Clinical heterogeneity is a major barrier to effective treatment of Chronic Lymphocytic Leukemia (CLL). Emerging evidence suggests that constitutive activation of various signaling pathways plays a role in the heterogeneous clinical outcome of CLL patients. MAPK-Erk signaling represents one such pathway with a demonstrated role in CLL pathogenesis. In this study, we have investigated the role of Sprouty2 (SPRY2) as a negative regulator of receptor and non-receptor tyrosine kinase signaling in the pathogenesis of CLL. We show that SPRY2 expression is significantly decreased in CLL cells, particularly from poor prognosis patients compared to those from good prognosis patients. Over-expression of …
