasis, histologic grade, and overall survival were calculated by odds ratio (OR) or hazard ratio. The effect sizes were combined using a random-effects model. RESULTS Individuals with 4G/4G genotype had a higher risk of breast cancer than those with the combined 4G/5G and 5G/5G genotypes (OR = 1.388; p = 0.031). Breast cancer patients with the 5G/5G genotype displayed lymph node metastasis more than patients with either the combined other genotypes (OR = 1.495; p = 0.027) or with the 4G/4G genotype (OR = 1.623; p = 0.018). However, the PAI-1 promoter 4G/5G polymorphism was not associated with histological grade or overall survival. CONCLUSIONS PAI-1 promoter 4G/5G polymorphism is associated with a relatively increased risk of breast cancer development and lymph node metastasis.

Abstract
BACKGROUND The levels of urokinase plasminogen activator (uPA) system in tumor tissues are implicated as prognostic biomarkers in a wide range of malignancies. However, their possible impact on the risk and prognosis of oral cancer and the susceptibility of environmental carcinogens to oral cancer remains poorly investigated. METHODS The genetic polymorphisms of uPA, uPA receptor (uPAR), and plasminogen activator inhibitor (PAI)-1 were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 253 patients with oral cancer and 344 healthy controls. RESULTS There was no significant effect of uPA system genes on the susceptibility of oral cancer; however, the impact of uPA system gene polymorphisms on the susceptibility of betel nut and tobacco consumptions to oral cancer was revealed, except for that of uPAR gene polymorphism on tobacco consumption. Patients with oral cancer with at least one 5G allele of PAI-1 gene have a low risk for the development of clinical stage III or IV (p ≤ 0.05) and lymph node metastasis (p ≤ 0.05) compared with those with 4G/4G homozygotes. CONCLUSIONS Our results suggest that the combination of uPA system gene polymorphisms and environmental carcinogens was related to the risk of oral cancer, and the genetic polymorphism of PAI-1 was associated with a low risk to the clinicopathological development of oral cancer.

Abstract
BACKGROUND The urokinase plasminogen activator (uPA) system is a serine proteinase system involved in extracellular matrix (ECM) degradation. The levels of uPA system components in tumor tissues are implicated as prognostic biomarkers in a wide range of malignancies. Although the contributions of uPA system components to the formation of many types of cancer are well known, their possible association with the prediction of risk and prognosis of hepatocellular carcinoma (HCC) remains poorly investigated. METHODS A total of 102 HCC patients and 344 controls were recruited. Genetic polymorphisms of uPA system genes, including uPA, uPA receptor (uPAR), and plasminogen activator inhibitor (PAI)-1, were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) genotyping analysis. RESULTS When individuals were classified into male and female subgroups to estimate adjusted odds ratios (AORs) with their 95% confidence intervals (CIs) of each uPA system gene, the HCC risks of males and females with PAI-1 5G/5G genotype were 6.06-fold (95% CI = 1.39-26.36) and 0.04-fold (95% CI = 0.003-0.69), respectively, as compared with those with PAI-1 4G/4G genotype. High risk for hepatitis B surface antigen (HBsAg)-positive clinical status and significantly higher serum aspartate aminotransferase (AST) concentration were exhibited in HCC patients with PAI-1 4G/5G and 5G/5G genotypes as compared with 4G/4G homozygotes. CONCLUSIONS The results suggest that PAI-1 genotypes could be an important factor contributing to increased susceptibility and pathological development of HCC in Taiwanese population.

Abstract
Uterine fibroids are the most common benign tumors of the female genital tract. Steroid hormones, especially estradiol and progesterone, play an important role in the pathobiology of this frequent disease. Recent studies suggested that both expression levels and polymorphisms of estrogen receptor (ER) alpha and beta might affect development of uterine fibroids. In this study, we tested whether single nucleotide polymorphisms (SNPs) in the promoter of estrogen receptor beta gene (ESR2) are associated with susceptibility to uterine fibroids. For this purpose, we compared the frequency of three SNPs in the promoter region of ESR2 gene (rs2987983, rs3020450 and rs3020449) in 101 women with uterine fibroids and 102 healthy women serving as controls by means of allele-specific tetra-primer polymerase chain reaction (PCR). Regarding allele frequency, allele positivity, genotype and haplotype frequencies of these SNPs we did not observe any significant difference between healthy women and women with uterine fibroids. In conclusion, our data clearly suggest that the tested SNPs in the promotor region of human ESR2 gene are not associated with the development of uterine fibroids.

Abstract
Genetic variations like single nucleotide polymorphisms (SNPs) in genes involved in estrogen biosynthesis, metabolism and signal transduction have been suggested to affect breast cancer susceptibility. In this study we tested the hypothesis that polymorphisms in the promoter of ESR2 gene may be associated with increased risk for breast cancer. We analyzed three SNPs in the promoter region of human ESR2 gene by means of allele-specific tetra-primer PCR. A total of 318 sporadic breast cancer cases and 318 age-matched controls were included in the study. With regard to homozygous genotypes, women with sporadic breast cancer more frequently carried the CC genotype of ESR2 promoter SNP rs2987983 (OR 1.99, p=0.005). Calculation of allele positivity demonstrated that presence of T allele of this SNP was more frequent in healthy women. Our data suggest that a SNP in the promoter region of ESR2 gene might be able to affect breast cancer risk. These results further support the emerging hypothesis that ERbeta is an important factor in breast cancer development.

Abstract
Extracellular matrix degradation, mediated by the urokinase plasminogen activation (uPA) system, is a critical step in tumor invasion and metastasis. High tumor levels of uPA and its inhibitor PAI-1 have been correlated with poor prognosis in breast cancer. We examined whether genetic variation in the genes of the uPA system affect breast cancer susceptibility and prognosis. We genotyped eight potentially functional single nucleotide polymorphisms (SNPs) in six genes of the uPA system in 959 Swedish breast cancer patients with detailed clinical data and up to 15 years of follow-up together with 952 matched controls. We used the unconditional logistic regression models to evaluate the associations between genotypes and breast cancer risk and tumor characteristics. The Kaplan-Meier method was used to estimate the survival probabilities; the log-rank test was used to test differences between subgroups. None of the SNPs conferred an increased breast cancer risk, but correlation with some traditional prognostic factors was observed for several SNPs. Most importantly, we identified the -675 4G/5G SNP in the PAI-1 gene as a promising prognostic biomarker for breast cancer. Compared to the 4G/4G and 4G/5G genotypes 5G/5G homozygosity correlated significantly with worse survival (RR 2.04, 95% CI 1.45-2.86, P<0.001), especially in patients with more aggressive tumors. 5G/5G homozygotes were also the group with worse survival among lymph node negative cases. Our finding suggests that genotyping PAI-1 -675 4G/5G may help in clinical prognosis of breast cancer.

Abstract
Aggressive fibromatosis is a mesenchymal neoplasm associated with mutations resulting in beta-catenin mediated transcriptional activation. Plasminogen activator inhibitor-1 (PAI-1) is expressed at a high level in aggressive fibromatosis, and using transgenic mice, we found that PAI-1 plays an important role in aggressive fibromatosis tumor formation. Familial adenomatous polyposis is associated with Adenomatous Polyposis Coli gene mutations resulting in beta-catenin mediated transcriptional activation, yet only some patients develop aggressive fibromatosis. Since PAI-1 expression is influenced by a promoter 4G/5G polymorphism, we investigated the incidence of this polymorphism in familial adenomatous polyposis patients who did and who did not develop aggressive fibromatosis, as well as sporadic aggressive fibromatosis patients. There was a trend towards association of the 4G allele (associated with high PAI-1 expression) with the development of aggressive fibromatosis in familial adenomatous polyposis patients (50% vs. 19%, P = 0.1). In familial adenomatous polyposis patients who did not develop aggressive fibromatosis, there was a significantly lower proportion of patients with a 4G allele compared to the healthy control (19% vs. 51%, P = 0.0286). The lower incidence of 4G polymorphism in the PAI-1 promoter may be preventive against the development of aggressive fibromatosis. This data provides additional evidence supporting an important role for PAI-1 in the pathogenesis of aggressive fibromatosis.

Abstract
AIMS PAI-1 (plasminogen activator inhibitors-1) regulates plasminogen activation, and is related to tumour development. This study aims to test whether the promoter polymorphism in the PAI-1 gene is related to the aggressiveness of disease in prostate cancer. MATERIALS AND METHODS In the present study, Taqman SNP genotyping assay was used to detect PAI-1 4G/5G polymorphism in DNA from paraffin-embedded tissues of 98 Caucasian patients with prostate cancer. RESULTS The distribution of the genotypes is in Hardy-Weinberg equilibrium. The genotype had no statistically significant relationship with other prognostic factors. Similar risks for recurrence were seen in individuals with the 4G/4G and 4G/5G genotypes compared to those with 5G/5G genotype (odds ratio [OR] 2.65, 95% CI: 0.41-16.94, P = 0.30; OR = 2.19, 95% CI: 0.38-12.49, P = 0.38). CONCLUSION We concluded that PAI-1 promoter polymorphism is not associated with the aggressiveness of disease in prostate cancer.

Abstract
BACKGROUND The plasminogen activator inhibitor type 1 (PAI-1) 4G/5G polymorphism may have significance for PAI-1 expression. High levels of PAI-1 in breast cancer patients are associated with a poor prognosis. In this study, we analyzed the influence of the PAI-1 4G/5G polymorphism on tissue PAI-1 levels and its association with tumor severity in women with breast cancer. MATERIAL AND METHODS We studied 104 women with breast carcinoma (patient group) and 104 healthy age-matched women (control group). In patients and controls, the PAI-1 4G/5G polymorphism was determined by PCR amplification using allele-specific primers. In patients, PAI-1 levels were quantified in breast cancer tissue by using an ELISA. RESULTS The frequency of the PAI-1 4G allele tended to be higher in patients than in controls (p=0.062). The presence of the 4G allele (4G/5G plus 4G/4G genotypes) was significantly higher among patients with histological grade 3 tumors than among those with grade 1 tumors (p=0.026). Furthermore, patients with the 4G/4G genotype had significantly higher tissue PAI-1 levels than those with the 5G/5G genotype. Moreover, tissue PAI-1 antigen levels were significantly and positively correlated with tumor severity (p=0.003) and tumor size (p=0.009). However, no significant differences in PAI-1 level were observed in relation to menopause, hormone receptor or nodal status. CONCLUSION Tissue PAI-1 antigen levels and tumor severity seem to be associated with the PAI-1 4G/5G polymorphism. Further studies with a larger number of patients are needed to clarify the influence of this polymorphism in breast cancer.

Abstract
PURPOSE Urokinase-type plasminogen activator (uPA), plasminogen activator inhibitor (PAI-1), and uPA receptor (uPAR) are prognostic factors in various cancer types, especially breast cancer. Less is known about the usefulness of these markers in breast cancer diagnosis. We sought to determine (1) whether uPA, PAI-1, and uPAR were detectable in breast nipple aspirate fluid (NAF), a physiologic fluid produced by the breast and collected noninvasively, and (2) the association of these markers in NAF with the presence of breast cancer. PATIENTS AND METHODS One hundred twenty NAF specimens were collected from women with and women without breast cancer. uPA, PAI-1, and uPAR expression in NAF was measured by enzyme-linked immunosorbent assay. RESULTS Median NAF PAI-1, but not uPA or uPAR, expression was higher in subjects with breast cancer than in those without breast cancer, regardless of whether expression was controlled for total NAF protein level. Median expression of PAI-1 per milligram of total NAF protein was higher in both premenopausal and postmenopausal women who had breast cancer than in women who did not. A multiple logistic regression model that included age, race, menopausal status, uPA, PAI-1, and uPAR level to differentiate patients with regard to cancer risk revealed that uPA, PAI-1, and age were each associated with risk (P < or = 0.019). Women whose NAF contained elevated uPA and PAI-1 levels were more likely to have cancer than women in whom both markers were not elevated. DISCUSSION Our data suggest that PAI-1, alone or in combination with uPA, may be useful as a noninvasive biologic marker to aid in the detection of breast cancer.
