Association of endothelin-converting enzyme-1b C-338A polymorphism with gastric cancer risk: a case-control study.

To investigate the association between endothelin-converting enzyme-1b (ECE-1b) C-338A polymorphism and gastric cancer risk, we conducted a hospital-based case-control study of 256 gastric cancer cases and 256 controls matched on age and gender. The genotypes were identified by polymerase chain reaction-restriction fragment length polymorphism. We found… (More)
