title: [Roles of microRNAs in lymphocytopoiesis and lymphoid malignancies - review].
abstract: microRNAs (miRNAs) are small molecular non-coding RNA with 21-25 nucleotides in a variety of eukaryotic systems, and regulate gene expression at the post-transcriptional level by degrading or translational repressing target messenger RNA (mRNA). Many studies have showed the roles of miRNAs in normal lymphocytopoiesis, giving an interpretative key to the aberrant expression observed in human lymphoid malignancies. The recent advances of understanding the roles of miRNAs in lymphoid malignancies show that miRNAs as tumoral biomarkers can effectively be used for diagnosis, prognosis, and prediction of response to therapy. This review focuses the roles of miRNA in development and differentiation of lymphocytes and the relation of miRNA to lymphoid malignancies.
