THE CLINICAL RESPIRATORY JOURNAL 2021; 15:637-647. [PMID: 33484055 DOI: 10.1111/crj.13335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 01/13/2021] [Accepted: 01/19/2021] [Indexed: 12/09/2022]
Abstract
OBJECTIVE This study was conducted to evaluate the relationship between the p73 G4C14-to-A4T14 polymorphism (hereafter, G4C14-to-A4T14) and lung cancer risk. METHODS The studies on the relationship between G4C14-A4T14 and lung cancer risk published as of November 5, 2018, were comprehensively searched in PubMed, Embase, the Cochrane Library, the Chinese Wanfang database, China National Knowledge Infrastructure (CNKI), and China Biology Medicine (CBM). The last update was on May 24, 2019. Statistical analysis was performed using Stata 12.0. RESULTS The association between G4C14-A4T14 and lung cancer risk was analyzed in nine studies. The findings indicate no association between G4C14-to-A4T14 and lung cancer risk (allele model: OR = 0.90, 95% CI: 0.73-1.11, I2 = 86.0%, P = .330; dominant model: OR = 0.93, 95% CI: 0.74-1.17, I2 = 82.6%, P = .551; recessive model: OR = 0.75, 95% CI: 0.50-1.13, I2 = 75.2%, P = .165; homozygote model: OR = 0.74, 95% CI: 0.47-1.17, I2 = 79.6%, P = .199; heterozygote model: OR = 0.98, 95% CI: 0.80-1.21, I2 = 75.8%, P = .879). The heterogeneity between subgroups by cancer types and genotyping method was significantly reduced. After the deletion of suspected duplicates, no association was found between G4C14-to-A4T14 and lung cancer susceptibility. CONCLUSION Our meta-analysis confirms that G4C14-to-A4T14 is not significantly related to lung cancer risk.

Abstract
AIM Available data concerning the association between RAD51 135G/C (rs1801320) polymorphism and the risk of 3 common gynecological cancers still could not reach a consensus. Thus, we conducted a meta-analysis to explore the relationship. METHODS Several electronic databases and bibliographies of relevant articles were screened to identify the studies up to July 2017. Then a meta-analysis was performed to evaluate the connection between 3 common gynecological tumors' susceptibility and RAD51 135G/C polymorphism in different inheritance models. Simultaneously, we did subgroup analysis and sensitivity analysis if necessary. RESULTS A total of 11 articles including 14 studies involving 4097 cases and 5890 controls were included in this meta-analysis. Overall, RAD51 135G/C polymorphism increased the risk of 3 common gynecological tumors. The subgroup analysis stratified by cancer types- endometrial carcinoma (EC) and ovarian cancer (OC)-showed that RAD51 135G/C polymorphism increased the risk of EC: allele model (C vs G: odds ratio [OR] = 4.32, 95% confidence interval [CI] = 2.63-7.10, P < .00001), dominant model (CC + GC vs GG: OR = 2.28, 95% CI = 1.44-3.60, P = .004), recessive model (CC vs GC + GG: OR = 10.27, 95% CI = 14.71-22.38, P < .00001), and homozygous model (CC vs GG: OR = 7.26, 95% CI = 3.59-14.68, P < .00001), but there was no significant association between RAD51 135G/C polymorphism and OC. In the subgroup analysis stratified by source of controls, a significantly increased risk was observed in hospital-based studies. Nevertheless, the data showed RAD51 135G/C polymorphism had no link in population-based studies. CONCLUSIONS This meta-analysis suggested that RAD51 135G/C polymorphism was a risk factor for the three common gynecological tumors, especially for EC among hospital-based populations.

Abstract
Background: Breast cancer is the commonest cancer in Egyptian females. Nrf2 is involved in oxidative stress while P73 functions in response to DNA damage. This study aimed to assess the role of Nrf2 promoter and P73 G4C14 to A4T14 SNPs in breast cancer in Egypt. Patients: Eighty-five female patients with breast tumours (41 malignant, 44 benign) were included. Nrf2 (rs6721961) and p73 (G4A) SNPs were determined by PCR- CTPP assay. Results: Genotype frequencies of the Nrf2 promoter SNP were 34.2% and 37.9% for AA in benign and malignant groups respectively, and 43.9% and 40.5% for CC and, 21.9 % and 21.6% for CA. Genotype frequencies for the P73 G4A SNP were 52.9% and 44.7% for GA in benign and malignant groups respectively, and 47.1% and 55.3% for GG. Discussion: Nrf2 genotypes in pre - and post-menopausal patients, showed significantly different distributions in the 2 patient groups, the AA genotype being significantly more common in pre-menopausal patients. The P73 G4A SNP showed no relation to age of disease onset. Conclusion: The Nrf2 (rs6721961) AA genotype might be related to early breast cancer onset. In contrast the P73 G4A polymorphism showed no relation to either disease risk or age at presentation.

Abstract
This study is to evaluate the association between p73 G4C14-A4T14 polymorphism and squamous cell carcinoma (SCC) risk in diverse populations. We searched the PubMed, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine databases for all articles on the association between p73 G4C14-A4T14 polymorphism and SCC risk through March 2014. We performed a comprehensive meta-analysis of six case-control studies that included 1,758 SCC cases and 2,970 case-free controls. All analyses were performed using STATA 11.0, using two-sided P values. Overall, this meta-analysis showed that the p73 G4C14-A4T14 polymorphism was associated with a significantly increased risk of SCC in three genetic models. However, after excluding one study deviating from Hardy-Weinberg equilibrium, the results then demonstrated that the p73 G4C14-A4T14 polymorphism was only associated with elevated risk of cervical squamous cell carcinoma (for AT/GC vs GC/GC: OR 1.51, 95 % CI 1.14-2.00, P heterogeneity = 0.996; for AT/AT+AT/GC vs GC/GC: OR 1.42, 95 % CI 1.08-1.87, P heterogeneity = 0.994) in subgroup analysis by tumor sites. No publication bias was found in the present study. This meta-analysis suggests that the p73 G4C14-A4T14 polymorphism is associated with an increased risk of cervical squamous cell carcinoma. Further large and well-designed studies are needed to confirm this association.

Role of p73 Dinucleotide Polymorphism in Prostate Cancer and p73 Protein Isoform Balance. Prostate Cancer 2014; 2014:129582. [PMID: 25097786 PMCID: PMC4109114 DOI: 10.1155/2014/129582] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2014] [Revised: 05/21/2014] [Accepted: 05/22/2014] [Indexed: 12/13/2022] Open
Abstract
Background. Molecular markers for prostate cancer (PCa) risks are currently lacking. Here we address the potential association of a dinucleotide polymorphism (DNP) in exon 2 of the p73 gene with PCa risk/progression and discern any disruption of p73 protein isoforms levels in cells harboring a p73 DNP allele. Methods. We investigated the association between p73 DNP genotype and PCa risk/aggressiveness and survival by fitting logistic regression models in 1,292 incident cases and 682 controls. Results. Although we detected no association between p73 DNP and PCa risk, a significant inverse relationship between p73 DNP and PCa aggressiveness (AT/AT + GC/AT versus GC/GC, OR = 0.55, 95%Cl = 0.31–0.99) was detected. Also, p73 DNP is marginally associated with overall death (dominant model, HR = 0.76, 95%Cl = 0.57–1.00, P = 0.053) as well as PCa specific death (HR = 0.69, 95%Cl = 0.45–1.06, P = 0.09). Western blot analyses for p73 protein isoforms indicate that cells heterozygous for the p73 DNP have lower levels of ∆Np73 relative to TAp73 (P < 0.001). Conclusions. Our findings are consistent with an association between p73 DNP and low risk for PCa aggressiveness by increasing the expressed TAp73/∆Np73 protein isoform ratio.

Abstract
Because of their important roles in mediating the stabilization and expression of p53, we hypothesized that high-risk genotypes of polymorphisms in p53-related genes, including p53, p73, p14(ARF), MDM2 and MDM4, may be associated with an increased risk of second primary malignancy (SPM) after index squamous cell carcinoma of the head and neck (SCCHN). We analyzed data from a cohort of 1283 patients with index SCCHN who were recruited between 1995 and 2007 at MD Anderson Cancer Center and followed for SPM development. Patients were genotyped for nine polymorphisms of p53-related genes. A log-rank test and Cox models were used to compare SPM-free survival and risk. Our results demonstrated that each p53-related polymorphism had a moderate effect on increased SPM risk, but when we combined risk genotypes of these nine polymorphisms together, we found that SPM-free survival was significantly shorter among risk groups with a greater number of combined risk genotypes. SPM risk increased with increasing number of risk genotypes (P < 0.0001 for trend). Compared with the low-risk group (0-3 combined risk genotypes), both the medium-risk (4-5 combined risk genotypes) and high-risk (6-9 combined risk genotypes) groups had significantly increased SPM risk [hazard ratio (HR): 1.6; 95% confidence interval (CI): 1.0-2.6 and HR: 3.0; 95% CI: 1.8-5.0, respectively]. Moreover, such significant associations were even higher in several subgroups. Our findings suggest that combined risk genotypes of p53-related genes may jointly modify SPM risk, especially in patients who are smokers and those with index non-oropharyngeal cancers. However, larger studies are needed to validate our findings.

Abstract
p73 gene shares structural and functional similarities to p53 and plays an important role in modulating cell cycle arrest and apoptosis. A common non-coding polymorphism of p73 G4C14-to-A4T14 (rs2273953 and rs1801173) at exon 2 may affect gene expression, thus, it may lead to functional significance. The correlation of this polymorphism with clinicopathologic variables of patients with breast cancer has not been investigated. In this study, single-nucleotide polymorphisms (SNPs) of p73 G4C14-to-A4T14 were genotyped by Sequenom MassArray-iPLEX GOLD System in 170 patients with breast cancer. Data were analyzed via t test, chi-square test, and logistic regression analysis. There was no significant correlation between p73 G4C14-to-A4T14 polymorphisms and the patient characteristics, such as clinical TNM stage, menopausal status, axillary lymph node metastasis, pathological type, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2). No significant relationship was observed between the p73 G4C14-to-A4T14 polymorphism and p73 protein expression in cancer tissues. The frequency of GC/GC genotype in patients with triple-negative breast cancer (TNBC) was 78.9 %, that of patients with others was 57.6 %, and the difference had statistical significance (χ ( 2 ) = 5.74, P = 0.02). p73 G4C14-to-A4T14 polymorphisms were negatively correlated with chemosensitivity for anthracycline-based chemotherapy in breast cancer (P > 0.05). p73 G4C14-to-A4T14 polymorphisms are positively correlated with TNBC, and p73 gene may play a critical role in a novel therapeutic strategy to TNBC. Additional larger studies are required to test these hypotheses.

Abstract
The aim of this study was to evaluate the association of p73 G4C14-A4T14 polymorphisms with susceptibility to breast cancer in Chongqing women of Han Nationality in China. In a case-control study, single-nucleotide polymorphisms of p73 G4C14-A4T14 at exon 2 were genotyped by Sequenom MassArray(®) iPLEX GOLD System in 170 patients with breast cancer and 178 healthy controls. Data were analyzed via t test, Chi-square test, and logistic regression analysis. The distribution of p73 genotypes and allelotypes had no significant difference between patients with breast cancer and healthy controls (χ(2) = 2.750, P = 0.253; χ(2) = 2.195, P = 0.138). More risk of developing triple negative breast cancer (TNBC) was found in the individuals who carried with GC/GC genotype than individuals carried with GC/AT and AT/AT genotypes (OR = 2.99; 95 % CI, 1.30-6.89; P = 0.010). p73 G4C14-A4T14 polymorphisms are closely associated with the increased risk for TNBC in Chongqing women of Han Nationality in China; GC/GC genotype is susceptible genotype for TNBC in Chongqing women of Han Nationality in China. The patients with breast cancer who carried with GC/GC genotype may have bad prognosis. Additional larger studies are required to confirm these findings.
