Abstract
Over the past few years, molecular oncology research has revealed that abnormalities in both protein coding genes (PCGs) and noncoding RNAs (ncRNAs) can be identified in tumors and that the interplay between PCGs and ncRNAs is causally involved in the initiation, progression and metastases of human cancers. MicroRNAs (miRNAs), which are among the most studied ncRNAs, are small 19- to 25-nucleotide genes involved in the regulation of PCGs and other ncRNAs. With the recent findings of miRNAs' involvement in cancer, miRNAs are strongly associated with the pathogenesis in human cancers. In this review, we focus on the possible mechanisms of miRNAs in cancer pathogenesis.
