Introduction

Aptamers are valuable tools for identifying novel therapeutic targets due to their high affinity and specificity. The relative ease of selection of aptamers binding to complex targets and their lack of immunogenicity have led to the incorporation of aptamers into drug transport vehicles and cell labeling tools. However, their potential as direct anti-cancer therapies remains to be explored. Recent advances in aptamer therapeutics have underscored their potential to meet the need for better therapies in B-cell non-Hodgkin lymphomas (NHL). For example, the aptamer AS1411 binds nucleolin and inhibits the proliferation of multiple leukemia and lymphoma cancer cell lines. The DNA aptamer C10.36 has been shown to selectively bind to Ramos Burkitt lymphoma cells and to be internalized via clathrin-dependent endocytosis. Here we identify the molecular target of C10.36 and explore its potential role as a targeted therapy in NHL.
