Purpose: RNase3 is a secretory ribonuclease, which is found in the eosinophilic leukocyte and involved in the innate immune system. Its cytotoxic activity is effective against a wide range of pathogens. We performed a case-control study to examine the relationship between RNase3 polymorphisms and the susceptibility of gastric cancer in Korean people.
Methods: Blood sampling of stomach cancer and healthy persons groups were performed, Taqman in g.-550A>G, polymerase chain reaction-restriction fragment length polymorphism in g.371C>G, and high-resolution melt in g.499C>G were analyzed. The three single nucleotide polymorphisms g.-550A>G, g.371C>G, and g.499C>G in RNase3 and their haplotypes were analyzed.
Results: The genotype and allele frequencies of RNase3 g.-550A>G and g.371C>G were not significantly increased in susceptibility of gastric cancer than control group. But, RNase3 CC genotype was associated with a significantly increased susceptibility of gastric cancer than control group (P=0.002). Also, RNase3 CC genotype was more specifically associated with a significantly increased susceptibility of middle and lower gastric cancer than upper gastric cancer (P=0.002). In haplotype of RNase3 SNP g.-550A, g.371G, and g.499C, there was significantly susceptibility of gastric cancer (P=0.004), and more specific influence on middle and lower gastric cancer than upper gastric cancer (P=0.006 vs 0.054).
Conclusion: RNase3 g.499C>G polymorphism may influence gastric cancers, and have a more specific influence on middle and lower gastric cancer rather than upper gastric cancer. But RNase3 g.-550A>G, g.371C>G polymorphisms need careful interpretation and confirmation in more larger studies.
