Abstract
Breast cancer (BC) is a multistep disease that is thought to result from an interaction between genetic background and environmental factors. In Iran, one of the strongest risk factors for developing BC is a positive family history of the disease. Recently, various polymorphisms of E-cadherin (CDH1) and TERT have been found to be associated with increased BC risk worldwide. This study aimed to analyze the association of CDH1 and TERT single-nucleotide polymorphisms with susceptibility to familial BC (FBC) risk in the Iranian patients. One hundred five patients with FBC and 110 non-FBC (NFBC) were genotyped to elucidate the potential association between CDH1 rs5030625 polymorphism and TERT rs2736098 polymorphism by polymerase chain reaction-restriction fragment length polymorphism. Then, results were evaluated by electrophoresis and Epi Info(™) 2012 software. A significant association was found between CDH1 rs5030625 GAGA genotype and FBC risk. Compared with the control group, the FBC patients had a lower frequency of GG genotype (69% vs. 85%) and a higher frequency of GAGA (5% vs. 2%, P < 0.02). Furthermore, the patients with FBC had a lower frequency of TERT rs2736098 GG genotype (38% vs. 49%, P = 0.001) and a higher frequency of rs2736098 AA genotype (12% vs. 5%, P = 0.001) compared with the NFBC. In contrast, the TERT rs2736098 GG genotype potentially increased the recurring risk of FBC (odds ratio = 3.17, P < 0.01). Allele genotypic frequencies in the FBC patients differed from those of the controls. Interestingly, tumors in FBC patients with rs2736098 GG genotype and rs5030625 GAGA exhibited higher mitotic activity, higher grade, lower estrogen receptor, and progesterone receptor than the other genotypes. In conclusion, CDH1 rs5030625 GAGA genotype and TERT rs2736098 GG genotype in combination with clinical parameters may be prognostic factors rather than susceptibility factors during the progression of FBC.

Abstract
Epithelial-mesenchymal transition (EMT) was recently discovered related to the efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in NSCLC patients and cell lines. In this study, we aimed to explore the association among the E-cadherin gene (CDH1) genetic variants, TK-domain mutations of EGFR, and clinicopathologic characteristics in patients with lung adenocarcinoma. A total of 280 patients with lung adenocarcinoma were recruited between years 2012 and 2015. All subjects underwent the analysis of CDH1 genetic variants (rs16260 and rs9929218) by real-time polymerase chain reaction (PCR) genotyping. The results showed that CA and CA + AA genotypes of CDH1 single nucleotide polymorphism (SNP) rs16260 were significantly reverse associated with EGFR mutation type (Adjusted odds ratio (AOR) = 0.43, 95% CI = 0.20-0.92 and AOR = 0.46, 95% CI = 0.22-0.96, respectively) in female lung adenocarcinoma patients. Moreover, the significantly reverse associations between CA and CA + AA genotypes of CDH1 rs16260 and EGFR hotspot mutations, namely L858R mutation and exon 19 in-frame deletion, were also demonstrated among female patients. Besides, CA + AA genotype of CDH1 rs16260 was noted significantly reverse associated with the tumor sizes (OR = 0.31, 95% CI = 0.12-0.80; p = 0.012). In conclusion, our results suggested that CDH1 variants are significantly reverse associated with mutation of EGFR tyrosine kinase, especially among the female patients with lung adenocarcinoma. The CDH1 variants might contribute to pathological development in lung adenocarcinoma.

Abstract
AIM This case/control study aimed to assess the impact of two single nucleotide polymorphisms (SNPs) in the promoter region of CDH1 gene (-160C>A and -347G>GA) on urinary stone formation in a sample of Iraqi children. METHODS Forty-seven children with urolithiasis and 50 age- and gender-matched healthy controls were included in the study. DNA was isolated from peripheral blood and direct sequencing was used for genotyping. RESULTS The homozygous genotype of the SNP CHD1 -160C>A was more frequent in control than cases (18% vs. 6.38%) with significant difference (OR = 0.229, 95%CI = 0.056-0.943, P = 0.041). Furthermore, cases showed significantly less frequency of the mutant allele (allele A) of this SNP (OR = 0.403, 95%C = 0.210-0.776, P = 0.007). CONCLUSION These results strongly indicate a protective role of allele A of the SNP CHD1 -160C>A against urinary calculi formation in children.

Abstract
BACKGROUND E-cadherin is a major component of adherens junctions that regulates cell shape and maintains tissue integrity. A complete loss or any decrease in cell surface expression of E-cadherin will interfere with the cell-to-cell junctions' strength and leads to cell detachment and escape from the primary tumor site. In this prospective study, three functional single nucleotide polymorphisms (-347G/GA, rs5030625; -160C/A, rs16260; +54C/T, rs1801026), were found to modulate E-cadherin expression. METHODS 577 DNA samples from breast cancer (BC) cases were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS We detected no significant correlations between each polymorphism and the clinical parameters of the patients whereas the GACC haplotype was significantly associated with low SBR grading. Overall survival analysis showed that both -347G/G and +54C/C wild (wt) genotypes had a significantly worse effect compared to the other genotypes (non-wt). Moreover, carrying simultaneously both the -347 and +54 wt genotypes confers a significantly higher risk of death. However, with metastatic recurrence, the death-rate was null in patients carrying the non-wt genotypes, and attained 37% in those carrying the wt genotype. A multivariate analysis showed that these two polymorphisms are independent prognostic factors for overall survival in BC patients. CONCLUSIONS Our results support the fact that E-cadherin genetic variants control disease severity and progression and could be a marker of disease outcome. These findings could be useful in selecting patients that should be monitored differently.

Abstract
ObjectiveThe E-cadherin protein plays major roles in tumor progression, invasion, and metastasis. Polymorphisms located in the E-cadherin gene (CDH1) may contribute to increased risks of specific cancers. In this study, we evaluated the associations between genetic variants inCDH1and the clinical outcomes of patients with epithelial ovarian cancer (EOC).Materials and MethodsWe assessed the−160C/Aand−347G/GApolymorphisms in the promoter region, as well as the3′-UTR +54C/Tpolymorphism of E-cadherin, in 257 patients with EOC by ligase detection reaction–polymerase chain reaction.ResultsMultivariate analysis showed that patients with EOC with theCDH1 −347GA/GAgenotype had shorter progression-free survival and overall survival (hazard ratio [HR], 2.16; 95% confidence interval [CI], 1.06–4.40 and HR, 2.06; 95% CI, 1.01–4.19, respectively) compared to those carrying the G/G genotype. Likewise, the patients with theCDH1 −160A/Agenotype had a shorter progression-free survival than those with the C/C genotype (HR, 4.12; 95% CI, 1.43–111.88). No significant association was detected between theCDH1 3′-UTR +54C/Tpolymorphism and survival of the patients with EOC.ConclusionsTheCDH1 −347GA/GAand−160A/Agenotypes may be prognostic markers that can help to identify patients at increased risk of invasive/metastatic cancer in northern China.

Abstract
Purpose To study whether −160 C > A (rs16260) and −347 G > GA (rs5030625) single nucleotide polymorphisms of the regulatory region (rSNPs) of CDH1 gene modulate the risk of nephrolithiasis. Methods Genomic DNA of 101 patients with calcium oxalate nephrolithiasis and 114 healthy controls were screened for both polymorphisms, using polymerase chain reaction-restriction fragments length polymorphism method (PCR-RLFP). Haplotype frequencies were also analyzed. To determine the association of rSNPs of CDH1 gene with the clinicopathological features of nephrolithiasis, nearly all possible etiological factors were documented. These factors were family history, gender, age, body mass index, liquid consumption, eating habits, tea–coffee and meat (oxalate rich) consumption, adequate physical activity, and all serum and urine levels—the serum levels of Na, K, Cl, phosphate, Ca, Mg, uric acid, albumin, blood urea nitrogen (BUN), creatinine and serum parathyroid hormone (PTH) as well as 24 h urine excretions of creatinine, Na, K, Cl, phosphate, Ca, Mg, citrate, oxalate, uric acid, albumin and BUN. Results Significant differences were found between rs16260 and the risk of nephrolithiasis. Patients having CA genotype of rs16260 CDH1 polymorphism were associated with an almost trifold increased risk for developing kidney stone than those with the AA genotype (95 % CI 1.08–7.28, OR 2.8, P = 0.033). We also found that non-A allele carriers (CC) had significantly higher nephrolithiasis risk associated with the clinicopathological characteristics including serum calcium (P = 0.027) and 24 h urinary magnesium level (P = 0.042). Moreover, we did find a directly proportional relationship between the CA genotype and serum calcium levels (P = 0.041). There was no significant difference between patients and controls in terms of the distribution of rs5030625 genotypes and alleles (P > 0.05). Likewise, no associations between the rs16260 and rs5030625 haplotypes and susceptibility to kidney stone were observed (P > 0.05). Conclusion Regulatory variants of rs16260 of the CDH1 gene may confer susceptibility to nephrolithiasis. This may have important implications for understanding the pathophysiological mechanisms of the disease and suggesting novel targets for drug treatment.

Abstract
Hepatocellular carcinoma (HCC) is etiologically linked with hepatitis B virus (HBV) and is the leading cause of death amongst 80% of HBV patients. Among HBV affected patients, genetic factors are also involved in modifying the risk factors of HCC. However, the genetic factors that regulate progression to HCC still remain to be determined. In this review, we discuss several single nucleotide polymorphisms (SNPs) which were reportedly associated with increased or reduced risk of HCC occurrence in patients with chronic HBV infection such as cyclooxygenase (COX)-2 expression specifically at COX-2 -1195G/A in Chinese, Turkish and Egyptian populations, tumor necrosis factor α and the three most commonly studied SNPs: PAT-/+, Lys939Gln (A33512C, rs2228001) and Ala499Val (C21151T, rs2228000). In genome-wide association studies, strong associations have also been found at loci 1p36.22, 11q22.3, 6p21 (rs1419881, rs3997872, rs7453920 and rs7768538), 8p12 (rs2275959 and rs37821974) and 22q11.21. The genes implicated in these studies include HLA-DQB2, HLA-DQA1, TCF19, HLA-C, UBE2L3, LTL, FDX1, MICA, UBE4B and PG. The SNPs found to be associated with the above-mentioned genes still require validation in association studies in order to be considered good prognostic candidates for HCC. Screening of these polymorphisms is very beneficial in clinical experiments to stratify the higher or lower risk for HCC and may help in designing effective and efficient HCC surveillance programs for chronic HBV-infected patients if further genetic vulnerabilities are detected.

Abstract
Background Colorectal Cancer (CRC) is one of the most frequently diagnosed neoplasms and also one of the main death causes. Cell adhesion molecules are taking part in specific junctions, contributing to tissue integrality. Lower expression of the cadherins may be correlated with poorer differentiation of the CRC, and its more aggressive phenotype. The aim of the study is to designate the cadherin genes potentially useful for the diagnostics, prognostics, and the treatment of CRC. Material/Method Specimens were collected from 28 persons (14 female and 14 male), who were operated for CRC. The molecular analysis was performed using oligonucleotide microarrays, mRNA used was collected from adenocarcinoma, and macroscopically healthy tissue. The results were validated using qRT-PCR technique. Results Agglomerative hierarchical clustering of normalized mRNA levels has shown 4 groups with statistically different gene expression. The control group was divided into 2 groups, the one was appropriate control (C1), the second (C2) had the genetic properties of the CRC, without pathological changes histologically and macroscopically. The other 2 groups were: LSC (Low stage cancer) and HSC (High stage cancer). Consolidated results of the fluorescency of all of the differential genes, designated two coding E-cadherin (CDH1) with the lower expression, and P-cadherin (CDH3) with higher expression in CRC tissue. Conclusions The levels of genes expression are different for several groups of cadherins, and are related with the stage of CRC, therefore could be potentially the useful marker of the stage of the disease, also applicable in treatment and diagnostics of CRC.

Abstract
Single nucleotide polymorphisms (SNPs) occurring in noncoding sequences have largely been ignored in genome-wide association studies (GWAS). Yet, amounting evidence suggests that many noncoding SNPs especially those that are in the vicinity of protein coding genes play important roles in shaping chromatin structure and regulate gene expression and, as such, are implicated in a wide variety of diseases. One of such regulatory SNPs (rSNPs) is the E-cadherin (CDH1) promoter -160C/A SNP (rs16260) which is known to affect E-cadherin promoter transcription by displacing transcription factor binding and has been extensively scrutinized for its association with several diseases especially malignancies. Findings from studying this SNP highlight important clinical relevance of rSNPs and justify their inclusion in future GWAS to identify novel disease causing SNPs.

Abstract
BACKGROUND Environmental tobacco smoke (ETS) is a risk factor for asthma. Importantly, cigarette smoke can decrease the adherence of epithelial cells and increase detachment. The adhesion molecule E-cadherin (CDH1) has an essential role in the formation of epithelial junction. Turnover of the extracellular matrix, which is characterized by airway remodeling, depends on the imbalance between matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinase (TIMPs). OBJECTIVE To evaluate the effects of ETS exposure and CDH1, MMP-3, and TIMP-1 genetic polymorphisms on childhood asthma. METHODS The CDH1 C-160A, MMP-3 -1171, and TIMP-1 T372C genotypes were identified by polymerase chain reaction in 299 asthmatic children and 383 healthy controls. RESULTS More ETS exposure (>5 vs 0 cigarettes/day; odds ratio [OR], 1.45; 95% confidence interval [CI], 1.05-2.01) and the presence of CDH1 AA/CA genotypes (OR, 1.53; 95% CI, 1.08-2.17) were associated with childhood asthma. Compared with children with less ETS exposure (0-5 cigarettes/day) and the CDH1 CC genotype, those with less ETS exposure and the CDH1 AA/CA genotypes and those with more ETS exposure and the CDH1 CC genotype had a moderate risk of asthma. The greatest risk for asthma was in children with more ETS exposure and the CDH1 AA/CA genotypes (OR, 3.03; 95% CI, 1.81-5.06), and this interaction between CDH1 polymorphism and ETS exposure was significant. In addition, asthma cases with more ETS exposure or the CDH1 AA/CA genotypes had obviously increased eosinophil counts. CONCLUSION Susceptible CDH1 genotypes might modulate the development of asthma, especially for children exposed to ETS.

Enhanced tumorigenesis and lymphatic metastasis of CD133+ hepatocarcinoma ascites syngeneic cell lines mediated by JNK signaling pathway in vitro and in vivo. Biomed Pharmacother 2013; 67:337-45. [PMID: 23582787 DOI: 10.1016/j.biopha.2013.02.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2013] [Accepted: 02/03/2013] [Indexed: 02/08/2023] Open
Abstract
Cancer stem cells (CSCs), stem-like cells, or tumor-initiating cells (TICs) may initiate tumorigenesis and metastasis, but neither the basic cell biology of CSCs nor the mechanisms of CSC-mediated tumor growth and lymphoid node metastasis are understood. Evidence suggests that CSC phenotype is maintained, at least in part, by altered JNK signaling. In this study, factors influencing the growth and metastatic potential of CSCs were examined by comparing CD133 surface antigen expression, proliferation, clonogenicity, invasive capacity, tumorigenicity, and expression of JNK-associated signaling molecules between the highly metastatic mouse hepatocarcinoma ascites syngeneic cell line Hca-F and the low metastasis potential line Hca-P. The Hca-F line exhibited higher clonogenic, proliferative, and invasive capacities than Hca-P cells, and a greater proportion of Hca-F cells were CD133 positive. In both cell lines, the CD133+ subpopulation showed significantly enhanced tumorigenicity and metastatic potential. An in vivo tumorigenicity assay in nude mice indicated that Hca-F cells possessed significantly higher tumorigenicity than Hca-P cells as indicated by larger tumors after inoculation. Expression levels of E-cadherin (CDH1), annexin VII, and JNK1 proteins were inversely correlated with CD133 expression in both Hca-F and Hca-P cells. These results demonstrate that CD133+ subpopulations of both Hca-F and Hca-P lines show CSC-like properties. However, Hca-F cells showed greater tumorigenicity and invasiveness, consistent with greater lymphatic metastasis capacity. We propose that tumorigenesis and lymphatic metastasis are regulated by JNK/P53/annexin VII and JNK/ATF-2/CDH1/annexin VII signal transduction pathways.

Effects of NFKB1 and NFKBIA gene polymorphisms on hepatocellular carcinoma susceptibility and clinicopathological features. PLoS One 2013; 8:e56130. [PMID: 23457512 PMCID: PMC3573054 DOI: 10.1371/journal.pone.0056130] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2012] [Accepted: 01/05/2013] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Constitutive activation of nuclear factor (NF)-κB is frequently observed in hepatocellular carcinoma (HCC). The current study examined associations of polymorphisms within promoter regions of NFKB1 encoding NF-κB1 and NFKBIA encoding IκBα with the susceptibility of developing HCC and clinicopathological characteristics of the tumors. METHODOLOGY AND PRINCIPAL FINDINGS Genetic polymorphisms of NFKB1 and NFKBIA were analyzed by a real-time polymerase chain reaction (PCR) in 135 HCC patients and 520 healthy controls. The genotypic frequency of the NFKB1 -94 Ins polymorphism in HCC patients was significantly higher than that of the controls (adjusted odds ratio (AOR) = 2.23; 95% confidence interval (CI) 1.32∼3.77). No statistical significance was observed for the distribution frequency of the NFKBIA --519 C/T, -826 C/T, or -881 A/G genotype and haplotype polymorphisms between HCC patients and controls. Furthermore, female HCC patients carrying the NFKB1 -94 Ins polymorphism were associated with lower clinical stages and smaller tumor sizes. CONCLUSIONS Our results indicate that the NFKB1 -94 Ins promoter polymorphism increased the risk of HCC, and may be applied as a predictive factor for the clinical stage and tumor size in female HCC patients.

Contribution of the -160C/A polymorphism in the E-cadherin promoter to cancer risk: a meta-analysis of 47 case-control studies. PLoS One 2012; 7:e40219. [PMID: 22792244 PMCID: PMC3390351 DOI: 10.1371/journal.pone.0040219] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2012] [Accepted: 06/02/2012] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND The -160C/A polymorphism (rs16260) of E-cadherin, a tumor repressor gene, has been shown to be a tumor susceptibility allele for various types of cancers. Because the significance of this polymorphism to cancer risk has been recognized, there are increasing studies investigating -160C/A in different types of cancers and ethnic populations. However, there is still uncertainty about the level of risk for a variety of cancers. METHODS To resolve the controversial question raised by these studies as of March 2012 and provide more statistical power for detecting the significance of -160C/A, we performed a meta-analysis of 47 case-control studies in 16 types of cancers (18,194 cases and 20,207 controls). A meta-regression model and subgroup analysis were employed to identify the source of heterogeneity. Publication bias was evaluated, and sensitivity analysis and cumulative evidence assessment were also performed. RESULTS Using fixed- and random-effects models, the -160AA homozygote was more susceptible to urothelial cancer compared with the -160CA heterozygote. Additionally, the -160A allele is an ethnicity-dependent risk factor for prostate and colorectal cancers. Carriers of the -160A allele in Asians and Europeans were more susceptible to prostate cancer, whereas their North American counterparts seemed tolerant. The -160AA homozygote plays a protective role for Europeans who develop colorectal cancer. The stability of these observations was confirmed by a one-way sensitivity analysis. However, the cumulative evidence for all cancer types was considered 'weak' using the Venice guidelines. CONCLUSIONS A meta-analysis indicated that the -160A allele of E-cadherin provides a higher risk for the development of prostate and urothelial cancers and a protective role for colorectal cancer in an ethnicity-dependent manner.

Abstract
BACKGROUND The reversion-inducing-cysteine-rich protein with Kazal motifs (RECK) down-regulation has been confirmed in numerous human cancers and is clinically associated with metastasis. This study investigates the potential associations of RECK single-nucleotide polymorphisms (SNPs) with hepatocellular carcinoma (HCC) susceptibility and its clinicopathologic characteristics. METHODOLOGY/PRINCIPAL FINDINGS A total of 135 HCC cancer patients and 501 cancer-free controls were analyzed for four RECK SNPs (rs10814325, rs16932912, rs11788747, and rs10972727) using real-time PCR and PCR-RFLP genotyping analysis. After adjusting for other co-variants, the individuals carrying RECK promoter rs10814325 inheriting at least one C allele had a 1.85-fold [95% confidence interval (CI), 1.03-3.36] risk of developing HCC compared to TT wild type carriers. The HCC patients, who carried rs11788747 with at least one G allele, had a higher distant metastasis risk than wild type probands. CONCLUSIONS RECK gene polymorphisms might be a risk factor increasing HCC susceptibility and distant metastasis in Taiwan.

Abstract
OBJECTIVE Published data on the relationship between E-cadherin (CDH1) gene promoter polymorphisms and colorectal cancer (CRC) risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was carried out. METHODS In this meta-analysis, we evaluated reported studies of associations between polymorphisms of CDH1 gene promoter -160 C > A and -347 G > GA site, and CRC risk using fixed-effects model and random-effects model. RESULTS We found decreased CRC risk among subjects carrying CDH1 -160AA (odds ratio [OR] = 0.86, 95 percent confidence interval [95% CI]: 0.75-0.98) and CA + AA (OR = 0.92, 95% CI: 0.87-0.98), using 4,652/4,428 cases/controls and 7,866/7,689 cases/controls from ten studies, respectively. We found a protective effect of the CDH1 -160CA + AA polymorphisms for CRC in distal site tumor population and population-based control in stratified analysis. We found a protective effect of the CDH1 -160AA and CA + AA polymorphisms for CRC in European and American population (OR = 0.87, 95% CI: 0.76-0.99 and OR = 0.91, 95% CI: 0.85-0.98, respectively). We observed that the CDH1 -347 G/GA + GA/GA carrier had an increased risk of CRC, the summary OR was 1.33 (95% CI: 1.08-1.62). CONCLUSIONS Data indicated that certain CDH1 gene promoter -160 C > A and -347 G > GA variants might affect the susceptibility of CRC. Recommendations for further studies include pooling of individual data to facilitate evaluation of multigenic effects and detailed analysis of effect modification by environmental and lifestyle factors.

Abstract
BACKGROUND AND OBJECTIVES Hepatocellular carcinoma (HCC) is one of the most frequent malignant neoplasms worldwide, and the second leading cause of death from cancer in Taiwan. Interleukin-8 (IL-8) is an angiogenic chemokine with important roles in the development and progression of many human malignancies including HCC. This study investigates the effects of single-nucleotide polymorphisms (SNPs) in the IL-8 gene on the susceptibility and clinicopathological characteristics of HCC. METHODS One hundred thirty-one HCC patients and 340 control subjects were analyzed for four IL-8 SNPs (-251 T/A, +781 C/T, +1633 C/T, and +2767 A/T) using PCR-RFLP genotyping analysis. RESULTS After adjusting for other confounders, results show that individuals with the IL-8 +781 T/T polymorphic genotype had a significantly lower risk of developing HCC than those with the wild-type (C/C) genotype (AOR = 0.346; 95% CI: 0.132-0.909). Multiple regression analysis showed that the presence of T/A or A/A at IL-8 -251 may indicate higher potential risk of hepatitis B infection (AOR = 2.847; 95% CI: 1.083-8.656). Additionally, these four IL-8 SNPs did not associate with liver-related clinicopathological markers in serum. CONCLUSIONS Genetic polymorphism at IL-8 +781 is an important factor in determining susceptibility to HCC in the Taiwanese population.
