Abstract

The purpose of this study was to evaluate the association of seven VEGF promoter polymorphisms with breast cancer risk in Punjabi population from North West India. We screened DNA samples of 102 sporadic breast cancer patients and 102 unrelated healthy, gender, and age-matched individuals for seven VEGF promoter polymorphisms [−417C/T (rs833062), −172C/A (rs59260042), −165C/T (rs79469752), −160C/T, −152G/A (rs13207351), −141A/C (rs28357093) and −116G/A (rs1570360)] by direct sequencing. The frequency of GG, GA, and AA genotype of −152G/A polymorphism was 26.47 vs 38.34 %, 46.08 vs 51.96 %, and 27.45 vs 9.80 %, in patients and controls, respectively. VEGF −152 AA genotype was significantly associated with increased risk for breast cancer (OR = 4.04, 95 %CI, 1.69–9.68, p = 0.001; recessive model OR = 3.48, 95 %CI, 1.59–7.63, p = 0.001). For VEGF −116G/A polymorphism, G and A allele frequencies were 65.2 vs 76.47 % and 34.8 vs 23.53 % in patients and controls, respectively. Individuals having −116AA genotype (OR = 3.40; 95 %CI, 1.24–9.37; p = 0.014) and A allele (OR = 1.73; 95 %CI, 1.12–2.67; p = 0.012) were associated with increased risk for breast cancer. VEGF −165C/T and −141A/C polymorphisms were associated with reduced risk for breast cancer. There was significantly decreased frequency of CT genotype (4.90 vs 18.63 %; p = 0.002) and T allele (2.45 vs 9.31 %; p = 0.003) of −165C/T polymorphism among breast cancer patients as compared to controls. VEGF −141A and C allele frequency were 96.57 vs 91.18 % and 3.43 vs 8.82 % in patients and controls, respectively. Significant reduced risk for breast cancer was observed with AC genotype (OR = 0.34, 95 %CI, 0.14–0.86; p = 0.019) and C allele (OR = 0.37; 95 %CI, 0.15–0.89; p = 0.023) of −141A/C polymorphism. We did not observe association of VEGF −417T/C, −172C/A, −160C/T polymorphisms with breast cancer risk in the studied subjects (p > 0.05). The VEGF −152G/A and −116G/A polymorphisms were found to be significantly associated with increased risk for breast cancer while −165C/T and −141A/C polymorphisms were found to be associated with decreased risk for breast cancer in Punjabi population from North West India.
