The cellular Src (c-Src) tyrosine kinase is upregulated and believed to play a pivotal role in various human cancers. However, the molecular mechanism underlying c-Src-mediated tumour progression remains elusive. Recent studies have revealed that several microRNAs (miRNAs) function as tumour suppressors by regulating the malignant expression of signalling molecules. Aberrant expression of miRNAs is frequently observed in human cancers and should be exploited to seek related molecular targets. In this review, we focus on miRNAs found to be involved in Src signalling in various cancers. We summarize recent findings on Src-related miRNAs, their target genes, mechanisms behind their interplay and their implications for cancer therapeutics.
Keywords: Src; cancer signalling; mTOR; microRNA; proto-oncogene.
