Abstract:
MicroRNAs (miRNAs) are a small noncoding family of 22 ut RNAs that play an important role in the negative regulation of gene expression at the post-transcriptional level by base pairing to the 3'untranslated region of target messenger RNAs.miRNAs are involved in a variety of basic processes,such as cell proliferation and apoptosis,metabolism and signaling pathways.A lot of studies have indeed described the aberrant expression of miRNAs in human tumors and have investigated their potential role as oncogenes or tumor suppressor genes,depending on the targets they regulate.Furthermore,more and more studies have demonstrated that an important role of miRNAs in anticancer drug resistance and miRNA expression profiling can correlate with the development of anticancer drug resistance.A systematic and intensive study on the mechanisms of miRNA in anticancer drug resistance will provide us a strong rationale for the development of miRNA-based therapeutic strategies aiming to overcome cancer cell resistance.This paper has reviewed the recent development of miRNAs involved in anticancer drug resistance.
