Abstract
BACKGROUND: Genetic and environmental factors play an important role in the pathogenesis of colorectal cancer. Angiogenesis is a central process in carcinogenesis and is affected by vascular endothelial growth factor (VEGF). Several genetic variations, such as polymorphism, may alter VEGF expression and influence the risk of colorectal cancer.
AIM: The objective of this study was to determine the association between VEGF gene polymorphism -634G>C and risk of colorectal cancer.
METHODS: A cross-sectional study was conducted at Haji Adam Malik general hospital and its sister hospitals. Subjects were obtained by consecutive sampling. Inclusion criteria for case and control groups were patients with colorectal cancer and healthy subject, respectively, aged 18 years or older and willing to participate in the study. Exclusion criteria were patients with systemic comorbidities or malignancies in other organs. Each subject undergoes an interview, colonoscopy, biopsy, serum VEGF level measurement, and VEGF polymorphism -634G>C evaluation.
RESULTS: Eighty subjects were enrolled and distributed into case and control groups. Males were dominant in both groups, with a mean age of older than 55 years. Most lesions were in the rectum and 45% of subjects had moderately differentiated cancer. The median serum VEGF level in the case group was higher than the control group (2,175.1 pg/mL vs. 253 pg/mL; p < 0.001). VEGF gene polymorphism -634G > C was associated with the risk of colorectal cancer (p = 0.048). GG and GC genotypes had 1.89 times higher risk of colorectal cancer compared to the CC genotype. GG genotype and G allele had the highest serum VEGF levels.
CONCLUSION: There is an association between VEGF gene polymorphism -634G>C and risk of colorectal cancer in this study.

Abstract
Background DAL-1 gene was reported to inhibit proliferation, migration, invasion, and epithelial to mesenchymal transition (EMT) of gastric cancer (GC) cells in our previous study. The association between the genomic variants in DAL-1 gene with risk of GC is still unclear. Methods In this study, 505 GC cases and 544 healthy controls (HCs) were collected to evaluate the association between six single nucleotide polymorphisms (SNPs) (rs7240736, rs73937194, rs3817466, rs8082898, rs73381527, rs9953490) of DAL-1 gene and GC risk in the Han population in Northeast China. Results The TA + AA genotypes of rs9953490 were significantly associated with an increased risk in N3 compared with N0 subgroup (adjusted OR = 4.56, 95% CI = 1.49–13.98, P = 0.008), and also showed evident association with an increased risk in TNM stage III compared with stage I-II (adjusted OR = 2.33, 95% CI = 1.16–4.67, P = 0.017). Conclusion The rs9953490 of DAL-1 gene may play an important role in the occurrence and development of GC in the Han population in Northeast China.

Abstract
Background: We aimed to evaluate the association between the vascular endothelial growth factor (VEGF) gene +936C>T polymorphism and digestive system tumors using a meta-analysis. Methods: Studies of the association between the VEGF+936C>T polymorphism and digestive system tumors published before December 2019 were searched in PubMed, EMBASE, Web of Sciences, the Chinese Biological and Medical Database (CBM), and the China National Knowledge Infrastructure (CNKI). The odds ratio and the corresponding 95% confidence interval were used as the effect indicators. A meta-analysis of original data was performed with different genetic models using the Stata 13.0 software. The reliability of the association was evaluated using the heterogeneity test, sensitivity analysis, false-positive report probability (FPRP), and bias test. Results: This meta-analysis included 37 publications with a total of 8568 digestive system tumor patients and 10,870 cases in the control populations. The overall combined analyses showed that the VEGF+936C>T gene polymorphism was significantly correlated with digestive system cancer susceptibility with the T allele increasing the risk of digestive system cancers. A stratified analysis based on ethnicity showed that the VEGF+936C>T gene polymorphism significantly increased the risk of digestive system tumors in both Asian and Caucasian populations. Additional stratified analyses based on tumor type showed that the VEGF +936C>T gene polymorphism was associated with colorectal cancer, oral cancer, and esophageal cancer. The sensitivity analysis (p < 0.2) and FPRP results also confirmed the reliability of these associations. Conclusions: This meta-analysis supported previous findings that the VEGF +936C>T gene polymorphism is significantly associated with an increased risk of the development of digestive system malignant tumors. This association still requires large-scale epidemiological studies for further validation.

Abstract
The relationship between vascular endothelial growth factor gene polymorphism and gastric cancer risk and its development, prognosis, and survival are still being debated. This meta-analysis was performed to assess these relationships. The association reports were identified from PubMed, Embase, Cochrane Library, and CBM-disc (China Biological Medicine Database), and eligible studies were included and calculated using the meta-analysis method. VEGF+936C/T, VEGF+405 G>C, VEGF-460 T>C, VEGF-1498 T>C, and VEGF-2578 C>A gene polymorphisms were found to be unassociated with gastric cancer risk for the overall population in this meta-analysis, whereas the VEGF-634 G>C GG genotype was associated with gastric cancer risk in the overall population. Furthermore, VEGF-634 G>C C allele and the GG genotype were associated with gastric cancer risk in Caucasians, and VEGF+1612G/A gene polymorphism was associated with gastric cancer risk for the Asian population. VEGF+936C/T gene polymorphism was not associated with the stage of cancer, lymph node metastasis, Lauren classification, or survival of gastric cancer. However, VEGF+936C/T T allele and TT genotype were associated with the tumor size of gastric cancer. In conclusion, the VEGF-634 G>C GG genotype was associated with gastric cancer risk in the overall population with the VEGF-634 G>C C allele and GG genotype being associated with risk in Caucasians and VEGF+1612G/A in the Asian population.

Abstract
AIM: To evaluate the association between VEGF-634G>C gene polymorphism with premalignant gastric lesions as well as the level of VEGF. METHODS: This cross-sectional study included patients with H. pylori gastritis at Haji Adam Malik General Hospital, Permata Bunda General Hospital, and Universitas Sumatera Utara Hospital, Medan, Indonesia. Detection of H. pylori infection was made using positive results of 14C-UBT, rapid urease test, and/or immunohistochemistry. Gastric premalignant lesion diagnosis was made when one or more of the following were present: chronic atrophic gastritis, intestinal metaplasia, or dysplasia. Real-time polymerase chain reaction (RT-PCR) was used to examine VEGF-634G>C gene polymorphism. Additionally, serum samples of patients with H. pylori gastritis were obtained to determine the level of circulating VEGF. Data were analysed using SPSS version 22. RESULTS: A total number of 87 patients with H. pylori gastritis were included in this study. Of all participants, 26 patients (29.9%) showed gastric premalignancy. There was a significant association between GG+GC genotype of VEGF-634G>C and gastric premalignant lesions (P = 0.003; OR (CI 95%) = 6.07 (1.88-41.71)). VEGF-634 G>C polymorphism also showed an association with VEGF serum levels (P = 0.005). Patients with the GG+GC genotype would be at risk of 3.16 times to have high VEGF levels compared to CC genotypes. CONCLUSION: VEGF-634G>C polymorphism, in particular, GG+GC genotype was associated with an increased risk of gastric premalignant transformation as well as having high VEGF levels in patients with H.pylori gastritis.

Abstract
The association between vascular endothelial growth factor (VEGF) +936 C/T gene polymorphisms and gastric cancer risk is still controversial and ambiguous. The objective of our study was to investigate this association. The Medline and Embase databases were searched by two investigators. Crude odds ratios (OR) and 95% confidence intervals (CI) were used to test the association between VEGF +936 C/T polymorphisms and gastric cancer risk. Our meta-analysis comprised seven case-control studies, which included 1,893 gastric cancer cases and 2,245 controls. The combined results showed that there was no relationship between VEGF +936 C/T gene polymorphisms and gastric cancer risk (cc: OR 0.97, 95% CI 0.85, 1.11; CT: OR 1.01, 95% CI 0.88, 1.16; TT: OR 1.10, 95% CI 0.79, 1.55). Subgroup analysis by ethnicity and stage, location, and Lauren classification of gastric cancer did not change the results. This meta-analysis suggests that there is no association between VEGF +936 C/T polymorphisms and gastric cancer risk. Further studies should pay attention to other potentially functional SNPs.

Abstract
BACKGROUND Gastric cancer is worldwide the third major cause of cancer related death. Risk factors for gastric cancer includes Helicobacter pylori infection, gastric ulcer, less hygienic condition, use of tobacco, alcohol consumption, use of salted, smoked food, genetic alterations etc. In order to identify the risk factors associated with gastric cancer in South Indian population a case-control study involving 200 proven gastric cancer cases and 400 controls was conducted. METHODS A structured questionnaire was used to interview all the subjects who participated in our study. Genotyping assay was performed using Taqman allelic discrimination assay for 5 Single Nucleotide Polymorphisms (SNPs)-TGFβ C-509T, TGFβ T869C, XRCC1 Arg194Trp, IkBα C642T and IL4C-590T. RESULTS Odds Ratios (ORs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression. Statistical analysis on socio-economic factors, lifestyle factors had showed that subjects from low socio economic status, use of tobacco and consumption of non-vegetarian food had increased risk of developing gastric cancer. Multi-factorial analysis for the SNPs adjusting for the risk factors obtained in this study showed that TGFΒ C-509T TT genotypes had four fold increased risk of gastric cancer (OR = 4.11, CI = 1.02-16.56) and TGFβ T869C CC genotype had a decreased risk of gastric cancer (OR = 0.21, CI = 0.05-0.85). CONCLUSION Economic status, tobacco use and food habits play a significant role in gastric cancer development. TT genotype for TGFβ C-509T had an increased risk and CC genotype for TGFβ T869C had a decreased risk of gastric cancer in south Indian population after adjusting for socio-economic factors and lifestyle factors.

Abstract
The aim of the present study was to investigate whether genetic variants in the vascular endothelial growth factor A gene (VEGFA) were risk factors for papillary thyroid carcinoma (PTC) or nodular goiter (NG) in Han Chinese. A total of 2,319 subjects (861 PTC patients, 562 NG patients, and 896 healthy controls) were included. Five tag single nucleotide polymorphisms (tagSNPs: rs3024997, rs3025040, rs833070, rs25648, and rs10434) in VEGFA were genotyped. SNP rs3025040 T allele was associated with a decreased risk of NG (P<0.05). SNP rs3024997 was associated with an increased risk of PTC (P<0.05) and NG (P<0.001) when an over-dominant model (AA+GG vs. AG) was considered. PTC patients carry the less frequent TT genotype (compared to the CC genotype) (P <0.05) of SNP rs3025040. Likewise, NG patients have the less frequent TC genotype compared to the CC (P <0.05). No significant association of SNPs rs833070, rs25648, and rs10434 with PTC or NG was observed. Haplotypes AT (rs3024997 and rs3025040) and GTA (rs10434, rs3025040, and rs3024997) showed a lower risk for NG (P <0.01 and P <0.05, respectively), while haplotypes GTT (rs833070, rs3025040, and rs3024997) and GGGT (rs833070, rs10434, rs3024997, and rs3025040) predicted the risk of progression to NG (both P <0.05). Haplotype AGAC (rs833070, rs10434, rs3024997, and rs3025040) conferred protection for PTC (P <0.05). In summary, this study indicated for the first time that SNPs rs3024997 and rs3025040 in VEGFA were significantly associated with PTC and/or NG. Haplotypes of the VEGFA may influence the risk of PTC and NG.

Abstract
This study was undertaken to detect the incidence of variations in exon 5 of GSTP1, a member of the glutathione-S-transferase family, in gastric cancer in relation to histological parameters. The study included 216 gastric cancers and 300 benign gastric diseases as controls. DNA was extracted from paraffin-embedded tissues and polymerase chain reaction-restriction fragment length polymorphism analysis was performed to examine the GSTP1 Ile105Val gene polymorphism in the study participants. A positive association between GSTP1 polymorphism and gastric cancer was observed in subjects carrying at least one G allele (AG and GG); the adjusted odds ratio (OR) for GSTP1 AA versus AG+GG was 1.416 (95% confidence interval [CI] 1.007 to 1.989, after controlling for age and gender). Patients over 50 years old more frequently carried the AG+GG genotype than those aged less than 50 (P=0.011) with adjusted OR (95% CI) of 2.758 (1.227-6.201). Compared with the well-differentiated group, the incidence of the GSTP1 AA genotype was decreased in the moderately [P=0.026; OR (95% CI)=3.559 (1.072-11.813)] and poorly [P=0.003; OR (95% CI)=6.015 (1.679-21.549)] differentiated groups. The incidence of the GSTP1 AA genotype in intestinal type was higher than that in diffuse type (adjusted P=0.014; OR [95% CI]=2.210 [1.160-4.210]). All results indicated that the GSTP1 Ile105Val variant was closely associated with an increased risk of gastric cancer, and was significantly associated with patient age, tissue differentiation degree, and Lauren classification but not with gender, gross classification, tumor size (diameter), infiltration depth, and lymph node involvement.

Abstract
BACKGROUND The gene for the vascular endothelial growth factor (VEGF), which promotes angiogenesis and permeability, is polymorphic. The aim of the present study was to evaluate the relationship between +936C>T and +404C>G polymorphism of VEGF with risk of esophageal cancer in the Kashmiri population in India. MATERIALS AND METHODS 150 esophageal cancer patients and 150 unrelated healthy controls were genotyped for two VGEF SNPs (+405C/G, and +936C/T) using DNA extracted from prospectively collected blood samples by the PCR-RFLP method. RESULTS For the VEGF +936C>T polymorphism a significant association of CT and combined CT+TT genotypes was observed with increased risk of esophageal cancer (p=0.021; 0.024). For the +405C>G polymorphism we observed significantly increased frequency of GG genotype in cases as compared to controls and also the +405 GG Genotype was observed to have a two fold risk(OR=2.7356; 95%CI=1.1409- 6.5593; p=0.020). The combined genotypes of GG-CC and GG-CT of +405C>G and +936C>T were found to be significantly associated with increased risk of esophageal cancer (p=0.0376; 0.0099). CONCLUSIONS From the results of the present study a significant association of +936C>T and +405C>G polymorphisms with increased esophageal cancer risk exists in the Kashmiri population.

Abstract
A glioma is the most common type of brain tumor that accounts for nearly 80 % of brain cancers. Vascular endothelial growth factor (VEGF) and its receptor, the kinase insert domain receptor (KDR), are involved in the angiogenesis of cancers. In this study, we investigate whether the polymorphisms of VEGF and KDR are associated with a glioma risk. Blood samples were collected from 477 glioma patients and 477 healthy controls. Five tag-single nucleotide polymorphisms (SNPs) of KDR were obtained from the HapMap database, and eight tag-SNPs of VEGF were selected based on previous studies. After extraction of genomic DNAs by a Qiagen DNA blood kit, the SNPs of VEGF and KDR were genotyped with a Sequenom MassArray iPLEX platform and further analyzed with matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. The odds ratios and their 95% confidence interval (95% CI) were used to assess the association between VEGF, KDR polymorphisms, and glioma risks with the aid of SPSS 13.0 software. The haplotype analysis demonstrated that two SNPs of VEGF [rs3025039 (C>T), rs2010963 (G>C)] could elevate the susceptibility to a glioma in the homozygous model [odds ratio (OR) = 3.13 (95% confidence interval (CI) 1.30-7.49, P = 0.007) and OR = 1.58 (95% CI 1.07-2.34, P = 0.022), respectively], dominant model [OR = 1.38 (95% CI 1.04-1.84, P = 0.025) and OR = 1.32 (95% CI 1.01-1.72, P = 0.043), respectively], and allelic model [OR = 1.43 (95% CI 1.11-1.84, P = 0.005) and OR = 1.24 (95% CI 1.04-1.50, P = 0.019), respectively]. Furthermore, three SNPs of KDR [rs7667298 (A>G), rs2305948 (C>T), rs1870377 (T>A)] were also assumed to be associated with an increased risk of a glioma in the homozygous [OR = 1.93 (95% CI 1.30-2.86, P = 0.001), OR = 2.56 (95% CI 1.28-5.11, P = 0.006), and OR = 1.52 (95% CI 1.00-2.31, P = 0.049), respectively], dominant [OR = 1.52 (95% CI 1.16-1.98, P = 0.002), OR = 1.41 (95% CI 1.05-1.87, P = 0.020), and OR = 1.48 (95% CI 1.13-1.93, P = 0.004), respectively], and allele models [OR = 1.39 (95% CI 1.15-1.67, P = 0.001), OR = 1.47 (95% CI 1.14-1.89, P = 0.002), and OR = 1.27 (95% CI 1.05-1.52, P = 0.013), respectively]. The genetic polymorphisms of VEGF [rs3025039 (C>T), rs2010963 (G>C)] and KDR [rs7667298 (A>G), rs2305948 (C>T), rs1870377 (T>A)] increased glioma susceptibility in a Chinese population, suggesting the possibility of VEGF and KDR as genetic markers for glioma. Additional functional and association studies with different ethnic groups included are needed to further confirm our results.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF), an endothelial cell specific mitogen, has been implicated as a critical factor influencing tumor related angiogenesis. The aim of present study was to evaluate the relationship between VEGF +936C>T and +405C>G polymorphisms of VEGF with risk of breast cancer in Punjab, India. MATERIALS AND METHODS We screened DNA samples of 192 sporadic breast cancer patients and 192 unrelated healthy, gender and age matched control individuals for VEGF +936C>T and +405C>G polymorphisms using the PCR-RFLP method. RESULTS For the VEGF +405C>G polymorphism, we observed significantly increased frequency of GG genotype in cases as compared to controls and strong association of +405GG genotype was observed with three fold risk for breast cancer (OR=3.07; 95%CI 1.41-6.65; p=0.003). For the +936C>T polymorphism, significant associations of CT and combined CT+TT genotypes were observed with elevated risk of breast cancer (p=0.021; 0.023). The combined genotype combinations of GG-CC and GG- CT of +405C>G and +936C>T polymorphisms were found to be significantly associated with increased risk of breast cancer (p=0.04; 0.0064). CONCLUSIONS The findings of the present study indicated significant associations of VEGF +936C>T and +405C>G polymorphisms with increased breast cancer risk in patients from Punjab, North India.

Abstract
BACKGROUND Mechanisms involved in wound healing play some role in carcinogenesis in multiple organs, likely by creating a chronic inflammatory milieu. This study sought to assess the role of genetic markers in selected inflammation-related genes involved in wound healing (interleukin (IL)-1a, IL-1b, IL-1 Receptor type I (IL-1Ra), IL-1 Receptor type II (IL-1Rb), tumour necrosis factor (TNF)-α, tumour necrosis factor receptor superfamily member (TNFRSF)1A, nuclear factor kappa beta (NF-kB)1, NF-kB2, inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, hypoxia induced factor (HIF)-1α, vascular endothelial growth factor (VEGF)A and P-53) in risk to oesophageal squamous cell carcinoma (OSCC). METHODS We genotyped 125 tag single nucleotide polymorphism (SNP)s in 410 cases and 377 age and sex matched disease-free individuals from Nutritional Intervention Trial (NIT) cohort, and 546 cases and 556 controls individually matched for age, sex and neighbourhood from Shanxi case-control study, both conducted in high-risk areas of north-central China (1985-2007). Cox proportional-hazard models and conditional logistic regression models were used for SNPs analyses for NIT and Shanxi, respectively. Fisher's inverse test statistics were used to obtain gene-level significance. RESULTS Multiple SNPs were significantly associated with OSCC in both studies, however, none retained their significance after a conservative Bonferroni adjustment. Empiric p-values for tag SNPs in VEGFA in NIT were highly concentrated in the lower tail of the distribution, suggesting this gene may be influencing risk. Permutation tests confirmed the significance of this pattern. At the gene level, VEGFA yielded an empiric significance (P=0.027) in NIT. We also observed some evidence for interaction between environmental factors and some VEGFA tag SNPs. CONCLUSION Our finding adds further evidence for a potential role for markers in the VEGFA gene in the development and progression of early precancerous lesions of oesophagus.

Abstract
Vascular endothelial growth factor (VEGF) is a special heparin-binding growth factor, and can significantly stimulate vasculogenesis and angiogenesis in both cancer and healthy tissues. There have been many studies confirming that the single nucleotide polymorphisms (SNP) of VEGF have a close relationship with the occurrence, development, and prognosis of diseases. According to statistics, the human VEGF gene has at least 30 SNP loci, among which VEGF -634C/G, -936C/T and -2578C/A mutations have been proved to regulate the VEGF plasma levels. Here we review the recent advances in understanding the association between VEGF -634G/C polymorphism and diseases.

Abstract
INTRODUCTION The expression of plasminogen activator inhibitor type 1 (PAI-1), vascular endothelial growth factor (VEGF), and transforming growth factor β1 (TGF-β1) participates in the angiogenesis of several cancer types. The goal of this study was to investigate polymorphisms in genes related to angiogenesis (PAI-1-675 4G/5G, VEGF C936T, and TGF-β1 G-800A) to evaluate the risk for developing uterine cervical cancer (UCC). METHODS In a case-control study, 100 healthy subjects and 100 patients with UCC from Mexico were included. We determined the genetic profile of the polymorphic markers, which were evaluated by polymerase chain reaction using a sequence-specific primer. RESULTS There was no statistical difference in the allele distribution from the intergroup comparisons of PAI-1 675 4G/5G and VEGF C936T data; however, a significant difference was observed within TGF-β1 G-800A. The linkage disequilibrium analysis revealed that PAI-1 -675 4G and TGF-β1 -800A pair-haplotype was in strong linkage disequilibrium with a significantly increased risk (odds ratio, 3.44; 95% confidence interval, 1.66-7.25) to UCC. CONCLUSIONS The polymorphisms in the genes related to angiogenesis -675 4G/5G PAI-1 and G-800A TGF-β1, segregated solely or combined, might contribute to the increased susceptibility to UCC in a Mexican population.

Abstract
Vascular endothelial growth factor (VEGF) polymorphisms, specifically +405G/C (rs2010963), reportedly influence the risk for various digestive cancers. However, the consequences of these polymorphisms remain controversial and ambiguous. Therefore, we performed a meta-analysis of 11 studies with VEGF +405G/C genotyping on 2,862 patients and 3,028 controls using the random effects model. We obtained a pooled odds ratio (OR) of 1.04 (95% confidence interval (CI) = 0.86-1.26) for the recessive genetic model, 1.07 (95% CI = 0.81-1.42) for the dominant genetic model, 1.09 (95% CI = 0.81-1.47) for the homozygote comparison, and 1.03 (95% CI = 0.83-1.27) for the heterozygote comparison. In the subgroup analysis of the recessive model, the OR was 1.20 (95% CI = 1.02-1.40) in colorectal cancer. These results show that VEGF +405G/C polymorphisms are unlikely to be a major determinant of susceptibility to digestive cancer. Furthermore, the subgroup analysis of recessive model indicates that VEGF +405G/C polymorphisms increase the risk for colorectal cancer.

Abstract
CD133 is one of the most common stem cell markers, and functional single nucleotide polymorphisms (SNPs) of CD133 may modulate its gene functions and thus cancer risk and patient survival. We hypothesized that potentially functional CD133 SNPs are associated with gastric cancer (GC) risk and survival. To test this hypothesis, we conducted a case-control study of 371 GC patients and 313 cancer-free controls frequency-matched by age, sex, and ethnicity. We genotyped four selected, potentially functional CD133 SNPs (rs2240688A>C, rs7686732C>G, rs10022537T>A, and rs3130C>T) and used logistic regression analysis for associations of these SNPs with GC risk and Cox hazards regression analysis for survival. We found that compared with the miRNA binding site rs2240688 AA genotype, AC + CC genotypes were associated with significantly increased GC risk (adjusted OR = 1.52, 95% CI = 1.09-2.13); for another miRNA binding site rs3130C>T SNP, the TT genotype was associated with significantly reduced GC risk (adjusted OR = 0.68, 95% CI = 0.48-0.97), compared with CC + CT genotypes. In all patients, the risk rs3130 TT variant genotype was significantly associated with overall survival (OS) (adjusted P(trend) = 0.016 and 0.007 under additive and recessive models, respectively). These findings suggest that these two CD133 miRNA binding site variants, rs2240688 and rs3130, may be potential biomarkers for genetic susceptibility to GC and possible predictors for survival in GC patients but require further validation by larger studies.

Abstract
To derive a more precise estimation of the relationship between TGF-β1 polymorphisms and gastric cancer (GC) risk, we conducted a meta-analysis of all available case-control studies relating the C-509 T, T869C, and G 915C polymorphisms of the TGF-β1 gene to the risk of developing GC. The effect summary odds ratio (OR) and 95% confidence intervals (CIs) were obtained. Funnel plots and Egger's test were used to estimate publication bias. Finally, 11 studies were included in the final meta-analysis. With respect to C-509 T polymorphism, it was found that significantly increased GC risk was associated with the TT genotype in the recessive genetic model in overall analysis (TT vs. CC + CT: OR = 1.23, 95% CI 1.09-1.38, P(heterogeneity) = 0.13) and in Asian population (TT vs. CC + CT: OR = 1.24, 95% CI 1.10-1.39, P(heterogeneity) = 0.18). With respect to T869C and G915C polymorphisms, no significant association with GC risk was demonstrated in overall analysis and subgroup analyses according to ethnicity for all genetic models. This meta-analysis suggested that the T allele of TGF-β1 509C/T polymorphism is probably the susceptibility factor for GC.

Abstract
OBJECTIVE To investigate the association between three single nucleotide polymorphisms (SNPs) of the vascular endothelial growth factor (VEGF) gene and the risk of glioma in a Han Chinese population. METHODS This hospital-based case-control study used polymerase chain reaction-restriction fragment length polymorphism analysis to detect three SNPs (-634 G/C, +936 C/T and +1612 G/A) of the VEGF gene in patients with glioma compared with healthy control subjects. RESULTS The study investigated 880 patients with gliomas and 880 age- and sex-matched healthy control subjects. Patients with gliomas had a significantly higher frequency of the -634 CC genotype (odds ratio [OR] 1.35, 95% confidence interval [CI] 1.05, 1.75) and the +936 TT (OR 1.73, 95% CI 1.20, 2.48) genotype compared with the control subjects. Patients with glioblastomas had a significantly higher frequency of the -634 CC and +936 TT genotypes. Patients with grade IV gliomas had a significantly higher frequency of the -634 CC and +936 TT genotypes. The +1612 G/A polymorphisms were not associated with glioma risk. CONCLUSION The VEGF - 634 CC and +936 TT genotypes were associated with a higher risk of glioma in a Han Chinese population.

Abstract
Vascular Endothelial Growth Factor A (VEGF-A) is a potent secreted mitogen crucial for physiological and pathological angiogenesis. Post-transcriptional regulation of VEGF-A occurs at multiple levels. Firstly, alternative splicing gives rise to different transcript variants encoding diverse isoforms that exhibit distinct biological properties with regard to receptor binding and extra-cellular localization. Secondly, VEGF-A mRNA stability is regulated by effectors such as hypoxia or growth factors through the binding of stabilizing and destabilizing proteins at AU-rich elements located in the 3′-untranslated region. Thirdly, translation of VEGF-A mRNA is a controlled process involving alternative initiation codons, internal ribosome entry sites (IRESs), an upstream open reading frame (uORF), miRNA targeting and a riboswitch in the 3′ untranslated region. These different levels of regulation cooperate for the crucial fine-tuning of the expression of VEGF-A variants. This review will be focused on our current knowledge of the complex post-transcriptional regulatory switches that modulate the cellular VEGF-A level, a paradigmatic model of post-transcriptional regulation.

Abstract
AIM To investigate the association of transforming growth factor-beta 1 (TGF-β1) C-509T polymorphism and susceptibility to cancer by means of meta-analysis. METHODS An extensive search was performed to identify eligible case-control studies investigating such a link. The strength of the association between TGF-β1 C-509T polymorphism and cancer risk was assessed by pooled odds ratios (ORs) and 95%confidence intervals (95%CIs) in fixed or random effects models. RESULTS 55 published case-control studies with a total number of 21,639 cases and 28,460 controls were included. Overall, there was no association between TGF-β1 C-509T and cancer risk in all genetic comparison models (TT vs. CC: OR=1.01, 95%CI=0.89-1.15; T vs. C: OR=1.01, 95%CI=0.94-1.07). However, a stratified analysis by cancer type indicated -509 T allele was significantly associated with decreased risk of colorectal cancer (CRC) (TT vs. CT/CC: OR=0.85, 95%CI=0.76-0.95), especially for Caucasians (TT vs. CT/CC: OR=0.83, 95%CI=0.71-0.98) and for population-based studies (TT vs. CT/CC: OR=0.78, 95%CI=0.68- 0.89). CONCLUSION This meta-analysis suggested that TGF-β1 C-509T polymorphism might contribute to a decreased risk on colorectal cancer susceptibility, especially for Caucasians.

Abstract
Background TNFAIP2 is a crucial gene involved in apoptosis. Single nucleotide polymorphisms (SNPs) in its miRNA binding sites could modulate functions of the miRNA-target genes and thus risk of cancers. In this study, we investigated associations between potentially functional SNPs in the miRNA binding sites of the 3′UTR of TNFAIP2 and gastric cancer risk in a US population. Methods We conducted a case-control study of 301 gastric cancer patients and 313 cancer-free controls frequency-matched by age, sex and ethnicity. We genotyped four selected TNFAIP2 SNPs (rs8126 T>C, rs710100 G>A, rs1052912 G>A and rs1052823 G>T) and used the logistic regression analysis to assess associations of these SNPs with cancer risk. Results The rs8126 CC genotype was associated with a significantly elevated risk of gastric cancer (adjusted OR = 2.00, 95% CI = 1.09–3.64 and P = 0.024), compared with the combined rs8126 TT+TC genotypes, particularly in current drinkers. However, none of other TNFAIP2 SNPs was associated with risk of gastric cancer. Conclusions Our data suggested that the TNFAIP2 miRNA binding site rs8126 T>C SNP may be a marker for susceptibility to gastric cancer, and this finding requires further validation by larger studies.

Abstract
The association between transforming growth factor β1 (TGF-β1)-509 C>T and risk of digestive tract cancer (DTC) remained uncertain as previous studies reported conflicting results. The aim of this study was to assess the association by using a meta-analysis. The databases of MEDLINE, EMBASE and WANGFANG (Chinese database) were retrieved, and latest update was on 2nd February, 2012. Pooled odds ratio and 95% confidence interval (OR and 95% CI) were calculated by using a fixed- or random-effect model. Ultimately, twenty nine case-control studies with 8664 cases and 12,532 controls were included in this meta-analysis. Overall, there was no association between TGF-β1-509 C>T and risk of DTC in all genetic comparison models (OR and 95% CI: 0.96 and 0.81-1.15 for TT vs. CC, 0.98 and 0.91-1.05 for T carriers vs. C carriers). When subgroup analyses were conducted according to ethnicity, types of cancer and sample size, T allele was significantly associated with decreased risk of DTC for Caucasians and for large sample-sized studies, and was associated with decreased risk of colorectal cancer (OR and 95% CI for TT vs. CC: 0.82 and 0.70-0.97 for Caucasians, 0.80 and 0.68-0.98 for large sample-sized studies, 0.78 and 0.62-0.97 for colorectal cancer). This study indicated that TGF-β1-509 C>T polymorphism was probably associated with risk of DTC, especially for Caucasians. Because of modest limitation, our findings should be confirmed by future studies.

Abstract
The association of VEGF+405G/C (where VEGF is vascular endothelial growth factor) polymorphism and malignancy susceptibility attracts considerable attention because VEGF is one of the most potent angiogenic factors and plays a critical role in the onset and development of malignancy. However, the published findings remain inconclusive. In order to derive a more precise assessment of the association, we performed a meta-analysis including 30 published case-control studies from PubMed, Embase, and Ovid databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association. In the pooled analyses, no significant association was found between VEGF+405G/C polymorphism and malignancy susceptibility in different genetic models (G-allele vs. C-allele: OR = 1.00, 95% CI: 0.93–1.07; CC vs. GG: OR = 1.01, 95% CI: 0.88–1.15; GC+CC vs. GG: OR = 1.00, 95% CI: 0.91–1.10; CC vs. GC+GG: OR = 1.01, 95% CI: 0.90–1.13). When stratified by ethnicity, a weak association between this polymorphism and malignancy susceptibility was found in African under allelic frequency comparison (OR = 0.65, 95% CI: 0.43–0.98) and dominant genetic model comparison (OR = 1.95, 95% CI: 1.09–3.50). In summary, although our meta-analysis indicated a weak association of VEGF+405G/C polymorphism with malignancy susceptibility in African, no persuasive evidence of association between the polymorphism and malignancy susceptibility was detected in the pooled analyses. Therefore, more studies with larger scale of participants, especially Africans, are required to further evaluate gene-environment interaction on this polymorphism and malignancy susceptibility.

Abstract
Vascular endothelial growth factor A (VEGF-A) is a key mediator in the neovascularization of cancers. We have found that VEGF-A was expressed at significantly higher levels in high-grade transitional cell carcinoma (TCC) cells than low-grade TCC cells in our previous study. In the present study, promoter methylation pattern was assessed and quantified by bisulfite genomic sequencing (BGS) and specific VEGF-A CpG sites in low-grade, but not in high-grade, TCC cells were observed. Reporter assays indicated that hypermethylation of nine CpG sites can inhibit the transcriptional activity of the VEGF-A gene. Subsequent chromatin immunoprecipitation (ChIP) assay revealed down-regulation of transcription activity of VEGF-A with increasing binding of methyl-CpG-binding protein 2 (MBD2) and trimethyl-histone H3 (Lys9) proteins to these CpG sites in low-grade TCC cells during hypermethylation. Furthermore, treatment of low-grade TCC cells with DNA methyltransferase inhibitor and histone deacetylase inhibitor can restore the expression of VEGF-A and promote the invasive ability of low-grade TCC cells. Hypermethylation with lower expression levels of VEGF-A in low-grade TCC tumors than high-grade TCC tumors was also confirmed in clinical specimens by reverse transcriptase-PCR and pyrosequencing analyses. Our findings are the first results indicating that VEGF-A expression is suppressed in low-grade TCC tumors by promoter hypermethylation. This offers a new perspective on the role of VEGF-A in TCC tumor behavior.

Abstract
BACKGROUNDS/AIMS Metastatic tumour antigen 1 (MTA1) promotes angiogenesis by stabilizing hypoxia-inducible factor-1α (HIF-1α), which is closely associated with frequent postoperative recurrence and poor survival in patients with HCC. In this study, we determined single nucleotide polymorphisms (SNPs) in angiogenesis-related genes that are associated with MTA1 overexpression in HCC tissues. METHODS A total of 376 patients with HCC who had received curative surgical resection or liver transplantation were enrolled (312/21/43; HBV/HCV/NBNC). MTA1 expression was determined via immunohistochemistry. Thirty-three common SNPs sites (frequency ≥5%) in the angiogenic protein gene that are closely connected to one another were selected, including MTA1, VEGF, HIF-1α, FGF-2, and IGF-II. RESULTS Expression of MTA1 was detected in 120 HCC tissues (31%). An A allele at position IVS4-81G/A of the MTA1 gene (P = 0.016) and the TT genotype at position +12916C of the VEGF gene (P = 0.023) were significantly associated with MTA1 overexpression. However, the TT genotype at position -13021C (P = 0.011) and the haplotypes CT-CT (-11228C; -13021C) of the IGF-II gene (P(cor) = 0.033) were more common in patients with MTA1-negative HCC. Using multivariate analysis, the A allele at IVS4-81G/A in MTA1 gene (P = 0.015) and a T allele (TT+CT genotype) at -13021C in IGF-II (P = 0.002) were independent risk factors in HCC recurrence after curative surgical resection. CONCLUSIONS The genetic polymorphisms IVS4-81G/A in MTA1 and +12916C in VEGF genes were correlated with MTA1 overexpression. The SNPs in MTA1 and IGF-II genes may be important risk factors for the recurrence of HCC.

Abstract
BACKGROUND Gastric cancer is one of the leading causes of cancer death. With greater understanding of the molecular basis of carcinogenesis, targeted agents have led to a modest improvement in the outcome of advanced gastric cancer (AGC) patients. METHODS AND RESULTS We conducted an overview of the published evidence regarding the use of targeted therapy in AGC patients. Thus far, the human epidermal growth factor receptor (HER) pathway, angiogenic pathway, and phosphatidylinositol-3-kinase (PI3K)-Akt-mammalian target of rapamycin pathway have emerged as potential avenues for targeted therapy in AGC patients. The promising efficacy results of the Trastuzumab for Gastric Cancer trial led to the approved use of trastuzumab-based therapy as first-line treatment for patients with HER-2+ AGC. On the other hand, the Avastin® in Gastric Cancer trial evaluating bevacizumab in combination with chemotherapy did not meet its primary endpoint of a longer overall survival duration despite a significantly higher response rate and longer progression-free survival time in patients in the bevacizumab arm. Phase III data are awaited for other targeted agents, including cetuximab, panitumumab, lapatinib, and everolimus. CONCLUSION Recent progress in targeted therapy development for AGC has been modest. Further improvement in the outcome of AGC patients will depend on the identification of biomarkers in different patient populations to facilitate the understanding of gastric carcinogenesis, combining different targeted agents with chemotherapy, and unraveling new molecular targets for therapeutic intervention.

Abstract
The aim of this study was to determine whether the vascular endothelial growth factor (VEGF) +936C/T polymorphism confers susceptibility to gastric cancer (GC) by conducting a meta-analysis. Publications addressing the association between the VEGF +936C/T polymorphism and GC risk were selected from the Pubmed, Embase and CBM databases. Data were extracted from the studies by two independent reviewers. The meta-analysis was performed using RevMan 5.0.25 and STATA 9.2 software. From these data, the odds ratio (OR) with 95% confidence interval (CI) was calculated. Finally, 8 case-control studies were retrieved reporting a total of 2,131 gastrointestinal cancer patients and 2,670 controls. Meta-analysis results showed that there was no significant association between the VEGF +936C/T polymorphism and GC risk in all comparisons of the T allele vs. C allele (OR=1.08, 95% CI 0.90-1.30, P=0.42), CT+TT vs. CC (OR=1.08, 95% CI 0.87-1.34, P=0.49), TT vs. CC+CT (OR=1.14, 95% CI 0.85-1.53, P=0.37), TT vs. CC (OR=1.18, 95% CI 0.87-1.59, P=0.28) and TT vs. CT (OR=1.11, 95% CI 0.79-1.56, P=0.56). This meta-analysis confirms that there is a lack of association between the VEGF +936C/T polymorphism and GC risk.

Abstract
The transforming growth factor-β (TGFβ) pathway plays an important role in various types of human cancer. However, the role of TGFB1 -509C/T and TGFBR2 -875A/G polymorphisms in gastric cancer is controversial. We aimed to investigate the associations between these polymorphisms and gastric cancer susceptibility, clinicopathological parameters and survival. A case-control study was conducted in 1,010 gastric cancer patients and 1,500 healthy controls. Genotypes were determined by PCR-restriction fragment length polymorphism and DNA sequencing. Compared with the TT genotype, the TGFB1 -509 C allele (CT/CC) was significantly associated with a reduced risk of gastric cancer (OR, 0.71; 95% CI, 0.58-0.87; p=0.001) and certain subtypes of gastric cancer including intestinal type (OR, 0.70; 95% CI, 0.57-0.87; p=0.001), poorly differentiated (OR, 0.67; 95% CI, 0.54-0.85; p=0.001) and stage TNM III+IV (OR, 0.73; 95% CI, 0.58-0.92; p=0.008). Compared with the TGFBR2 -875 GG genotype, carriers of the A allele (AA/AG) had a significantly decreased gastric cancer risk (OR, 0.58; 95% CI, 0.62-0.91; P<0.001). A combination of the TGFB1 -509 C and TGFBR2 -875 A alleles was associated with a further decreased risk of gastric cancer (OR, 0.42; 95% CI, 0.32-0.57, p<0.001). No significant correlation was observed between polymorphisms and survival of gastric cancer patients. Our results suggest that both the TGFB1 -509 and TGFBR2 -875 polymorphisms contribute to a decreased gastric cancer risk. The TGFB1 -509 polymorphism affects certain subtypes of gastric cancer according to clinicopathological parameters. A combination of the TGFB1 -509 C and TGFBR2 -875 A alleles conferred a further decreased gastric cancer risk. These findings provide clues to the biological mechanisms that underline tumor heterogeneity.

Abstract
PURPOSE The association between polymorphism of vascular endothelial growth factor (VEGF)-634 G>C and malignancy risk has been widely studied, and no conclusive result was available up to now. METHODS Twenty-three case-control studies with 21,917 individuals were included in this meta-analysis through searching the databases of Medline, Embase, and CNKI (up to October 1st, 2010). The odds ratio (OR) and 95% confidence interval (95%CI) were used to investigate the strength of the association. RESULTS Overall, the pooled analysis showed that there was no association between VEGF-634 G>C and risk of malignancy, and the ORs (95%CIs) were 0.98 (0.85-1.12) for GG versus CC, 1.03 (0.90-1.17) for GC versus CC, 1.00 (0.89-1.13) for G carrier versus CC, and 1.08 (0.94-1.23) for C carrier versus GG. Subgroup analyses according to ethnicity, source of control, type of cancer, and sample size were also performed, and results indicated that VEGF-634 G>C was not associated with risk of malignancy for neither Asians [1.06 (0.81-1.38) for GG vs. CC and 1.08 (0.84-1.39) for GC vs. CC] nor Caucasians [0.93 (0.83-1.05) for GG vs. CC and 0.98 (0.87-1.10) for GC vs. CC]. It was also not associated with risk of breast cancer [0.95 (0.81-1.12) for GG vs. CC], gastric cancer [0.93 (0.47-1.84) for GG vs. CC], and colorectal cancer [1.17 (0.93-1.47) for GG vs. CC]. CONCLUSIONS This meta-analysis suggests that VEGF-634 G>C may be not associated with risk of malignancy. More studies with larger sample size were needed to provide more precise evidence.

Abstract
The association between vascular endothelial growth factor (VEGF) gene polymorphisms and gastric cancer risk is still controversial and ambiguous. The objective of this study was to investigate the association between VEGF gene polymorphisms and gastric cancer risk in Chinese Han patients. We extracted the peripheral blood samples in 150 patients with gastric cancer and 150 controls. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis was performed to detect three VEGF gene polymorphisms (-634 G/C, +936 C/T, and +1612 G/A) in these patients. Patients with gastric cancer had a significantly higher frequency of 1612 AA genotype (OR=6.26, 95% CI=1.80, 21.85; P=0.004) than controls. Patients with cardia gastric cancer had a significantly lower frequency of AA (OR=0.11, 95% CI=0.01, 0.89; P=0.04) than those with noncardia gastric cancer. Patients with Lauren's diffuse-type gastric cancer had a significantly higher frequency of AA (OR=3.41, 95% CI=1.22, 9.55; P=0.02) than those with Lauren's intestinal-type gastric cancer. The -634 G/C and +936 C/T gene polymorphisms were not associated with a risk of GC and its progression. This study suggests that the VEGF +1612 G/A gene polymorphisms may be associated with gastric cancer in Chinese Han patients, and that difference in genotype distribution may be associated with the location and Lauren's classification of gastric cancer.

Abstract
Gastric cancer (GC) is an important cause of morbidity and mortality worldwide. In addition to environmental factors, genetic factors also play an important role in GC etiology, as demonstrated by the fact that only a small proportion of individuals exposed to the known environmental risk factors develop GC. Molecular studies have provided evidence that GC arises not only from the combined effects of environmental factors and susceptible genetic variants but also from the accumulation of genetic and epigenetic alterations that play crucial roles in the process of cellular immortalization and tumorigenesis. This review is intended to focus on the recently described basic aspects that play key roles in the process of gastric carcinogenesis. Genetic variation in the genes DNMT3A, PSCA, VEGF, and XRCC1 has been reported to modify the risk of developing gastric carcinoma. Several genes have been newly associated with gastric carcinogenesis, both through oncogenic activation (MYC, SEMA5A, BCL2L12, RBP2 and BUBR1) and tumor suppressor gene inactivation mechanisms (KLF6, RELN, PTCH1A, CLDN11, and SFRP5). At the level of gastric carcinoma treatment, the HER-2 tyrosine kinase receptor has been demonstrated to be a molecular target of therapy.

Abstract
Angiogenesis, the formation of new blood vessels from existing vasculature, plays an essential role in tumour growth, invasion and metastasis. Vascular endothelial growth factor (VEGF) is one of the key factors responsible for its regulation. High expression of VEGF has been observed in many cancers, and is associated with worse survival. When antiangiogenic agents are used alone they typically initially cause reduction in blood flow or vascular permeability, in many types of cancer. In some cases tumour regression occurs, mainly in renal cancer. In combination with chemotherapy, progression-free survival is often prolonged, but overall survival is not. Many tumours fail to respond initially - de novo resistance. Others develop resistance over time, with progression after a few months of treatment. The mechanisms of resistance are not well understood. The theoretical benefits of VEGF inhibitors are more likely to be realised by understanding these mechanisms and modifying therapy accordingly. This article reviews current knowledge on resistance mechanisms and the therapeutic implications.

Abstract
Helicobacter pylori (H. pylori) stimulates secretion of monocyte chemoattractant protein 1 (MCP-1) from gastric mucosa. Monocyte chemoattractant protein-1 (MCP-1) expression and macrophage infiltration are recognized in human gastric carcinoma. We have previously generated Cdx2-transgenic mice as model mice for intestinal metaplasia. Both chronic H. pylori-associated gastritis and Cdx2-transgenic mouse stomach develop intestinal metaplasia and finally gastric carcinoma. In this study we have directed our attention to MCP-1 expression in the intestinal metaplastic mucosa and the gastric carcinoma of Cdx2-transgenic mouse stomach. Quantitative real-time PCR was performed to determine MCP-1 and transforming growth factor-beta1 (TGF-beta1) mRNA expression levels and single- or double-label immunohistochemistry was used to evaluate the localization of MCP-1, TGF-beta type I receptor, and alpha-smooth muscle actin (alphaSMA). We determined that MCP-1 mRNA dramatically increased in the intestinal metaplastic mucosa and the gastric carcinoma of Cdx2-transgenic mouse stomach, compared with normal mouse stomach. Both MCP-1 and TGF-beta type I receptor were co-expressed in the alphaSMA-positive myofibroblasts of intestinal metaplastic mucosa and gastric carcinoma. Exogenous application of TGF-beta1 increased MCP-1 mRNA expression levels in the intestinal metaplastic tissue. Furthermore, TGF-beta1 was overexpressed and macrophage was strongly infiltrated in the gastric carcinoma. In conclusion, MCP-1 expression, which was stimulated by TGF-beta1, was recognized in the TGF-beta type I receptor-expressing myofibroblasts of the intestinal metaplastic mucosa and the gastric carcinoma of Cdx2-transgenic mouse stomach. The present results suggest that intestinal metaplasia and gastric carcinoma themselves induce MCP-1 expression independently of H. pylori infection.
