Association of the eNOS G894T polymorphism with the development and progression of gastric cancer
Objective:To investigate the association of eNOS gene G894T polymorphism and the development and progression of gastric cancer.Methods:PCR-RFLP method was used to determine the genotypes of eNOS G894T gene polymorphism in 324 gastric cancer patients and 200 cancer-free controls in Han Population of Fujian Province.Results:(1)In the case and control group
G/G genotype frequencies were 76.5%(248/324) and 73.0%(146/200)respectively;G/T+T/T genotype frequencies were 23.5%(76/324) and 27.0%(54/200)respectively;G allele frequencies were 88.0%(570/648)and 86.3%(345/400) respectively;T allele frequencies were 12.0%(78/648)and 13.7%(55/400)respectively.The comparisons between the case group and control group showed no significant difference in genotype and allele frequencies(all P>0.05);When case group was subdivided as diffuse-type and intestinal-type
the comparisons between the two subgroups and control group respectively also showed that not any genotype or allele increased the risk of gastric cancer(all P>0.05).(2)No statistically significant correlations existed between eNOS G894T polymorphism and several clinicopathological features of gastric cancer(all P>0.05).Conclusion:No association is found between eNOS gene G894T polymorphism and the development and progression of gastric cancer in Han Population of Fujian Province.
