Abstract
Background The relationship between polymorphisms in vascular endothelial growth factor (VEGF) and gastric cancer is still inconclusive. We investigated whether there is an association between VEGF genetic polymorphisms and risk of gastric cancer, and evaluated the recurrence of advanced gastric cancer after curative resection with adjuvant chemotherapy according to VEGF genetic polymorphisms. Methods The association of functional single nucleotide polymorphisms (SNPs) of the VEGF gene (+936C > T, − 634G > C, − 2578C > A, + 1612G > A) were evaluated. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. A total of 151 patients with gastric cancer were enrolled, and the control group consisted of 413 individuals with esophago-gastroduodenoscopy who were randomly selected through health screening. All of the enrolled patients had curative resections with completion of adjuvant capecitabine and oxaliplatin combination chemotherapy and the initial metastatic cases were excluded. During the regular follow-up protocol, the episodes of the recurrence were documented and the specific genotype and allelic frequencies were evaluated. Results As for the cancer risk, there were no significant differences in specific genotypes and allelic frequencies. The mean follow-up period was 28.82 ± 30.92 (12 ~ 72) months and the recurrence rate was 28.3%. In the patients carrying the 936-C allele, the recurrence rate of gastric cancer was high (P = 0.02). Disease-free interval was significantly different between the patients carrying the 936-CC and 936-CT/TT genotype (P = 0.02). Conclusions VEGF 936-C allele is associated with poor prognosis, but not risk of gastric cancer. In the patients carrying the 936-C allele, more potent adjuvant treatment would be considered.

Abstract
Preeclampsia (PE) is a serious pregnancy-specific condition, which originates from placenta and finishes after delivery. The present study has investigated the association between placental VEGF I/D (rs35569394), -1154G/A (rs1570360), and -634G/C(rs2010963) polymorphisms and maternal VEGF -2549 I/D (rs35569394) polymorphism with PE and PE severity. In this case-control study, the maternal blood of 217 women with PE and 210 normotensive pregnant women and the placenta of 84 PE women and 103 normotensive women were collected after delivery. Genotyping was done by PCR or PCR-RFLP methods. The maternal VEGF-2549I/D genotypes were not associated with PE or PE severity. The placental VEGF -2549 I/D genotypes were not associated with PE too; however; the placental VEGF-2549 DD genotype was statistically different between women with severe PE and mild PE or the controls. The placental VEGF -634GC and CC genotypes were significantly higher in PE women and associated with 2.6 and 2-fold higher risk of PE, respectively. The VEGF -634GC and CC genotypes were associated with PE severity. No association was found between placental VEGF -1154G/A polymorphism and PE or PE severity. The placental DGC haplotype of VEGF -2549 I/D, -1154G/A, and -634G/C polymorphisms was associated with 2.9-fold higher risk of PE. However, the placental IAG haplotype was associated with 0.3-fold lower risk of PE. In conclusion, the placental VEGF -2549 DD genotype was associated with severe PE and the placental -634GC and CC genotypes were associated with PE and severe PE. No association was found between VEGF -1154G/A polymorphism and PE or PE severity.

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.

The relation of vascular endothelial growth factor (VEGF) gene polymorphisms on VEGF levels and the risk of vasoocclusive crisis in sickle cell disease. Eur J Haematol 2012; 89:403-9.

Abstract
OBJECTIVE The association of vascular endothelial growth factor (VEGFA) variants and VEGF secretion with sickle cell disease (SCD) vasoocclusive crisis (VOC) was investigated in 210 VOC patients and 114 pain-free control patients. METHODS VEGFA -2578C/A (rs699947), -460T/C (rs833061), -1154G/A (rs15703060), -634G/C (rs2010963), 398G/A (rs833068), 497G/A (rs833070), -583T/C (rs3025020), and 936C/T (rs3025039) were carried out by real-time PCR. RESULTS Higher frequency of rs2010963 C-allele, rs833068 A-allele, and rs3025020 C-allele and significant differences in rs2010963, rs833068, and rs3025020 genotype distribution were seen in VOC than steady-state patients. Increased VOC risk was seen with rs2010963 as heterozygous and more as homozygous, and in rs833068 and rs3025020 homozygous carriers. While there were no differences in VEGF levels between VOC and steady-state controls, there was a progressive decline in serum VEGF in rs2010963 and rs833068 heterozygous and homozygous genotypes, but an opposite trend was seen in VOC patients. Haploview analysis revealed high LD between rs699947, rs833061, rs1570360, rs2010963, rs833068, and rs833070, but weak or no LD between rs3025020 and rs3025039 and other SNPs. Six-locus (rs699947/rs833061/rs1570360/rs2010963/rs833068/rs833070) VEGFA haplotype analysis identified haplotype 111111 to be negatively (OR = 0.68) and haplotype 111222 to be positively (OR = 1.89) associated with VOC. rs2010963, rs833068, and rs3025020 were correlated with VOC type, while rs3025020 was correlated with hospitalization, VOC treatment, and duration. CONCLUSION Specific VEGFA variants contribute to the pathogenesis of SCD VOC.
