[PMID: 32981864 DOI: 10.1016/j.oooo.2020.08.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 06/04/2020] [Accepted: 08/02/2020] [Indexed: 12/27/2022]
Abstract
OBJECTIVES Tissue hypoxia in oral submucous fibrosis (OSMF) induces hypoxia-inducible factor (HIF)-1 α and vascular endothelial growth factor (VEGF), causing angiogenesis. Single nucleotide polymorphisms (SNPs) may predict susceptibility to environmental carcinogens and to development of OSMF, as well as its severity and malignant transformation. This study aimed to determine the serologic levels and frequencies of SNPs of HIF-1 α and VEGF in OSMF. STUDY DESIGN In this prospective pilot study, the frequencies of SNPs of HIF-1 α (C1772 T, G1790 A); VEGF-A 936 C/T; and VEGF-C (rs7664413, rs1485766) in patients with OSMF or oral squamous cell carcinoma (OSCC) and in healthy controls were determined by using polymerase chain reaction (PCR) (n = 100 each), and serologic levels were determined by using enzyme-linked immunosorbent assay (ELISA (n = 50 each), in a North Indian population. RESULTS Heterozygous forms of HIF-1 α C1772 T (CT: odds ratio [OR] 5.0; 95% confidence interval [CI] 2.24-11.16; P < .001); HIF-1 α G1790 A (GA: OR 2.8; 95% CI 1.62-5.16; P < .001); and VEGF-C rs1485766 (AC: OR 2.18; 95% CI 1.19-3.99; P < .05) were associated with OSMF. The mean serologic levels of HIF-1 α, VEGF-A, and VEGF-C were significantly raised in patients with OSMF compared with healthy controls (P < .001). CONCLUSIONS The SNPs of HIF-1 α, VEGF-A, and VEGF-C and their serologic levels can act as prognostic biomarkers and aid in the development of specialized anti-HIF-1 α or anti-VEGF drugs for the management and prevention of OSCC in patients with OSMF.

Abstract
OBJECTIVE Vascular endothelial growth factor (VEGF) is a potent endothelial cell mitogen that plays a vital role in angiogenesis, tumor growth, and metastasis. The associations between 3 polymorphisms of VEGF (+936 C > T, -2578 C > A, and -460 C > T) and ovarian cancer (OC) risk have been extensively investigated, but the currently available results are inconsistent. To obtain a more accurate estimation of the association, a meta-analysis was conducted in this study. METHODS PubMed, Cochrane Library, Embase, and Chinese National Knowledge Infrastructure were searched for all relevant studies published before November 30, 2014. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for the VEGF polymorphisms to assess the strength of the association. RESULTS With regard to the +936 C > T polymorphism, 5 articles were available for analysis (882 cases and 1155 controls), whereas for -2578 C > A (559 cases and 632 controls) and -460 C > T (350 cases and 409 controls), only 2 articles were eligible for analysis, respectively. A significant association between the VEGF +936 C/T polymorphism and OC was demonstrated in white populations (CT vs CC: OR, 0.638 [95% CI, 0.437-0.932; P = 0.020]; TT + CT vs CC: OR, 0.694 [95% CI, 0.483-0.995; P = 0.047]). No relationship was found between -2578 C > A and -460 C > T and susceptibility to develop OC. CONCLUSIONS This meta-analysis provides supportive evidence that the VEGF +936 C/T polymorphism may influence the risk for the development of OC in a protective model among whites.

Abstract
Background To investigate whether VEGF polymorphisms (-460T/C, +405G/C, and +936C/T)/haplotypes influence the susceptibility of obstructive sleep apnea (OSA). Method A prospective case-control study was conducted to evaluate the genetic effects of VEGF polymorphisms on the development of OSA. 150 patients and 225 healthy controls were recruited for this study and their genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). The odds ratios (OR) and 95% confidence intervals (CI) were calculated by logistic regression analysis. Result Our study showed that the -460C allele (C vs. T: OR = 1.95, 95% CI = 1.38–2.76) and +936T allele (T vs. C: OR = 1.48, 95% CI = 1.02–2.15) were associated with an increased OSA risk, whereas +405C allele was associated with a decreased susceptibility to OSA (C vs. G: OR = 0.61, 95% CI = 0.45–0.83). Compared with the most common haplotype CCT, CGC (OR = 2.22, 95% CI = 1.19–4.13) and TGC (OR = 3.83, 95% CI = 1.56–9.40) were associated with a significantly increased risk of OSA. Conclusion These observations implied that VEGF gene polymorphisms might be associated with the susceptibility to OSA. These results need to be validated by other independent studies, especially in diverse ethnic populations.

Abstract
The present study aimed to evaluate whether circulating C-reactive protein (CRP) levels are a biomarker of systemic inflammation and a significant predictor of future chronic obstructive pulmonary disease (COPD) outcome. During the study, 116 patients with stable COPD and 35 age- and gender-matched healthy subjects with normal pulmonary function were observed. Patient follow-up was also performed to evaluate the strength of the associations between CRP levels and future outcomes. The observations from the present study showed that serum CRP levels were significantly higher in stable COPD patients than in control subjects (4.48±0.83 vs. 1.01±0.27 mg/l, respectively; P<0.05). In addition, it was identified that a serum CRP concentration of >3 mg/l is a poor prognostic variable of COPD compared with a CRP concentration of ≤3 mg/l [hazard ratio (HR), 2.71; 95% confidence interval (CI), 1.05–6.99; P<0.05]. A quantitative synthesis of four studies including 1,750 COPD patients was performed and statistically similar results were obtained (HR, 1.54; 95% CI, 1.14–2.07; P<0.01). The present study showed that circulating CRP levels are higher in stable COPD patients and, therefore, may be used as a long-term predictor of future outcomes. These observations highlight the importance of high sensitivity CRP assays in patients with stable COPD.

Abstract
UNLABELLED Vascular endothelial growth factor (VEGF) is a major regulator of angiogenesis in the process of tumor growth and metastasis. In present study, we conducted a case-control study and meta-analysis to evaluate the genetic effects of VEGF -634G/C and VEGF -2578C/A polymorphisms and risk of lung cancer. A total of 175 subjects were recruited for case-control study and seven studies were included in the meta-analysis. Our case-control study showed that VEGF -634G/C polymorphism had no association with lung cancer risk (CC vs. GG: OR = 0.88, 95% CI = 0.37-2.11), whereas there was an association between VEGF -2578CC genotype and decrease in lung cancer risk (CC vs. CA/AA OR = 0.52, 95% CI = 0.28-0.96). A meta-analysis was further performed and statistically similar results were obtained (CC vs. GG: OR = 0.91, 95% CI = 0.60-1.39 for VEGF -634; CC vs. AA: OR = 0.53, 95% CI = 0.32-0.89 for VEGF -2578). Our study showed that the variant genotypes of the VEGF -2578C/A polymorphism, but not the VEGF -634G/C polymorphism, was associated with lung cancer risk. More studies are needed to detect VEGF -634G/C and VEGF -2578 polymorphisms and their association with lung cancer in different ethnic populations incorporated with environmental exposures.

Abstract
Many studies have examined the association between the VEGF +936C/T (rs833061) and +460C/T (rs3025039) gene polymorphisms and oral cancer risk in various populations, but their results have been inconsistent. To assess this relationship more precisely, we performed a meta-analysis. The PubMed, Embase, Web of Science, and China National Knowledge Infrastructure databases were searched for case-control studies that were published up to January 2013. Data were extracted and pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated. Ultimately, six studies were included, comprising 1006 oral cancer cases and 1016 controls. Overall, the pooled OR for VEGF +936 T allele carriers (TC + TT) versus the wild-type homozygotes (CC) was 1.28 (95 % CI 1.04-1.58; P = 0.228 for heterogeneity), the pooled OR for TT versus CC was 1.64 (95 % CI 1.34-1.98; P = 0.315 for heterogeneity), and the pooled OR for the T allele versus the C allele was 1.42 (95 % CI 1.22-1.76; P = 0.286 for heterogeneity). In the stratified analysis by ethnicity, significant risks were found among Caucasians but not Asians. However, there were no associations between VEGF +460C/T and oral cancer risk in only two of the included studies. In conclusion, this meta-analysis demonstrates that the VEGF +936 T allele may be associated with an increased risk of oral cancer, especially among Caucasian populations.

Abstract
Background Several studies have been conducted in recent years to evaluate the risk of type 2 diabetes mellitus (T2DM) and polymorphisms of interleukin (IL)-10. However, the results remain conflicting rather than conclusive. This meta-analysis aimed to summarize the current evidence from case-control studies that evaluated this association. Methods We carried out a search in Medline, EMBASE, and the Chinese National Knowledge Infrastructure (CNKI) database for relevant studies. Data were extracted using a standardized form and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of the association. Results 10 studies were included in our meta-analysis and systemic review. Our meta-analysis indicated that IL-10 −1082A/G polymorphism was associated with the risk of T2DM (GA vs. AA: OR = 1.21, 95% CI = 1.03–1.14; GA/GG vs. AA: OR = 1.22, 95% CI = 1.05–1.41), whereas there was no association between IL-10 −592C/A (CC/CA vs. AA: OR = 1.07, 95% CI = 0.59–1.93) or -819C/T (CC/CT vs. TT: OR = 0.93, 95% CI = 0.49–1.75) polymorphism and T2DM risk was found in our study. Conclusions This meta-analysis provides strong evidence that IL-10 −1082A/G polymorphism associated with risk of T2DM. However, no association of the IL-10 −592C/A or −819C/T polymorphism with T2DM risk was found. Additional well-designed large studies were required for the validation of our results.

Abstract
Objectives The pathogenesis of age-related macular degeneration (AMD) remains unknown. Vascular endothelial growth factor (VEGF) is an important regulator of angiogenesis and a target for inhibition therapy in wet AMD. This study investigated the association between the VEGF +936 C/T gene polymorphism and AMD, in a Chinese Han population. Methods Patients with AMD, and age- and sex-matched controls were enrolled. Restriction fragment length polymorphism was used to analyse the VEGF +936 polymorphism in the promoter and the 3′ untranslated region of the gene. Results The study included 200 AMD patients and 200 control subjects. There was a significantly higher prevalence of the TT genotype among AMD patients (9.0%) compared with controls (3.5%); the odds ratio for this genotype in AMD patients was 2.73 (95% confidence intervals 1.11, 6.68). There were no significant associations between any genotype and AMD subphenotypic categories (early, geographic atrophy, choroidal neovascularization). Conclusions The present study findings suggested that the VEGF +936 TT genotype was associated with AMD among Han Chinese patients.

Abstract
Vascular endothelial growth factor (VEGF) is a major regulator of angiogenesis in the process of tumor growth and metastasis. Different VEGF gene polymorphisms have been shown to result in different VEGF protein expression in cancer cells and tumor angiogenic activity. We conducted a case-control study to evaluate the genetic effects of VEGF-460C/T polymorphism on the development of lung cancer. One hundred and twenty-six lung cancer patients and 160 sex-, age-, and ethnic-matched healthy controls were recruited for this study. The genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Odds ratios (ORs) and 95 % confidence intervals (CI) were calculated by logistic regression analysis. Our study showed that the TT genotype was associated with increased lung cancer risk than those with the CC (OR = 1.99, 95 % CI 1.05-3.77) or CT/CC (OR = 1.89, 95 % CI 1.17-3.06) genotype. Moreover, it was observed that the TT genotype associated with the advanced stage among lung cancer patients (TT vs. CC: OR = 3.09, 95 % CI 1.10-8.66). More studies are needed to detect VEGF-460C/T polymorphism and its association with lung cancer in different ethnic populations incorporated with environmental exposures.

Abstract
The vascular endothelial growth factor-A (VEGF-A) plays an important role in the angiogenesis and prognosis for gastric cancer. In addition, several single-nucleotide polymorphisms (SNPs) in VEGF-A have been shown to affect gene expression and process of angiogenesis. The present study evaluated the correlations between SNPs in VEGF-A and gastric cancer survival. Formalin-fixed paraffin-embedded tissues of 404 gastric cancer patients and blood samples from 404 controls were included in the study. The SNPs -460T/C (rs833061), +405G/C (rs2101963), -7C/T (rs25648) and +936C/T (rs3025039) were genotyped by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. We showed patients carrying the +405GG genotype had significantly worse survival in the N0 (lymph-node negative), N0L0 (lymph-node negative and lymphovascular-invasion negative) and TNM stage I-II subgroups (P = 0.021, P = 0.007 and P = 0.017, respectively). In addition, haplotype -460T/+405G/-7C and -460C/+405G/-7C carriers showed poor survival in the N0, N0L0 and TNM stage I-II subgroups (P = 0.004, P = 0.030 and P = 0.009 for TGC; P = 0.033, P = 0.049 and P = 0.011 for CGC). Overall, the +405 GG genotype or TGC and CGC haplotypes were correlated with poor survival in TNM stage I-II gastric cancer patients. The +405G/C polymorphism of VEGF-A could be used as a biomarker for molecular staging in stage I-II gastric cancer in Northern China.

Vascular endothelial growth factor (VEGF) and its receptor kinase insert domain-containing receptor (KDR) play crucial roles in angiogenesis, which contributes to the development and progression of solid tumors. The aim of this study was to investigate the associations of VEGF (-2578C > A, -1154G > A, -634G > C, and 936C > T) and KDR (-604T > C and 1192G > A) polymorphisms with the development of colorectal cancer (CRC). A total of 882 participants (390 CRC patients and 492 controls) were enrolled in the study. The genotyping of VEGF and KDR polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism assay. We found that the CT and TT genotype of the 936C > T was associated with an increased risk of CRC compared with the CC genotype as the dominant model for the T allele. In addition, we also found a increased CRC risk with TC + CC genotype of KDR -604T > C compared with TT genotype in CRC patients and control subjects. Similarly, KDR 1192G > A also showed significant association between 1192G > A variants and risk of CRC. In the haplotype analyses, haplotype -2578A/-1154A/-634G/936T of VEGF polymorphisms and haplotype -604C/1192G and -604C/1192A of KDR polymorphisms were associated with an increased susceptibility of CRC. Our results suggest that the VEGF 936C > T, KDR -604T > C, and KDR 1192G > A polymorphisms may be contribute to CRC risk in the Korean population.

Prognostic significance of vascular endothelial growth factor gene polymorphisms in patients with colorectal cancer. Int J Clin Oncol 2012; 18:1032-41.

Abstract
BACKGROUND Angiogenesis plays an important role in tumor development, progression, and metastasis. Vascular endothelial growth factor (VEGF) is a key regulator of angiogenesis. However, the contribution of common VEGF polymorphisms to colorectal cancer (CRC) prognosis remains unclear. METHODS We have genotyped four polymorphisms of VEGF (-2578C>A, -1154G>A, -634G>C, and 936C>T) in 350 CRC cases from the Korean population. The genotyping of VEGF polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS Although not every VEGF polymorphism was significantly correlated with patient prognosis in overall 350 CRC patients, we found that the VEGF -2578CA genotype was associated with a significantly poor prognosis for rectal cancers compared to the CC genotype (HR = 2.156; 95 % CI 1.090-4.267; P = 0.028). In addition, we found that the -2578A/-1154G/-634G/+936C haplotype was significantly associated with a decreased overall survival (OS) rate in all 350 CRC patients (HR = 2.530; 95 % CI 1.340-4.780; P = 0.004). In combination analysis, we found that the combined VEGF -2578CA+AA/-1154GG genotype was associated with a poor OS rate in all 350 CRC patients (HR = 2.068; 95 % CI 1.159-3.693; P = 0.015). CONCLUSIONS The VEGF gene polymorphisms investigated in this study were not found to be independent prognostic markers in Korean CRC populations. However, our results suggest that the VEGF -2578C>A variant may be a potential genetic marker for rectal cancer prognosis. Further large population studies are warranted to define whether the -2578C>A polymorphism is a prognostic marker of rectal cancer.

Abstract
Colorectal cancer (CRC) constitutes one of the most common malignancies in the world and, despite advances in diagnostics and treatments, patients still face a poor prognosis and a more individualized treatment approach appears necessary. The VEGF system and angiogenesis are involved in many aspects of tumor biology and the efficacy of chemotherapy, and some targeted therapeutics appear to be related to the function of these processes. There are many reasons why genetic variations are optimal biomarkers and in relation to the VEGF system may prove to be of clinical relevance. This review evaluates the literature on SNPs in relation to the risk of CRC and the possible prognostic and predictive value and argues for the role of these biomarkers in the future treatment of patients with CRC.

VEGF -634C/G genotype is predictive of long-term survival after treatment with a definitive 5-fluorouracil/cisplatin-based chemoradiotherapy in Japanese patients with esophageal squamous cell carcinoma. Int J Med Sci 2012; 9:833-7. [PMID: 23155356 PMCID: PMC3498747 DOI: 10.7150/ijms.4914] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2012] [Accepted: 10/15/2012] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND Reports have been accumulating that genetic properties are predictive of clinical response after and/or toxicity during cancer chemotherapy, but little information is available concerning effects on long-term survival. In this study, 49 Japanese patients with esophageal squamous cell carcinoma (ESCC) were followed up for 5 years after treatment with a definitive 5-fluorouracil (5-FU)/cisplatin (CDDP)-based chemoradiotherapy (CRT), and the effects of genotypes of vascular endothelial growth factor (VEGF) were retrospectively revaluated in terms of prediction of long-term survival. METHODS A course consisted of the continuous infusion of 5-FU at 400 mg/m(2)/day for days 1-5 and 8-12, the infusion of CDDP at 40 mg/m(2)/day on days 1 and 8, and radiation at 2 Gy/day on days 1 to 5, 8 to 12, and 15 to 19, with a second course repeated after a 2-week interval. The VEGF genotypes -1498T/C, -1154G/A, -634C/G, -7C/T, 936C/T, and 1612G/A were evaluated. RESULTS The complete response (CR) rate was 46.9% (23/49). The 5-year survival rate was 42.9 % (21/49). There were 7 patients with a CR, but survival of less than 5 years. They died from myocardial infarction (N=1), sudden cardiac death after suffering from heart failure (N=1), acute myeloid leukemia that developed from myelodysplastic syndromes (N=1), factors not specified (N=2), oropharynx cancer (N=1), and tongue cancer (N=1). VEGF -634C/G had no effect on clinical response, but long-term survival depended on the genotype (p=0.033, Fisher's; p=0.038, Cochran-Armitage; p=0.079, Log-rank). The genotype frequency of 7 patients with a CR, but survival of less than 5 years was different from that for the other 42 patients (p=0.032, Fisher's). None of the other 5 genotypes evaluated affected either clinical response or survival. CONCLUSIONS VEGF -634C/G is possibly predictive of long-term survival after treatment with a definitive 5-FU/CDDP-based CRT. Further clinical studies with a larger number of cases are needed to clarify the effects of this genotype.
