Abstract
BACKGROUND Angiogenesis play a critical role in the development and progression of tumors in solid tumors. Vascular endothelial growth factor (VEGF) is one of the most important endothelial cell mitogen which plays a critical role in normal physiological and tumor angiogenesis. OBJECTIVES The objective of this case-control study was to investigate the association of VEGF-2578C/A, -2549 I/D, and -460T/C promoter polymorphisms with esophageal cancer risk in North-West Indians. METHODS In this study, 200 sporadic esophageal cancer patients and 200 healthy, unrelated, age and gender matched controls were analyzed. The genomic DNA was extracted from blood samples using phenol chloroform method. Genotyping of VEGF- 2549I/D polymorphism was carried out by direct polymerase chain reaction (PCR) whereas VEGF -2578C/A and VEGF-460T/C) polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. RESULTS AA genotype (p = 0.005) and A allele (p = 0.005) VEGF -2578 C/A, II genotype (p = 0.011) and I allele (p = 0.012) of VEGF - 2549 I/D and CC genotype (p = 0.013) and C allele of VEGF-460T/C polymorphisms were significantly associated with increased risk of esophageal cancer. Stratification of data on the basis of gender showed that VEGF -2578 AA genotype (p = 0.001) and A allele (p = 0.001); VEGF -2549 II genotype (p = 0.002) and I allele (p = 0.002) and VEGF- 460CC genotype (p = 0.001) and C allele (p = 0.002) was significantly associated with increased risk of esophageal cancer in female group. Haplotype analysis revealed that A-2578 I- 2549 C- 460 haplotype was significantly associated with increased risk for esophageal cancer in total samples (p = 0.008) as well as in female group (p = 0.001). CONCLUSIONS The results of present study indicate that VEGF -2578C/A, - 2549I/D and -460T/C polymorphisms were significantly associated with increased risk of esophageal cancer in North-West Indians.

Abstract
OBJECTIVE The relationship between the clinicopathological and sociodemographics characteristics of acral melanomas diagnosed at BACKGROUND: This study aimed to investigate the frequency of VEGF gene insertion (I) / deletion (D) polymorphism (rs35569394) in patients with Polycystic Ovarian Syndrome (PCOS) and to compare with a control population to verify its association with the pathology. METHODS 206 women participated in this study, 103 with PCOS (group of patients) and 103 without the disease (control group). After extraction of genomic DNA from the samples, molecular analysis was performed by Polymerase Chain Reaction (PCR) and electrophoresis in polycrylamide. Descriptive analysis, univariate analysis and logistic regression model were used. Results were presented in odds ratio (OR) and 95% confidence interval (95% CI), considering the significance of p <0.05. RESULTS There were no statistical differences between patients and controls for allele frequencies (χ2 = 1.16, p = 0.56). The genotypic frequency distribution was in Hardy Weinberg equilibrium for the patients (χ2 = 2.42; p <0.05), but not for the control group (χ2 = 7.26; p <0.05). Regarding risk factors for the syndrome, a history of familial PCOS is more frequent among women with the syndrome. CONCLUSIONS In the present study, there is no association between VEGF gene I / D polymorphism and PCOS.

Abstract
Purpose Vascular endothelial growth factor (VEGF) is a potent inducer of micro vascular permeability thus leading to nephropathy. Insertion/deletion (I/D) polymorphism of 18 bp at - 2549 position in VEGF gene causes increased transcription leading to increased production of VEGF. Thus, we aimed to associate I/D polymorphism of the 18 bp fragment at - 2549 position of the promoter region of VEGF gene with sickle cell nephropathy (SCN). Methods This observational analytical case control study included 30 subjects each of SCN, sickle cell disease (SCD) without nephropathy and the control group. The subjects were assessed for various hematological and biochemical parameters. Further, 18 bp I/D polymorphism of VEGF gene in all three study groups was assessed by polymerase chain reaction followed by electrophoresis and compared. Result Though increased frequency of both DD genotype and D allele was found in SCN compared to SCD and control, only frequency of D allele was found to be significantly higher (p = 0.04). D allele posed marginal risk of microalbuminuria in SCD subjects compared to controls (OR = 2.11) as well as to SCD without MA subjects (OR = 1.84). Conclusion D allele in I/D polymorphism in the promoter region of VEGF gene may be associated with marginal increase in risk of susceptibility to sickle cell nephropathy.

Abstract
Endometriosis is a debilitating disorder, defined as the presence of endometrial gland and stroma outside of the uterus. It may affect angiogenesis and vascular endothelial growth factor (VEGF) is one of the angiogenic factors that plays an important role in both physiological and pathological angiogenesis. The present study aimed to evaluate the association of VEGF -2549 insertion/deletion (I/D) polymorphism with endometriosis. This case-control study enrolled 244 (100 cases and 144 controls) women who were admitted for laparoscopy or laparotomy for gynecological procedures. Genomic DNA was separated from peripheral blood leukocytes and polymerase chain reaction (PCR) amplification was performed for genotyping of the VEGF gene Insertion/Deletion (I/D) polymorphism. The frequency of the II, ID, and DD genotype was 14%, 52% and 34% in patients versus 18.8%, 47.8% and 34% in controls. The results did not provide any evidence supporting the endometriosis risk related to the VEGF polymorphism in a group of Iranian women population.

Abstract
Vascular endothelial growth factor A (VEGFA) is an important angiogenesis regulator, which plays an important role in angiogenesis and progression of tumor, including hepatocellular carcinoma (HCC). We aimed at determining whether single nucleotide polymorphisms of VEGFA gene influence the development and clinical outcomes of HCC. We analyzed four potential functional polymorphisms (936C/T, 634G/C, 1612G/A, 2578C/A) of VEGFA gene in 476 HCC patients and 526 controls using matrix-assisted laser desorption ionization time-of-flight mass spectrometry method. Serum VEGF levels were measured by enzyme-linked immunosorbent assay. The Kaplan-Meier methods with log-rank test and Cox regression models were used to compare survival of resected HCC patients according to the genotype. We found that only the VEGFA 2578C/A polymorphism was significantly associated with decreased risk of HCC (AA/AC vs. CC; adjusted OR = 0.69, 95% CI = 0.51-0.93). Furthermore, the 2578C/A polymorphism was associated with significantly decreased postoperative recurrence (AA/AC vs. CC, adjusted OR = 0.51; 95% CI, 0.29-0.88) and improved overall survival (AA/AC vs. CC, adjusted HR = 0.27, 95% CI = 0.13-0.52) of resected HCC patients. In addition, the VEGF serum levels in HCC patients were significantly higher than those in healthy controls, although no significant association between VEGFA genotype and serum levels of VEGF was observed. These results suggest that the VEGFA 2578 C/A polymorphism may play a potential role in the development and clinical outcome of HCC among Chinese Han population.

Abstract
The aim of present study was to evaluate the relationship between vascular endothelial growth factor (VEGF) -2578C/A, -2549I/D, -460T/C and -7C/T and VEGFR1 -710C/T polymorphisms with risk to breast cancer in North Indians. A total of 204 sporadic breast cancer patients and 204 controls were recruited for this case-control study. Significantly increased frequency of II genotype of -2549I/D polymorphism was observed in patients as compared to control individuals (odds ratio (OR) = 2.76, 95 % confidence interval (CI), 1.55-4.92; p = 0.0005). VEGF -2578AA genotype (OR = 2.87; 95 % CI, 1.61-5.10; p = 0.0003) and A allele (OR = 1.65, 95 % CI, 1.25-2.18; p = 0.0004) were found to be associated with increased risk for breast cancer. Individuals carrying CC genotype (OR = 2.23, 95 % CI, 1.25-3.97) and C allele (OR = 1.42, 95 % CI, 1.07-1.87) of VEGF -460T/C polymorphism were at higher risk of breast cancer. There was no significant difference in genotype and allele distribution of VEGF -7C/T and VEGFR1 -710C/T polymorphisms between cases and control individuals (p > 0.05). Linkage disequilibrium analysis showed a strong linkage between VEGF -2549I/D and -2578C/A polymorphisms (Lewontin's [Formula: see text] = 0.99; r (2) = 0.97), -2549I/D and -460T/C ([Formula: see text] = 0.94; r (2) = 0.84), and -2578C/A and -460T/C polymorphisms ([Formula: see text] = 0.93; r (2) = 0.83). In the present study, we concluded that VEGF -2549I/D, -2578C/A and -460T/C polymorphisms are associated with risk to breast cancer in Punjab, North India.

Abstract
AIMS The aim of the present study was to assess the role of the vascular endothelial growth factor (VEGF) -2549 insertion/deletion (I/D) polymorphism in susceptibility to sporadic breast cancer. METHODS DNA samples of 94 breast cancer patients and 94 unrelated healthy control individuals with matched age and gender from the same geographical region of Punjab, North West India were screened for the -2549 I/D polymorphism. Serum VEGF-C (sVEGF-C) levels of breast cancer patients and healthy controls were measured using an enzyme-linked immunosorbent assay. RESULTS The frequency of the II, ID, and DD genotype was 23.40 versus 10.64%, 48.94 versus 52.13%, and 27.66 versus 37.23%, in patients and controls, respectively. A statistically significant difference was observed for genotype distribution among the patients and controls (χ(2)=6.039, p=0.049). There was a significant increase in the I allele frequency in the patients as compared with controls (47.86 versus 36.70%, p=0.028). The sVEGF-C levels were also considerably higher in patients as compared to healthy controls (p<0.01). CONCLUSIONS The VEGF -2549 I/D polymorphism has a role in the susceptibility to breast cancer in the Amritsar region of Punjab, India.

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
Hepatocellular carcinoma (HCC) represents the most common primary malignancy of the liver with a worldwide increasing incidence. Although the risk factors for HCC are well characterized, the molecular mechanisms responsible for malignant transformation of hepatocytes are not well understood. In this study, a case-control study including 291 HCC patients and 294 healthy controls was conducted to investigate the association between HCC susceptibility and with a 4-bp insertion/deletion polymorphism (rs66465034) in the proximal promoter of CD3G. Logistic regression analysis showed that the heterozygote and the homozygote 4-bp ins/ins confer a significantly increased risk of HCC after controlling for other covariates (adjusted odds ratio [OR]=1.51, 95% confidence interval [C.I.] 1.01-2.27, p=0.040; OR=1.71, 95% C.I. 1.07-2.89, p=0.025, respectively). Carriage of the 4-bp insertion allele was associated with a greatly increased risk of developing the disease (OR=1.30, 95% C.I. 1.02-1.64, p=0.027). Moreover, hepatitis B virus (HBV) stratification analysis showed that the differences between cases and controls were more obvious in HBV-positive than in the HBV-negative population, suggesting a possible role of this polymorphism in the immune regulation during HBV infection. Further, luciferase-based transient transfection assays revealed that rs66465034 can affect promoter activity of CD3G, indicating its possible functional significance. Our data suggested that common genetic polymorphisms in CD3G may influence HCC risk in Chinese population. Considering the relative small sample size, replication in other populations with larger sample size and further functional analysis are required for fully understanding the roles of CD3G polymorphisms in predisposition for HCC.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. Although molecular biology of carcinogenesis and tumor progression of HCC has been increasingly understood with intense research in recent years, the molecular and cellular mechanisms of HCC pathogenesis are still poorly understood. In the present study, a case-control study including 390 HCC patients and 431 healthy controls was conducted to investigate the association of HCC susceptibility with the mitochondrial DNA (mtDNA) 9-bp deletion polymorphism in Chinese population. Chi-square testing showed that frequencies of 9-bp one repeat or two repeats were significantly different between HCC and control groups. Carriage of 9-bp one repeat fragment was associated with a significantly increased risk of developing HCC (odds ratio=1.48, 95% confidence interval: 1.03-2.14, p=0.027). Stratification analysis further showed that the differences between cases and controls were more obvious in drinkers than nondrinkers. Computational modeling of the 9-bp deletion polymorphism suggests that the mtDNA sequence without the 9-bp deletion polymorphism lies within a predicted binding site (seed region) for hsa-miR-519c-5p and hsa-miR-526a. Our data suggested that the 9-bp deletion polymorphism in mitochondria may influence HCC risk, likely through specific microRNA-mediated regulation, which was possibly involved in the pathogenesis of HCC. The replication of our studies in other populations with larger sample size is warranted.
