Method: we recruited 829 ESCC cases and 1,522 healthy controls to explore the correlation of tagging polymorphisms in CTLA4 gene with ESCC extensively. Results: For rs16840252 C>T, rs733618 T>C, rs3087243 G>A, and rs231775 G>A loci in CTLA4 , frequency of these genotypes in ESCC cases and controls was not different in overall comparison. Compared with rs3087243 GG in CTLA4 , we found that there were significant differences in frequency of the rs3087243 GA and rs3087243 GA/AA between ESCC cases and controls in female subgroup (GA vs. GG: adjusted OR=1.50, P =0.038; GA/AA vs. GG: adjusted OR=1.54, P =0.024). CTLA4 haplotype analysis suggested that others haplotypes could increase the risk of ESCC with 2.05-fold ( P =0.027). However, we found that locus in CTLA4 was not associated with the susceptibility of lymph node metastasis. Conclusion: Our investigation highlights that CTLA4 rs3087243 locus is associated with ESCC development in female subgroup. Polymorphism CTLA4 Esophageal cancer Susceptibility Immune check-points Introduction Esophageal cancer (EC), a lethal malignancy, is one of the leading causes of cancer-related death. It is reported that an estimated 456 thousand new EC cases and 400 thousand EC-related deaths occurred in 2012 worldwide [ 1 ]. China was the highest-risk area of EC, and the most of EC cases are esophageal squamous cell carcinomas (ESCC) [ 2 , 3 ]. The contributing risk factors of ESCC are not well known, but are considered to include tobacco use, drinking, eating at high temperatures and low intake of fruits/vegetables [ 4 – 6 ]. These identified risk factors could not explain the etiology of ESCC well. It has been thought that genetic risk factors may play important roles in the occurrence and development of ESCC. Identifications of the individual susceptible factors may be beneficial for the prevention of ESCC . Via restraining the excessive activation of T-lymphocytes, immune check-points (ICP) could make an important role to a homeostasis of immune condition and forestalling autoimmunity [ 7 , 8 ]. In addition, in the procedure of carcinogenesis, ICP mechanism could be partly activated and act as an inhibitor of anti-tumor immune, which might result in a development of cancer. Accumulating evidence of cancer treatment with ICP inhibitors (ICPIs), such as monoclonal antibody (mAb) of anti-cytotoxic T lymphocyte antigen 4 (CTLA4) and programmed cell death protein 1 (PD-1), are making an important breakthrough in cancer-related treatment strategies [ 9 ]. Several studies have reported that ICPIs, (e.g., CTLA4 inhibitors, PD-1/PD-L1 inhibitors, etc.) may be a valuable option for the treatment of advanced ESCC patients [ 10 , 11 ]. Recently, it was suggested that the single nucleotide polymorphisms (SNPs) in ICP-related genes could influence the functional of immune [ 12 ]. The association of ICP-related SNPs with the risk of ESCC have been explored widely. Cao et al. have reported that several tagging SNPs in BTLA gene, rs2171513 G > A and rs3112270 A > G variants, are candidates for an occurrence of ESCC [ 13 ]. In addition, a previous study, have suggested that one of the tagging PD-1 SNPs, rs10204525, might reduce a susceptibility to ESCC [ 14 ]. Although the relationship of CTLA4 SNPs with the risk of ESCC has been explored in the past two decades, the findings were controversial and not full-understood. Sun et al. reported that CTLA4 49G > A (rs231775) could increase the risk of ESCC with large sample sizes [ 12 ]. However, a recent study accompanied by a meta-analysis reported that CTLA4 49G > A did not influence the risk of ESCC [ 15 ]. In view of these findings, we recruited 829 ESCC cases and 1,522 healthy controls to explore the correlation of tagging polymorphisms in CTLA4 gene with ESCC extensively. Materials and methods Study populations In total, 2,351 participants as study populations were recruited, 829 cases of ESCC and 1,522 participants without any cancer history as healthy controls. The current investigation started from August 2013 till June 2018. Union Clinical Medical College of Fujian Medical University (Fujian Province, China) approved an Ethical committee clearance (No. 2017KY028). Informed consent was signed by each subject. These participants were of Chinese Han ethnicity. All participants were recruited from the Union Hospital (Fuzhou, China) and No.1 People's Hospital of Zhenjiang City (Zhenjiang, China). These ESCC cases ranged from 41 to 87 years old (mean age: 62.55 ± 8.20 years) and each ESCC patient included in this investigation was biopsy diagnosed. ESCC cases with other cancer history or those who have been treated with immunotherapy or chemotherapy/radiotherapy were excluded. All these healthy subjects included for this investigation were cancer-free and after a comprehensive exam they had no abnormal condition. These controls ranged from 38 to 92 years old (mean age: 62.94 ± 9.06 years). Two experienced authors finished a personal questionnaire by interviewing each subject. Questionnaire was harnessed for collecting the demographic information and data (e.g. sex, age, height, weight, drinking and smoking habit, etc.). Via reviewing their medical records, the pathological information of ESCC was recorded. Tagging SNPs Selecting and genotyping CTLA4 the gene was 6.2 Kbp length in chromosome 2. For tagging SNPs selection, we extended 5 Kb upstream and downstream, respectively. In total, we selected 16.2 Kbp region, which spans from 203862788 to 203878960. Using haploview 4.2 software, we selected four tagging SNPs. The detailed method for SNP selecting have been mentioned in previous studies [ 12 , 16 ]. Finally, rs16840252 C > T, rs733618 T > C, rs3087243 G > A, and rs231775 G > A loci in CTLA4 gene were selected. After an overnight fast, each subject donated a blood sample. Intravenous blood was collected in a tube, which was preloaded with ethylenediamine tetraacetic acid-anticoagulated. Genomic DNA of each participant was isolated using a Promega DNA Kit (Promega, Madison, USA). Genotypes of the rs16840252, rs733618, rs3087243, and rs231775 loci in CTLA4 were determined by a SNPscan Kit [ 17 , 18 ]. This PCR method was carried out by using a double ligation and multiplex fluorescence [ 19 ]. Ninety-four samples were selected for quality control. We analyzed the genotype of the rs16840252, rs733618, rs3087243, and rs231775 loci in CTLA4 again. The obtained genotypes of CTLA4 loci were not changed. Statistical analysis The rs16840252, rs733618, rs3087243, and rs231775 genotype frequencies were compared in four genetic models. Hardy-Weinberg equilibrium (HWE) was tested by using an online χ 2 -test software ( http://ihg.gsf.de/cgi-bin/hw/hwa1.pl ). BMI was calculated by using height, weight. And according to the Chinese criterion for overweight and obesity [ 20 , 21 ], BMI ≥ 24 kg/m 2 was considered as the cut-off point. For a correlation analysis, we used χ 2 -test to assess the difference of genotype frequencies between two groups. Regarding the included risk variables, including sex, age, BMI, drinking and smoking habit, the relationship of rs16840252, rs733618, rs3087243, and rs231775 loci in CTLA4 with the ESCC occurrence was determined with a multivariate logistic regression analysis. Odds ratios (ORs) and 95% confidence intervals (CIs) were harnessed to assess the potential relationship. The findings were calculated by using a SAS version 9.4 software (SAS Institute, Cary, NC). A P < 0.05 was adopted for the level of statistical significance. Results Demographic characteristics Among the 829 cases with ESCC, 638 were males (76.96%) and 191 were females (23.04%). We recruited 1,522 healthy controls, including 1,144 males (75.16%) and 378 females (24.84%). Among the 829 ESCC cases, 391 were < 63 years (47.1%) and 438 were ≥ 63 (52.83%). Among 1,522 healthy controls, 750 subjects were < 63 years (49.28%) and 772 subjects were ≥ 63 (50.72%). As listed in Table 1 , these conditions indicated that age and sex were well-matched between two groups ( P ≥ 0.05). However, the differences of BMI, drinking and smoking habit were significant ( P < 0.001).

For rs3087243, frequency of rs3087243 GG genotype in ESCC cases and controls was 62.78% and 66.27%, respectively. When rs3087243 GG in CTLA4 was used as reference, null correlation was identified between ESCC susceptibility and rs3087243 AA (OR = 1.34; P = 0.188), rs3087243 GA (OR = 1.14; P = 0.154) and rs3087243 GA/AA (OR = 1.17; P = 0.093). When rs3087243 GG/GA in CTLA4 was used as reference, null correlation was also identified between ESCC susceptibility and rs3087243 AA (OR = 1.28; P = 0.260). Regarding the included risk variables, including sex, age, BMI, drinking and smoking habit, a multivariate logistic regression analysis was conducted to determine the relationship of rs3087243 loci in CTLA4 with the ESCC occurrence. We also suggested that no correlation was identified between ESCC susceptibility and rs3087243 genotypes (Table 3 ). Risk variables could influence the relationship of loci in CTLA4 with ESCC risk. Here, we conducted subgroup analyses for sex, age, BMI, drinking and smoking habit. Compared with rs3087243 GG in CTLA4 , we found that there were significant differences in frequency of the rs3087243 GA and rs3087243 GA/AA between ESCC cases and controls in female subgroup (GA vs. GG: adjusted OR = 1.50, P = 0.038; GA/AA vs. GG: adjusted OR = 1.54, P = 0.024, Table 4 ).

In addition, in subgroup analyses, there were no difference in distribution of rs16840252, rs733618, and rs231775 genotype between the ESCC cases and controls (data not shown). CTLA4 gene haplotypes Using SHESIS program (Bio-X Inc., Shanghai, China, http://27.223.74.230:8099/myAnalysis.php ) [ 22 ], five CTLA4 haplotypes were constructed (Table 5 ). If the haplotype was less than 1%, it was combined in others. It suggested that the other haplotypes might be associated with an increased risk of ESCC.

Discussion Recent studies have indicated that the role of heredity factors could play a vital influence in an occurrence of tumor. Fang et al. carried out a systemic review and meta-analysis with larger sample size and found that CTLA4 rs231775 and rs3087243 may be related to an increased risk of cancer [23]. However, they could not identify an association of CTLA4 rs733618 with the development of cancer [23]. In this study, we have suggested that CTLA4 rs3087243 variants, in female subgroup, also increased the risk of ESCC. In addition, we also found that other haplotypes might be associated with an increased risk of ESCC. To our knowledge, our investigation was the first literature to determine the relationship of tagging polymorphisms in CTLA4 gene withthe occurrence of ESCC. Rs3087243 is a common locus in CTLA4 gene, which locate in a 3’-UTR region [24]. In the present study, when subgroup analysis was conducted by different gender, an association of rs3087243 (CTLA4 60 G/A) polymorphism with the increased susceptibility was found. Beissert et al. suggested that CTLA4 may be implicated in UV-induced immunosuppression and promote an occurrence of malignancy [25]. The G allele of rs3087243 could reduce the CTLA4 expression of CD4 + T lymphocytes on membrane [26]. Recently, some pooled-analysis have indicated that CTLA4 rs3087243 polymorphism may increase the susceptibility of cancer [23, 27].In our investigation, the correlation of CTLA4 rs3087243 locus with risk to ESCC was significant in female subgroup was established, which was similar to the findings mentioned above. However, these observations might be explained with caution. These findings for the potential correlation of CTLA4 rs3087243 locus with risk to ESCC were based on moderate samples. In the future, investigations with more participants are needed to verify our findings. There were some limitations in our investigation. Firstly, for the recruited participants were from hospitals, bias could have happened. Secondly, this study enrolled less smoking and drinking individuals and more overweight/obesity subjects in controls, so we did not full-matched these risk factors. Thirdly, the subgroup about ever drinking only included a relatively small participants, which might lead to an inaccurate assessment. Our investigation should be checked in a larger sample sizes with various risk factors (e.g., physical exercise, energy intake, smoking and drinking etc.) in retrospective and prospective cohorts. Fourth, we only found a haplotype could increase the risk of ESCC with 2.05-fold, which only influenced less 1% populations. Fifth, the distribution of CTLA4 rs16840252 C>T genotypes violated HWE. Finally, we only focused on the association of CTLA4 SNPs with the risk of ESCC. And other gene variants of costimulatory molecules should not be ignored. In conclusion, to our knowledge, this investigation is the first study focused on the relationship of CTLA4 tagging loci with risk to ESCC. And a significant correlation of ESCC development with CTLA4 rs3087243 locus in female subgroup is found, which indicates additional scan for a potential role of CTLA4 tagging loci in the etiology of ESCC.

It is reported that an estimated 456 thousand new EC cases and 400 thousand EC-related deaths occurred in 2012 worldwide [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. China was the highest-risk area of EC, and the most of EC cases are esophageal squamous cell carcinomas (ESCC) [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e, \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. The contributing risk factors of ESCC are not well known, but are considered to include tobacco use, drinking, eating at high temperatures and low intake of fruits/vegetables [\u003cspan additionalcitationids=\"CR5\" citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. These identified risk factors could not explain the etiology of ESCC well. It has been thought that genetic risk factors may play important roles in the occurrence and development of ESCC. Identifications of the individual susceptible factors may be beneficial for the prevention of ESCC .\u003c/p\u003e \u003cp\u003eVia restraining the excessive activation of T-lymphocytes, immune check-points (ICP) could make an important role to a homeostasis of immune condition and forestalling autoimmunity [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]. In addition, in the procedure of carcinogenesis, ICP mechanism could be partly activated and act as an inhibitor of anti-tumor immune, which might result in a development of cancer. Accumulating evidence of cancer treatment with ICP inhibitors (ICPIs), such as monoclonal antibody (mAb) of anti-cytotoxic T lymphocyte antigen 4 (CTLA4) and programmed cell death protein 1 (PD-1), are making an important breakthrough in cancer-related treatment strategies [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Several studies have reported that ICPIs, (e.g., CTLA4 inhibitors, PD-1/PD-L1 inhibitors, etc.) may be a valuable option for the treatment of advanced ESCC patients [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eRecently, it was suggested that the single nucleotide polymorphisms (SNPs) in ICP-related genes could influence the functional of immune [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. The association of ICP-related SNPs with the risk of ESCC have been explored widely. Cao \u003cem\u003eet al.\u003c/em\u003e have reported that several tagging SNPs in \u003cem\u003eBTLA\u003c/em\u003e gene, rs2171513 G\u0026thinsp;\u0026gt;\u0026thinsp;A and rs3112270 A\u0026thinsp;\u0026gt;\u0026thinsp;G variants, are candidates for an occurrence of ESCC [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e].

indicated that the role of heredity factors could play a vital influence in an occurrence of tumor. Fang \u003cem\u003eet al.\u003c/em\u003e carried out a systemic review and meta-analysis with larger sample size and found that \u003cem\u003eCTLA4\u003c/em\u003e rs231775 and rs3087243 may be related to an increased risk of cancer [23]. However, they could not identify an association of \u003cem\u003eCTLA4\u003c/em\u003e rs733618 with the development of cancer [23]. In this study, we have suggested that \u003cem\u003eCTLA4\u003c/em\u003e rs3087243 variants, in female subgroup, also increased the risk of ESCC. In addition, we also found that other haplotypes might be associated with an increased risk of ESCC. To our knowledge, our investigation was the first literature to determine the relationship of tagging polymorphisms in \u003cem\u003eCTLA4\u003c/em\u003e gene withthe occurrence of ESCC.\u003c/p\u003e\n\u003cp\u003eRs3087243 is a common locus in \u003cem\u003eCTLA4\u003c/em\u003e gene, which locate in a 3\u0026rsquo;-UTR region [24]. In the present study, when subgroup analysis was conducted by different gender, an association of rs3087243 (CTLA4 60 G/A) polymorphism with the increased susceptibility was found. Beissert\u003cem\u003e\u0026nbsp;et al.\u003c/em\u003e suggested that \u003cem\u003eCTLA4\u003c/em\u003e may be implicated in UV-induced immunosuppression and promote an occurrence of malignancy [25]. The G allele of rs3087243 could reduce the CTLA4 expression of CD4\u003csup\u003e+\u003c/sup\u003e T lymphocytes on membrane [26]. Recently, some pooled-analysis have indicated that \u003cem\u003eCTLA4\u003c/em\u003e rs3087243 polymorphism may increase the susceptibility of cancer [23, 27].In our investigation, the correlation of \u003cem\u003eCTLA4\u003c/em\u003e rs3087243 locus with risk to ESCC was significant in female subgroup was established, which was similar to the findings mentioned above. However, these observations might be explained with caution. These findings for the potential correlation of \u003cem\u003eCTLA4\u003c/em\u003e rs3087243 locus with risk to ESCC were based on moderate samples. In the future, investigations with more participants are needed to verify our findings.\u003c/p\u003e\n\u003cp\u003eThere were some limitations in our investigation. Firstly, for the recruited participants were from hospitals, bias could have happened. Secondly, this study enrolled less smoking and drinking individuals and more overweight/obesity subjects in controls, so we did not full-matched these risk factors. Thirdly, the subgroup about ever drinking only included a relatively small participants, which might lead to an inaccurate assessment. Our investigation should be checked in a larger sample sizes with various risk factors (e.g., physical exercise, energy intake, smoking and drinking etc.) in retrospective and prospective cohorts. Fourth, we only found a haplotype could increase the risk of ESCC with 2.05-fold, which only influenced less 1% populations. Fifth, the distribution of \u003cem\u003eCTLA4\u003c/em\u003e rs16840252 C\u0026gt;T genotypes violated HWE. Finally, we only focused on the association of \u003cem\u003eCTLA4\u003c/em\u003e SNPs with the risk of ESCC. And other gene variants of costimulatory molecules should not be ignored.\u003c/p\u003e\n\u003cp\u003eIn conclusion, to our knowledge, this investigation is the first study focused on the relationship of \u003cem\u003eCTLA4\u003c/em\u003e tagging loci with risk to ESCC. And a significant correlation of ESCC development with \u003cem\u003eCTLA4\u003c/em\u003e rs3087243 locus in female subgroup is found, which indicates additional scan for a potential role of \u003cem\u003eCTLA4\u003c/em\u003e tagging loci in the etiology of ESCC.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cp\u003eESCC: esophageal squamous cell carcinomas; CTLA4: Cytotoxic T-lymphocyte antigen-4; ICP: immune check-points; ICPIs: ICP inhibitors; mAb: monoclonal antibody; PD-1: programmed cell death protein 1; SNPs: single nucleotide polymorphisms; BMI: body mass index; HWE: Hardy-Weinberg equilibrium; ORs: Odds ratios; CIs: confidence intervals\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eAuthor contribution statement:\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eConceived and designed the experiments:\u0026nbsp;ZH, SC\u003cbr\u003e\u0026nbsp;Performed the experiments: WT, JW, CL, HQ\u003cbr\u003e\u0026nbsp;Analyzed the data: WT, JW\u003c/p\u003e\n\u003cp\u003eContributed reagents/materials/analysis tools:\u0026nbsp;ZH, SC\u003cbr\u003e\u0026nbsp;Wrote the manuscript:\u0026nbsp;WT, JW, CL\u003c/p\u003e\n\u003cp\u003eOther (please specify): None\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAcknowledgements:\u0026nbsp;\u003c/strong\u003eWe appreciate all subjects who participated in this study.We wish to thank Dr. Yan Liu\u0026nbsp;(Genesky Biotechnologies Inc., Shanghai, China) for technical support.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDisclosure of Potential Conflicts of Interests:\u003c/strong\u003e The authors have no potential financial conflicts of interest.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eData Access Statement:\u003c/strong\u003e The research data supporting this publication are available in the online material.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eEthics Statement:\u0026nbsp;\u003c/strong\u003eAll procedures performed in this study involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards.
