Core Tip

Core tip: Several studies have evaluated an association between single-nucleotide polymorphisms (SNPs) and gastric cancer (GC) risk. Here we used novel approach. Using bioinformatical analysis tools, several SNPs were identified as potential target sites of microRNAs that previously have been linked with gastric carcinogenesis. This study evaluated an association between SNPs in the INSR (rs1051690), IL12B (rs1368439), CCND1 (rs7177), and IL10 (rs3024498) genes and risk of GC in subjects of European descent. The study found that INSR rs1051690 SNP was associated with increased risk of GC, while polymorphisms in IL12B, CCND1 and IL10 genes showed no association with GC.
