摘要
MicroRNAs(miRNAs)are highly deregulated in cancer and play a role in the initiation of tumorigenesis.Recently,miRNAs have attracted attention in gastrointestinal(GI)cancers.Single nucleotide polymorphisms(SNPs)could affect the genes involved in each step of miRNA biosynthesis.Several metaanalyses of case-control studies have assessed the association between miRNA“pathway”gene-SNPs(including biosynthesis regulators and binding sites)and susceptibility to GI cancers.We present in this mini-review the current knowledge on the association between miRNAs“pathway”genes and GI cancer predisposition.The interaction between miRNA/regulators/binding site-SNPs and environmental as well as genomic factors is an interesting field that should be exploited in future studies.
