Effect of ERCC1 polymorphisms on the response to platinum-based chemotherapy: A systematic review and meta-analysis based on Asian population. PLoS One 2023; 18:e0284825. [PMID: 37141338 PMCID: PMC10159199 DOI: 10.1371/journal.pone.0284825] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Accepted: 04/06/2023] [Indexed: 05/06/2023] Open
Abstract
BACKGROUND Platinum-based chemotherapy is one of the most common treatments for many cancers; however, the effect of chemotherapy varies from individual to individual. Excision repair cross complementation group 1 (ERCC1) is widely recognized as a key gene regulating nucleotide excision repair (NER) and is closely associated with platinum response. Many studies have yielded conflicting results regarding whether ERCC1 polymorphisms can affect the response to platinum and overall survival (OS). Therefore, it is necessary to perform a meta-analysis of patients with specific races and cancer types. METHODS Eight databases (EMBASE, PubMed, Cochrane Library, Chinese National Knowledge Infrastructure, Scopus, VIP, China Biology Medicine disc and Wanfang databases) were searched. Results were expressed in terms of odds ratios (ORs), hazard ratios (HRs) and 95% CIs. RESULTS In this study, rs11615, rs2298881 and rs3212986 SNPs were studied. In the comparison between CT and TT on the response to platinum, esophageal cancer [I2 = 0%, OR = 6.18, 95% CI(1.89,20.23), P = 0.003] and ovarian cancer [I2 = 0%, OR = 4.94, 95% CI(2.21,11.04), P<0.001] showed that the rs11615 CT genotype predicted a better response. In the comparison between CC and TT, ovarian cancer [I2 = 48.0%, OR = 6.15, 95% CI (2.56,14.29), P<0.001] indicated that the CC genotype predicted a better response. In the meta-analysis of OS, the CC genotype was related to longer OS than TT in ovarian cancer [TT vs CC: I2 = 57.7%, HR = 1.71, 95% CI (1.18, 2.49), P<0.001]. CONCLUSION The ERCC1 rs11615 polymorphism was related to the response to platinum and OS, but the correlation is based on specific cancer types in the Asian population.

Evaluating Salmonella pullorum dissemination and shedding patterns and antibody production in infected chickens. BMC Vet Res 2022; 18:240. [PMID: 35751066 PMCID: PMC9229423 DOI: 10.1186/s12917-022-03335-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 06/07/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Pullorum disease caused by Salmonella pullorum is one of the most important infectious diseases in the poultry industry, responsible for causing substantial economic losses globally. On farms, the traditional method to detect S. pullorum infection mainly involves the collection of feces and sera to test for antigens and antibodies, respectively, but the regularity of Salmonella pullorum dissemination in internal organs and shedding patterns and antibody production in infected chickens remains unclear. Herein we aimed to investigate the dissemination of S. pullorum to different organs and bacterial shedding patterns in the faeces as well as serum antibody production post-infection in chickens of different ages. RESULT In this study, the liver and heart of 2-day-old chickens showed the highest copy numbers of S. pullorum at 6.4 × 106 and 1.9 × 106 copies of DNA target sequences/30 mg, respectively. In case of 10-day-old chickens, the percentage of S. pullorum fecal shedding (0%-40%) and antibody production (0%-56.6%) markedly fluctuated during the entire experiment; furthermore, in case of 42-week-old chickens, the percentage of birds showing S. pullorum shedding in the faeces showed a downward trend (from 63.33% to 6.6% in the oral inoculation group and from 43.3% to 10% in the intraperitoneal injection group), while that of birds showing serum antibody production remained at a high level (38.3% and 80% in the oral inoculation and intraperitoneal injection groups, respectively). We also performed cohabitation experiments, showed that 15% 10-day-old and 3.33% 42-week-old chickens were infected via the horizontal transmission in cohabitation with S. pullorum infected chickens, and revealed a high risk of horizontal transmission of S. pullorum. CONCLUSION This study systematically evaluated the dissemination of S. pullorum in internal organs and bacterial fecal shedding patterns, and antibody production in infected chickens. Collectively, our findings indicate how to effectively screen S. pullorum-negative chickens on livestock farms and should also help in the development of measures to control and eradicate S. pullorum.

XPF -673C>T variation is associated with the susceptibility to breast cancer. Cancer Epidemiol 2021; 74:102007. [PMID: 34416547 DOI: 10.1016/j.canep.2021.102007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 08/02/2021] [Accepted: 08/08/2021] [Indexed: 11/22/2022]
Abstract
PURPOSE XPF variations might decrease the DNA repair capacity and further contribute to cancer development. This study aimed to investigate the association of XPF polymorphisms with risk of developing breast cancer. METHODS TCGA, the Human Protein Atlas and Kaplan-Meier plotter were used to analyze the expression of XPF in breast cancer tissues and its effect on the survival of breast cancer patients. The expression of XPF in breast cancer tissues was detected by qRT-PCR. This case-control study included 467 breast cancer patients and 467 healthy controls. The genotype of genetic variation was detected by polymerase chain reaction restriction fragment length polymorphism. Odds ratios and 95 % confidence intervals were calculated. Correlations between XPF variation and clinicopathological parameters were assessed through Kendall's Tau-b test. The relationship between XPF gene function variation and XPF gene expression was analyzed by GTEx. RESULTS The expression of XPF in breast cancer tissues is higher than that in normal tissues. Breast cancer patients with high XPF expression have a higher relapse free survival rate (HR = 0.88, 95 % CI = 0.80-0.97), but have no effect on the overall survival rate (logrank P = 0.28). XPF -673C > T variant can reduce the risk of breast cancer patients (OR = 0.35, 95 %CI = 0.20-0.63 for codominant mode; OR = 0.66, 95 %CI = 0.51-0.85 for dominant model; OR = 0.40, 95 %CI = 0.23-0.70 for recessive model). The XPF 11985 GG genotype reduced the risk of early breast cancer (OR = 0.49, 95 %CI = 0.24-0.97), but not the risk of advanced breast cancer (OR = 1.20, 95 % CI = 0.58-2.48). XPF 11985A > G variant can also reduce the risk of ERBB2 expression in patients (OR = 0.50, 95 %CI = 0.27-0.94). There is no correlation between XPF -673C > T/XPF11985A > G variants and ER and PR. XPF -673C > T variant can reduce XPF expression (P < 0.05). CONCLUSIONS Genetic variations of XPF gene may affect its expression and the risk of breast cancer in the Chinese population.

Prognostic significance of excision repair cross complementation group 1 rs2298881 in patients with gastric cancer receiving platinum-based chemotherapy: A PRISMA-compliant meta-analysis. Medicine (Baltimore) 2021; 100:e26850. [PMID: 34414935 PMCID: PMC8376342 DOI: 10.1097/md.0000000000026850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Accepted: 07/12/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Gastric cancer (GC) is a strong cause of global cancer mortality. Nucleotide excision repair (NER) can modulate platinum-based chemotherapeutic efficacy by removing drug-produced DNA damage. Some studies have found a link between excision repair cross complementation group 1 (ERCC1) rs2298881, one gene in NER pathway, and response to chemotherapy. However, the results have been disputed. METHODS We conducted a meta-analysis to reevaluate the association between polymorphisms of NER gene (ERCC1 rs2298881) and the clinical outcomes in gastric cancer patients receiving platinum-based chemotherapy. Searching PubMed, Web of Science, EMBASE, Google Scholar, and China National Knowledge Infrastructure, 2 independent searchers found all pertinent literatures up to May 1, 2021. We enrolled studies according to consistent selection criteria, extracted and vitrified data. Crude odds ratios (ORs) and hazard ratios (HRs) with 95% confidence interval (CI) were applied to evaluate the effect of ERCC1 rs2298881 on patients treated by platinum-based chemotherapy. RESULTS By the data gathered from 6 independent studies, 1940 cases diagnosed with gastric cancer and treated with chemotherapy were included, containing 1208 Good-Responders and 732 Poor-Responders. With a comprehensive meta-analysis, we found that the patients with ERCC1 rs2298881A allele had a worse response to chemotherapy than those who with rs2298881C allele under allelic model (A vs C), with the pooled OR of 0.780 (95% CI: 0.611-0.996, P = .046). And our analysis indicated that AA genotype was associated with unfavorable overall survival (HR = 1.540, 95% CI = 1.106-2.144, P = .011) compared with CC genotype. CONCLUSIONS ERCC1 rs2298881 is suggested as a marker of clinical outcome in gastric cancer patients treated by platinum-based chemotherapy.

Abstract
Testicular cancer is an aggressive malignancy with a rising incidence rate across the globe. Testicular germ cell tumors are the most commonly diagnosed cancers, and surgical removal of the testes is often a radical necessity along with chemotherapy and radiotherapy. While seminomas are receptive to radiotherapy as well as chemotherapy, non-seminomatous germ cell tumors respond to chemotherapy only. Due to the singular nature of testicular cancers with associated orchiectomy and mortality, it is important to study the molecular basis and genetic underpinnings of this group of cancers across male populations globally. In this review, we shed light on the population pharmacogenetics of testicular cancer, pediatric and adult tumors, current clinical trials, genetic determinants of chemotherapy-induced toxicity in testicular cancer, as well as the molecular signal transduction pathways operating in this malignancy. Taken together, our discussions will help in enhancing our understanding of genetic factors in testicular carcinogenesis and chemotherapy-induced toxicity, augment our knowledge of this aggressive cancer at the cellular and molecular level, as well as improve precision medicine approaches to combat this disease.

Abstract
Background Mycoplasma bovis (M. bovis) is a highly contagious cattle pathogen spreading worldwide and especially in Ningxia Hui Autonomous Region in China. Results Two types of ST, ST10and ST134, were identified in Ningxia Hui Autonomous Region. Thirty-seven strains belonged to ST10 and 28 strains belonged to ST134. ST134 was a new ST and first found in 2009 and was only widely distributed in Ningxia Hui Autonomous Region at present. The M. bovis ST10 was widely spread in many provinces in China and was widespread in Ningxia Hui Autonomous Region since 2010. It is speculated that the prevalence of M. bovis ST10 in Ningxia Hui Autonomous Region began in 2010. Conclusions This study is the first report on the genetic diversity of M. bovis from 2009 to 2018 in Ningxia Hui Autonomous Region and provides the epidemiological information. These results may help further our understanding of the evolution of M. bovis and provide information that may be useful for the development of novel vaccines.

Abstract
OBJECTIVES Nucleotide excision repair protein expression has been claimed to be responsible for platinum-based chemotherapy resistance. ERCC1, XPF and XPA, core proteins in DNA repair, were evaluated regarding their prognostic value in patients with head and neck squamous cell carcinoma by looking at overall survival and time to recurrence. MATERIALS AND METHODS Tissue microarrays were constructed from 453 cases of HNSCC, including 222 oral (49%), 126 oropharyngeal (27.8%) and 105 laryngeal (23.2%) tumours. There were 284 XPF, 293 XPA and 294 ERCC1 specimens evaluable for protein expression analysis after immunohistochemical workup. Expression levels were dichotomised into high- and low-expressing groups. Outcomes for overall survival (OS) and time to recurrence (TTR) were analysed using the Kaplan-Meier method. RESULTS No correlation between ERCC1, XPA and XPF expression and OS was found by looking at the overall patient cohort. However, subsite analysis revealed that high ERCC1 expression was associated with a significantly inferior OS in patients with SCC of the oral cavity (p = 0.028) and showed an independent predictive value in multivariate analysis (p = 0.0123). High XPA expression showed a significantly increased OS in patients with oropharyngeal SCC (p = 0.0386). Regarding XPF, no impact on OS in any subsite could be shown. CONCLUSIONS While high ERCC1 expression functions as a predictive marker with decreased OS in patients with squamous cell carcinoma of the oral cavity, high XPA expression shows an inverse effect in the subsite of the oropharynx, which has not been described previously. CLINICAL RELEVANCE ERCC1 and XPA might be candidates to overcome chemotherapy resistance in subtypes of HNSCC.

Abstract
Correlation of xeroderma pigmentosum complementation group F (XPF) expression with gastric cancer and prognosis was investigated. We randomly selected 76 gastric cancer patients who were admitted to the Second People's Hospital of Dezhou City and received treatment, and detected XPF expression in gastric cancer tissues (observation group) and normal gastric mucosa adjacent to tumor (control group) via immunohistochemistry. Correlation between XPF expression and clinicopathological indicators of gastric cancer was verified via single-factor Chi-square test. Cox's proportional hazard regression model was used in the analysis of influencing factors of patient's prognosis, and Kaplan-Meier was used to analyze the survival rates of XPF-positive and -negative patients. In the observation group, the XPF-positive rate was significantly higher than that in the control group with a statistically significant difference (P<0.05). Single-factor analysis showed that XPF expression was correlated with the family history and Laurén classification (P<0.05). Kaplan-Meier survival analysis revealed that the survival time of XPF-positive patients was shorter than that of XPF-negative patients (P<0.05). Multifactorial analysis using Cox's hazards model suggested that XPF was an independent factor affecting the prognosis of gastric cancer (P<0.05). In conclusion, XPF expression plays an important role in the occurrence and development of gastric cancer, and a high expression of XPF suggests a poor prognosis of gastric cancer patients.

Abstract
BACKGROUND A number of studies have investigated the roles of excision repair cross-complementation group 1 (ERCC1) gene rs3212986 polymorphisms as potential biomarkers in gastric cancer (GC). However, the results were inconsistent. Here, we performed a meta-analysis to explore ERCC1 rs3212986 polymorphisms in the chemotherapy response and clinical outcome of GC. METHODS PubMed, Embase, and Web of Science were searched up to July 28, 2017, for studies on the association between ERCC1 rs3212986 A/C polymorphisms and response to chemotherapy as well as overall survival time of GC. A fixed-effect or random-effect model was used to calculate the pooled odds ratios (ORs) based on the results from the heterogeneity tests. RESULTS The result revealed that there was no significant association between the ERCC1 rs3212986 A/C polymorphism and response to chemotherapy in GC under comparison models (AA + CA versus CC, OR 0.95, P=0.80, AA versus CA, OR 0.85, P=0.55, AA versus CC, OR 0.74, P=0.47). Further identification suggested that ERCC1 rs3212986 A/C polymorphisms were not linked with the overall survival of GC (AA + CA versus CC, OR 1.09, P=0.52, AA versus CA, OR 1.05, P=0.85, AA versus CC, OR 1.43, P=0.23). CONCLUSION Our meta-analysis indicated that the ERCC1 rs3212986 A/C polymorphism was not associated with response to chemotherapy or overall survival time in GC. Well-designed studies with larger sample sizes and more ethnic groups should be performed to further validate our results.

Functional genetic variants of XRCC4 and ERCC1 predict survival of gastric cancer patients treated with chemotherapy by regulating the gene expression. Mol Carcinog 2017; 56:2706-2717.

Abstract
DNA repair protects genomic integrity and may modulate chemotherapy efficacy. Few large-scale studies have evaluated predictive roles of genetic variants of DNA repair genes in survival of Chinese gastric cancer (GCa) patients treated with chemotherapy. Here, we assessed the roles of 35 single nucleotide polymorphisms (SNPs) in DNA repair genes in survival of 1002 GCa patients, of whom 694 received chemotherapy and 308 did not. Among patients receiving chemotherapy, the ERCC1 rs2298881A allele was associated with a better survival [hazards ratio (HR) = 0.82, 95% confidence interval (CI) = 0.69-0.98; P = 0.03], whereas two XRCC4 SNPs were associated with a worse survival (HR = 1.26, 95% CI = 1.03-1.54 for the rs10040363G allele, P = 0.02; and HR = 1.30, 95% CI = 1.06-1.59 for the rs2075685T allele, P = 0.01). These three SNPs were unique survival predictors for patients treated with chemotherapy (P < 0.05 for all) but not for patients without chemotherapy (P > 0.05 for all), suggesting that they modulated chemotherapy efficacy. Patients who received chemotherapy and had haplotypes with at least one death-risk allele in XRCC4 had a poor survival, and the trend for an increase in the number of death-risk alleles adversely affecting the survival was also observed in an allelic dose-dependent manner (Ptrend = 0.001). Further functional analysis revealed that the death-risk alleles up-regulated the gene expression, leading to a worse survival as suggested by our meta-analysis pooling both mRNA microarray data from the GEO database and published data (ERCC1: HR = 1.31 [1.08-1.58]; P = 0.006). These functional genetic variants may independently or jointly affect survival in chemotherapy-treated GCa patients by modulating the gene expression in the tumors.

Abstract
Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer. The treatment of GC remains challenging as the outcomes achieved with surgery alone or adjuvant or neoadjuvant chemotherapy and radiotherapy are relatively poor. New treatment strategies are emerging and are being tested in solid tumors including GC. Over the past few years, the treatment of metastatic colorectal cancer (CRC) has made great advances, but strategies to manage GC have improved little. Multiple drug resistance is common in GC chemotherapy and targeted therapy; some patients appear to receive treatment that is suboptimal or even inefficacious. Unfortunately, there are few validated predictive biomarkers to guide the tailored treatment of GC. ToGA and AVAGAST are two phase III trials that tested the efficacy and safety of targeted agents in advanced gastric cancer (AGC), and results clearly indicated that patients need to be selected and that targeted agents are the best hope for better results. This review aims to provide an overview of potential predictive biomarkers for cytotoxic and targeted agents in GC.

Abstract
The aim of the current study was to investigate the role of polymorphisms in DNA repair pathways on the clinical outcome of gastric cancer patients treated with platinum-based chemotherapy. A total of 380 gastric cancer patients treated with platinum-based chemotherapy were included in the present study. The genotypes of ERCC1 rs11615 (Asn118Asn) and rs3212986 (*197G>T), ERCC2 rs1799793 (Asn312Asp) and rs13181 (Lys751Gln), NBN rs1805794 (Gln185Gln) and rs1063054 (*1209A>C), RAD51 rs1801321 (-61G>T) and rs12593359 (*502T>G), and XRCC3 rs861539 (Thr241Met) were determined by polymerase chain reaction-restriction fragment length polymorphism, according to the manufacturer's instructions. The TC+CC genotypes of ERCC1 rs11615 and GA+AA genotypes of ERCC2 rs1799793 were found to be associated with improved response to chemotherapy, with an adjusted odds ratio of 1.66 (95% CI, 1.07-2.56) and 1.61 (95% CI, 1.05-2.49), respectively. Based on the results of Cox analysis, patients with TC+CC genotypes of ERCC1 rs11615 and GA+AA genotypes of ERCC2 rs1799793 exhibited a significantly decreased risk of mortality, with hazard ratios of 1.71 (95% CI, 1.06-2.72) and 1.97 (95% CI, 1.28-3.03), respectively. In conclusion, these results suggest that ERCC1 rs11615 and ERCC2 rs1799793 in the DNA repair pathways may be used as predictive factors of the clinical outcome in gastric cancer patients.

Abstract
We aimed to evaluate the clinical response to platinum-based chemotherapy and treatment outcome of gastric cancer patients in the present of ERCC1, ERCC2, NBN, RAD51, and XRCC3 gene polymorphisms. A number of 415 patients of gastric cancer that received platinum-based chemotherapy were enrolled in the present study. The presence of ERCC1 rs11615 and rs2298881, ERCC2 rs1799793 and rs13181, NBN rs1805794, rs709816, and RAD51 rs1801321 and XRCC3 rs1799794 were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Conditional regression analysis identified that CC genotype of ERCC1 rs11615 and AA genotype of ERCC2 rs1799793 was associated with a better response to chemotherapy in gastric cancer patients, and the odds ratio (ORs)(95% confidence interval (CI)) were 2.70(1.33-5.70) and 3.12(1.52-6.84), respectively. By the Cox analysis, the CC genotype of ERCC1 rs11615, AA genotype of ERCC2 rs1799793, and CC genotype of NBN rs1805794 were significantly associated with a longer overall survival (OS) of gastric cancer. In conclusion, our results suggest that ERCC1 rs11615, ERCC2 rs1799793, and NBN rs1805794 polymorphisms in the DNA repair pathways may influence the response to chemotherapy and OS of gastric cancer.
