Chronic lymphocytic leukemia (CLL) is the most common type of leukemia among adults in the western world. It is characterized by a malignant clone of B cells in the bone marrow, blood and secondary lymphoid tissues. microRNAs (miRNAs) are a family of small, non-coding RNAs that regulate the expression of target messenger RNAs at the post-transcriptional level. Previous studies have suggested that miRNAs are extensively involved in the proliferation and differentiation of hematopoietic cells. Aberrant expression of certain miRNAs has been observed in CLL. Associations between miRNAs and chromosomal abnormalities suggest that miRNAs may be involved in the pathogenesis of CLL. Moreover, miRNAs may be used as novel biomarkers for the prognosis of CLL. Expression levels of miRNAs are also involved in resistance to chemotherapy drugs. In this article, we review recent developments of miRNAs in the initiation, prognosis and chemoresistance of CLL.
