  • Association between polymorphism of long non-coding RNA maternally expressed gene 3and risk of gastric cancer

    Objective To explore relationship between long non-coding RNA maternally expressed gene 3 (MEG3) polymorphisms and risk of gastric cancer. Methods One hundred and seventy-two Han patients with gastric cancer (gastric cancer group) and 224 Han individuals for physical examination (control group) in the Yunnan Cancer Hospital from March 2013 to October 2017 were selected as subjects. The rs7158663 and rs4081134 polymorphisms of the MEG3 were genotyped by using a TaqMan technique. The associations between the 2 polymorphisms and the risk of the gastric cancer and its clinical features were analyzed using the SPSS software. Results The frequencies of the AG+AA genotype and the A allele of the MEG3 rs7158663 in the gastric cancer group were significantly higher than those in the control group using the GG genotype and G allele as a reference respectively [adjusted OR=1.71, 95%CI (1.14, 2.56), P=0.010; adjusted OR=1.58, 95%CI (1.15, 2.19), P=0.005] after the Chi-square test and the adjustment of age and gender. The frequencies of the AG+AA genotype and the A allele of the MEG3 rs4081134 had no significant differences between the gastric cancer group and the control group (P>0.017). Moreover, the polymorphisms of the MEG3 rs7158663 and rs4081134 were not associated with the clinical features of the gastric cancer (P>0.017). Conclusion MEG3 rs7158663 AG+AA genotype might be one of susceptibility gene of gastric cancer in Chinese Han population.
