Abstract
Objective
To assess the association between the C to T transition in the methylenetetrahydro folate reductase gene (MTHFR C677T) and the C to T transition in the serine hydroxymethyltransferase
1
gene (SHMT
1
C1420T) and the increased risk of carcinogenesis of esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA) in a population of high incident region of Northern China.
Methods
The polymorphisms were genotyped by polymerase chain reaction–restriction fragment length polymorphism and PCR-confronting two-pair primers analysis respectively among 1051 cancer patients (584 ESCC and 467 GCA) and 540 healthy controls.
Results
The MTHFR 677T/T genotype significantly increased susceptibility to both ESCC and GCA compared with the C/C genotype, the adjusted OR was 2.13 (95% CI = 1.50–3.02) and 1.28 (95% CI = 1.07–1.53, respectively. For the SHMT
1
C1420T polymorphism, the C/C genotype was significantly associated with the increased risk of ESCC and GCA, compared with the C/T genotype (the adjusted OR = 1.43 and 1.35, 95% CI = 1.02–2.00 and 1.11–1.63, respectively). The interactive influence of the MTHFR and SHMT
1
polymorphisms in the risk of ESCC and GCA was also observed.
Conclusion
The association between the MTHFR C677T and SHMT
1
C1420T polymorphisms and the risk of ESCC and GCA was demonstrated.
