A small subset of cancer cells that act as tumor initiating cells or cancer stem cells(CSCs) maintain self-renewal and growth promoting capabilities of cancer and are responsible for drug/treatment resistance,tumor recurrence and metastasis. Due to their potential clinical importance,many researchers have put their efforts over decades to unravel the molecular mechanisms that regulate CSCs functions. Micro RNAs(mi RNAs) which are 21-23 nucleotide long,endogenous noncoding RNAs,regulate gene expression through gene silencing at post-transcriptional level by binding to the 3'-untranslated regions or the open reading frames of target genes,thereby result in target mR NA degradation or its translational repression and serve important role in several cellular,physiological and developmental processes. Aberrant mi RNAs expression and their implication in CSCs regulation by controlling asymmetric cell division,drug/treatment resistance and metastasis make mi RNAs a tool of great therapeutic potential against cancer. Recent advancements on the biological complexities of CSCs,modulation in CSCs properties by mi RNA network and development of mi RNA based treatment strategies specifically targeting the CSCs as an attractive therapeutic targets for clinical application are being critically analysed.
