Abstract

Aim: MicroRNAs (miRNAs) are an abundant class of small non-protein coding RNAs with posttranscriptional regulatory functions as tumor suppressors and oncogenes. Aberrant expression and structural alteration of miRNAs are considered to participate in tumorigenesis and cancer development. It has been suggested that the presence of single nucleotide polymorphisms in precursor miRNAs (pre-miRNAs) can alter miRNA processing, expression, and/or binding to target mRNA and represent another type of genetic variability that can contribute to the susceptibility of human cancers. A G/C polymorphism (rs2910164), which is located in the sequence of miR-146a precursor, results in a change from G:U to C:U in its stem region.
