Abstract:
MiRNAs are a class of non-coding RNAs acting as gene expression regulators by modulating the lifespan of messenger RNA. Commonly referred to as the most frequent leukemia in the Western world, chronic lymphocytic leukemia (CLL) is a lymphoproliferative malignancy characterized by clonal expansion of CD19, CD23, and CD5-positive mature B-cells. While this pathology is regarded as less aggressive and has a variety of treatment options, the cause of its clinical heterogeneity is not yet understood. Moreover, the prognostic markers and treatment recommendations based on predictive markers are limited. This review aims to investigate some miRNAs that are dysregulated and possibly involved in CLL pathogenesis as a starting point for the proposal of new prognostic and predictive markers and, as more agents targeting miRNA expression become available, their potential role as therapeutic targets.
