Objective To explore the TXNIP polymorphism in 3′UTR, the methylated CpG island and binding sites of transcription factor in its promoter region. Method The SNPs in TXNIP 3′UTR and their mRNA expressions were ob-tained via online bioinformatics software;And TXNIP promoter sequences were analyzed to predict methylated CpG island and the binding sites of transcription factors. Result The genotypes of SNPs in TXNIP 3′UTR, rs7211, rs7212 and rs4755, are significantly associated with the mRNA expression ( P<0. 05);And the methylated CpG island in promoter re-gion located on 1763-1943 bp. Conclusion With bioinformatics analysis, we can better understand the role of genetic polymorphism and the promoter region in the regulation of gene expression.
